MICROSURGICAL TREATMENT OF LARGE PETROCLIVAL CHOLESTEATOMA / 解放军医学杂志

ABSTRACT

To improve the microsurgical curative effect of petroclival cholesteatoma (PCC), 52 patients harbouring PCC removed from 1993 to 2002 were analyzed retrospectively. Of all patients in this group, total tumor removal was achieved in 47 patients (90%), subtotal removal in 5 (10%). The new cranial nerve injuries occurred postoperatively in 4. Operative death occurred in 1 patient due to severe lung infection (1 9%). The key goal of surgical resection of the tumor was good. Suitable basicranial approaches and skillful microsurgical technique can increase the total removal rate, and decrease its mortality and morbidity.
