|August 1, 1984
Summary
Normal pharyngoesophageal segment function hinders esophageal voice acquisition. For laryngectomized patients, airtight closure during insufflation testing indicates a normal esophageal response, crucial for speech rehabilitation.
Area of Science:
- Speech-Language Pathology
- Otolaryngology
- Voice Rehabilitation
Background:
- Esophageal insufflation testing is used for laryngectomized patients.
- Tracheoesophageal puncture is a common voice restoration method.
Purpose of the Study:
- To assess esophageal voice production in non-laryngectomized individuals.
- To understand the role of pharyngoesophageal segment function in esophageal speech.
Main Methods:
- Fifteen healthy, non-laryngectomized adults underwent standardized esophageal insufflation testing.
- Ability to produce and sustain esophageal voice was documented.
Main Results:
- Normal pharyngoesophageal segment function was found to be detrimental to acquiring functional esophageal voice.
- Laryngectomized patients with airtight pharyngoesophageal closure during testing showed normal esophageal responses.
Conclusions:
- Pharyngoesophageal segment function significantly impacts esophageal voice acquisition.
- Airtight closure during testing is a key indicator for successful voice rehabilitation in laryngectomized patients.
