Abstract
|
|
|
Congenital cholesteatoma is rare, and especially so for a benign mass to grow from the squa-mous epithelium and the petrous apex as a location for this cancer. Surgery of the petrousapex cholesteatoma is challenging due to the location of the lesion and the need to preserveadjacent structures such as the dura mater, internal carotid artery, and internal auditory canal.
Imaging studies, including CT and MRI, were crucial in guiding the surgical approach. Thisreport describes a 40-year-old male patient with a large congenital cholesteatoma involvingthe petrous apex and temporal bone. The patient presented with a headache, hearing loss thatpersisted despite prior medical treatment. The cholesteatoma was surgically marsupializedthrough translabyrinthine approach, and the patient has remained stable for over 20 years.
This report underscores the importance of considering the anatomical location and relation-ships of the lesion and adjacent structures when determining the surgical approach for con-genital cholesteatoma involving the petrous apex and temporal bone.
