Labyrinthine fistula by cholesteatoma surgery

Objectives To determine the feasibility of canal wall down cholesteatoma surgery with mastoid cavity obliteration for lesions involving the labyrinth, and validate a technique for this kind of lesions that increases the possibility of preserving the labyrinth and cochlea.

Study Design Observational study.

Setting Tertiary Referral center.

Cases 13 patients who underwent canal wall down cholesteatoma surgery with mastoid cavity obliteration for lateral skull base pathology involving the labyrinth from June 2014 to September 2018 were reviewed.

Interventions Clinical data of the 13 patients were collected.

Main Outcomes Measures: Presence of vertigo, hearing level and cholesteatoma recurrence.

Results Complete excision with labyrinth and cochlea preservation was achieved in all 176 cholesteatoma patients. 13 from them has labyrinthine fistula of lateral semicircular canal (7.39 %). These patients had preoperative mixed hearing loss and preoperative fistula symptom. After an average follow-up of 11.4 months (CD 13.1 months) no patient had cholesteatoma recurrence.

Conclusions Canal wall down cholesteatoma surgery with mastoid cavity obliteration is feasible for lesions involving the labyrinth and increases the likelihood to preserve the structure and function of labyrinth and cochlea.
