RESUMO

OBJECTIVES: Oronasal fistulas are common sequelae following cleft lip and palate surgery and can significantly impact a patient's quality of life. They result from various factors, including surgical techniques, tissue management, and patient-specific factors. This case report explores the modern approach to oronasal fistula closure using periodontal plastic surgery principles. MATERIALS AND METHODS: The report presents two cases of patients with oronasal fistulas due to previous maxillofacial surgical intervention. These patients underwent microsurgical procedures that involved partial flap thickness preparation of the fistula areas, the use of connective tissue grafts from the palate, and meticulous suturing techniques to ensure graft integrity. The procedures were performed in stages, and postoperative care was provided. RESULTS: Both cases demonstrated successful fistula closure and graft survival. The patients reported improvements in breathing, speech, aesthetics, and quality of life. The second case also included guided bone regeneration and implant placement. CONCLUSIONS: Oronasal fistulas resulting from maxillofacial surgery can be effectively treated using periodontal plastic surgery techniques, significantly improving patients' quality of life and aesthetic outcomes. This approach represents a valuable addition to the existing repertoire of oronasal fistula closure methods.

RESUMO

Periodontal disease is one of the main affections of the oral cavity of dogs. Its main complication is the formation of periapical abscess, which, when affecting the maxillary canine teeth, can lead to the formation of oronasal fistulae. The objective of this study was to evaluate the efficiency of self-curing glass ionomer cement, covered by photopolymerizable adhesive, as a protective element for mucoperiosteal or gingival flap sutures in oral surgery of dogs. We studied 15 dogs from the clinical routine of the dental service of a teaching veterinary hospital, which needed oral surgeries to correct oronasal fistulae, defects or oral cavity communications, regardless of the causal agent. Group one (G1) was composed of seven animals that presented oronasal fistulae after the extraction of maxillary canine teeth compromised by severe periodontal disease. These fistulae were reduced by the double-mucoperiosteal-flap technique, 15 days after the dental extraction. Group two (G2) was composed of five other dogs that presented oronasal fistulae after the extraction of maxillary canine teeth compromised by severe periodontal disease. In this group, the fistulae were reduced by the single-flap technique, immediately after the dental extraction. Group three (G3) was composed of three animals, two of which presented oronasal fistulae due to maxillary fracture and the third one after excision of oral neoplasia. In all groups, simple interrupted sutures were used with 3.0 nylon, and a thin layer of self-curing glass ionomer cement was applied immediately over the operated area. After cement's settling time, a thin layer of photopolymerizable adhesive was applied to the already polymerized cement. In G1, the protective cement was removed on average at 15 (±2) postoperative days, in G2 at 6 (±1) days and in G3 at 11 (±9) days. In the postoperative period, the animals received antibiotics and anti-inflammatory drugs, and they received their usual dry dog food diet. No Elizabethan collar or any other protective measure was used for suturing or the surgical wound. The result was healing of 100% of the oronasal fistulae, without suture dehiscence or the need for new surgical interventions. Thus, it was concluded that the use of self-curing glass ionomer cement covered by photopolymerizable adhesive was fully satisfactory, providing protection of sutures and surgical wounds and showing the potential for routine use in oral surgery in dogs.

RESUMO

Objetivo: Las comunicaciones bucosinusales y buco- nasales son condiciones patológicas que se caracterizan por la presencia de una solución de continuidad entre la cavidad bucal y el seno maxilar o la cavidad nasal respectivamente. Una vez que se ha instalado una comunicación es deseable ce- rrar este defecto, evitando así la infección del seno maxilar y posibles dificultades en la deglución, fonación y masticación. Se han propuesto diferentes tratamientos para su resolución, algunos no quirúrgicos y otros quirúrgicos. Los quirúrgicos pueden realizarse desplazando tejidos locales, regionales o injertando. El presente trabajo tiene como objetivo presentar situaciones clínicas de comunicaciones bucosinusales y buco- nasales con diferentes etiologías y sus distintos tratamientos según tamaño y ubicación del defecto. Casos clínicos: Se identificaron pacientes que asistie- ron al Servicio de Cirugía Maxilofacial del Hospital Piñero presentando cuatro comunicaciones bucosinusales agudas y crónicas y una comunicación buconasal crónica. Los casos analizados fueron tratados de manera quirúrgica utilizando di- versos colgajos según tamaño y ubicación del defecto (AU)

