title: Esophageal insufflation testing in nonlaryngectomized adults.
abstract: Esophageal insufflation testing has been advocated for laryngectomized patients considered for tracheoesophageal puncture. The present work was undertaken to document the degree to which nonlaryngectomized individuals were able to produce and sustain esophageal voice in association with esophageal insufflation testing. Fifteen young, healthy adults were tested in a uniform way. Results were interpreted to support the views that (a) normal function of the pharyngoesophageal segment represents an influence detrimental to the ultimate acquisition of functionally serviceable esophageal or tracheoesophageal speech and (b) laryngectomized patients having airtight closure of the pharyngoesophageal segment during insufflation testing exhibit a normal esophageal response. Implications for completing air insufflation testing and selective myotomy are discussed.
