RESUMO

OBJECTIVES: Research trends concerning hearing loss within teen rural populations are limited and current evidence suggests that extended high-frequency audiometry can be a sensitive tool to detect subclinical hearing loss. Moreover, current research emphasises the importance of representing different ethnic populations in science. This study aimed to determine the prevalence of acquired hearing loss through conventional pure-tone (0.25-8 kHz) and extended high frequency (EHF) (9-20 kHz) audiometry in Afro-Colombian adolescents from a rural area in Colombia. DESIGN: Observational, cross-sectional study. PARTICIPANTS: 230 Afro-Colombian adolescents aged 13-17 years who attended high school in a rural population from Cartagena, Colombia. INTERVENTIONS: Otoscopic examination, conventional (0.25-8 kHz) and EHF (9-20 kHz) audiometry tests were performed during February-March 2021. Sociodemographic and associated factor questionnaires were also applied to assess probable factors associated with EHF hearing loss. MAIN OUTCOME MEASURES: Prevalence of acquired hearing loss using conventional and EHF audiometry, and factors associated with hearing loss. RESULTS: Of 230 adolescents who met the eligibility criteria, 133 (57.82%) were female. The mean age was 15.22 years (SD: 1.62). The prevalence of hearing loss in at least one ear assessed with conventional audiometry was 21.30% and with EHF audiometry 14.78%. The main abnormal otoscopic findings included: neotympanum (1.30%), myringosclerosis (0.87%) and monomeric scars (0.43%). Factors associated with a higher probability of EHF hearing loss found through logistic regression were older age (prevalence ratio (PR): 1.45; 95% CI 1.16 to 1.80), attending the 'Picó' four or more times a month (PR: 6.63; 95% CI 2.16 to 20.30), attending bars more than three times a month (PR: 1.14; 95% CI 1.03 to 1.59) and self-reported hearing difficulties (PR: 1.24; 95% CI 1.22 to 4.05). CONCLUSIONS: Our results suggest that acquired hearing loss is already widespread among this young rural population.

RESUMO

Introduction Unplanned hospital returns are frequent and may be preventable. Objective To comprehend the reasons for unplanned hospital readmission and return to the Outpatient Department (OPD) and Emergency Department (ED) within 60 days after discharge following head and neck surgery (HNS) at a tertiary care center in Saudi Arabia. Methods In the present retrospective study, the medical records of all patients who underwent HNS for benign and malignant conditions between January 2015 and June 2022 were reviewed in terms of demographic data, comorbidities, and reasons for hospital return. Results Out of 1,030 cases, 119 (11.55%) returned to the hospital within 60 days after discharge, 19 of which (1.84%) were readmitted. In total, 90 (8.74%) patients returned to the OPD, and 29 (2.82%), to the ED. The common reasons for readmission included infections (26.32%) and neurological symptoms (21.05%). For OPD visits, the common causes were hematoma (20%) and neurological symptoms (14.44%). For ED returns, the frequent causes were neurological symptoms (20.69%) and equipment issues (17.24%). Compared with nonreadmitted patients, readmitted patients had a higher preoperative baseline health burden when examined using the American Society of Anesthesiologists (ASA) score ( p = 0.004) and the Cumulative Illness Rating Scale (CIRS; p = 0.002). Conclusion The 60-day rates of unplanned hospital return to the OPD and ED were of 8.74% and 2.82% respectively, and 1.84% of the patients were readmitted. Hematoma, infections, and neurological symptoms were common causes. Addressing the common reasons may be beneficial to decrease postoperative hospital visits.

