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.

Chinese Abstract

背景：悬吊式喉镜检查 (SL) 是由耳鼻喉科医师进行的常见手术。研究表明, 在 SL 过程中经常发生不良影响。

目的：为了证明临床应用价值, 本研究比较了使用新型弯曲视频悬挂喉镜的SL手术与传统 SL 的手术时间和术后口咽并发症。

材料与方法：共纳入185例接受弯曲视频SL的患者, 128例接受传统SL的患者。比较常规和弯曲 SL 患者的年龄、性别、体重指数 (BMI)、术后并发症和手术时间等特征。这些患者被诊断患有声带息肉。

结果：与传统的 SL相比, 弯曲喉镜的使用明显缩短了手术时间（中位数, 10 分钟 IQR 7–15 相较于 15 分钟 IQR 11–20； p < .001) 并产生更少的术后并发症（2 相较于 39, p < .001)。接受传统 SL 的患者经历了比接受弯曲视频 SL 的患者高18.8 倍的并发症风险（调整后的 OR = 18.80；95% CI = 6.47–54.60)。

结论和意义：与传统的 SL相比, 弯曲视频SL可提供清晰的手术区域, 手术占时更少, 并且 产生的并发症更少。该手术是传统 SL 的一种具有成本效益的微创替代方案。
