[Clinical efficacy of endoscopic plasma resection of juvenile nasopharyngeal angiofibroma].

To investigate the clinical effect of plasma resection of juvenile nasopharyngeal angiofibroma（JNA） under nasal endoscope. The clinical data of 12 cases with JNA treated in the Department of Otorhinolaryngology and head and neck surgery of the 940th Hospital from 2015.01 to 2020.01 were analyzed retrospectively. All of them were young males. Imaging examination, digital subtraction angiography（DSA） and selective blood supply artery embolization were performed before operation, and then plasma was used to remove the tumor under nasal endoscope. The patients were followed up for at least 30 months. During the follow-up, the nasal cavity was observed under nasal endoscope and the tumor recurrence was observed by imaging examination. In 12 cases, the vision was clear, the amount of bleeding was less, the operation time was within 2 h, and the postoperative recovery time was short. 12 cases were followed up and no tumor recurrence was found by nasal endoscopy and imaging examination. Selective external carotid artery embolization before operation and plasma resection of JNA under nasal endoscope during operation is a safe and effective treatment, which can effectively improve the cure rate and reduce the recurrence rate.
