ABSTRACT
OBJECTIVES/HYPOTHESIS:
To demonstrate imaging of labyrinthine fistula due to cholesteatoma and illustrate outcome following repair with bone pate. STUDYDESIGN:
Retrospective review.METHODS:
Patients with labyrinthine fistula due to cholesteatoma were identified, and pre- and postoperative imaging was assessed. Method of repair was recorded. The fistula site was examined for patency and bone density after repair.RESULTS:
Twenty-nine fistulae were seen in a cohort of 375 cholesteatoma cases (8%). Preoperative computed tomography (CT) imaging for fistula detection showed sensitivity of 96% and specificity of 90%. The lateral semicircular canal was the most common site of dehiscence occurring in all cases. Facial nerve dehiscence is observed in 91% of fistula cases and stapes erosion in 69%. Severe hearing loss was present preoperatively in four (14%) cases. Bone pate was used to repair the fistula with CT-documented restoration of the otic capsule in 11/13 cases with postoperative imaging. When bone pate was not used, the otic capsule defect persisted.CONCLUSIONS:
Spontaneous repair of the otic capsule following treatment of cholesteatoma is expected to be an uncommon occurrence. Repair of the fistula with bone can result in long-lasting restoration of the otic capsule. LEVEL OF EVIDENCE 4. Laryngoscope, 1281643-1648, 2018.Palavras-chave
