ZHANG Yu,DAI Xianning,ZHENG Huizhen, et al. A comparison between anterior ethmoidal nerve block and selective pterygoid canal neurotomy in the treatment of moderate-to-severe allergic rhinitis[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2021, 51(3): 230-233.
Abstract：Objective: To explore the efficacy of anterior ethmoidal nerve blockade and selective vidian nerve transection under nasal endoscopy in treating moderate to severe allergic rhinitis. Methods: A total of 125 patients with moderate to severe allergic rhinitis admitted to Wenzhou People’s Hospital from March 2017 to September 2019 were selected and divided into 2 groups according to different surgical procedures. Among them, there were 89 cases in the anterior ethmoidal nerve blockade group and 36 cases in the selective vidian nerve block group. The rhinoconjunctivitis quality of life scale (RQLQ) and clinical symptom grading were used to statistically
analyze the improvement of life quality, sneezing, nasal itching, runny nose and nasal obstruction before surgery 6 and 9 months after surgery in 2 groups respectively. Results: Compared with preoperative data, RQLQ scores, nasal itching, sneezing, runny nose, and nasal congestion clinical symptoms scores were significantly decreased in the two groups at 6 months and 9 months after surgery (P<0.01). The clinical symptom scores of nasal itching in the anterior ethmoidal nerve block group were significantly better than those in the vidian nerve cut group (P<0.01), and the clinical symptom scores of nasal itching and sneezing in the preethmoidal nerve block group were better than those in the vidian nerve cut group (P<0.05). The clinical symptom scores of runny nose and nasal congestion in the vidian nerve transection group were significantly better than those in the preethmoidal nerve group (P<0.01). Conclusion: Both anterior ethmoidal nerve blockade and selective vidian nerve transection can effectively treat allergic rhinitis, varying in the improvement degree of symptoms. For patients with obvious sneezing but unobvious nasal congestion, anterior ethmoidal nerve blockade can be considered alone; for patients with runny nose and nasal congestion as the main symptoms, selective vidian nerve blockade is recommended. For severe allergic rhinitis patients, it is recommended to combine the two procedures.
