Swallowing disorders in three types of head and neck surgical patients.

This study examined swallowing transit times and motility problems in three groups of patients following ablative surgery for oropharyngeal carcinoma and in a control group of 10 normal subjects. A total of 30 patients was studied: 10 after anterior floor of mouth resection, 12 after tonsil/base of tongue resection, and 8 after supraglottic laryngectomy. Videofluoroscopic studies of liquid, thin paste, thick paste, and thick paste plus liquid swallows were completed 1 week post-initiation of oral feeding following surgery. From the videotapes, oral and pharyngeal transit times were measured, and motility disturbances were defined during each stage of the swallow. All three types of patients in this study showed severe problems with swallowing. The anterior floor of mouth resection patients had problems with preparation for the swallow and oral transit. Tonsil/base of tongue resection patients had slowing in the preparation for the swallow and in the oral and pharyngeal stages. After supraglottic laryngectomy, patients showed only slight slowing in oral transit and pharyngeal transit as compared to other types of surgical patients.
