title: Relation between videofluoroscopy of the esophagus and the quality of esophageal speech.
abstract: The goal of the current study was to compare the quality of esophageal speech and voice to videofluoroscopic features of the esophagus and pharyngoesophageal (PE) segment. The speech and voice characteristics of 30 laryngectomized patients were rated by 5 speech-language pathologists. Based on these ratings, patients were divided into 3 categories: fluent (n = 9), moderately fluent (n = 10) and nonfluent (n = 11). Videofluoroscopy of the PE region was then performed during both swallowing and voice production. An insufflation test and percutaneous pharyngeal plexus block were required in 9 patients to determine the etiology of poor esophageal voice production. The strongest videofluoroscopic indicators of nonfluent speakers were: (1) small or absent air reservoir and (2) lack of a vibrating PE segment. Fluent speakers presented with shorter PE segments (1.17 mm) compared to moderately fluent speakers (17.1-29.9 mm). Perceptually, fluent speakers presented with a predominantly rough vocal quality. In contrast, moderately fluent speakers presented with a tense quality. In addition, stoma blast noise was reduced in fluent speakers. Videofluoroscopic findings highly correlated with the quality of esophageal speech.
