Abstract
Breakdown of the normal protective function of the larynx, either through primary laryngologic or neurologic causes, leads to chronic aspiration, recurrent pneumonitis and possibly death. In this paper we discuss the existing surgical treatments for chronic aspiration. Tracheal separation and trechcocsophageal diversion are discussed, as are the difficulties of using these procedures in patients with pre-existing tracheostomies. A modification of trachcoesophageal diversion is presented whereby this procedure can now be utilized in those patients with pre-existing tracheostomies. The modified tracheoesophageal diversion is performed in five patients successfully. Since most patients have already had tracheotomies in an attempt to control aspiration, we feel that our technique of modified trachcoesophageal diversion enables this group of patients to benefit from this procedure as well.
