  • Title: [Petrous bone cholesteatoma: surgical strategy].
    Author: Pareschi R, Destito D, Righini S, Falco Raucci A, Mincione A, Colombo S.

    Abstract:
    Petrous bone cholesteatoma is a rare pathology which grows slowly and is often asymptomatic. This work presents a series of 25 cases of Petrous bone cholesteatoma and discusses the diagnostic impact, the surgical approach, the results and the complications. Currently our surgical orientation favors translabyrinthine and transcochlear approaches which, better than other ones, allow both radical excision of the lesion and preservation of the main neuro-vascular structures. Out of the 25 patients undergoing surgery, 22 were treated with the translabyrinthine (6 cases) or transcochlear (16 cases) approaches, in 1 case an infratemporal type A approach was used while the remaining 2 were treated with a median cranial fossa approach. Paralysis of the facial nerve is the most dreaded complication, particularly when a deficit is already present prior to surgery. In just a few cases did the hearing justify an attempt at preservation but in no case should this compromise radical removal of the cholesteatoma.
