Summary
Voice prostheses significantly improve voice quality and intelligibility in laryngectomized patients compared to esophageal or Servox vibrator voices. Primary tracheoesophageal puncture is recommended for optimal outcomes.
Area of Science:
- Laryngology
- Speech Pathology
- Biomedical Engineering
Background:
- Laryngectomy necessitates alternative voice restoration methods.
- Esophageal voice, Servox vibrator, and voice prostheses are common techniques.
- Assessing voice quality across these methods is crucial for patient care.
Purpose of the Study:
- To compare voice quality in laryngectomized patients using different voice restoration methods.
- To evaluate subjective and objective criteria for voice assessment.
- To determine the optimal method for post-laryngectomy voice rehabilitation.
Main Methods:
- 44 laryngectomized patients were evaluated.
- Voice quality assessed using 13 subjective and 8 objective criteria.
- Patients used esophageal voice, Servox vibrator, or voice prostheses (some with secondary tracheoesophageal punctures).
Main Results:
- Voice prostheses yielded better subjective voice quality.
- Objective measures showed significantly higher maximum phonation times and syllables per air intake with prostheses.
- Prostheses users demonstrated better 'telephone test' intelligibility; primary prostheses had longer phonation times.
Conclusions:
- Voice prostheses offer superior voice quality and intelligibility for laryngectomized patients.
- Primary tracheoesophageal puncture for voice prostheses is supported as the preferred treatment.
- Esophageal voice requires more postoperative rehabilitation compared to prostheses or vibrator use.
