喉软化症是最常见的喉异常，影响45 - 75%的先天性喘鸣婴儿。喉软化是由于吸气时声门上组织动态脱垂到气道内所致。声门上组织脱垂可引起不同程度的气道阻塞和吸气性喘鸣。大多数婴儿有轻微的疾病，并得到预期的治疗。中度和重度疾病的患者采用胃食管反流治疗、改良喂养方式和手术干预。20%的婴儿需要手术干预。声门上成形术是手术治疗的主要方法；很少需要气管切开术。
Laryngomalacia is the most common laryngeal anomaly, affecting 45–75 % of infants with congenital stridor. Laryngomalacia is due to the dynamic prolapse of supraglottic tissues into the airway during inspiration. Prolapse of supraglottic tissues produces a variable amount of airway obstruction and inspiratory stridor. A majority of infants have mild disease and are managed expectantly. Those with moderate and severe disease are managed with gastroesophageal reflux therapy, feeding modifications, and surgical intervention. Surgical intervention is required in 20 % of infants. Supraglottoplasty is the mainstay of surgical treatment; tracheostomy is rarely needed.