RESUMO

Havana Syndrome is used to describe the array of deficits seen in diplomats stationed in Cuba from August 2016 to September 2017.1 Patients from this cohort were clinically studied, investigating their symptoms, audition and vestibular deficits, and imaging abnormalities seen on MRI.1-3 The primary studies were retrospective, looking at how these symptoms could be classified or fit into diagnostic criteria. The cohort had many similarities: a sound at the onset of symptoms, a mix of neurologic and otologic symptoms, and persistent symptoms that lasted for months.1-3 Theories of the cause of Havana Syndrome have led to no conclusive answer. Potential viral etiologies, mass psychogenic illness, and head trauma were examined as causes.1-5 Diseases with established diagnostic criteria were used to compare the patients' symptoms to try to find a disease that fits Havana Syndrome.3 Recent information from the Office of the Director of National Intelligence suggested the most likely cause to be mass psychogenic illness. With the cause of Havana Syndrome still unknown, a review of reported cases and reports helps otolaryngologists understand Havana Syndrome so they diagnose it only when appropriate and do not miss other conditions that may present with similar symptoms and that might respond well to targeted treatment.

RESUMO

Introduction The outbreak of COVID-19 has produced an unprecedented number of trials and articles. Objective To study the impact of the COVID-19 pandemic on otolaryngology-head and neck surgery (ORL-HNS) journal processing times. Methods Original papers search of published in selected ORL-HNS journals in terms of times from submission-to-acceptance (S-A), acceptance-to-first online publication (A-P), and submission-to-online publication (S-P). Papers were divided into those published in the pre-COVID-19 era and those during the COVID-19 era. The latter were further divided into unrelated to COVID-19 and related to COVID-19. Results A total of 487 articles from 5 selected ORL-HNS journals were included, of which 236 (48.5%) were published during the pre-COVID-19 era and 251 (51.5%) were published during the COVID-19 era. Among them, 180 (37%) papers were not related to COVID-19, and 71 (14.5%) were related to COVID-19. The S-A duration of COVID-19-related articles was significantly shorter compared with that of papers submitted in the pre-COVID-19 era and to papers submitted in the COVID-19 era but unrelated to COVID-19 (median 6 to 34 days compared to 65 to 125 and 46 to 127, respectively) in all 5 journals. The most prominent reductions in S-A and S-P times were documented in the laryngology and otology/neurotology disciplines, respectively. Conclusions Processing times of the included papers were significantly shorter in most of the selected ORL-HNS journals during the COVID-19 era compared with the pre-COVID-19 era. COVID-19-related papers were processed more rapidly than non-COVID-19-related papers. These findings testify to the possibility of markedly expediting S-P times and hopefully set a precedent for postpandemic publishing schedules. Level Of Evidence: 5.

RESUMO

PURPOSE: This pilot cross-sectional study aimed to evaluate differences in electromyographic activity patterns of the masseter muscle according to the nasal patency in children with rhinitis and asthma. METHODS: The study included 43 children aged 5-14 years with rhinitis and/or asthma. Patients underwent peak nasal inspiratory flow (PNIF) measurement to assess nasal patency, and electromyographic evaluation of the right and left masseter muscles during chewing and at rest. Electromyographic activity patterns according to nasal patency were compared using the Mann-Whitney test, and effect sizes were measured using the Glass rank biserial (rb) correlation. A p-value of < 0.05 was considered statistically significant. RESULTS: No significant differences in electromyographic activity of the masseter muscle at rest, during unilateral chewing, or during habitual chewing were found between the groups. However, we found that patients with low nasal patency had a median electric activity of the right masseter muscle during maximum contraction of 60.53 (51.74-72.43), while those with adequate nasal patency had a median of 77.40 (56.71-88.45). Although the difference in myoelectric activity between the groups did not reach statistical significance (p = 0.061) at the adopted significance level of 5%, the size of the difference between groups were considered moderate (rb = 0.338) and a potential association between nasal patency and the muscular function of the masseter muscle could be suggested. CONCLUSION: The study found no differences in the electromyographic activity of the masseter muscle at rest, during unilateral chewing, or during habitual chewing among children with rhinitis and asthma based on nasal patency. Further research with larger sample sizes is needed to validate these findings and gain a better understanding of the impact of nasal patency on the muscular function of the masseter muscle.