Aim: Oroantral and oronasal communications are patho- logical conditions characterized by the presence of a solu- tion of continuity between the oral cavity and the maxillary sinus or nasal cavity respectively. Once a communication has been installed, it is desirable to close this defect, thus avoid- ing infection of the maxillary sinus and possible difficulties in swallowing, phonation, and mastication. Different treatments have been proposed for its resolution, some non-surgical and others surgical. Surgical procedures can be performed by dis- placing local or regional tissue or by grafting. The aim of this case report is to present clinical situations of oral sinus and oral nasal communication with different etiologies and their different treatments according to the size and location of the defect. Clinical cases: A group of patients who attended the Maxillofacial Surgery Service of Piñero Hospital presenting four acute and chronic oral sinus and one oronasal communi- cations were identified. The analyzed cases were treated sur- gically using different flaps according to the size and location of the defect (AU)

RESUMO

Abstract Objective: Continuous Positive Airway Pressure (CPAP) is the gold standard treatment for OSA. A wide variety of masks are used during CPAP therapy. The aim of the study is to compare polysomnography outcomes during titration for different types of masks (oronasal, nasal and pillow) and assess the impact on PAP titration. Methods: We retrospectively analyzed all CPAP titration polysomnography for one year. Anthropometric data and baseline apnea severity were documented. Results: A total of 497 patients were evaluated. Nasal masks were used in 82.3% (n = 409), pillow in 14.1% (n = 70) and oronasal in 3.6% (n = 18). There was no difference according to body mass index and baseline apnea-hypopnea index among the groups. The oronasal group was older and had higher titrated CPAP pressure, higher residual apnea-hypopnea index, lower sleep efficiency, more superficial N1 sleep and longer wake time after sleep onset. All other polysomnography outcomes were similar among the groups. The mean CPAP level was 11.6 ± 2.1 cm H2O for the oronasal mask, 10.1 ± 2.1 cm H2O for the nasal mask and 9.8 ± 2.2 cm H2O for the pillow. The residual apnea-hypopnea index was 10.4 ± 7.9 for the oronasal mask, 5.49 ± 5.34 events/h for the nasal mask and 4.98 ± 5.48 events/h for the pillow. The baseline apnea-hypopnea index was correlated with of a higher CPAP pressure for all the groups (p< 0.001 for the nasal group, p = 0.001 for the pillow group and p = 0.049 for the oronasal group). Body mass index and residual AHI were correlated with of a higher CPAP pressure for the nasal and pillow groups only (p < 0.001). Conclusion: The interface can have a significant impact on the effectiveness of PAP titration. Patients with oronasal masks have higher CPAP pressure, higher residual apnea-hypopnea index, lower sleep efficiency and higher wake time after sleep onset. Oronasal masks should not be recommended as the first choice for apnea patients. Level of evidence: Level 3.

RESUMO

Resumen El diagnóstico diferencial de las lesiones destructivas de la línea media es amplio y complejo debido a su presentación clínica poco específica, pudiendo abarcar desde cuadros infecciosos, neoplásicos y patologías autoinmunes. Una entidad a considerar son las lesiones destructivas de la línea media inducidas por cocaína (CIMDL), la que se caracteriza por una extensa destrucción de estructuras a nivel medio-facial. Se presenta el caso de un paciente con antecedentes de consumo de cocaína con una gran lesión destructiva endonasal asociada a una perforación palatal, fiebre, cervicalgia y meningismo. Se realizó un estudio nasofibroscópico y exámenes de laboratorio donde destaca un leve aumento de parámetros inflamatorios y serología positiva para anticuerpos anticitoplasma de neutrófilo (ANCA). Los exámenes imagenológicos destacan una trombosis de carótida interna derecha, osteítis del clivus y paquimeningitis retroclival. Se decide ingresar a pabellón para realizar un aseo y tomar biopsias. Al descartar los diagnósticos diferenciales de CIMDL, el paciente inició terapia antibiótica y antifúngica endovenosa evolucionando en forma satisfactoria. La CIMDL es una condición infrecuente cuyo principal diagnóstico diferencial es la granulomatosis con poliangeitis. Dada similitud en las presentaciones clínicas y la gran diferencia en el manejo de ambas patologías la necesidad de un diagnóstico certero es fundamental.

