Total Versus Partial Arytenoidectomy in Bilateral Vocal Fold Paralysis
Study Details
Study Description
Brief Summary
Total arytenoidectomy is claimed to increase risk of aspiration and cause more voice loss than other operations performed for bilateral vocal fold paralysis (BVFP). However, objective evidence for such conclusion is lacking. There is no study comparing swallowing and voice after total and partial arytenoidectomy.

Outcome Measures
Primary Outcome Measures
- Decannulation [From the day of operation until 52 weeks after arytenoidectomy]
Preoperative examinations were repeated 1 year after surgery.
Secondary Outcome Measures
- Duration of operation [At the day of operation]
The duration of operation was measured in minutes at the day of operation.
Other Outcome Measures
- Voice Handicap Index [From the day of operation until 52 weeks after arytenoidectomy]
Voice Handicap Index is a 30-item questionnaire. Possible points change between 0 to 120. Zero means normal voice, 120 means the worst voice. Preoperative examinations were repeated 1 year after surgery.
- Acoustic analysis [From the day operation until 52 weeks after arytenoidectomy]
Fundamental frequency (Hertz), absolute jitter (microseconds), shimmer percent (%), noise to harmonic ratio will be measured as physical measures of voice.
- Aerodynamic analysis [From the day of operation until 52 weeks after arytenoidectomy]
Maximum phonation time (seconds), mean flow rate (liters/second), mean resistance (cmH20/liter/second), mean power (Watt), mean efficiency (ppm) and mean pressure (cmH2O)are obtained as physical measures of aerodynamic analysis.
- Postoperative breathing ability [52 weeks after arytenoidectomy]
Breathing ability was evaluated on a scale of -2 to +2 (-2: significantly worse; -1: somewhat worse; 0: no change; +1: somewhat better; +2: significantly better).
- Subjective comparison of pre- and postoperative voice by a phoniatrician [From the day of operation until 52 weeks after arytenoidectomy]
Subjective comparison of pre- and postoperative voice on a scale of -2 to +2 (-2: significantly worse; -1: somewhat worse; 0: no change; +1: somewhat better; +2: significantly better).
- Speech intensity [52 weeks after arytenoidectomy]
Speech intensity is measured in decibels.
- Functional outcome swallowing scale [52 weeks after arytenoidectomy]
Functional Outcome Swallowing Scale: 0-5 (0: Normal function and asymptomatic; 1: Normal function with episodic or daily symptoms of dysphagia; 2: Compensated abnormal function manifested by significant dietary modifications or prolonged mealtime (without weight loss or aspiration); 3: Decompensated abnormal function with weight loss of <10% of body weight over 6 months due to dysphagia; or daily cough, gagging or aspiration during meals; 4: Severely decompensated abnormal function with weight loss of >10% of body weight over 6 months due to dysphagia; or severe aspiration with bronchopulmonary complications. Non oral feeding for most nutrition; 5: Non oral feeding for all nutrition).
