RESUMO

BACKGROUND: Observational studies suggest that asthma/wheezing improves after adenotonsillectomy (AT). However, there is a paucity of randomized clinical trial (RCT) specifically studying the effects of AT in asthma/wheezing. Therefore, we conducted a post-hoc analysis of the Childhood Adenotonsillectomy Trial (CHAT), the largest RCT of AT in children with obstructive sleep apnea (OSA) to test the hypothesis that AT would result in fewer wheezing episodes. METHODS: In the CHAT study, 464 children with OSA, aged 5-9 years, were randomized to early AT (n = 226) or watchful waiting with supportive care (WWSC) (n = 227). For this post-hoc analysis, children were categorized as having "any wheezing" versus "no wheezing" at baseline and at 7 months of follow-up. A multivariate analysis was conducted to evaluate the association between "any wheezing" at follow-up and treatment group after controlling for several potential confounders. RESULTS: Children in the "any wheezing" group were predominantly black, had more allergic rhinitis, eczema, second-hand smoke exposure, body mass index, apnea-hypopnea index (AHI), and had lower maternal education and family income than those in the "no wheezing group." In the AT arm, the prevalence of wheezing significantly decreased from baseline to follow-up (at 7 months of the intervention) (47% vs. 21.6%, p < 0.001); while in the WWSC arms did not change (45.2% vs. 43.1%, p = 0.67). In the multivariate analysis, second-hand smoke exposure, wheezing at baseline, and belong to WWSC arm (odds ratio: 3.65 [2.16-6.19]) increase the risk of wheezing at follow-up. CONCLUSION: This study demonstrated that AT decreased the risk of wheezing at 7 months of follow-up.

RESUMO

Abstract Introduction Palatine and pharyngeal tonsils are the first line of defense against pathogens. Clinically, two alterations may require surgical removal of the tonsils: hypertrophy and recurrent tonsillitis. The two conditions probably result from a dysfunction of the immune system. Objective To evaluate possible differences in the plasma levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10) in patients submitted to adenotonsillectomy. Methods Prospective, longitudinal study with 25 children undergoing adenotonsillectomy separated into 3 different groups: recurrent tonsillitis (RT), composed of 7 patients; recurrent hypertrophy tonsillitis (RTTH), with 8 patients; and the tonsillar hypertrophy (TH) group, with 10 patients. Ten healthy control children (SD) were also included in the study. Peripheral blood was collected, and plasma was separated to measure the levels of TNF-α, IL-6, and IL-10. The Mann-Whitney test was used for statistical analysis. Results The plasma level of IL-6 was higher in the RT (p= 0.0394) and TH (p= 0.0009) groups, compared with the control group. The TH group also had higher levels of IL-6 than the RT group (p= 0.039). The IL-6/IL-10 ratio was higher in the RT (p= 0.029) and TH (p= 0.0005) groups compared with the control group. Between the RT and RTTH groups, the IL-6/IL-10 ratio was higher in the RT group, with a statistically significant difference (p= 0.0091). Conclusion Patients with a history of chronic tonsillitis had higher levels of IL-6, compared with the control group.

RESUMO

Introduction Intra and postoperative bleeding are the most frequent and feared complications in adenotonsillectomy (AT). Tranexamic acid (TXA), which is known for its antifibrinolytic effects, has a proven benefit in reducing bleeding in hemorrhagic trauma and cardiac surgery; however, the effectiveness and timing of its application in AT have not yet been established. Objectives We aimed to evaluate the efficacy of TXA in controlling bleeding during and after AT and assess its possible adverse effects in children. Methods The present randomized, controlled, double-blind clinical trial included 63 children aged 2 to 12 years. They were randomly assigned to receive either intravenous TXA (10 mg/kg) or placebo 10 minutes before surgery. The volume of intraoperative bleeding, presence of postoperative bleeding, and adverse effects during and 8 hours after the surgery were assessed. Results No difference in bleeding volume was noted between the 2 groups (mean, 122.7 ml in the TXA group versus 115.5 ml in the placebo group, p = 0.36). No intraoperative or postoperative adverse effects were noted because of TXA use. Furthermore, no primary or secondary postoperative bleeding was observed in any of the participants. Conclusion In our pediatric sample, TXA (10 mg/kg) administration before AT was safely used, without any adverse effects. It did not reduce the bleeding volume in children during this type of surgery. Future studies should assess the use of higher doses of TXA and its administration at other time points before or during surgery.