Abstract Differential diagnosis of destructive midline injuries is complex due to its nonspecific clinical presentation, and the broad variety of conditions that share the same signs and symptoms, such as infections, neoplasms and autoimmune diseases. One of the etiologies that should be considered is cocaine-induced destructive midline lesions (CIMDL), cha- racterized by extensive destruction of midface structures. The following case describes a patient with history of cocaine abuse with a large destructive endonasal lesion asso- ciated with a palatal perforation, fever, cervicalgia and meningism. Clinical assessment included a nasofibroscopy and laboratory tests. Results revealed a slight increase in in- flammatory parameters and positive antineutrophil cytoplasmic antibody serology. Ad- ditionally, imaging revealed a thrombosis of the right internal carotid, clivus osteitis, and retroclival pachymeningitis. Surgical debridement was performed, and biopsies of the nasal cavity were taken. Once the other possible diagnoses were ruled out, the patient was started on intravenous antibiotic and antifungal therapies. The patient showed a positive response to treatment and was successfully discharged after two months. CIMDL is a rare condition whose main differential diagnosis is granulomatosis with polyangiitis. Given the similarity in clinical presentations and the important differences in the management of both pathologies, the need for an accurate diagnosis is essential.

RESUMO

PURPOSE: Mask type (nasal versus oronasal) can affect the optimal pressure required to correct the apnea/hypopnea index (AHI) in obstructive sleep apnea (OSA) subjects treated with CPAP. Our objective was to evaluate if mask type influenced CPAP titration outcomes in OSA patients. METHODS: A retrospective study of individuals with a baseline AHI ≥ 15.0/h, who received an auto-adjusting CPAP titrating device (S9 AutoSet ResMed®) in a sleep-lab setting. The mask type oronasal (OM) or nasal (NM) was always selected by the patients. Optimal pressure requirements, leak, and residual AHI were compared based on mask type. RESULTS: Overall, 436 patients were included: 283 with NM (64.9%) and 153 with OM (35.1%). At baseline, NM and OM cohorts had similar AHI (p = 0.160). Patients allocated to the OM cohort had a higher 95th percentile pressure, a higher 95th percentile leak, and a higher residual AHI than those with a NM: pressure requirement: 12.9 cm H2O (IQR: 10.6-15.0) versus 10.7 cm H2O (IQR: 9.2-12.3); leak: 21.6 L/min (IQR: 9.6-37.2) versus 9.6 L/min (IQR: 3.6-19.2); and residual AHI: 4.9/h (IQR: 2.4-10.2) versus 2.2/h (IQR: 1.0-4.4), respectively (p < 0.001 for all). CONCLUSIONS: CPAP mask type based on individual preferences exerts profound effects on optimal CPAP pressures and efficacy. Patients titrated with OM showed higher pressure requirements, had higher a leak, and higher residual AHI when compared to NM, which may adversely impact treatment adherence and other health outcomes.

RESUMO

In subjects with neuromuscular diseases (NMD), the choice of facemask is essential for successful long-term noninvasive ventilation (NIV). While nasal masks usually represent the first line of treatment, almost a third of our subjects with NMD use an oro-nasal interface. Factors associated with the choice of mask remain poorly understood. We provide an original analysis of a previous prospective, multi-centric, Franco-Belgian survey investigating the factors associated with the type of nocturnal mask used in 116 adult NMD subjects treated with NIV. In these patients oro-nasal mask use was more often associated with non-Duchenne muscular dystrophy, older subjects, higher body mass index, better upper limb autonomy allowing independent mask removal and shorter periods of ventilation. Controlled prospective studies are needed to compare the efficacy and tolerance of different interfaces in this specific population.

RESUMO

PURPOSE: The present study evaluated the upper airway pattern of obstruction in individuals undergoing drug-induced sleep endoscopy (DISE) exam with positive airway pressure (PAP), and compared this effect through a nasal or oronasal mask. METHODS: Prospective study. Patients requiring PAP due to obstructive sleep apnea (OSA) were evaluated through DISE at three different moments: (1) a baseline condition (without PAP); (2) PAP treatment with a nasal mask; and (3) PAP with an oronasal mask at the same pressure. The conditions were compared intra-individually, following VOTE classification. A TOTAL VOTE score (the sum of VOTE scores observed for each anatomical site) was also applied to compare intra-individual results. RESULTS: Thirteen patients were enrolled in the study. All patients presented multi-level pharyngeal obstruction at baseline condition. In six patients, the pattern of obstruction differed according to the mask. Nasal mask significantly decreased the obstruction score when compared with baseline condition both in velum (P value < 0.05) and oropharynx regions (P value < 0.005). TOTAL VOTE score was also significantly lower during nasal mask evaluation when compared with basal condition (P value < 0.005). Remarkably, oronasal mask with the same pressure was not as effective as nasal masks. Obstruction levels observed at the tongue base or epiglottis levels were more resistant to PAP treatment. CONCLUSIONS: Collapse in velum and oropharyngeal sites is more compliant to PAP than obstruction at lower levels of the pharynx, either with nasal or oronasal masks. Nasal mask is superior to prevent pharyngeal collapse than oronasal devices under the same pressure.

