[Analysis of the therapeutic effect of drug-induced sleep endoscopy assisted multi plane surgery for OSAHS].

Objective:To analyze the surgical efficacy of drug-induced sleep endoscopy（DISE） localization-assisted treatment for obstructive sleep apnea-hypopnea syndrome（OSAHS）, and to explore the guiding role of DISE in multi-plane surgery for OSAHS. Methods:A retrospective analysis was conducted on patients with OSAHS who underwent surgical treatment in the Department of Otorhinolaryngology Head and Neck Surgery of the Second Hospital of Jilin University from January 2020 to October 2023. All patients underwent DISE examination and electronic nasopharyngoscopy combined with Müller examination（ENMM）, and surgical plans were formulated based on the results of each examination. Among them, a total of 103 patients received surgical plans guided by DISE and were named the DISE group; a total of 93 patients received surgical plans guided by ENMM and were named the ENMM group. Both groups of patients underwent palatopharyngeal and/or tongue root level surgeries simultaneously. Before the operation, all cases underwent polysomnography（PSG）, Epworth Sleepiness Scale（ESS）, and snoring scale（SS） scoring. At 6 months after the operation, all patients returned to the hospital for re-examination of the above-mentioned examinations and scales to observe the status of body mass index（BMI）, apnea-hypopnea index（AHI）, lowest blood oxygen saturation（LSaO2）, and scale scores. Propensity score matching was used to match the two groups of patients at a 1∶1 ratio, and the subjective symptoms, objective indicators, and total effective rate of treatment before and after the operation were compared and analyzed. Results:After propensity score matching, 80 cases were included in each group. There were no significant differences in age, gender, disease duration, smoking history, whether hypertension was present, preoperative BMI, AHI, LSaO2, and ESS between the two groups（P>0.05）. During preoperative examinations, the severity of lingual root obstruction found in the DISE group was higher than that in the ENMM group. At 6 months after surgery, both groups showed improvements in ESS, SS, BMI, AHI, and LSaO2 compared to before surgery. The ESS score and improvement in LSaO2 in the DISE group were more significant, and these differences were statistically significant（P<0.05）. Conclusion:DISE has significant advantages in identifying severe tongue root obstruction. When conducting concurrent multi-plane surgeries for OSAHS patients under the guidance of DISE, the treatment effect is excellent, further confirming the practical value of DISE in the assessment and treatment of OSAHS.
