[Petrous bone lesions].
OBJECTIVE
We evaluated the results of treatment and follow-up of patients with petrous bone lesions.


METHODS
We retrospectively evaluated 13 patients (5 females, 8 males; mean age 33.8+/-17.4 years; range 4.5 to 65 years) who were treated and followed-up for petrous bone lesions between 1990 and 2004. The diagnoses were cholesterol granuloma (n=2; 15.4%), chondrosarcoma (n=1; 7.7%), and cholesteatoma (n=10; 76.9%).


RESULTS
Patients with cholesterol granuloma had complaints of cephalgia and diplopia while those with cholesteatoma complained of otorrhea and hearing loss. One patient with cholesterol granuloma and eight patients with cholesteatoma underwent surgical operations with the use of middle skull base approach (n=1), transcochlear approach (n=2), translabyrinthine approach (n=1), and tympanopetrosectomy (n=5). Two cases with congenital cholesteatoma and one patient with cholesterol granuloma refused surgical intervention and were only followed-up.


CONCLUSIONS
Besides surgical intervention, follow-up by computed tomography or magnetic resonance imaging may be considered in patients with incidental petrous bone lesions, presenting with limited symptoms.
