Methods: The da Vinci Robotic Surgical System (Si) was used for complete resection of four skull base tumors. Two pleomorphic adenomas in the parapharyngeal space, one pleomorphic adenoma in the infratemporal fossa and one metastatic papillary thyroid cancer node in the high retropharyneal nodal basin were resected. A transpalatal approach was used to access the infratemporal fossa (n=1) and re...

OBJECTIVES/HYPOTHESIS In an effort to decrease morbidity, skull base surgeons have explored less invasive approaches to the infratemporal fossa, including endonasal-endoscopy, minicraniotomies, and transantral endoscopic and microscopic corridors. This project presents quantitative data that assesses the practicality, and volumetric exposure afforded by endonasal and open approaches to the infr...

Background Paragangliomas are rare neural crest tumors that can manifest in the head and neck as either functional or more commonly as nonfunctional lesions. Paragangliomas of the infratemporal fossa are exceedingly rare, with no more than a handful of documented cases. Like other tumors of this space, surgical management is challenging on account of complex anatomy and nearby critical structur...

Cross-sectional imaging is an indispensable tool in the investigation of parapharyngeal space and infratemporal fossa pathologies. Computed tomography and magnetic resonance imaging exquisitely display the complex anatomy of this region and provides accurate spatial localization of pathology, differential diagnosis and vital information for treatment planning.

Plemorphic adenoma is a frequent benign tumor of the major salivary glands. It could also develop from accessory salivary glands. We are reporting an extremely rare case of pleomorphic adenoma developing from the infratemporal space. The final diagnosis was based on histological confirmation. The treatment was mainly a complete resection via an anterior transmaxillary approach. Diagnosis, clini...
