Ossicular chain reconstruction in chronic otitis media: hearing results and analysis of prognostic factors / Reconstrução da cadeia ossicular na otite média crônica: resultados auditivos e análise de fatores prognósticos

Abstract Introduction The goal of ossiculoplasty is to improve hearing and the success of this procedure depends on several factors. Objective Analyze the hearing results in patients with chronic otitis media undergoing ossicular chain reconstruction, as well as predictive factors for successful surgery. Methods Charts of patients undergoing ossiculoplasty between 2006 and 2016 were reviewed. Sixty-eight patients were included, totaling 72 ears. The following data was analyzed: gender, age, smoking status, laterality, pathology, audiometric exams, type of surgery, previous surgery, characteristics of the middle ear, otorrhea and ossicular chain status. Patients were also classified according to two indices: middle ear risk index and ossiculoplasty outcome parameter staging. The results were evaluated by comparing the air-bone gap before and after surgery. The success of reconstruction was defined as air-bone gap ≤20 dB and the improvement of speech reception Thresholds, calculated through the mean frequencies 0.5, 1, 2 and 3 kHz. Results Reconstruction success rate was 61%. The mean preoperative air bone gap was 34.63 dB and decreased to 17.26 dB after surgery. There was a correlation between low risk in middle ear risk index and ossiculoplasty outcome parameter staging indices with postoperative success. The most frequently eroded ossicle was the incus and the type of prosthesis most used was tragal cartilage. In the patients without incus, we achieved success in 74.2% of the surgeries. In the absence of the stapes, the success rate decreased to 63.3%. In the absence of the malleus, 85% of the patients had and air bone gap ≤20 dB. Conclusion We achieved good audiometric outcomes in ossiculoplasty and the results are comparable to other centers. Ossicle status influenced postoperative results, especially in the presence of stapes. We also concluded that the indexes analyzed may help to predict the success of the surgery.

Resumo Introdução A ossiculoplastia tem como objetivo a melhoria da audição e o sucesso desse procedimento depende de diversos fatores. Objetivo Analisar os resultados auditivos em pacientes com otite média crônica submetidos a reconstrução da cadeia ossicular, bem como os fatores preditivos de sucesso cirúrgico. Método Prontuários de pacientes submetidos a ossiculoplastia entre 2006 e 2016 foram revistos. Sessenta e oito pacientes foram incluídos, total de 72 orelhas. Os seguintes dados foram analisados: sexo, idade, tabagismo, lateralidade, doença, exames audiométricos, tipo de cirurgia, cirurgia prévia, características da orelha média, otorreia e estado da cadeia ossicular. Os pacientes também foram classificados de acordo com dois índices: índice de risco da orelha média e estadiamento do parâmetro de desfecho da ossiculoplastia. Os resultados foram avaliados comparando o gap aéreo-ósseo antes e após a cirurgia. O sucesso da reconstrução foi definido como gap aéreo-ósseo ≤ 20 dB e a melhoria dos limiares de recepção de fala, calculados pelas frequências médias de 0,5, 1, 2 e 3 kHz. Resultados A taxa de sucesso da reconstrução foi de 61%. O gap aéreo-ósseo pré-operatório médio foi de 34,63 dB e diminuiu para 17,26 dB após a cirurgia. Houve correlação entre baixo risco no índice de risco para orelha média e os índices de estadiamento do parâmetro de desfecho da ossiculoplastia com sucesso pós-operatório. O ossículo com erosão mais frequente foi a bigorna e o tipo de prótese mais utilizada foi a cartilagem tragal. Nos pacientes sem bigorna o sucesso foi alcançado em 74,2% das cirurgias. Na ausência do estribo, a taxa de sucesso diminuiu para 63,3%. Na ausência do martelo, 85% dos pacientes apresentaram gap aéreo-ósseo ≤ 20 dB. Conclusão Melhora significativa da audição foi observada em pacientes submetidos à ossiculoplastia, os resultados foram comparáveis aos de outros centros. O "status" dos ossículos influenciou os resultados pós-operatórios, principalmente a presença do estribo. Também concluímos que os índices analisados podem ajudar a prever o sucesso da cirurgia.

Avaliação da recidiva de sintomas obstrutivos após adenoidectomia e adenoamigdalectomia / Evaluation of obstructive symptoms relapse after adenoidectomy and adenotonsillectomy

