OBJECTIVE The goal of the present study was to investigate the clinical utility of measurements of ear-canal reflectance (ECR) in a population of patients with conductive hearing loss in the presence of an intact, healthy tympanic membrane and an aerated middle ear. We also sought to compare the diagnostic accuracy of umbo velocity (VU) measurements and measurements of ECR in the same group of ...

OBJECTIVE Ossicular chain disruption in children leads to conductive hearing loss. Few studies have focused on factors influencing successful results in pediatric ossicular chain reconstruction (OCR). We aim to determine whether demographic or surgical factors affect hearing outcomes in pediatric OCR. METHODS We conducted a retrospective chart review of 120 patients undergoing OCR at our inst...

INTRODUCTION In children, hypoacusis, or conductive hearing loss, is usually acquired; otitis media with effusion is the most common etiology. However, in some cases this condition is congenital, ranging from deformities of the external and middle ear to isolated ossicular chain malformations. The non-ossicular anomalies of the middle ear, for instance, persistent stapedial artery and anomaly o...

INTRODUCTION Conductive hearing loss, in the presence of a normal external ear, is usually due to an interference with the normal transmission of sound from the tympanic membrane across the ossicular chain to the oval window. If conductive hearing loss occurs in a young child, congenital middle ear pathology is the most likely cause. MATERIALS AND METHODS High resolution computed tomography o...

OBJECTIVE To describe the audiometric results after stapes surgery in a consecutive series of patients with stapes footplate ankylosis combined with another ossicular middle ear anomaly. STUDY DESIGN A retrospective analysis of charts collected between 1986 and 2001. SETTING A tertiary referral center. PATIENTS A total of 25 patients (30 ears) underwent exploratory tympanotomies and ossic...

INTRODUCTION Otosclerosis is a disease of bony labyrinth. Structural changes in the labyrinth often cause ossicular fixation, and thus conductive hearing loss. The purpose of this study was to evaluate middle ear exploration findings and frequency of ossicular and footplate area anomalies in patients with suspected otosclerosis referred to Amiralmomenin and Golsar Hospitals in Rasht, Iran. MA...

OBJECTIVE To develop a staging system for congenital cholesteatoma in predicting the likelihood of residual disease. DESIGN Retrospective analysis of data from a case series, to identify predictors of residual disease. SETTING Tertiary care pediatric hospital. PARTICIPANTS Children undergoing surgical removal of congenital cholesteatoma. There were 156 patients, with 160 cholesteatomas; 4...

BACKGROUND We aimed to evaluate the clinical and imaging presentations of Langerhans cell histiocytosis (LCH) in the pediatric temporal bone. METHODS This retrospective study included 27 pediatric cases with pathological confirmed LCH of the temporal bone. The clinical and imaging features of the cases were analyzed. The involvement of ossicular chain and otic capsule was also evaluated. RE...
