Exploring and Analyzing the Application Value of Endoscopic Nasal Septum Deviation Correction Combined with Low-Temperature Plasma Radiofrequency Ablation in the Treatment of Chronic Sinusitis

Objective: To explore the clinical efficacy and application value of endoscopic nasal septum deviation correction combined with low-temperature plasma radiofrequency ablation in the treatment of chronic sinusitis. Methods: Among the patients with chronic sinusitis admitted to our hospital, 70 patients admitted from January 2023 to January 2025 were selected as the observation subjects. All patients underwent endoscopic nasal septum deviation correction surgery and were divided into two groups based on the order of admission. The first 35 patients admitted were designated as the control group and underwent combined endoscopic sinus surgery. The latter 35 patients admitted were designated as the observation group and underwent combined low-temperature plasma radiofrequency ablation. The postoperative nasal mucosal function, olfactory function, airway reactivity, and occurrence of complications were observed in both groups to evaluate the therapeutic efficacy. Results: (1) Nasal mucosal function. The observation group had a shorter postoperative saccharin clearance time compared to the control group (P < 0.05). The nasal mucociliary clearance rate was higher in the observation group than in the control group (P < 0.05). (2) Olfactory function. The olfactory function grading in the observation group was superior to that in the control group (P < 0.05). (3) Airway reactivity. The observation group exhibited lower postoperative airway resistance at 5 Hz and 20 Hz compared to the control group (P < 0.05). Additionally, the resonance frequency was lower in the observation group than in the control group (P < 0.05). (4) The incidence of complications was similar between the two groups (P > 0.05). (5) The total therapeutic efficacy rate in the observation group was superior to that in the control group (P < 0.05). Conclusion: Endoscopic nasal septum deviation correction combined with low-temperature plasma radiofrequency ablation in the treatment of patients with chronic sinusitis can promote the recovery of nasal mucosal function, improve olfactory function, alleviate airway reactivity, and demonstrate good safety and significant therapeutic efficacy.
