An improved esophageal insufflation test
E. D. Blom, M. I. Singer and R. C. Hamaker
Previous investigations identified that insufflation of the esophagus may
elicit reflex pharyngoesophageal closure, impeding airflow and subsequent
voice production. A simplified method for esophageal insufflation
consistently evaluates the capacity for alaryngeal speech acquisition.
Although primarily a method for predicting tracheoesophageal speech, it may
also be an important prognostic indicator for traditional esophageal speech
development.
