Tympanoplasty aims at rebuilding the tympanic membrane with or without middle ear functional recovery. Aim To evaluate the surgical results of tympanoplasties with a retro-auricular surgical approach at a medical residency unit. Materials and Methods Thirty-nine patients with diagnosis of simple chronic otitis media were evaluated; these patients underwent tymplanoplasty by a retro-auricular approach (underlay technique) at a medical residency unit. Patients were included in a prospective medical and audiologic investigation protocol that consisted of a clinical, otomicroscopic and audiometric evaluation. All procedures were supervised by training specialists otorrinolaringology. Results The rate of surgical success - full integration of the graft - was 95% of cases. Improvement of hearing, as demonstrated in audiometry, occurred in 72% of cases. Improvement in tinnitus was demonstrated subjectively on a visual analog scale in 69% of cases. Conclusion Tympanoplasty through a retro-auricular approach is easy to perform. Full graft integration occurred in 95% of cases and was independent of factors deemed by many authors as relevant. The results - improvement of the quality of hearing and tinnitus - were significant.

Introdução: A lesão coclear transitória ou permanente induzida por exposição à música de alta intensidade tem sido preocupação de diversos autores e motivo de vários estudos. Nesses trabalhos foram considerados de forma isolada os achados da audiometria tonal e as alterações às emissões otoacústicas (EOA), não tendo sido comparados os resultados dos dois exames. Forma de estudo: Prospectivo clínico não randomizado. Objetivo e Método: O objetivo do presente estudo é utilizar a audiometria associada às EOA para avaliação das alterações auditivas em 20 voluntários (40 orelhas), após exposição de 60 minutos ao walkman em alta intensidade, além de avaliar a prevalência de sintomas como hipoacusia, plenitude auricular e zumbido, observando-se o tempo que os mesmos perduraram. Conclusão: Os autores confirmam a presença de deslocamento limiar temporário (Temporary Threshold Shift - TTS) pós exposição ao walkman em alta intensidade, sendo as freqüências mais atingidas as de 4 KHz e 6 KHz.

sule is defined pathologically as a thick enveloping layer of connective tissue that is both microscopically and macroscopically evident, it must be concluded that ANs are nonencapsulated, at least in the conventional sense of the term. The surface peel observed intraoperatively is most likely surgically created during tumor debulking by cleaving the looser central component from the more compressed portion that lies immediately beneath the free margin of the lesion.
