Surgical Outcome of Mandibular Swing Approach for Infratemporal Fossa Tumors

Infratemporal fossa masses are rare. The largest series is probably of Fisch describing his approaches in 51 patients.1 There are numerous approaches for these masses with their own pros and cons. For instance, Fisch type C2 approach provides good exposure but is associated with permanent hearing loss. Preauricular transzygomatic, maxillary swing,3 and transantral4 approaches provide good exposure but are insufficient for parapharyngeal extension. Endoscopic approaches need a good understanding of the endoscopic anatomy, and are difficult. Mandibular swing provides good exposure with limitation for the intracranial extension.5 We describe our experience of ten cases of these masses done with the mandibular swing approach.
