Abstract: Background: The term "laryngotrachealstenosis" (LTS) refers to the partial or total constriction of the trachea or endolarynx. High morbidity and recalcitrance characterize LTS. The present study was conducted to assess balloon dilation laryngoplasty for acquired subglottic stenosis.

Materials & Methods: 56 cases of airway stenosis of both genders were selected. Etiology of stenosis, number and frequency of dilations, and interval between tracheostomy and decanulation were recorded.

Results: Out of 56 patients, 30 were males and 26 were females. Diagnosis was Post Rta in 23, post intubation in 17, Op posion in 8 and post acid ingestion in 6 cases. Grade 1 was seen in 14, grade 2 in 34 and grade 3 in 8 cases. Length of stenosis was 1-3 mm in 17, 4-7 mm in 24 and 8-10 mm in 15 cases. Interval of balloon dilation was 1-2 weeks in 31 and 2-4 weeks in 25 patients. The difference was significant (P< 0.05).

Conclusion: Balloon dilations are safe and efficient in thetreatment of subglotticstenosis and reducesthe need for open laryngeal surgery.