RESUMO

Resumen El síndrome de apnea e hipoapnea obstructiva del sueño (SAHOS) en niños forma parte del espectro de trastornos respiratorios del sueño en la infancia. Tiene una prevalencia entre un 0,69% y 4,7% en la población infantil con una mayor incidencia entre los 2 y 6 años debido principalmente a la hiperplasia adenoamigdaliana y constituye una importante causa de morbilidad neurocognitiva y conductual en quienes lo padecen. El principal tratamiento quirúrgico del SAHOS infantil lo constituye la adenoamigdalectomía, cirugía que logra la resolución de los síntomas entre un 20% y 75% de los pacientes. Los pacientes con comorbilidades asociadas tales como obesidad, enfermedades neuromusculares y alteraciones craneofaciales, entre otras, tienen mayor riesgo de SAHOS persistente. En la presente revisión de la literatura abordaremos el diagnóstico, enfrentamiento, estudio y tratamiento del SAHOS persistente posadenoamigdalectomía en niños.

Abstract Obstructive sleep apnea syndrome (OSA) in children is part of the spectrum of respiratory sleep disorders in childhood. It has a prevalence between 0.69 and 4.7% in pediatric population, with a higher incidence between 2 and 6 years old, mainly due to adenotonsillar hyperpla-sia. OSA constitutes an important cause of neurocognitive and behavioral morbidity. The main surgical treatment for childhood OSA is adenotonsi-llectomy, which resolves symptoms in 20%-75% of patients. Patients with associated comorbidities such as obesity, neuromus-cular diseases, and craniofacial malformations are at higher risk of having persistent OSA. In this literature review, we will discuss the diagnosis, evaluation and treatment of persistent OSA after adenotonsillectomy in children.

RESUMO

Objetivo: documentar de forma sistemática o padrão de desenvolvimento pôndero-estatural de pacientes submetidos à adenoamigdalectomia. Métodos: coleta de dados secundários dos prontuários de pacientes atendidos no ambulatório de Otorrinolaringologia Pediátrica, antes e depois da cirurgia de adenoamigdalectomia. Resultados: de forma individual, os pacientes apresentaram elevação no escore Z e percentis das variáveis ao peso e a altura no período entre as análises. Especificamente em relação ao peso, a média antes do procedimento e quatro meses depois do procedimento foi, respectivamente, de 29,1 kg e 32,8 kg; no que diz respeito à altura, a média foi de 1,22 m e 1,25 m, respectivamente. Ao aplicar o Teste T de Student foi possível notar significância estatística para ambas as variáveis em estudo. Aspecto não percebido ao avaliar os indivíduos reunidos em grupos etários (pré-escolares, escolares e adolescentes). Conclusões: as crianças submetidas à adenoamigdalectomia apresentaram ganho pôndero-estatural após a cirurgia. A atuação cirúrgica diante do diagnóstico da hipertrofia e da hiperplasia das amígdalas e tonsila faríngea deve ser precoce, desde que haja indicação formal, a fim de evitar a manutenção do atraso no crescimento nesses pacientes.

Aims: to systematically document weight and height development in children after adenotonsillectomy. Methods: analysis of secondary data from the Pediatric Otorhinolaryngology clinic patient's medical records before and after adenotonsillectomy. Results: regarding weight, the average before the procedure and four months and the average after the procedure were, respectively, 29.1 kg and 32.8 kg; as regards height, the averages were 1.22 m and 1.25 m, respectively. By applying the Teste T de Student it was possible to notice statistical significance for both variables under study. Conclusions: children exhibited statistically significant weight and height gain after surgery. Surgical treatment should be performed early after the diagnosis of pharyngeal tonsil and tonsils hypertrophy and hyperplasia provided in case of a formal indication in order to avoid the maintenance growth retardation in these patients.

