Aim: Otosclerosis is an autosomal dominant disease with variable penetrance and expression. It is characterized by dystrophy of enchondral layer of otic capsule. Otosclerosis typically presents with conductive hearing loss and intact tympanic membrane. Sensorineural or mixed hearing loss may be present in some cases.
Methods and results: Otosclerosis is categorized into two major groups, fenestral and retrofenestral (cochlear). The diagnosis of otosclerosis is based on history, series of audiologic tests and imaging modalities. HRCT is imaging modality of choice. HRCT helps to establish diagnosis of otosclerosis, excludes other cause of conductive hearing loss with intact tympanic membrane and allows grading of otosclerosis.
Conclusion: The size and localisation of otosclerotic labyrinth impairment imaged by HRCT in corelation with level of hearing in diagnosis is the aim of this study.
