Laryngomalacia is the condition responsible for 75% of the cases of stridor in children aged up to 30 months, in which there is supraglottic collapse during inhalation. Inspiratory stridor is a characteristic telltale. As many as 20% of the patients are severely affected and require surgery. Supraglottoplasty is the procedure of choice and the presence of comorbidities is the most relevant prognostic factor for surgery success.
To describe a series in a tertiary pediatric hospital, its success rates, and surgery prognostic factors.
This retrospective cohort study enrolled 20 patients submitted to supraglottoplasty between July 2007 and May 2011.
Thirteen (65%) patients were males; mean age at the time of the procedure was 6.32 months. Endoscopic examination showed that 12 subjects had combined forms of laryngomalacia, 40% had associated pharyngomalacia, and three also had tracheomalacia. Thirteen subjects had isolated laryngomalacia and seven had gastroesophageal reflux disease. Fifteen (75%) patients underwent aryepiglottic fold resection. After the procedure, eleven patients were asymptomatic and two required tracheostomy. Presence of comorbidities was the strongest predictor of unfavorable postoperative outcome (p = 0.034).
Supraglottoplasty is a safe therapeutical procedure for select patients with laryngomalacia.
先天性喉软化症是导致 30 月龄以下儿童 75%喘鸣的原因，其在吸气时会出现会厌上塌。吸气性喘鸣是其特征性表现。多达 20%的患者病情严重，需要手术。杓会厌皱襞切除术是首选术式，并存疾病是手术成功的最相关预后因素。
描述一家三级儿科医院的病例系列，其成功率及手术预后因素。
本回顾性队列研究纳入了 2007 年 7 月至 2011 年 5 月间接受杓会厌皱襞切除术的 20 例患者。
13 例（65%）患者为男性；手术时的平均年龄为 6.32 个月。内镜检查显示 12 例存在混合性先天性喉软化症，40%存在咽成形术后软化，3 例还存在气管软化。13 例存在单纯性先天性喉软化症，7 例存在胃食管反流病。15 例（75%）患者行杓状软骨后联合切除术。术后，11 例患者无症状，2 例需要行气管切开术。并存疾病是术后不良结局的最强预测因素（p=0.034）。
对于选择的先天性喉软化症患者，杓会厌皱襞切除术是一种安全的治疗方法。