RESUMO

RESUMEN La estenosis faríngea es una complicación muy poco frecuente de la adenoamigdalectomía. Consiste en un estrechamiento de la vía aerodigestiva superior secundaria a la adhesión parcial o total de las estructuras que componen la orofaringe producto de una disección extensa al realizar amigdalectomía. El objetivo de este trabajo es presentar tres casos clínicos tratamiento y correspondiente técnica quirúrgica. Se describen tres pacientes operados durante la edad preescolar de adenoamigdalectomía, que cursaron en el posoperatorio con estenosis faríngea. Todos presentaron roncopatía severa, respiración oral y resonancia hiponasal. La nasofibroscopía evidenció estrechez faríngea en distintos grados. A todos se les realizó resección del tejido cicatricial y faringoplastía con colgajo miomucoso y posterior rehabilitación con bulbo faríngeo. El uso de colgajos faríngeos posterior a la liberación de adherencias posadenoamigdalectomía permite aportar tejido sano a zonas cruentas, evitando la formación de nuevas adherencias y restituyendo la permeabilidad oronasal. El bulbo faríngeo es fundamental para mantener un apropiado lumen y manejo de la cicatrización en el posoperatorio. La técnica de colgajo faríngeo lateral, que interpone mucosa faríngea sana para la cobertura del lecho cruento, constituye una alternativa quirúrgica eficaz para resolver la estenosis faríngea posquirúrgica.

ABSTRACT Pharyngeal stenosis is a very rare complication of adenotonsillectomy. It is caused by a narrowing of the upper aerodigestive pathway secondary to the total or partial adhesion of the retropharyngeal structures as a result of extensive dissection during tonsillectomy. Our aim is to present three consecutive clinical cases of pharyngeal stenosis after adenotonsillectomy, discuss its treatment and corresponding surgical technique. We present three infants with adenotonsillectomy with postoperative pharyngeal stenosis. All had severe snoring, oral breathing and hyponasal resonance. The nasofibroscopy showed pharyngeal obliteration in several degrees. All patients underwent scar tissue resection and pharyngoplasty with myomucosal flap and subsequent use of pharyngeal bulb. The use of pharyngeal flaps after release of pharyngeal adhesions allows to provide healthy tissue to row areas, avoiding new postoperative adhesions and providing adequate oronasal permeability. The pharyngeal bulb is essential to maintain permeability and management of scarring in the postoperative period. The technique of lateral pharyngeal flap, which aims to interpose healthy pharyngeal mucosa to cover the bloody bed, is an effective therapeutic alternative to solve post-surgical pharyngeal stenosis.

RESUMO

RESUMEN Introducción: El trastorno respiratorio del sueño (TRS) afecta al 2% a 3% de la población pediátrica, siendo la hiperplasia adenoamigdalina (HAA) su principal causa. Se ha observado un aumento en los niveles de leucotrienos excretados en orina (LTU) en estos pacientes, los cuales se correlacionarían con la severidad de la enfermedad. Objetivo: Determinar el nivel de LTU en niños con TRS e HAA antes y después de adenoamigdalectomía (AA), y en controles sanos. Correlacionar los niveles de LTU con los síntomas de TRS. Material y método: Estudio prospectivo. Se incluyeron pacientes con TRS e HAA (n =12) y controles sanos (n =12). Se determinó la concentración de LTU en ambos grupos de forma basal y un mes después de cirugía en el grupo con TRS. Resultados: No hubo diferencias en los niveles de LTU antes y después de AA. Tampoco existieron diferencias entre el grupo control y grupo TRS previo a la cirugía. No se encontró asociación entre LTU y la severidad de síntomas respiratorios. Conclusión: Los LTU no se encuentran elevados en pacientes con TRS e HAA, no disminuyen luego de AA y no se correlacionan con la severidad de los síntomas. La medición de LTU no sería una herramienta útil en la evaluación de pacientes con TRS. Nuevos estudios son necesarios para evaluar el rol de los leucotrienos en esta enfermedad.

