Numerous surgical approaches have been employed to access the infratemporal region, some of them being the transoral, transanal, transpalatine
, transzygomatic, transcervical, and extended maxillectomy approach .
Numerous open surgical approaches have been employed traditionally, based on the tumor extensions, like transpalatine
, lateral rhinotomy, midfacial degloving, and neurosurgical approaches in cases with intracranial extension .

He had previously undergone two operations elsewhere, both via a transpalatine
approach, and neither had been successful.
Osseous atresia may require choanal reconstruction or transpalatine
resection of the thick vomer.
(3) Shape of transpalatine
process: The transpalatine
process, at the latero-caudal corner of the palatine bone, was measured as the ratio of its length over its width.
[14,15] In addition, Kornfehl et al have described a relatively new transpalatine approach that does not require an osteotomy.
Transpalatine excision of a cavernous hemangioma of the infratemporal fossa.
