Quantification of Prosthesis Penetration With Conebeam in Otosclerosis — QUIPROCOS  

Otosclerosis Clinical Trial

Official title:
Early Postoperative Imaging of the Labyrinth by Cone Beam CT After Stapes Surgery for Otosclerosis With Correlation to Audiovestibular Outcome

Clinical Trial Summary

Sensorineural complications of stapes surgery are rare but potentially serious. Imaging is usually performed to identify an underlying cause, such as excessive intravestibular penetration of the prosthesis or pneumolabyrinth suggesting perilymphatic fistula.

Unfortunately, there is very little data in an unselected series of uneventful patients.

The aim of this study is to analyze the depth of prosthesis penetration within the vestibule and the rate of pneumolabyrinth the day or the day after the procedure by performing a Cone Beam CT (CBCT) of the temporal bone in a cohort of unselected patients, and to correlate imaging findings to clinical outcome. This prospective monocentric study is conducted in a tertiary referral medical center. A CBCT is performed in 80 consecutive patients having undergone stapes surgery for otosclerosis, the day or the day after the procedure. Penetration length and location of the prosthesis within the vestibule, as well as presence or absence of a pneumolabyrinth are recorded, and compared to clinical data (vertigo, nystagmus, hearing measurement).