RESUMO

Oronasal breathing may adversely impact obstructive sleep apnea (OSA) patients either by increasing upper airway collapsibility or by influencing continuous positive airway pressure (CPAP) treatment outcomes. Predicting a preferential breathing route would be helpful to guide CPAP interface prescription. We hypothesized that anthropometric measurements but not self-reported oronasal breathing are predictors of objectively measured oronasal breathing. Seventeen OSA patients and nine healthy subjects underwent overnight polysomnography with an oronasal mask with two sealed compartments attached to independent pneumotacographs. Subjects answered questionnaires about nasal symptoms and perceived breathing route. Oronasal breathing was more common (P = <0.001) among OSA patients than controls while awake (62 ± 44 vs. 5 ± 6%) and during sleep (59 ± 39 vs. 25 ± 21%, respectively). Oronasal breathing was associated with OSA severity (P = 0.009), age (P = 0.005), body mass index (P = 0.044), and neck circumference (P = 0.004). There was no agreement between objective measurement and self-reported breathing route among OSA patients while awake (κ = -0.12) and asleep (κ = -0.02). The breathing route remained unchanged after 92% of obstructive apneas. These results suggest that oronasal breathing is more common among OSA patients than controls during both wakefulness and sleep and is associated with OSA severity and anthropometric measures. Self-reporting is not a reliable predictor of oronasal breathing and should not be considered an indication for oronasal CPAP.NEW & NOTEWORTHY Continuous positive airway pressure (CPAP) interface choice for obstructive sleep apnea (OSA) patients is often guided by nasal symptoms and self-reported breathing route. We showed that oronasal breathing can be predicted by anthropometric measurements and OSA severity but not by self-reported oronasal breathing. Self-reported breathing and nasal symptoms should not be considered for CPAP interface choice.

RESUMO

BACKGROUND: An oronasal mask is frequently used to treat OSA. In contrast to nasal CPAP, the effectiveness of oronasal CPAP varies by unknown mechanisms. We hypothesized that oral breathing and pressure transmission through the mouth compromises oronasal CPAP efficacy. METHODS: Thirteen patients with OSA, well adapted to oronasal CPAP, were monitored by full polysomnography, pharyngeal pressure catheter, and nasoendoscope. Patients slept with low doses of midazolam, using an oronasal mask with sealed nasal and oral compartments. CPAP was titrated during administration by the oronasal and nasal routes, and was then reduced to induce stable flow limitation and abruptly switched to the alternate route. In addition, tape sealing the mouth was used to block pressure transmission to the oral cavity. RESULTS: Best titrated CPAP was significantly higher by the oronasal route rather than the nasal route (P = .005), and patients with > 25% oral breathing (n = 5) failed to achieve stable breathing during oronasal CPAP. During stable flow limitation, inspiratory peak flow was lower, driving pressure was higher, upper airway inspiratory resistance was higher, and retropalatal and retroglossal area were smaller by the oronasal rather than nasal route (P < .05 for all comparisons). Differences were observed even among patients with no oral flow and were abolished when tape sealing the mouth was used (n = 6). CONCLUSIONS: Oral breathing and transmission of positive pressure through the mouth compromise oronasal CPAP.

