Robotic-Assisted Removal of Parapharyngeal Space Tumor via a Retro-auricular Approach: A Case Report

摘要

Parapharyngeal space (PPS) tumors are rare and excised most commonly via the transcervicalapproach. A female patient presented with a left side neck swelling of size 5cm x 4cm, progressivelyincreasing in size. Radiologically a well-defined soft tissue intensity mass lesion in left parapharyngeal space (PPS) was noted suggesting paraganglioma (Schwannoma). Resection of the tumorwith robotic assistance via the retro-auricular approach was planned and resected. The roboticassistance resection of PPS mass via retro-auricular tunnel has the advantages of lessening theextent of dissection and better instrument access eliminating blind dissection.
