Laryngotracheal separation through the cricoid ring for management of tracheobronchomegaly.

Tracheobronchomegaly is a rare condition characterized by diffuse dilation of the trachea and main bronchi. In ventilator-dependent neonates with tracheobronchomegaly, a tracheostomy may be hazardous due to the lack of an appropriate tracheostomy tube size that can fit the enlarged trachea. Here, we describe a modification of the laryngotracheal separation procedure to permit ventilation in a child with tracheobronchomegaly and severe bronchopulmonary dysplasia.