ABSTRACT Introduction: Sleep disorder breathing (SDB) affects 2%-3% of the pediatric population, being adenotonsillar hyperplasia (ATH) its main cause. An increase in the levels of urinary leukotrienes (ULT) has been measured in these patients, which could be correlated with the severity of the disease. Aim: To determine the level of ULT in children with SDB and ATH before and after adenotonsillectomy, and healthy controls. To correlate the levels of ULT with symptoms of SDB. Material and method: prospective study. SDB and ATH patients (n =12) and healthy controls (n =12) were included. The concentration of ULT in both groups was determined, before surgery and after a month of surgery. Results: There were no differences in the levels of ULT before and after tonsillectomy in the studied group. There were also no differences between the control group and the SDB group. No association was observed between the level of ULT and the severity of respiratory symptoms. Conclusions: ULT are not elevated in patients with SDB and ATH and they do not decrease after adenotonsillectomy. ULT are not correlated with the severity of the symptoms of SDB. The measurement of ULT would not be a useful tool in the evaluation of patients with SDB. New studies are needed to assess the role of the role of leukotrienes in this disease.

RESUMO

Resumen Introducción: En población pediátrica con malnutrición por exceso, existe controversia respecto al rol de la hiperplasia adenoamigdalina en la etiología de los trastornos del sueño y de la efectividad de la adenoamigdalectomía sobre dicha sintomatología. Objetivo: Comparar la efectividad de la adenoamigdalectomía entre pacientes pediátricos eutróficos y con malnutrición por exceso sometidos a adenoamigdalectomía por hiperplasia adenoamigdalina, en relación a la disminución de la sintomatología. Materiales y método: Estudio retrospectivo mediante revisión de fichas clínicas entre junio de 2016 y enero de 2017 de pacientes operados de adenoamigdalectomía por hiperplasia adenoamigdalina sintomática. Se clasificaron los pacientes de acuerdo a edad y estado nutricional en 4 grupos y se evaluó la resolución de la sintomatologia mediante interrogación a padres/tutores. Resultados: Se incluyeron 98 pacientes, con una edad media de 6,3 años. 44,9% de los pacientes fueron eutróficos y 55,1% con malnutrición por exceso. El análisis estadístico entre pacientes eutróficos y aquellos con malnutrición no demostró diferencias significativas en relación a la resolución de la sintomatología. Conclusión: La adenoamigdalectomía por hiperplasia adenoamigdalina sintomática se asocia a una reducción de la frecuencia de roncopatía con pausas en pacientes pediátricos, independientemente del estado nutricional.

Abstract Introduction: In pediatric population with malnutrition by excess, the role of the adenotonsillar hyperplasia in the etiology of breathing-related sleep disorders, and the effectivity of the adenotonsillectomy for reducing symptoms remains controversial. Aim: To compare and evaluate the effectiveness of the adenotonsillectomy between eutrophic and malnutrition by excess pediatric patients submitted to adenotonsillectomy by adenotonsillar hyperplasia, regarding to symptoms resolution. Material and method: A retrospective study was performed collecting data from clinical records between June 2016 and January 2017 of patients submitted to adenotonsillectomy by symptomatic adenotonsillar hyperplasia. Patients were assigned to 4 groups according to age and nutrional status and the rate of symptoms resolution was evaluated through interrogation to parents/guardians. Results: We included 98 patients, with an average age of 6.3 years. A 44.9% of patients were eutrophic and 55.1% had malnutrition by excess. Comparing eutrophic and malnutrition by excess patients, no significant differences were observed regarding to symptoms resolution. Conclusion: The adenotonsillectomy by symptomatic adenotonsillar hyperplasia was associated to an amelioration of the rate of snoring and respiratory pauses during sleeping in pediatric patients, independently of the nutritional status.

