Objectives: Nasopharyngectomy performed via a solely endoscopic approach has limitations in access and feasibility, particularly regarding management of the carotid artery. To address these limitations, we report three cases with one cadaver dissection where nasopharyngectomy was performed via a combined open lateral an endoscopic approach. We highlight the benefits and technical considerations for this operative technique.
Study Design: Case Series
Methods: Patients diagnosed with recurrent nasopharyngeal carcinoma (NPC) that underwent combined open lateral and endoscopic nasopharyngectomy from 2016-2020 were analyzed. A cadaver dissection was also performed.
Results: We present the details of the approach and follow-up in three patients with recurrent nasopharyngeal carcinoma. Briefly, a preauricular incision is extended down to the neck. The zygoma and mandibular ramus can be removed and replaced if required. V3, the pterygoid plates and the eustachian tube can be resected or mobilized. The carotid artery may be identified proximally in the neck and traced to the skull base, where the carotid canal may be drilled to the level of the foramen lacerum and protected with a pledget. Then, tumor mucosal cuts are made via an endoscopic endonasal approach and connected to the lateral exposure. No carotid artery injuries occurred.
Conclusion: The combined open lateral approach and endoscopic nasopharyngectomy technique is a useful technique in salvage patients. It provides excellent control of major vessels, adequate access to the carotid canal, V3, and remainder of the skull base, and cervical protection.