RESUMO

INTRODUCTION: Obstructive sleep apnoea (OSA) is a common disorder that can affect the quality of life and increase the risk for psychiatric, neurological and cardiometabolic diseases. Despite the significant burden, it poses on health and well-being, there is a lack of evidence regarding the use of drug therapies in these patients. This work aims to evaluate the efficacy and safety of pharmacological treatment alternatives for patients with OSA. METHODS AND ANALYSIS: Databases, including PubMed, Embase, Web of Science, SciELO, LILACS, Scopus, Cochrane Register of Controlled Trials and ClinicalTrials.gov, will be used for the search. A search strategy was developed to retrieve clinical trials that have evaluated polysomnographic primary outcome (Apnoea-Hypopnoea index) and secondary outcomes (eg, daytime sleepiness, adverse events) of any drug therapy used for OSA. No date or language restrictions will be applied. Two authors will independently select the studies meeting the inclusion criteria by screening the title, abstract and full text. Data will be extracted, and the risk of bias will be evaluated using the Cochrane Risk of Bias Tool. Review Manager V.5.4.1 will be used for data synthesis. The Grading of Recommendation Assessment, Development and Evaluation will be used to assess the strength of the evidence. ETHICS AND DISSEMINATION: As a review of published data, it is not necessary to obtain ethical approval. The findings of this systematic review will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42022362639.

RESUMO

OBJECTIVE: The frequency of humanitarian surgical mission trips has grown over recent decades. Unfortunately, research on patient outcomes from these trips has not increased proportionately. We aim to analyze the safety and efficacy of surgeries in a low- and middle-income country missions-based surgery center in Guatemala City, Guatemala, and identify factors that influence surgical outcomes. STUDY DESIGN: Retrospective cohort study. SETTING: Guatemalan surgery center is called the Moore Center. METHODS: Pediatric patients underwent otolaryngology surgery between 2017 and 2019. All patients required follow up. We analyzed the effect of patient, surgical, and geographic factors on follow up and complications with univariate and multivariate analyses. RESULTS:  A total of 1094 otolaryngologic surgeries were performed between 2017 to 2019, which comprised 37.4% adenotonsillectomies, 26.8% cleft lip (CL)/cleft palate (CP) repairs, 13.6% otologic, and 20% "other" surgeries. Patients traveled on average 88 km to the center (±164 km). Eighty-nine percent attended their first follow up and 55% attended their second. The 11% who missed their first follow up lived farther from the center (p < .001) and had a higher ASA classification (p < .001) than the 89% who did attend. Sixty-nine (6.3%) patients had 1 or more complications. CL/CP surgery was associated with more complications than other procedures (p < .001). Of 416 tonsillectomies, 4 patients (1%) had a bleeding episode with 2 requiring reoperation. CONCLUSION: This surgical center models effective surgical care in low-resource areas. Complications and follow-up length vary by diagnosis. Areas to improve include retaining complex patients for follow up and reducing complications for CL/CP repair.

RESUMO

OBJECTIVE: Translate and cross-culturally adapt into Brazilian Portuguese the Glasgow Children's Benefit Inventory instrument used for the quality-of-life assessment after pediatric ENT interventions. METHOD: This is a methodological study of translation and cross-cultural adaptation of the GCBI instrument following seven stages: 1) Translation of two versions by two independent translators, 2) Elaboration of a consensual synthetized version, 3) Assessment of the synthetized version by experts, 4) Assessment by the target audience, 5) Back-translation, 6) Pilot study and 7) Use of the instrument. The final version of the instrument was answered by a sample of 28 people responsible for children aged from 2 to 7 years, submitted to tonsillectomy between January 2019 and December 2021, in a public hospital in Porto Alegre. The collection considered patients with a minimum of 6-months and a maximum of 3-years of postoperative follow-up. RESULT: The instrument final version was compared to the original version showing semantic equivalence, absence of consistent translation difficulties and appropriate cross-cultural adaptation, and well understood by the target audience. The application of the questionnaire in the sample showed a Cronbach alpha coefficient of 0.944 corresponding to a high degree of reliability of the instrument. CONCLUSION: The translation and cross-cultural adaptation showed semantic appropriateness and its use when assessing ENT postoperative results in a pediatric population showed high reliability of the instrument.

