Abstract:
The transpetrosal approach to the anterior portion of a brain stem lesion with intact hearing is often limited by portions of the labyrinth. The technique of partial labyrinthectomy, by which the posterior and superior semicircular canals, maximizes surgical exposure while preserving hearing. We report the case of a patient who underwent a modified partial labyrinthectomy involving resection of the posterior semicircular canal only in the area of the labyrinth. Technical modification of the partial labyrinthectomy approach simplifies tumor removal while preserving hearing.
