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