Background The use of laryngeal mask airway (LMA) ventilation in surgeries to be performed in upper tracheal stenosis has been reported in the case series. However, there is no generally accepted standardized approach for the use of LMA. In this study, LMA usage areas and advantages of trachea surgery were examined.

Methods The records of 21 patients who underwent tracheal surgery using LMA ventilation between March 2016 and May 2020 were evaluated retrospectively. The patient data were analyzed according to age, gender, mean follow-up time, surgical indication, mean tracheal resection length, anastomosis duration, mean oxygen saturation, mean end-tidal CO₂ levels, and postoperative complications.

Results Four patients were female and 17 were male, their median age was 43 (11–72 range) and the mean follow-up time was 17.6 months. The most common surgical indication was postintubation tracheal stenosis. The mean tracheal resection length was 26.6 mm and the mean anastomosis duration was 11.3 minutes. The mean pulse oximetry and mean end-tidal CO₂ during laryngeal mask ventilation was 97.6% ± 2.1 and 38.1 ± 2.8 mm Hg, respectively. Postoperative complications were higher in patients with comorbidities.

Conclusion LMA-assisted tracheal surgery is a method that can be used safely as a standard technique in the surgery of benign and malignant diseases of both the upper and lower airway performed on pediatric patients, patients with tracheostomy, and suitable patients with tracheoesophageal fistula.

背景 病例系列报道了在上气管狭窄的手术中使用喉罩通气 (LMA) 通气。但是，对于 LMA 的使用，没有普遍接受的标准化方法。在这项研究中，检查了 LMA 的使用领域和气管手术的优势。

方法 回顾性评价2016年3月至2020年5月21例采用LMA通气进行气管手术的患者的病历。根据年龄、性别、平均随访时间、手术适应症、平均气管切除长度、吻合时间、平均氧饱和度、平均呼气末CO ₂水平和术后并发症对患者资料进行分析。

结果 女性4例，男性17例，中位年龄43岁（11～72岁），平均随访时间17.6个月。最常见的手术指征是插管后气管狭窄。平均气管切除长度为 26.6 mm，平均吻合时间为 11.3 分钟。喉罩通气期间的平均脉搏血氧饱和度和平均呼气末 CO _{2分别为 97.6% ± 2.1 和 38.1 ± 2.8 mm Hg。}合并症患者的术后并发症较高。

结论 LMA 辅助气管手术是一种可安全地作为标准技术用于儿科患者、气管切开术患者和适合气管食管瘘患者的上下气道良恶性疾病的手术。
