Abstract:Objective To explore and analyze the application value of correcting of nasal septum deviation under nasal endoscopy combined with temperature-controlled ablation radio-frequency in treatment of chronic sinusitis.Methods From June 2020 to June 2023, 200 patients with chronic sinusitis and nasal septum deviation who underwent nasal endoscopic sinus surgery were randomly divided into control group (combined with nasal endoscopic sinus surgery) and observation group (combined with temperature-controlled ablation radio-frequency), 100 cases in each group. The efficacy, nasal mucosal function, olfactory function, airway responsiveness and complications were compared between the two groups.Results The observation group has a better therapeutic effect than that in control group, the difference was statistically significant (P < 0.05); After surgery, compared with the control group, the observation group had a shorter saccharin clearance time (SCT), faster mucociliary clearance transport (MCT), higher nasal mucociliary transport rate (MTR), the differences were statistically significant (P < 0.05); After surgery, the observation group had better olfactory function grading than the control group, the difference was statistically significant (P < 0.05); The airway resistance at 5 Hz (R5), airway resistance at 20 Hz (R20), and resonance frequency (Fres) of the observation group were lower than those of the control group, the differences were statistically significant (P < 0.05); There was no significant difference in complications between the two groups (P > 0.05).Conclusion The combination of endoscopic nasal septum correction and temperature-controlled ablation radio-frequency for the treatment of chronic sinusitis has better clinical efficacy than endoscopic sinus surgery. It has significant advantages in improving nasal mucosal function, olfactory function, and reducing airway responsiveness, and is highly safe. It is worthy of clinical promotion and application.
