Abstract：
OBJECTIVE: This study aimed to validate the feasibility of an endoscopic endonasal combined transoral medial approach for treating lesions in the nasopharynx, parapharyngeal space (PPS), and jugular foramen.
METHODS: Anatomical and imaging information of six patients who underwent surgery via this approach were reviewed and analyzed.
RESULTS: The feasibility and advantages of the endoscopic endonasal combined transoral medial approach, which uses an inside-to-outside medial surgical corridor, were identified. Total resection was achieved in 3 cases with benign tumors. Safe resection margins were obtained in 2 cases with recurrent nasopharyngeal carcinoma (NPC). Pathological biopsy of NPC lesion between the Eustachian tube and arterial sheath was achieved. The internal carotid artery (ICA) was accurately located and protected in all cases and no complications occurred.
CONCLUSIONS: Lesions in the nasopharynx, PPS, and jugular foramen can be directly assessed via this approach. The ICA can be well identified during the surgery.

摘要：
目的：本研究旨在验证鼻内镜经鼻联合经口内侧入路治疗鼻咽病变的可行性。咽旁间隙(PPS),和颈静脉孔.
方法：回顾并分析了6例通过该方法进行手术的患者的解剖学和影像学信息。
结果：鼻内镜经口内侧入路的可行性和优势，使用从里到外的内侧手术走廊，已确定。良性肿瘤3例全切除。2例复发性鼻咽癌（NPC）获得了安全的切除边缘。对咽鼓管和动脉鞘之间的NPC病变进行病理活检。所有病例颈内动脉（ICA）定位准确，保护良好，无并发症发生。
结论：鼻咽部病变，PPS,颈静脉孔可以通过这种方法直接评估。在手术期间可以很好地识别ICA。
