Clinical application of a curved video suspension laryngoscope in laryngeal surgery

Abstract

Background Suspension laryngoscopy (SL) is a common procedure performed by otolaryngologists. Studies have shown that adverse effects occur often during SL. Objectives To demonstrate the value of clinical application, this study compared the surgical time and postoperative oropharyngeal complications of SL using a novel curved video suspension laryngoscope with those of conventional SL. Materials and methods A total of 185 patients who underwent curved video SL, and 128 who underwent conventional SL were included. Characteristics including age, sex, body mass index (BMI), postoperative complications, and surgical time were compared in conventional and curved SL patients diagnosed with vocal cord polyps. Results The use of a curved laryngoscope significantly reduced surgical time (median, 10 min IQR 7–15 vs. 15 min IQR 11–20; p < .001) and produced fewer postoperative complications (2 vs. 39, p < .001) than that of conventional SL. Patients undergoing conventional SL experienced an 18.8-fold higher complication risk vs. those undergoing curved video SL (adjusted OR = 18.80; 95% CI = 6.47–54.60). Conclusions and significance Curved video SL provided a clear surgical field, consumed less surgical time, and yielded fewer complications than conventional SL. This procedure is a cost-effective, minimally invasive alternative to conventional SL.
