To ascertain the usefulness of Mongolian gerbils as an inbred model for otitis media, 52 Mongolian gerbils (Meriones unguiculatus, strain MONT/Tum) were compared with 26 chinchillas (Chinchilla laniger) for susceptibility to Streptococcus pneumoniae type 3. Haemophilus influenzae type b, and a polymicrobic culture including anaerobes (Streptococcus intermedius, Propionibacterium acnes, Staphylo...

RATIONALE Tick infestation of the external auditory canal (EAC) constitutes <1% of all patients presenting with ear complaints. Consequently, parameters for the diagnosis and management of ticks in the EAC have not been established. PATIENT CONCERNS We report 2 cases of EAC infestation by Amblyomma testudinarium in 2 female patients, aged 12- and 72 years old. DIAGNOSES INTERVENTIONS AND OU...

Cholesteatoma is an expansive tissular process, non-neoplastic, well demarcated, developed in the temporal bone, with destructive effect. Cholesteatoma is diagnosed based on clinical, otoscopic examinations, sectional imaging examinations (computerized tomography in high resolution -HRCT and magnetic resonance imaging-MRI). Examination HRCT on the temporal bone is an exam with high sensitivity,...

We reported a rare case of ear trauma with delayed facial paralysis, ossicular chain dislocation and perilymph fistula caused by an earpick. A 36-year-old male consulted our clinic with a complaint of left otalgia, hearing loss, tinnitus and dizziness after left ear trauma with an earpick. Otoscopic examination showed perforation of the left ear-drum and pure tone audiometory demonstrated a mix...

Objective. This study aims to identify factors that may help predict recurrence, the need for second-look operations, and other outcomes in the pediatric population. Study Design. Case series with chart review. Setting. Tertiary medical center. Subjects and Methods. Five hundred and seventeen ears in 493 patients underwent primary acquired cholesteatoma resection over a 37-year period. Demograp...

There are no recent population-based data on the prevalence of hearing loss in older adults using standard audiometric testing. The population-based Epidemiology of Hearing Loss Study was designed to measure the prevalence of hearing loss in adults aged 48-92 years, residing in Beaver Dam, Wisconsin. Hearing thresholds were measured with standardized protocols using pure-tone air- and bone-cond...

Correspondence/Findings A common clinical definition of a chronic tympanic membrane perforation (TMP) is a perforation, which is still open after 3 months. Why the healing of a chronic TMP is arrested is still an enigma. Attempts to generate an animal model for studying the healing pattern of a chronic TMP have until recently been disappointing. However, several studies by the Umeå group, Ny T,...

Materials and Methods: This retrospective study was performed on 26 patients with acromegaly and 27 age-matched healthy controls. Otoscopic examination, pure tone odiometry, tympanometry, otoacoustic emissions, and stapes reflex were performed in all cases. Hearing thresholds of air and bone conduction (AC and BC), middle ear function, cochlear function, tympanic membrane compliance, gradient, ...

Introduction: Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by exploratory surgery. The need for imaging in an uncomplicated case is contentious. The study assesses the usefulness of a pre-operative high-resolution computed tomography (HRCT) in depicting the status of middle ear structures in the presence of cholesteatoma. Aim: The aim of this study is to evaluat...

A 37-year-old female was admittedwith bilateral hearing loss since her childhood. On examination of the case with no other complaint, the EACs were short and closed conically. There was a conductive type of hearing loss at 50 dB in the right ear (air bone gap 40 dB) , and at 47 dB (air bone gap 37dB) in the left ear on the pure tone audiogram. On temporal bone CT, bilateral the EACs were observ...