A Síndrome da Apneia Obstrutiva do Sono (SAOS) na criança é uma doença que leva a alterações nos padrões arquiteturais do sono e apresenta como principais consequências o ronco habitual, dificuldades respiratórias, sonolência diurna, alterações neurocognitivas e prejuízo no ganho de peso e altura. Sua principal causa é a hipertrofia adenotonsilar e o tratamento mais efetivo é a adenoamigdalectomia. Apesar disso, estima-se que 9 a 29% das crianças não melhoram com a cirurgia. Sendo assim, objetivo deste estudo é avaliar crianças submetidas a tonsilectomia que persistem com prejuízo na qualidade de vida devido a SAOS e estabelecer as possíveis causas para essa recidiva ou persistência dos sintomas. Trata-se de um estudo analítico transversal, que avaliou 99 crianças em um momento, dois anos após adenoidectomia/adenoamigdalectomia. Foram estudados: queixa do familiar relacionada a sintomas obstrutivos, rinite, asma, tabagismo passivo, enurese, características anatômicas desfavoráveis, hipertrofia de cornetos inferiores, desvio de septo nasal obstrutivo, palato mole redundante, hipertrofia amigdaliana, Mallampatti e hipertrofia adenoideana. Os pacientes foram separados em 2 grupos conforme o questionário OSA-18, sendo um com pontuação maior ou igual a 60 (grupo teste) e outro com pontuação menor que 60 (grupo controle). Realizada regressão logística binária, chegou-se à conclusão de que a queixa do familiar, a enurese e a hipertrofia de cornetos apresentam relação estatisticamente positiva com prejuízos na qualidade de vida relacionada à SAOS.

Obstructive Sleep Apnea Syndrome (OSAS) in children is a disease that leads to alterations in the architectural patterns of sleep and presents as main consequences habitual snoring, breathing difficulties, daytime sleepiness, neurocognitive alterations and impairment in weight gain and height. Its main cause is adenotonsillar hypertrophy and the most effective treatment is adenotonsillectomy. Despite this, it is estimated that 9 to 29% of children do not improve with surgery. Therefore, the objective of this study is to evaluate children submitted to tonsillectomy who persist with impaired quality of life due to OSAS and establish the possible causes for this relapse or persistence of symptoms. It is a cross-sectional analytical study that evaluated 99 children at one time two years after adenoidectomy / adenotonsillectomy. The following were studied: family complaint related to obstructive symptoms, rhinitis, asthma, passive smoking, enuresis, unfavorable anatomical characteristics, inferior turbinate hypertrophy, obstructive nasal septum deviation, redundant soft palate, tonsils hypertrophy, Mallampatti and adenoidean hypertrophy. Patients were separated into 2 groups according to the OSA-18 questionnaire, one with a score greater than or equal to 60 (test group) and another with a score lower than 60 (control group). A binary logistic regression was performed, and the family complaint, enuresis and turbinate hypertrophy were statistically positive with losses in OSAS-related quality of life.

Bilateral Peritonsillar Abscess in an Infant: An Unusual Presentation of Sore Throat.

INTRODUCTION: Peritonsillar abscess is considered a suppurative complication of acute tonsillitis. It is usually unilateral and clinically evident bilateral presentation is uncommon. The condition affects mainly children older than 10 years and young adults. Herein we present a rare case of bilateral peritonsillar abscess in an infant. PRESENTATION OF CASE: A 1-year-old boy presented with a two-day history of worsening sore throat, loss of appetite, vomiting, and fever. Examination of the oral cavity and oropharynx revealed enlarged and inflamed tonsils and a bilaterally congested and bulging soft palate. CT scan confirmed the hypothesis of bilateral peritonsillar abscess. Antibiotic therapy was instituted and after 5 days only slight regression of swelling of the soft palate was observed. He underwent a surgical procedure for draining the abscesses. After the procedure, he presented good clinical and laboratory evolution and was discharged home. DISCUSSION: Although peritonsillar abscesses are considered common complications of acute tonsillitis bilateral cases are extremely rare, especially in early childhood. The diagnosis is based on history and physical examination and the treatment remains controversial among otolaryngologists. CONCLUSION: Bilateral peritonsillar abscess should be diagnosed and treated promptly and adequately to prevent respiratory obstruction and to avoid dissemination into the deep neck spaces.

Laparoscopic nephrectomy with single-portal access Gelpoint®in swines.

PURPOSE: To analyze the viability of using Gelpoint® (single-port access) to make partial and total nephrectomy in pigs and to describe the technical difficulties found during these surgical procedures. METHODS: Ten pigs (Landrace specie) with 20 kg in average were distributed in two groups. Group A: total right nephrectomy and Group B: partial left nephrectomy. The procedures were performed inside the Surgical Technique Room from Pontifícia Universidade Católica do Parana (PUCPR). RESULTS: In Group A, time to single-port insertion varied from one to two minutes and total time of the procedures were 20.4 ± 8.2 minutes. Bleeding was under than 20 mL in 70% of animals. Time of instrument excision was 20.7 ± 12 seconds and time of hilum dissection was 3.9 ± 2.2 minutes. In Group B, after total contralateral nephrectomy two surgical procedures were not concluded due to bleeding. In this group, time of surgery was 6.8 ± 4.2 minutes. With the exception of the second surgery, the highest blood volume loss was 50 mL. The mean excision time was 22.3 ± 22.3 seconds. CONCLUSION: Total and partial nephrectomy through umbilical single-access using GelPoint® was feasible and safe in pigs.