RESUMO

BACKGROUND: It is recognized that adenotonsillar hypertrophy leads to muscular and functional changes in face, and that adenotonsillectomy is associated to improvement in this condition. However, the ideal interval one should wait until this spontaneous recovery is not well defined, neither if this recovery is expected to be complete or partial. OBJECTIVE: To compare the muscular and functional changes in face of children prior and after adenotonsillectomy in a monthly evaluation. METHODS: 8 children aged from 4 to 6 years were prospectively studied. All patients underwent adenotonsillectomy, and were assessed before and monthly-after surgery up to 6 months, through the Protocol of Orofacial Myofunctional Evaluation with Scores (OMES). RESULTS: There was a progressive improvement in OMES score in all measured parameters, including the "mobility" and "posture" sub-tests; this improvement was significant at the first month after surgery. The sub-test "function" was not affected by surgery. Improvement continued from the first to the sixth month after surgery, although it was not significant between these two periods. Additionally, all parameters remained altered after the final evaluation at six months. There was a significant correlation between the improvement in "mobility" sub-test and in total score of OMES. CONCLUSION: We observed a partial recovery in facial muscular and functional changes following adenotonsillectomy, particularly during the first month after surgery. This improvement was especially observed in the "mobility" and "posture" sub-tests. We conclude that waiting for a spontaneous muscular and functional facial recovery during the first month post-operatively seems reasonable. Nevertheless, after this period, if the patient fails to achieve recovery, it may be advised that this child should undergo myofunctional therapy.

RESUMO

STUDY OBJECTIVES: To describe characteristics and surgical and clinical outcomes of obese children with obstructive sleep apnea (OSA). METHODS: At our institution from 2000 to 2010, 143 obese children with an overnight polysomnography (OPSG) diagnosis of OSA, excluding children with comorbidities, were identified. Relationships between demographics, clinical findings, and the severity of OSA were assessed. Presurgery and postsurgery OPSG indices were compared. We defined cure as an apneahypopnea index (AHI) < 1.5/h on the postsurgery OPSG, and we compared the cure rates of different surgeries. RESULTS: A total of 143 children, median age 12.4 y (interquartile range [IQR] 9.6-14.9) and BMI z-scores 2.8 (IQR 2.6-2.9), were included. Seventy-eight (55%) (Median age 12 y [IQR 9-15]) underwent surgery: 1 had tonsillectomy; 1 tonsillectomy + uvulopharyngopalatoplasty (UPPP); 23 adenotonsillectomy (AT); 27 AT + UPPP; 11 adenoidectomy + UPPP; 8 UPPP; and 7 AT + turbinate trim ± tongue base suspension. Overall, surgery cured 19 children (26%), but AHI improved in the majority of children (p = 0.001). Similarly, the arousal index, PETCO2, and SpO2 nadir improved significantly (p < 0.002, p = 0.019, p < 0.001, respectively). AHI improved significantly in children with mild-to-moderate OSA in comparison to severe OSA (p < 0.001). Children with enlarged tonsils and no history of prior surgery benefitted more often from surgery (p < 0.004 and p = 0.002, respectively). AT was the only surgery reducing the AHI significantly (p = 0.008). Children did not lose weight despite intervention. Adherence with PAP was poor. CONCLUSIONS: Surgery improved OPSG indices in the majority of obese children with OSA.

RESUMO

Abstract The mucopolysaccharidoses (MPSs) are a group of inherited, metabolic disorders characterized by progressive multisystem accumulation of partially degraded glycosaminoglycans. This manifests with multilevel airway obstruction, presenting with obstructive sleep apnea (OSA). We systematically reviewed the literature to determine the severity and prevalence of OSA in MPS based on polysomnography analysis. Fifteen studies with 294 participants met the inclusion criteria for review. The pretreatment prevalence of OSA in MPS was 81% with a mean apnea-hypopnea index (AHI) of 10.4. Patients with MPS I are most significantly affected, with 75% suffering with moderate to severe OSA (mean AHI, 16.6). Enzyme replacement therapy (ERT) results in an almost significant reduction in OSA in MPS I (P = .06), while adenotonsillar surgery significantly improves AHI (P = .002). Obstructive sleep apnea least affects MPS III. There is a lack of long-term post-ERT and hematopoietic stem cell transplant data relating to OSA outcomes in this population, with further prospective studies required to determine the ongoing response to treatment.

