Low-temperature plasma radiofrequency in nasal endoscopic surgery for juvenile nasopharyngeal angiofibroma / 医学研究生学报

ABSTRACT

Objective The aim of this article was to investigate the effect of nasal endoscopic surgery (NES) using low-temperature plasma radiofrequency (LTPRF) in the treatment of juvenile nasopharyngeal angiofibroma (JNA). Methods We retrospectively analyzed the clinical data on 38 cases of JNA treated by NES+LTPRF (n = 26) or conventional surgical resection (control, n = 12) in Drum Tower Hospital of Nanjing University School of Medicine from January 2012 to December 2018. We compared the operative time, postoperative Lund-Mackay endoscopy scores (LMES), incidence of complications, postoperative recovery, rate of recurrence, and Visual Analogue Scale (VAS) scores between the two groups of patients. Results The rates of LMES gradesⅠ and Ⅱ were significantly higher while those of grades Ⅲ and Ⅳ remarkably lower in the NES+LTPRF than in the control group (P < 0.05). Compared with the controls, the patients of the NES+LTPRF group showed markedly shorter time of nasal mucosa epithelialization ([3.5 ± 0.1] vs [2.3 ± 0.1] mo, P < 0.05) and lower rates of postoperative complications (38.5% vs 7.7%, P < 0.05), recurrence (16.7% vs 3.8%, P < 0.05), and VAS scores at 3 days, 2 months, 6 months and 12 months after surgery (P < 0.05). Conclusion NES+LTPRF is an effective strategy for the treatment of juvenile nasopharyngeal angiofibroma and worthy of a wide clinical application.
