A guided approach to surgery for aspiration: two case reports.

Aspiration frequently occurs in patients with a competent glottis. Analysis using a modified barium swallow (MBS) can reveal an extraglottic mechanism of aspiration in these patients. The MBS examination guided the design of two surgical procedures in patients with severe aspiration. The surgery corrected the underlying extraglottic cause of aspiration while preserving glottic function. In one case the epiglottoplasty controlled aspiration due to spillage over the epiglottis into the airway. In the other case translaryngeal resection of the cricoid lamina combined with cricopharyngeal myotomy controlled aspiration of residue in the hypopharynx. After surgery, both patients had their gastrostomy and cuffed tracheostomy tubes removed and were discharged home on a normal oral diet. Detailed analysis of deglutition by a modified barium swallow can provide a scientific basis to guide the surgical management of patients with severe dysphagia.
