Background and Objectives Wideband tympanometry (WBT) provides information additional to what can be provided by the relms of traditional tympanometry, such as absorbance, resonance frequency, peak pressure. We investigated characteristics WBT in various middle ear disorders, especially for chronic otitis media (COM), otosclerosis, patulous eustachian-tube disorder (ETD). Subjects Method recrui...

Malformations of bony inner ear are rare anomalies occurring in approximately 20% of patients with congenital sensorineural hearing loss. Conductive hearing loss is usually associated with abnormalities of the external and middle ear. Recent reports of patients with lateral semicircular canal malformations indicate inner ear malformations to be associated with sensorineural or conductive hearin...

Otosclerosis is a relatively common heterogenous condition, characterized by abnormal bone remodelling in the otic capsule leading to fixation of the stapedial footplate and an associated conductive hearing loss. Although familial linkage and candidate gene association studies have been performed in recent years, little progress has been made in identifying disease-causing genes. Here, we used ...

Introduction: Stapedectomy is now one of the most popular and common surgeries done worldwide. Otosclerosis remains the most common single cause of conducting hearing loss in adult population. Females are more frequently affected than males with an approximate 2:1 ratio. Materials and Methods: This study consists of 94 patients who underwent stapedectomy for otosclerosis. This study was conduct...