RESUMO

Introduction: Laryngopharyngeal reflux (LPR) manifests with a constellation of common throat symptoms and inconclusive signs on laryngoscopic exam. It is a diagnosis, often made clinically, that can lead to prescriptions of proton pump inhibitors that are unnecessary and potentially harmful. Glottic insufficiency (GI) and the accompanying hyperfunctional laryngeal behaviors can also present with similar, common throat complaints that may or may not include a qualitative change to the voice. Methods: This is a reflection article. It is written to summarize, explain, and support with evidence the opinion of the author on the topic of how symptoms of voice disorders can easily be mistaken for symptoms of LPR. The offered reflection is based on his experience, research and the available literature. Reflection: This article intends to explore the similarities between GI and LPR, how to ultimately differentiate them and how to approach treatment with a broader differential diagnosis. Conclusion: LPR and GI can present with identical, vague throat, and voice symptoms. Empiric medication trials, behavioral interventions and objective laryngovideostroboscopy, impedance-based reflux, and esophageal motility testing may all be needed, sometimes in a trial and error fashion, to correctly diagnose and treat a patient's symptoms.

Introducción: El reflujo laríngeo-faríngeo (LPR, por sus siglas en inglés) se manifiesta con una serie de síntomas comunes en la garganta y signos no concluyentes en el examen larinoscópico. Es un diagnóstico que a menudo se realiza clínicamente y que puede llevar a la prescripción de inhibidores de la bomba de protones que son innecesarios y potencialmente perjudiciales. La insuficiencia glótica (IG) y los comportamientos laríngeos hiperfuncionales que la acompañan también pueden presentar síntomas de garganta comunes similares, que pueden o no incluir un cambio cualitativo en la voz. Métodos: Este es un artículo de reflexión. Está escrito para resumir, explicar y respaldar con evidencia la opinión del autor sobre cómo los síntomas de los trastornos de la voz pueden confundirse fácilmente con los síntomas del LPR. La reflexión ofrecida se basa en su experiencia, investigación y la literatura disponible. Reflexión: Este artículo tiene la intención de explorar las similitudes entre la IG y el LPR, cómo diferenciarlos finalmente y cómo abordar el tratamiento con un diagnóstico diferencial más amplio. Conclusión: El LPR y la IG pueden presentar síntomas idénticos y vagos en la garganta y la voz. Puede ser necesario realizar ensayos de medicación empírica, intervenciones conductuales y pruebas objetivas de laringovideostroboscopia, reflujo basado en impedancia y motilidad esofágica, a veces de manera experimental, para diagnosticar y tratar correctamente los síntomas de un paciente.

RESUMO

Introduction Necrotizing otitis externa has a high impact on the quality of life of patients and has shown a significant increase in its incidence in recent years. There has been a change in the profile of affected patients and a lack of consensus on the management of these patients. Objective To develop a practical and effective care protocol to standardize the diagnostic and therapeutic management of necrotizing otitis externa. Methods A retrospective cohort study of necrotizing otitis externa patients between January 2015 and December 2020. Results There were 34 patients with two bilateral cases, totaling 36 ears. The mean age was 68.5, with a higher prevalence of males (76%). Diabetes was present in 97% of the samples. The involvement of cranial pairs was identified in 35% of the sample. Pseudomonas aeruginosa was the most frequent pathogen isolated, found in 50% of the cases. Among the cultures with bacterial agents isolated, 35% showed resistance to ciprofloxacin. The most frequent exam was computed tomography (94%). Hospital admission was indicated for 31 patients (91%), and ceftazidime was the most prescribed drug (35.5%). There were 11 recurrences (32%), and 12 patients (35%) had complications during treatment. Among the unfavorable outcomes, 12% persisted with some degree of peripheral facial paralysis, 6% maintained dysphagia, and 9% died of the disease. Conclusions The present study developed a diagnostic and therapeutic protocol for the effective management of necrotizing otitis externa. This protocol is a dynamic tool and should be revised and updated as new demands emerge during its implementation.

