The Combined Endoscopic Transcervical - Transoral Robotic Approach for Resection of Parapharyngeal Space Tumors

摘要

Background: The parapharyngeal space (PPS) presents challenges during surgical exposure. Parapharyngeal space tumors (PPST) are routinely resected by transcervical approach using blunt finger dissection, while the critical part of the operation is performed in a blind fashion, applying pressure on the tumor, increasing the risk of tumor spillage and of neurovascular injury. Large PPST or those located high at the lateral skull base, often require mandibulotomy, or infratemporal fossa approach, baring considerable morbidity.
