The Audiology of Otosclerosis

Otolaryngol Clin North Am. 2018 Apr;51(2):327-342. doi: 10.1016/j.otc.2017.11.007. Epub 2018 Feb 2.


Diagnostic audiologic procedures for otosclerosis are effective tools in identifying this condition. Audiometric data usually demonstrate a conductive hearing loss at the early stages of otosclerosis. Modern middle ear analysis procedures are becoming more popular in the better diagnosis of otosclerosis. In clinical practice, cochlear otosclerosis can also be observed. Audiologic rehabilitation of otosclerosis includes fitting of hearing aids and implantable hearing devices. Current hearing technology enables patients who do not pursue surgical correction to function well and significantly improve their communication and quality of life. Otosclerosis may also be associated with annoying tinnitus, and tinnitus management is important in the rehabilitation process.