RESUMO

Antecedentes: la adenoamigdalectomía como toda intervención presenta complicaciones como hemorragias e infecciones del sitio quirúrgico, y el dolor posoperatorio representa su morbilidad principal. Las infecciones no están bien definidas y se interpretan como síndrome febril, incremento del dolor posoperatorio, retraso en el inicio de la dieta habitual e incluso como un factor de riesgo para sangrados posquirúrgicos. La hemorragia se clasifica como primaria o secundaria según se produzca o no dentro de las primeras 24 hs, y como mayor cuando requiere de una reintervención quirúrgica. No existe evidencia que avale la prescripción antibió- tica durante el perioperatorio; no obstante, es una práctica extendida. Algunos autores sostienen que su empleo disminuiría la morbilidad y las complicaciones posquirúrgicas; no obstante estudios recientes concluyen que no presentan un efecto significativo en la reducción del dolor, retorno a la dieta habitual o riesgo de sangrado posoperatorio...

Introduction: adenotonsillectomy as any intervention has complications such as bleeding and surgical site infections, and postoperative pain is the main morbidity. Infections are not well defined, they are considered as febrile syndrome, increase of postoperative pain, delayed start of regular diet and even as a risk factor for postoperative bleeding. Bleeding is classified as primary or secondary as occurs or not within the first 24 hours; and greater, when required reoperation. There is no evidence to support antibiotic prescriptions during the perioperative period, however its use is widespread. Some authors argue that its use would decrease the morbidity and postoperative complications, however recent studies conclude that do not have a significant effect on reducing pain, return to normal diet or risk of postoperative bleeding...

RESUMO

Introducción: el síndrome de apnea/hipopnea del sueño infantil se asocia a numerosos resultados adversos a nivel cognitivo y conductual. El factor de riesgo más comúnmente identificado para presentar síndrome de apnea/hipopnea del sueño es la hipertrofia adenoamigdaliana, para el cual el tratamiento primario es la adenoamigdalectomía. Objetivo: evaluar la eficacia de la adenoamigdalectomía temprana versus la conducta expectante, en lo que respecta a factores cognitivos, conductuales, calidad de vida y sueño, en niños con síndrome de apnea/hipopnea del sueño. Pacientes y método: se analiza críticamente el artículo de Marcus (2013), estudio multicéntrico, enmascarado simple, aleatorizado, controlado, en siete centros de estudio del sueño. Resultados: en un seguimiento a siete meses, la proporción de remisión espontánea en el grupo control de parámetros polisomnográficos sugiere que 46 por ciento de los niños revierten espontáneamente las alteraciones, efecto que se observó en 79 por ciento de los niños en el grupo intervenido. Conclusión de los revisores: la cirugía adenoamigdaliana para el tratamiento de la apnea obstructiva del sueño en escolares no mejora significativamente la atención o la función ejecutiva, pero sí mejora algunos desenlaces de comportamiento, calidad de vida y variables polisomnográficas. Sin embargo, esta mejoría se aprecia en una alta proporción de niños que no recibieron el tratamiento, mejoría principalmente evidenciada en las variables polisomnográficas. Por lo tanto, no sería un requisito indispensable el realizar esta cirugía para revertir dicho cuadro clínico.

Introduction. Obstructive sleep apnea hypopnea syndrome (OSAHS) in children is associated with numerous adverse cognitive and behavioral consequences. The most common risk factor identified for OSAHS is tonsillar enlargement, and primary treatment is adenotonsillectomy. Aim. To compare the efficacy of early adenotonsillectomy versus watchful waiting, on cognitive, behavioral, quality of life and sleep outcomes in children with OSAHS. Patients and Methods. We critically appraised the Marcus (2013) article, a multicenter, single masked, randomized, controlled study in seven sleep centers. Results. After a seven month follow-up, the rate of spontaneous remission in polysomnographic parameters control group shows that 46 percent of children spontaneously revert untoward outcomes, compared to 79 percent of children in the intervention group. Reviewer’s conclusion. Adenotonsillar surgery for the treatment of obstructive sleep apnea in school-age children does not significantly improve attention or executive function, but it does improve some behavioral outcomes, quality of life, and polysomnographic variables. However, this improvement was also observed in a high proportion of children who received no treatment, mainly regarding polysomnographic variables. Thus surgery does not appear to be necessary to reduce symptoms.

