====== Glossopharyngeal Cochlear Triangle ====== The [[far lateral transcondylar craniotomy]] is the standard approach for [[posterior inferior cerebellar artery aneurysm]] exposure through the microsurgical dissection in the [[vagoaccessory triangle]] (VAT). However, the extended [[retrosigmoid craniotomy]] and dissection through the [[glossopharyngeal-cochlear triangle]] (GCT) may be more appropriate when the patient has an aneurysm arising from a high-riding [[vertebral artery]] (VA)-PICA origin.
