Summary Objective To evaluate the potential indications of thyroid alar cartilage (TAC) graft in the paediatric laryngotracheal reconstruction (LTR) population based on observations obtained in a case series of 27 consecutive infants referred to our tertiary care center. Methods Thyroid alar cartilage grafting was performed for limited Myer grade II and grade III subglottic stenosis requiring a single-stage laryngoplasty and for laryngeal enlargement after translaryngotracheal resection of endolaryngeal tumors. The evolution of the grafted area was evaluated prospectively during endoscopic follow-up. Results Twenty-five patients (92.5%) were successfully extubated after a mean of 5.1 days. No perioperative or postoperative complications were observed. The mean duration of graft harvesting was 7.7 min. Follow-up of the grafted area revealed one case of partial necrosis without prolapse into the lumen. The mean duration of graft epithelialization was 18.1 days (range: 12–30 days). Development of granulation tissue was observed in eight patients (32%) with a mean duration of granulation tissue persistence of 61.5 days (range: 7–155 days). Endoscopic follow-up did not demonstrate any pharyngolaryngeal asymmetry or feeding difficulties. Conclusion This study demonstrated that the use of thyroid alar cartilage grafting is feasible for pediatric laryngotracheal reconstruction. The indications of thyroid alar cartilage graft should be reserved for moderated subglottic stenosis. The use of TAC reduced the operative time and cosmetic sequelae significantly. The healing of the grafted area was similar to those obtained with other types of graft. The TAC removal did not induce laryngeal deformation but longer follow-up is necessary to confirm this.