RESUMO

BACKGROUND: Nasal CPAP is the "gold standard" treatment for OSA. However, oronasal masks are frequently used in clinical practice. The aim of this study was to perform a meta-analysis of all randomized and nonrandomized trials that compared nasal vs oronasal masks on CPAP level, residual apnea-hypopnea index (AHI), and CPAP adherence to treat OSA. METHODS: The Cochrane Central Register of Controlled Trials, Medline, and Web of Science were searched for relevant studies in any language with the following terms: "sleep apnea" and "CPAP" or "sleep apnea" and "oronasal mask" or "OSA" and "oronasal CPAP" or "oronasal mask" and "adherence." Studies on CPAP treatment for OSA were included, based on the following criteria: (1) original article; (2) randomized or nonrandomized trials; and (3) comparison between nasal and oronasal CPAP including pressure level, and/or residual AHI, and/or CPAP adherence. RESULTS: We identified five randomized and eight nonrandomized trials (4,563 patients) that reported CPAP level and/or residual AHI and/or CPAP adherence. Overall, the random-effects meta-analysis revealed that as compared with nasal, oronasal masks were associated with a significantly higher CPAP level (Hedges' g, -0.59; 95% CI, -0.82 to -0.37; P < .001) (on average, +1.5 cm H2O), higher residual AHI (Hedges' g, -0.34; 95% CI, -0.52 to -0.17; P < .001) (+2.8 events/h), and a poorer adherence (Hedges' g, 0.50; 95% CI, 0.21-0.79; P = .001) (-48 min/night). CONCLUSIONS: Oronasal masks are associated with a higher CPAP level, higher residual AHI, and poorer adherence than nasal masks.

We report the case of a female patient of 24 years old from the city of Cajamarca referred to us, whom we evaluated, prepared and made a surgery with a tongue flap along the previous base, irrigated by the lingual artery in the Plastic Surgery and Burns Section at the Archbishop Loayza National Hospital to achieve the closing two stages (day 0 and then day 22 ) of a large oronasal fistula that caused rinofonía and nasal reflux of liquids and food; due to previous dehiscence Palatoplasty carried out in his city at the age of 2 years in a free foreign campaign of cleft lip and palate

RESUMO

BACKGROUND: CPAP is the gold standard treatment for OSA and was conceived to be applied through a nasal interface. This study was designed to determine the acute effects of changing the nasal CPAP route to oronasal and oral in upper airway patency during sleep in patients with OSA. We hypothesized that the oronasal route may compromise CPAP's effectiveness in treating OSA. METHODS: Eighteen patients (mean ± SD age, 44 ± 9 years; BMI, 33.8 ± 4.7 kg/m2; apnea-hypopnea index, 49.0 ± 39.1 events/hour) slept with a customized oronasal mask with nasal and oral sealed compartments connected to a multidirectional valve. Sleep was monitored by using full polysomnography and induced by low doses of midazolam. Nasal CPAP was titrated up to holding pressure. Flow route was acutely changed to the oronasal (n = 18) and oral route (n = 16) during sleep. Retroglossal area was continuously observed by using nasoendoscopy. RESULTS: Nasal CPAP (14.8 ± 4.1 cm H2O) was able to stabilize breathing in all patients. In contrast, CPAP delivered by the oronasal and oral routes promoted obstructive events in 12 (66.7%) and 14 (87.5%) patients, respectively. Compared with stable breathing during the nasal route, there was a significant and progressive reduction in the distance between the epiglottis and tongue base and the retroglossal area when CPAP was delivered by the oronasal and oral routes. CONCLUSIONS: CPAP delivered through the oronasal route may compromise CPAP's effectiveness in treating OSA.

RESUMO

Las fístulas oronasales son una de las secuelas más comunes consecutivas a la reparación quirúrgica del paladar hendido. El propósito de este reporte es presentar la experiencia con el uso de colgajos de lengua para el cierre de fístulas palatinas anteriores amplias (mayores de 1 cm) o con intentos quirúrgicos previos fallidos. El cierre de las fístulas palatinas anteriores mayores de 1 cm o con tratamientos previos sin éxito. Mediante colgajos de lengua es una de las opciones de tratamiento reportados en la literatura con un alto porcentaje de éxito. En este artículo presentamos un caso clínico de un paciente masculino de 23 años de edad con diagnóstico de secuelas labio y paladar hendido bilateral, que se presenta a la clínica de cirugía oral y maxilofacial de la división de estudios de postgrado e investigación, a la exploración intraoral presentaba una fístula palatina anterior de 2.5 cm de diámetro, con el antecedente de varios intentos quirúrgicos sin éxito, por lo que se decide realizar el cierre de la fístula palatina anterior con un colgajo de lengua de base anterior.

