The purpose of this study was to assess the feasibility of the endoscopic transoral approach for resection of retrostyloid benign tumors.
We retrospectively reviewed 16 patients with retrostyloid parapharyngeal space (PPS) tumors resected via an endoscopic transoral approach. After separation and control of the internal carotid artery (ICA), tumors in the retrostyloid PPS were then removed under the guidance of angled endoscope (45°).
All 16 patients with retrostyloid PPS tumors were successfully removed via an endoscopic transoral approach. There were 15 schwannomas and 1 paraganglioma. Two tumors were removed en bloc, and the other 14 tumors were removed by piecemeal. In five patients, the tumor extended into the jugular foramen, and was completely removed via the transoral corridor, without cerebrospinal fluid leak. No ICA injury was encountered in any of the 16 patients.
The endoscopic transoral approach is suitable for the resection of retrostyloid PPS tumors and is associated with low morbidity.
本研究的目的是评估经口内镜入路切除茎突后良性肿瘤的可行性。
我们回顾性分析了16例经口内镜入路切除茎突后咽旁间隙（PPS）肿瘤的患者。在分离并控制颈内动脉（ICA）后，于45°角内镜引导下切除茎突后PPS内的肿瘤。
16例茎突后PPS肿瘤患者均经口内镜入路成功切除。其中有15例神经鞘瘤和1例副神经节瘤。2例肿瘤完整切除，其余14例肿瘤分块切除。5例患者肿瘤延伸至颈静脉孔，经口入路完全切除，无脑脊液漏。16例患者均未发生ICA损伤。
经口内镜入路适用于切除茎突后PPS肿瘤，且并发症发生率低。