RESUMO

OBJECTIVES: Defining the laryngeal and vocal alterations in the pediatric group studied in private speech therapy facilities; and estimating the time period between the problem being identified by the parents and the access to the proper provided services. METHODS: A cross-sectional analytical observational research with data collected from medical records by the speech therapist of each private facility. A written form was prepared and sent to the speech therapists of the 40 existing facilities. We received 124 of them from the pediatric group being assisted in 15 of the facilities. The form included questions about gender, age, vocal complaints; general degree of dysphonia; otorhinolaryngological diagnosis of vocal fold alterations; the age that the problem was identified by the parents and the beginning of speech therapy. The larynx was examined by videonasopharyngolaryngoscopy, and voice quality by auditory-perceptual assessment. RESULTS: The time period between the identification of the participant's dysphonia by the parents and the start of speech therapy was considered long (3.5years). The group showed variance in the proportion of nodule and cyst between genders. The highest prevalence of nodules occurred in boys; and the cyst in girls. Moderate general dysphonia occurred between 4 and 17years old, average age of 7years and 7months, with greater distribution between 5 and 10years of age. CONCLUSIONS: The average time delay until the start of speech therapy was 3.5years, more frequently in the 5-10years group and due to nodules in boys and cysts in girls.

RESUMO

OBJECTIVES: To understand how primary language and interpreter use affect no-show rates in pediatric otolaryngology. METHODS: This is a retrospective cohort study using medical records of new patients in a pediatric otolaryngology clinic from 2014 to 2019. Data was collected on patient demographics including age, primary language, insurance type, maternal education level, maternal primary language, interpreter use at the first visit, total number of appointments scheduled, number of missed appointments, and number of completed appointments. Inferential statistics using parametric (ANOVA) and non-parametric (Mann-Whitney U tests, Kruskal-Wallis tests, and Spearman correlation coefficient) methods were used. RESULTS: Primary language was associated with significant differences in no-show rates (p = 0.0474), with Spanish and English speakers having the lowest no-show rate (33%). Overall, interpreter use at the first visit was not significantly associated with subsequent appointment attendance (p = 0.3674). Patients with a documented Spanish interpreter at the first visit had the lowest average no-show rate (31% ± 19%) compared to Haitian Creole (42% ± 18%) and all other languages (32% ± 19%) (p = 0.0265). Hispanic ethnicity, maternal education level, and maternal primary language were not associated with attendance. CONCLUSION: Interpreter use at the first visit was not significantly correlated with no-show rates, but among patients that did require an interpreter at the first visit, those receiving services in Spanish had the best clinic attendance.

RESUMO

Abstract Introduction In patients with chronic rhinosinusitis, conservative interventions with extended medical trials are often attempted prior to procedural treatment. Balloon sinuplasty (BSP) is an established procedure for symptomatic relief from chronic rhinosinusitis. However, data suggesting the suboptimal efficacy of prolonged medication management trials, prior to BSP, is lacking. Objectives The purpose of this study was to evaluate the efficacy of prolonged medication management trials, prior to BSP, for patients with chronic rhinosinusitis. Methods A retrospective review was performed for all adults with chronic rhinosinusitis who received extended medical management prior to their BSP at two outpatient clinics, from November 1, 2013, to June 31, 2018. The patients' Sino-Nasal Outcome Test (SNOT) scores were compared between baseline, post-medication trials, and post-BSP. Results The SNOT scores of a total of 64 patients were collected. Overall, patients showed a significant worsening of symptoms during the medication management trials from baseline (p = 0.002126) but significant improvement of symptoms after undergoing BSP (p < 0.0001). Conclusions The patient symptom burden worsened and prolonged during medication management trials. The BSP procedure alone showed significant improvement in the quality of life for chronic rhinosinusitis patients, when considering their SNOT scores. The worsening of patients' symptoms during medication management may invalidate the necessity of prolonged medication management trials.

