Abstract
Objective. To assess the outcomes of laryngotracheal reconstruction using thyroid alar cartilage grafting in adult patients with laryngotracheal stenosis.
Study Design. Case series with chart review.
Setting. Tertiary university hospital.
Subjects and Methods. Twelve adults who underwent thyroid alar cartilage graft laryngotracheal reconstruction from April 1997 to April 2009 for laryngotracheal stenosis were analyzed. The mean age of the study population was 29 years. Using the Myer-Cotton grading system, 3 patients had grade II stenosis, 7 had grade III, and 2 had grade IV. Seven of the 12 patients had subglottic stenosis, 3 had tracheal stenosis, and 2 had subglottic and upper tracheal stenosis.
Results. Nine of 12 (75%) patients were decannulated. Of the patients in whom laryngotracheal reconstruction failed, 2 had grade IV stenosis and 1 had severe grade III stenosis with a long segment of stenotic tissue. The postoperative complications were hematoma of the left laryngeal ventricle at the donor site in 1 patient, granulation tissues in the supraglottic and suprastomal region and at the graft site in 4 patients, and neck wound infection in 1 patient. Ossification of the thyroid alar cartilage was observed in 2 patients. A T-tube remained in situ for 6 to 18 months.
Conclusion. Laryngotracheal reconstruction with thyroid alar cartilage graft could be a viable alternative for the treatment of laryngotracheal stenosis in adults. However, it should be used only in cases of limited and minor subglottic or tracheal stenosis.
