Endoscopic surgical treatment of laryngotracheal clefts: indications and limitations.

OBJECTIVE

To present the indications, techniques, results, and limitations of endoscopic surgical treatment of laryngotracheal cleft.

DESIGN

Retrospective case note study (2005-2009).

SETTING

Department of Otolaryngology-Head and Neck Surgery, Armand Trousseau Children's Hospital, Paris, France.

PATIENTS: Eleven patients who underwent endoscopic cleft closure as a primary (n = 8) or secondary (n = 3) procedure among 22 patients treated for laryngotracheal clefts. We report patients' demographics, symptoms leading to the diagnosis, endoscopic evaluation method, medical examination results, and surgical techniques.

INTERVENTION: Endoscopic closure of the cleft under spontaneous ventilation via 2-layer interrupted sutures after excision of the mucosal edge using a carbon dioxide laser in 10 patients and a thulium laser in 1.

MAIN OUTCOME MEASURES: Analysis of postoperative complications, revision surgery, need for intensive care unit admission, closure of the cleft, and long-term symptom results.

RESULTS

Successful closure of the 11 clefts (with revision surgery in 3 patients) without the need for intubation or intensive care unit admission enabled the elimination of aspiration in 10 patients and significant improvement in 1 patient with bilateral vocal cord paralysis. There were no significant postoperative complications.

CONCLUSIONS

Endoscopic closure of laryngotracheal clefts is a reliable technique that significantly reduces perioperative and postoperative morbidity. The results of this technique are entirely satisfactory, and we suggest that it is suitable as a primary procedure for the treatment of type I, II, and III clefts extending to the cervical trachea, including in neonates.