RESUMO

Introducción: La patología otorrinolaringológica (ORL) presenta alta incidencia en atención primaria, alcanzando hasta 49% de las consultas, sin embargo, la pandemia por SARS-CoV-2 repercutió de manera transversal en los servicios sanitarios, pudiendo haber influido en el perfil de consulta, por lo que se requiere un análisis para la elaboración de estrategias que permitan asegurar la atención sanitaria ante eventos de esta magnitud. Objetivo: Analizar el perfil de consulta libre por patología ORL ambulatoria en un centro médico privado en La Serena durante los años 2019 y 2020. Material y Método: Estudio analítico de corte transversal sobre consultas ambulatorias durante los años 2019 y 2020 realizadas en un centro privado de atención abierta en La Serena. Se estimaron frecuencias en números absolutos y proporciones, estimación de promedios y medianas. Resultados: Durante 2019 hubo un total de 11.932 consultas y en 2020 hubo 9.576. Se observó un predominio de sexo femenino en las consultas de 51% en ambos años. La mediana en 2019 fue de 35 años y en 2020 de 39 años. En 2020 las patologías con mayor consulta fueron nariz (44%), oído (37%) y faringolaringe (14%). Existió un aumento significativo en la consulta por patología cocleovestibular durante 2020. Conclusión: En 2020 hubo una disminución del 19,7% de las consultas dado, probablemente, a las restricciones de movilidad y aforos. Existió un aumento significativo en la proporción de consultas por patologías cocleovestibulares, como vértigo periférico, hipoacusia súbita y tinnitus, atribuido probablemente al estrés emocional generado por la pandemia.

Introduction: Otolaryngological (ENT) pathology presents high incidence in primary care reaching up to 49% of morbidity consultations, however, the pandemic by SARS-CoV-2 had a transversal impact on health services, and may have influenced the consultation profile, so an analysis is required for the development of strategies to ensure health care in the face of events of this magnitude. Aim: To analyze the profile of spontaneous consultation for outpatient ENT pathology in a medical center in La Serena city during 2019 and 2020. Material and Methods: Cross-sectional analytical study of outpatient consultations during the years 2019 and 2020 performed in a private open care center in the commune of La Serena. Frequencies were estimated in absolute numbers and proportions; averages and medians were estimated. Results: During 2019 there were a total of 11,932 consultations and in 2020 there were 9,576. There was a predominance of female sex in the consultations of 51%. The median in 2019 was 35 years and in 2020 it was 39 years. In 2020, the pathologies with the highest number of consultations were nose (44%), ear (37%) and laryngopharynx (14%). There was an increase in consultation for cochleovestibular pathology during 2020. Conclusion: In 2020 there was a 19.7% of consultation decrease probably due to mobility and capacity restrictions. There was a significant increase in the proportion of consultations for cochleovestibular pathologies such as peripheral vertigo, hearing loss and tinnitus, probably attributed to the emotional stress generated by the pandemic.

RESUMO

Introduction: Laryngeal clefts (LC) are upper respiratory malformations predominately found in the posterior laryngeal wall. The frequency is 1:10,000, more frequently affect males, and can be syndromic features. There is no report of a transfixing anterior laryngeal cleft. Case report: This diabetic mother at full-term pregnancy delivered a stillborn macrosomic 4780 g dysmorphic stillborn male with left renal agenesis, aortic coarctation, and anterior laryngeal cleft. Conclusion: Anterior laryngeal clefts can occur, and in this case, occurred in association with renal agenesis and maternal diabetes.

