Abstract
ObjectiveTraditionally tumors of the parapharyngeal space (PPS) are resected through transcervical approaches. More recent approaches include endoscopic approaches or transoral robotic surgery (TORS) without directions on when to use which approach. Our objective was to find objective parameters to choose the most suitable approach. MethodsIt is a retrospective study containing 6 patients from May 2019 to May 2021 with tumors of the PPS treated in the Department of Otolaryngology and Head-Neck Surgery at the Hospital of Lucerne, Switzerland. ResultsThe data was analysed in average 53 months after surgery. Tumor resection was completed with TORS in 3 patients and endoscopically in 3 patients. Mean operation time was 114 min. No major complications occurred. No evidence of tumor was found in magnetic resonance imaging studies postoperatively in all patients. ConclusionWe conclude that a resection via TORS or endoscopic technique is safe and effective. Furthermore, we postulate that the further a tumor is located in the upper lateral area of the PPS, an approach via TORS is less possible.
