30 Clinical and Experimental Otorhinolaryngology Vol. 2, No. 1: 28-32, March 2009 A B Fig. 1. Type C Glomus jugulare tumor (Patient 6), arising from right jugular foramen and extending into right mastoid cavity and infralabyrinthe. A B Fig. 2. Type D Glomus jugulare tumor (Patient 5) showing intracranial extension, compressing pons and brainstem. portion of residual tumor. The remaining tumor is under obser- vation currently. In the remaining two partial resection cases, st- aged operation was planned initially. However, the patients re- fused to undergo the burden of major surgery twice after the first operation (infratemporal approach), and gamma knife surgery had to be performed as an alternative to planned staged opera- tion by neurosurgery department. Tumor was completely shrunk- en in one case, and tumor was stabilized without growing in the other case. Postoperative complications No mortality was encountered during the follow-up period, rang- ing from 17 to 275 months (mean, 71 months). Most common pos- toperative complication was transient facial palsy which occurred in 4 cases. In all 4 cases, patient showed H-B Grade IV palsy which returned to H-B Grade II palsy in a few months. Since Infratem- poral fossa approach inevitably encounters facial palsy due to transposition of facial nerve, facial palsy of grade better than H- B Grade II was excluded from the criteria of complications. In 2 cases, audiologic function was lost postoperatively. In one patient,