Oro-nasal fistulae are amongst the most common sequels after surgical repair procedures of cleft palate patients. The aim of the present study was to present the experience of using tongue flaps for closure of wide (over 1 cm) anterior palatal fistulae, or in those cases when surgery had previously failed. Closure with tongue flaps of anterior palatal fistulae larger than 1 cm, or when previous treatments have failed is one of the most successful treatment options reported in scientific literature. In the present article we introduce the case of a 23 year old male with bilateral cleft palate and lip surgery sequels. The patient attended the Maxillofacial and Oral Clinic of the Graduate and Research School. Intra-oral exploration revealed a 2.5 diameter anterior palatal fistula. The patient informed of a history of several failed surgical attempts; it was therefore decided to close the anterior palatal fistula with an anterior based tongue flap.

RESUMO

INTRODUÇÃO: Tradicionalmente, a fissura palatina é corrigida em duas camadas - uma camada mucosa nasal e camada muco-periosteal oral. Este estudo avaliou os resultados do fechamento em camada única de fissura palatina comparado ao fechamento tradicional em camada dupla. MÉTODOS: Trata se de revisão de prontuários de 101 casos de correção de fissura palatina realizados entre 1981 e 2012 em uma clínica assistencial/hospital terciário localizado no centro de Wisconsin. Os casos utilizaram fechamento em camada única e foram acompanhados em Clínica de Lábio Leporino por 12 meses. Foram incluídas fissura labial e palatina também como fissura palatina isolada. RESULTADOS: Todos os casos apresentaram cicatrização satisfatória exceto dois casos que necessitaram de correção posterior de pequena fistula. CONCLUSÃO: O fechamento em camada única de fissura palatina é tão efetivo quanto o fechamento tradicional em camada dupla, além disso apresenta mínimas complicações.

INTRODUCTION: Traditionally, cleft of the hard palate is repaired in two layers, with a nasal mucosal layer and an oral mucoperiosteal layer. The aim of this study was to evaluate the results of one layer closure of hard palate cleft compared to the traditional two layers closure. METHODS: The charts of 101 consecutive cases of repair of hard palate cleft performed by the authors from 1981 to 2012 at a tertiary care clinic/hospital in central Wisconsin were reviewed. The cases utilized the single layer closure and were followed in the Cleft Palate Clinic on a yearly basis. Cases included unilateral and bilateral cleft lip and palate as well as isolated cleft palate. RESULTS: All cases healed satisfactorily except for two cases that later required small fistulae repair. CONCLUSION: Single layer closure of the hard palate cleft is as effective as traditional two-layer closure, with minimal complications.

RESUMO

Este trabalho relata o caso de uma paciente felina que estava sendo tratada para rinite crônica há cerca de sete meses, sem apresentar qualquer recuperação. Ao exame físico foi constatada mobilida¬de do dente canino superior direito, associada a severo comprometimento periodontal. Após exame físico e radiológico, diagnosticou-se abscesso periapical e fístula oronasal, com drenagem tanto para a narina quanto para o saco conjuntival. O tratamento foi executado sob anestesia geral dissociativa, e incluiu exodontia do dente canino relacionado à fístula oronasal, e de diversos outros elementos dentais também severamente comprometidos. Adicionalmente realizou-se tratamento periodontal nos dentes remanescentes, e a paciente recebeu cuidados de enfermagem e medicação antibiótica e anti-inflamatória. O tratamento surtiu excelente efeito, e apesar de suas péssimas condições prévias, a evolução da paciente foi extremamente satisfatória, em curto espaço de tempo. Esse caso mostra a grande importância de um exame clínico odontológico completo e acurado, viabilizando diagnóstico adequado e tratamento apropriado. A demora em diagnosticar problemas dessa natureza e instituir precocemente o tratamento adequado, redunda em grande sofrimento e importante comprometimen¬to da qualidade de vida, especialmente em pacientes geriátricos(AU)

This paper reports the case of a feline patient treated for chronic rhinitis for seven months, without any results. The physical examination showed mobility and severe periodontal disease in the upper right canine tooth. After physical and radiographic evaluation the diagnosis was periapical abscess and oronasal fistula draining to the nare and the conjunctival sac. Treatment was performed under dissociative general anesthesia and included extraction of that canine tooth and other diseased teeth, as well as periodontal treatment for the remaining teeth. The patient also received antibiotic and an¬tinflamatory drugs, and pos-op nursing. The treatment was successful and even with its bad previous conditions; patient' s evolution was extremely satisfactory in a short period of time. This case shows the great importance of a complete and accurate physical examination, making possible the correct diagnostic and treatment. Delay in diagnosing this kind of problem and establish the appropriated treatment causes suffering and compromises the quality of life, especially in geriatric patients(AU)
