A Case of Image-Guided Acoustic Neuroma Surgery via Middle Cranial Fossa Approach / 대한이비인후과학회지

ABSTRACT

Acoustic tumor which originates from the vestibular nerve is the most common neoplasm to be found at the cerebellopontine angle. The surgical approaches currently used for the acoustic tumor are the middle cranial fossa, the translabyrinthine, the suboccipital, and the combined approaches depending on the size, location, and growth rate of the tumor and the hearing level, age, and general health condition of the patient. The complex and variable anatomy and the proximity of important structures encountered during acoustic tumor surgery especially when using the middle cranial fossa approach, may make it a tough job even for the experienced surgeon. Recently, developed image-guided system may be an important step in reducing the incidence of the complication. In the present research, authors used image-guided system during acoustic tumor surgery via middle cranial fossa approach, and with good result.