RESUMO

PURPOSE: To relate the creation and expert validation (face and content validity) of an affordable three-dimensional (3-D) printed model of temporal bones with chronic otitis media with cholesteatoma (COMC) as a simulator for mastoidectomy. METHODS: We performed computed tomography (CT) of the temporal bones of a patient with COMC followed at the University of São Paulo (USP) Hospital with 3-D Slicer to create a 3-D model of the affected bone using light-curing resin and silicone (cholesteatoma). The final 3-D printed images were scored by 10 otologists using a customized version of the Michigan Standard Simulation Scale Experience (MiSSES). Internal consistency and inter-rater reliability were assessed using Cronbach's α and intraclass correlations. RESULTS: Otologists consistently scored the model positively for fidelity, educational value, reactions, and the overall model quality. Nine otologists agreed that the model was a good educational device for surgical training of COMC. All experts deemed the model ready-or nearly ready-for use. The final cost of the model, including raw materials and manufacturing, was 120 USD. CONCLUSIONS: Using 3-D printing technology, we created the first anatomically accurate, low-cost, disease-reproducing 3-D model of temporal bones for mastoidectomy training for cholesteatoma.

RESUMO

ABSTRACT Introduction: competency-based medical education is well established, but there is a worldwide shortage of instruments capable of assessing these doctors in training. Objective: to validate the instrument The Otolaryngology - Head and Neck Surgery Milestone Project for use in Residency Programs in Otorhinolaryngology in Brazil. Method: The study had 5 stages. In stage I, two independent translations of the Milestones Project in otorhinolaryngology were carried out. In step II, a synthesis of the translations was performed. Subsequently, the competencies required by the Brazilian Association of Otorhinolaryngology for training otorhinolaryngologists in Brazil were added. In step III, a back-translation of the instrument was carried out and sent to the original authors. Then, the instrument was sent to be evaluated by a committee of 8 experts. In stage IV, each expert made comments about each of the items, and after analyzing the suggestions, a new instrument was created. In stage V, this instrument was sent for evaluation by otorhinolaryngologists across the country. Results: after translations and expert evaluation, an instrument with 19 items was created. The instrument was submitted to analysis by Otorhinolaryngologists from all over Brazil. Acceptance percentages were: applicability (99.25%), reliability (99.5%), reproducibility (98.6%), reliability (93.84%), relevance (93.15%). Conclusion: the created instrument was considered applicable, reproducible, relevant, reliable and trustworthy, presenting content validity.

RESUMO Introdução: a formação médica baseada em competências é bem estabelecida, mas há uma escassez mundial de instrumentos capazes de avaliar esses médicos em formação.

Na etapa I foram realizadas duas traduções independentes do Projeto Milestones em otorrinolaringologia. Na etapa II, foi realizada uma síntese das traduções. Posteriormente foram acrescentadas as competências que a Associação Brasileira de Otorrinolaringologia exige para formação do otorrinolaringologista no Brasil. Na etapa III foi realizada uma retro tradução do instrumento e enviado para os autores originais. Em seguida, o instrumento foi enviado para ser avaliado por um comitê com 8 experts. Na etapa IV, cada expert fez comentários acerca de cada um dos itens, e após análise das sugestões foi criado um novo instrumento. Na etapa V, este instrumento foi enviado para apreciação de otorrinolaringologistas de todo o país. Resultados: após as traduções e apreciação dos experts foi criado um instrumento com 19 itens. O instrumento foi submetido à análise de Otorrinolaringologistas de todo Brasil. As percentagens de aceitação foram: aplicabilidade (99,25%), fidedignidade (99,5%), reprodutibilidade (98,6%), confiabilidade (93,84%), relevância (93,15%). Conclusão: o instrumento criado foi considerado aplicável, reprodutível, relevante, confiável e fidedigno, apresentando validade de conteúdo.
