Beschreibungen/Notizen

• Surgery of the infratemporal fossa (ITF) and parapharyngeal area presents a formidable challenge to the surgeon due to its anatomical complexity and limited access. Conventional surgical approaches to these regions have been too extensive and invasive with occasional sacrifice of neurovascular structure. Lesions located in the ITF–parapharyngeal space can be resected through two smaller operative corridors between the trigeminal nerve second branch (V2) and third branch (V3), or between the V3 and the temporomandibular joint (TMJ). Surgical exposure can be customized from minimum to maximum according to the tumor size and its location. The critical maneuver is the anterior or posterior translocation of the V3 to obtain best operative space. With the assistance of three-dimensional volumetric computer navigation system, vascular monitoring with Doppler probes, and intraoperative indocyanine green (ICG) examination, it is possible to locate and protect any vital neurovascular structures often involved in the tumor, which decreases the complication rates.