RESUMO

Introdução: Distúrbios respiratórios obstrutivos (DRO) são frequentes em crianças e têm como sua principal causa a hipertrofia das tonsilas. A enurese noturna tem sido associada aos DRO, causando assim importante impacto psicossocial. Objetivo: Avaliar a associação entre enurese e DRO em crianças e sua possível melhora após adenoidectomia e/ou tonsilectomia. Métodos: Foram estudadas 138 crianças do Ambulatório de Distúrbios do Sono, com idade entre 5 e 12 anos, com indicação de adeno e/ou tonsilectomia por DRO. Foram analisadas variáveis como: sexo, idade e presença de enurese. As crianças foram reavaliadas três a seis meses após o tratamento cirúrgico. Resultado: Dentre as 138 crianças, 31 (22,5%) apresentavam enurese noturna. Houve predomínio na faixa etária de cinco a sete anos, com distribuição igual entre os gêneros. Houve melhora da enurese em 21 (67,7%) dos pacientes após o procedimento cirúrgico, em sete (70%) das dez crianças nas quais persistiu a enurese, também houve persistência dos roncos. Conclusão: A enurese noturna é frequente em crianças com DRO e pode ter melhora após tratamento da causa da obstrução respiratória, sugerindo interação entre SAOS e enurese noturna.

RESUMO

Introdução: A síndrome de apneia-hipopneia obstrutiva do sono está relacionada a complicações cardiorrespiratórias. O conhecimento de sua fisiopatologia e possíveis complicações pode ajudar a reduzir sua morbimortalidade. Objetivos: Relatar casos de pacientes com distúrbios respiratórios obstrutivos do sono que apresentaram complicações cardiopulmonares com necessidade de tratamento em unidade de terapia intensiva. Casos: Relatamos dois casos de crianças sem diagnóstico prévio de SAHOS que deram entrada no serviço de emergência com o quadro clínico de complicação cardiopulmonar e necessidade de internação em UTI, com melhora clínica após adenotonsilectomia. Em um terceiro caso houve descompensação cardiopulmonar no pós-operatório imediato de adenotonsilectomia. Conclusões: Pediatras e otorrinolaringologistas devem estar atentos às manifestações clínicas mais graves da síndrome de apneia-hipopneia obstrutiva do sono. Um encaminhamento precoce para tratamento e cuidados pré e pós-operatórios são essenciais para evitar complicações graves.

RESUMO

Introdução: A hiperplasia adenotonsilar é a causa mais comum de obstrução respiratória em crianças originando um grupo variado de anormalidades como ronco e síndrome da apneia obstrutiva do sono, com elevada reincidência de infecções das vias aéreas superiores e uso frequente de antibióticos. Em certos casos, a adenotonsilectomia é o melhor tratamento. Objetivo: Analisar o efeito da adenotonsilectomia na qualidade de vida de crianças com hiperplasia adenotonsilar. Método: Cinquenta e um pais ou responsáveis de crianças submetidas a adenotonsilectomia foram entrevistados 12 a 18 meses após a cirurgia através do questionário sobre qualidade de vida desenvolvido por De Serres et al., que inclui os domínios: sofrimento físico, distúrbios do sono, problemas de fala e deglutição, desconforto emocional, limitação das atividades e preocupação do responsável. Foram incluídos os domínios: prevalência de rinite, episódios de infecções de vias aéreas superiores e uso de antibioticoterapia antes e após o procedimento cirúrgico. Resultados e Conclusão: Correlacionando-se os domínios entre si, observamos que a adenotonsilectomia melhorou a qualidade de vida das crianças, a longo prazo, em especial entre distúrbios do sono, como diminuição do ronco (4,16±1,47 vs 0,43±0,96; *p< 0,001), significativa queda do número de tonsilites (4,43±1,14 vs 0,61±0,94 *p< 0,001) e menor uso de antibióticos (4,43±1,14 vs 0,59±0,90; p< 0,001), quando comparado antes e após a cirurgia. No entanto, a melhora foi menos significativa em crianças com sintomas de rinite (8,82±1,81 vs 9,71±0,68 *p= 0,007), comparado as crianças sem rinite e em meninos que meninas (9,13±1,48 vs 9,85±0,49; *p= 0,02).

