Outline of Final Research Achievements

To evaluate vocal function after nerve-muscle pedicle (NMP) flap implantation with arytenoid adduction (NMP Group, n = 67) compared with type I thyroplasty with arytenoid adduction (Type I Group, n = 12) for patients with unilateral vocal fold paralysis (UVFP). Evaluation of voice range (pitch range and intensity range) and vocal fold vibration (regularity, amplitude, and glottal gap) were performed preoperatively and at two different postoperative periods (short-term: 1-3 months and long-term: > 12 months).
All voice parameters revealed significant improvement postoperatively in both groups. The measurements for pitch range, regularity, amplitude and glottal gap revealed significant improvement between the short- and long-term assessments in the NMP group. The measurements for pitch range and regularity at long-term were significantly favorable compared with the Type I group.
