Surgical approach analysis of endoscopic resection of juvenile nasopharyngeal angiofibroma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

Objective:To investigate the surgical approach for the resection of juvenile nasopharyngeal angiofibroma（JNA） under nasal endoscopy. Methods:The clinical data of 87 patients undergoing endoscopic resection of nasopharyngeal fibroangioma were retrospectively analyzed. We classified JNA according to tumor site, size, invasion scope and anatomic position relationship between tumor and midline of pupil. Three endoscopic surgical approaches were selected according to the classification, and the postoperative symptoms, complications and recurrence were investigated and analyzed. Results:The tumor resection rate of 87 cases by nasal endoscopic surgery was 100%. Thirty-five cases were approached through the middle nasal passage（small tumors located in the nasal sinuses and pterygopalatine fossa）, forty-five cases were approached through the lateral wall of the nasal cavity（tumor invaded the pterygopalatine fossa but did not exceed the midline of the pupil） , and seven cases were approached via the lateral wall of nasal cavity + ipsilateral anterior wall of maxillary sinus（tumor invaded the infratemporal fossa beyond the midline of pupil or invaded the cavernous sinus and the middle cranial fossa epidural）, Postoperative patients with nasal congestion, nasal bleeding, headache, dizziness, vision loss and other symptoms showed varying degrees of improvement. No surgical death or intracranial infection occurred. The postoperative follow-up was 6-78 months, and the recurrence rate was 3.44%. Conclusion:Endoscopic resection of nasopharyngeal fibroangioma is the main treatment method for JNA. Selecting suitable endoscopic approach to resect JNA, To maximize the advantage of nasal endoscopic equipment according to the inherent anatomical space of the human nasal cavity, In order to achieve the purpose of JNA resection, reduce intraoperative and postoperative complications, reduce the recurrence rate and improve the prognosis.
