Kt. Pitman et al., A TRANSSPHENOIDAL APPROACH TO PETROUS APEX LESIONS USING ENDOSCOPIC SINUS SCOPES, American journal of rhinology, 7(6), 1993, pp. 257-260
The authors describe biopsy of a petrous apex lesion via a transnasal,
transsphenoidal endoscopic approach. Various surgical approaches to t
he petrous apex are discussed as well as our experience using the endo
scopic approach. We propose that this approach can be refined for futu
re use as a method for biopsy and permanent fistulization of cystic pe
trous apex lesions that encroach on the sphenoid sinus.
