Laryngotracheal Reconstruction in Children

Abstract

Congenital and acquired subglottic stenosis is a commonly encountered problem in the pediatric population. In acquired cases endotracheal intubation is responsible for its development in the great majority of cases, but high tracheotomy, laryngeal burns, external neck trauma, and tumors, both intrinsic and extrinsic, are occasionally seen. The management of mature subglottic stenosis in children remains a controversial issue. The prevailing attitude of otolaryngologists is to perform a tracheotomy and hope for decannulation after one or two years, due to the expected growth of the larynx. Unfortunately, some of the acquired lesions are so severe that often no lumen is demonstrable. In such cases no amount of growth will allow extubation. A variety of endoscopic methods, such as dilation with or without resection using diathermy or laser, are certainly helpful in the early phases of wound healing while the scar tissue is soft and pliable. To deal with the mature, hard, fibrous, unresponsive scar various authors have proposed differing laryngotracheal reconstructive techniques. The authors discuss a unique experience of laryngotracheal reconstruction in 103 children. They define their indications for the three procedures that are most widely used, and address the issue raised by opponents of laryngotracheal reconstruction in children, namely the consideration that laryngeal growth potential may be adversely affected by such external operations. The authors have evidence that this has not occurred in 35 cases followed for a minimum of five years.
