Osteoplastic Transpetrosal Approach

ABSTRACT

The main two problems in the standard transpetrosal approach are a cosmetic deformity and the cerebrospinal fluid (CSF) leakage. However, until now a few technical innovations has been introduced to overcome these problems. Domestically, there is no reports concerning this technique. We introduce a simple and easy technique of cosmetic reconstruction with a split-thickness mastoid bone flap after transpetrosal approach in three tumorous conditions at cerebellopontine region. This simple technique provides a superior cosmetic result, a significant reduction in uncomfortable symptoms, and a possibility of the CSF leakage.
