title: [Extended subtemporal approach to the subtemporal fossa and related structures - analysis of the surgical technique based on cadaver simulation].
abstract: The aim of the study was to present consecutive stages of the extended subtemporal approach (ESA). Seven simulations of ESA were performed on non-fixed human cadavers without any known pathologies in the head and neck. The consecutive stages of the procedure were documented with photographs and schemes. The starting point for ESA is osteotomy of the zygomatic arch and craniectomy including the greater wing of the sphenoid bone. Dislocation or removal of subtemporal fossa contents allows one to penetrate its inside and related structures. Additional widening of inspection allows osteotomy of the condyloid process of the mandible. ESA is a reproducible technique which provides surgical penetration of the subtemporal fossa and related structures. This approach is particularly useful in the surgical treatment of tumours expanding in the orbit, maxillary sinus, pterygopalatine fossa, nasopharynx, sphenoid sinus, cavernous sinus, parapharyngeal space, retromandibular fossa and surroundings of the petrosal part of the internal carotid artery.
