Management of subglottic stenosis (SGS) in children is still a challenge to Otorhinolaryngologists. Balloon laryngoplasty (BLP) is an endoscopic procedure, first described in 1984 for the treatment of airway stenosis. It shows promising results and seems to be more effective than other procedures.
To present our experience with BLP in children with SGS.
Prospective study of children diagnosed with acute subglottic stenosis, i.e., stenosis with granulation tissue. They underwent direct laryngoscopy under general anesthesia and dilatation of the stenotic segment with angioplasty balloon. They were followed up and a second laryngoscopy was performed one week later.
Eight children were included in this study between June 2009 and October 2010. Four had Grade 3 SGS, three had Grade 2 SGS and one had Grade 1 SGS. By the second examination, two children presented with asymptomatic Grade 1 SGS, while the other six presented with normal airway and remained asymptomatic.
BLP seems to be an effective treatment for acute SGS. We need more studies to refine our knowledge concerning efficacy rates, safety and indications for balloon dilatation.
介绍我们在儿童声门下狭窄（SGS）患者中应用球囊扩张术（BLP）的经验。
对 2009 年 6 月至 2010 年 10 月期间诊断为急性声门下狭窄（即伴有肉芽组织的狭窄）的患儿进行前瞻性研究。患儿在全身麻醉下接受直接喉镜检查，并使用血管成形球囊扩张狭窄段。对患儿进行随访，在一周后再次进行喉镜检查。
本研究共纳入 8 例患儿。其中 4 例为 3 级 SGS，3 例为 2 级 SGS，1 例为 1 级 SGS。第二次检查时，2 例患儿无症状性 1 级 SGS，而其余 6 例患儿气道正常，且无症状。
BLP 似乎是治疗急性 SGS 的有效方法。我们需要更多的研究来完善我们对疗效、安全性和球囊扩张适应证的认识。
