ROSIQUE-LOPEZ, L.; ROSIQUE-ARIAS, M.  e  SANCHEZ-CELEMIN, F.J.. Pterygopalatine fossa schwannoma: Endoscopic approach. Neurocirugía [online]. 2010, vol.21, n.5, pp.405-410. ISSN 1130-1473.

We expose the anatomical characteristics of the pterygopalatine fossa (FPP) and the pathology that can cause it. Below is the surgical experience in a case of schwannoma of FPP five centimeters in diameter that could be removed by transnasal endoscopic surgery, being unnecessary an external surgery. Schwannomas constitute the 8-10% of intracranial tumors, normally localized in the vestibular branch of the VIII cranial nerve. A schwannoma of a branche of the trigeminal lnerve in the pterigopalatine fossa is exceptional.
