Otosclerosis: An update on diagnosis and treatment

Batson, L. & Rizzolo, D. (2017) Journal of the American Academy of Physician Assistants. 30(2) pp. 17–22

Hearing loss affects the educational, psychological, and physical well-being of 360 million people worldwide. Otosclerosis, a process of progressive pathologic bone remodeling, is one of the more complex diseases that leads to hearing loss. In patients with otosclerosis, aberrant bone deposits surround and adhere to the ossicles, impairing the mechanical transmission of sound and leading to conductive hearing loss. In some patients with advanced disease, the lesions may extend into the bony labyrinth of the inner ear, affecting the cochlea and resulting in a mixed conductive and sensorineural hearing loss.

Objectives: Patients operated on for otosclerosis seem more often to complain about post-operative taste disturbance than those operated on for chronic otitis media, although the chorda tympani nerve more seldom becomes maltreated in stapedotomy. These observations seem paradoxical. It is unclear to what extent a post-operative taste disturbance affects the quality-of-life. This study aims to shed light on the occurrence of post-operative taste disturbances, on possible prognostic factors, and to what extent post-operative taste disturbance impairs the quality-of-life.

Conclusion: The incidence of taste disturbance after stapes surgery is high (61.9%), whereas the majority (94.8%) recovers within 1 year. More severe surgical nerve trauma caused more disturbance, implying that the nerve should be handled carefully during surgery.
