Massive Cholesteatoma With Facial Nerve, Middle and Posterior Fossa Dehiscence With Neck Extension.

Cholesteatomas can grow aggressively within the temporal bone due to the accumulation of keratin. If not treated, they can destroy surrounding structures and, therefore, cause many comorbidities. Surgery is the mainstay of treatment. We present a case of massive cholesteatoma involving the facial nerve (FN) with extension into the neck around the FN. The patient underwent a planned multidisciplinary resection of the cholesteatoma without postoperative morbidity.