Introduction: The adenotonsillar hyperplasia is the most common cause of breathing obstruction in children and leads to a variable group of abnormalities such as snoring and sleep obstructive apnea syndrome, with a high recurrence of infection in the upper airways and frequent use of antibiotics. In certain cases, the adenotonsillectomy is the best treatment. Objective: To analyze the effects of adenotonsillectomy onto the life quality of children with adenotonsillar hyperplasia. Method: Fifty-one parents of children submitted to adenotonsillectomy were interviewed 12 to 18 months after the surgery, by means of the questionnaire about life quality, developed by De Serres et al., which includes the following domains: physical suffering, sleep disorders, problems of lack of deglutition, emotional discomfort, limitation of activities and parents concerns. The following domains were included: prevalence of rhinitis, episodes of infections of the upper airways and use of antibiotic therapy before and after surgical procedure. Results and Conclusion: By relating the domains, we observed that the adenotonsillectomy improved the children's life quality on a long term basis, 1.47 vs.±specially sleep disorders such as diminishing of snore (4.16 0.96; *p±0.43< 0.001), significant fall on the number of tonsillitis (4.43±1.14 vs. 0.61±0.94 *p< 0,001) and lower use of antibiotics (4.43±1.14 vs. 0.59±0.90; p< 0.001), when compared before and after the surgery. However, the improvement was less significant in children with symptoms of rhinitis ((8.82±1.81 vs. 9.71±0.68 *p= 0.007), compared to children without rhinitis and between boys and girls (9.13±1.48 vs. 9.85±0.49; *p= 0.02).

RESUMO

A observação clínica diária do retardo de crescimento pôndero-estatural em crianças portadoras de hipertrofia obstrutiva das tonsilas faríngeas e palatinas é prática rotineira na otorrinolaringologia pediátrica e a correção cirúrgica dessa condição, em tempo hábil, através da adenotonsilectomia permite a retomada desse crescimento ("catch up growth"). OBJETIVO: Investigar o real ganho pôndero-estatural presente nessa população quando tratadas cirurgicamente. MATERIAL E MÉTODO: Através de um estudo clínico prospectivo, acompanhou-se durante 6 (seis) meses dois grupos de crianças portadoras de hipertrofia tonsilar faringopalatina, sendo o grupo 1 submetido à intervenção cirúrgica e o grupo 2, não. Todos os pacientes passaram pela aferição das medidas antropométricas (peso e altura), incluindo seus percentis para idade, no início e ao fim dos 6 (seis) meses. RESULTADOS: Enquanto o grupo 1 aumentou sua média final de altura em relação à média inicial em 6,66cm, o grupo controle aumentou sua média em 1,9cm (p=0,0004). Em relação ao peso, o grupo 1 aumentou em média 2150g, sendo que o grupo 2 apresentou aumento médio de 690g (p=0,0010). CONCLUSÃO: As crianças submetidas à adenotonsilectomia adquirem um maior potencial de crescimento pôndero-estatural em relação às crianças que não foram tratadas cirurgicamente.

The daily clinical observation of weight-height growth delays in children with obstructive hypertrophy of the pharyngeal and palatine tonsils is a workaday practice in pediatric otorhinolaryngology, and the surgical correction of this condition, when properly done in time, through adenotonsillectomy, can lead to a "catch up growth". AIM: To investigate the real weight-height gain present in this population when they are surgically treated. MATERIALS AND METHODS: Through a clinical prospective study, two groups of children carrying pharyngopalatine hypertrophy were followed up: group 1 was submitted to surgical intervention, and group 2 was not. All patients underwent standardization of anthropometrical measurements (weight and height), including their age-related percentiles, in the beginning and at the end of 06 (six) months. RESULTS: While group 1 increased its height average in relation to the initial average in 6.66cm, the control group increased its average in 1.9cm (p=0.0004). In relation to weight, group 1 increased 2150g in average, while group 2 presented an average increase of 690g (p=0.0010). CONCLUSIONS: The children that underwent adenotonsillectomy acquired a higher weight-height growth potential in relation to those children who were not operated.
