✦ Synopsis

Investigation of postlaryngectomy dysphagia is usually limited to the standard barium swallow. Manofluorography (mano, manometry; fluom, videofluoroscopy; graphy, picture) is a new technique that permits analysis of simultaneous manometry and videofluoroscopy of deglutition. Manofluorography provides more detailed analysis of the swallowing dynamics during the pharyngeal stage of deglutition than either barium studies or manometry used alone. This study uses manofluorography to examine swallowing in two patient groups, total laryngectomees and total laryngectomees with tongue impairment, to analyze the role of various anatomic components in the swallowing process. Pharyngeal transit times were prolonged in both patient groups studied, with the tongue impairment group exhibiting the longest times. The postlaryngectomy pharynx offered greater resistance to bolus flow.

The laryngectomy patients compensated by using increased lingual propulsion, whereas the patients with tongue impairment and total laryngectomy could not. This emphasizes the importance of the tongue in bolus propulsion in the pharynx. Other postoperative changes in swallowing are discussed. HEAD & NECK SURGERY 9:3-12,1986
