An analysis of petrous bone cholesteatomas treated with translabyrinthine transotic petrosectomy.
CONCLUSIONS
In cases of petrous apex cholesteatoma, radical removal should be prioritized over an unreasonable sparing of hearing or facial symmetry. Restoration of facial nerve function is achievable by reanimation procedures.


OBJECTIVE
To analyze clinical manifestations, surgical findings, and postoperative functional results of petrous apex cholesteatoma.


METHODS
From 1995 to 2012, 34 cases of petrous apex cholesteatoma underwent operations. Clinical and surgical findings and postoperative functional outcomes were analyzed retrospectively.


RESULTS
Hearing loss was the most common symptom in 95% of patients, followed by otorrhea in 64% and facial palsy in 59%. Four patients had recurrent facial palsy. In eight (24%) patients petrous apex cholesteatomas were recurrent or iatrogenic in origin. The supralabyrinthine and massive type of petrous bone cholesteatoma were the most common types, followed by, infralabyrinthine-apical, infralabyrinthine, and apical. Among 18 cases with facial nerve paralysis, 8 underwent hypoglossal-facial nerve anastomosis, 4 underwent rerouting and end to end anastomosis, 3 of them did not undergo any treatment because of the duration of facial palsy (> 3 years), and another 3 patients for whom we had recommended facial-hypoglossal anastomosis did not accept the operation. There were no major complications. Recurrence was observed in two (5%) cases.
