Objective:To explore the effect of different surgical methods on the repair of velopharyngeal insufficiency(VPI)af-ter cleft palate surgery.Methods:The clinical data of 94 patients with VPI after cleft palate surgery were retrospectively analyzed.45 patients who received Furlow double-opposing Z-plasty were included in Furlow group,and 49 patients who adopted Sommerlad levator veli palatini reconstruction were enrolled as Sommerlad group.The patients were followed up for 12 months after surgery,and the im-provement conditions of speech intelligibility,nasal resonance,nasal air leakage and velopharyngeal function were analyzed.Results:At 12 months after surgery,there was no statistically significant difference in the velopharyngeal closure rate between the Sommerlad group and the Furlow group(P＞0.05).The speech intelligibility and nasal resonance recovery degree in the Furlow group and the Sommer-lad group were better than those before surgery,and the above indicators in the former group were higher than those in the latter group(P<0.05).The audibility rate of postoperative nasal leakage in the Furlow group and the Sommerlad group was lower than that before surgery,and the audibility rate in the latter group was lower than that in the former group(P<0.05).Conclusion:Furlow double-op-posing Z-plasty for VPI after cleft palate surgery is more ideal in improving speech intelligibility and nasal resonance,while Sommerlad palatoplasty demonstrated superior improvement in speech outcomes and reduced nasal air emission rates compared to conventional tech-niques,with both parameters contributing to enhanced velopharyngeal function.Clinically,it is necessary to select the surgical method according to the actual situation of patients.
