[Pterygopalatine fossa schwannoma. Endoscopic approach].
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.
