Slide tracheoplasty applied to acquired subglottic and upper tracheal stenosis: an experimental study in a canine model.

Objective: To assess the applicability and complications of slide tracheoplasty in the management of subglottic and upper tracheal stenosis in experimental animals.

Design: Subglottic stenosis was induced in 10 dogs by cauterizing the subglottic area and the upper 3 to 4 cm of the trachea. After 21 days, the severity of stenosis ranged from 30% to 60%.
