Abstract
We report the outcome of laryngotracheal separation for the treatment of intractable aspiration in eight patients; six children and two adults. The surgical procedures should be adopted depending on whether the patient is a child or adult because of differences in the anatomical stiffness of the trachea. Postoperative pharyngeal-tracheal leakage in one case was treated conservatively for three months and the fistula was closed. As a result, recurrent aspiration subsided in all of the patients. In addition, in some cases of tracheal granulations caused by the canula, the granulations disappeared.
