Influence of radiofrequency ablation of inferior turbinate on nasal structure and airway resistance in patients with chronic rhinosinusitis
Objective To explore the influence of radiofrequency ablation of inferior turbinate on nasal structure and airway resistance in patients with chronic rhinosinusitis.Methods 64 patients with chronic rhinosinusitis in Zhengzhou Children's Hospital from January 2019 to March 2024 were studied and divided into control group(n=32,endoscopic sinus surgery)and observation group(n=32,endoscopic sinus surgery combined with radiofrequency ablation of inferior turbinate)by adopting the random envelope method.The surgery-related indicators,efficacy,nasal structure,airway resistance,nasal mucociliary clearance function and complications were compared between both groups of patients.Results There was no difference in intraoperative blood loss between both groups(P＞0.05).The hospital stay in observation group was shorter than that in control group(P＜0.05).The total effective rate was higher in observation group than that in control group(P＜0.05).Compared with before treatment,the vertical distance between the lower edge of the inferior turbinate and the nasal floor on the spacious side and the narrow side and the horizontal distance between the innermost edge of the inferior turbinate and the nasal septum were increased in both groups after treatment,and the observation group had longer distances than the control group(P＜0.05).The maximum thicknesses of the horizontal direction of the inferior turbinate on the spacious side and the narrow side of the two groups of patients were decreased after treatment compared with those before treatment,and the observation group had thinner thicknesses(P＜0.05).Compared with before treatment,the total respiratory impedance(Z5),total airway resistance(R5)and resonance frequency(FRES)were declined in both groups after treatment,and the Z5,R5 and FRES in observation group were lower compared to control group(P＜0.05).The mucociliary transport rate(MTR)and mucociliary clearance rate(MCT)in both groups after treatment were risen compared to before treatment,and the observation group had higher MTR and MCT.Compared with before treatment,the saccharin clearance time(SCT)was shortened in both groups after treatment,and the SCT in observation group was shorter than that in control group(P＜0.05).After treatment,the nasal endoscopic Lund-Kennedy score in observation group was lower than that in control group(P＜0.05).The total incidence rate of complications in observation group was lower than that in control group(P＜0.05).Conclusion Compared with endoscopic sinus surgery alone,endoscopic sinus surgery combined with radiofrequency ablation of inferior turbinate for patients with chronic rhinosinusitis did not increase intraoperative blood loss,but could better shorten hospital stay,enhance efficacy,improve nasal structure and nasal mucociliary clearance function,reduce airway resistance,and lower the incidence rates of complications,and it had application value.
