Arytenoid adduction combined with nerve-muscle pedicle flap implantation or type I thyroplasty.
Laryngoscope. 2017 01; 127(1):159-166.L

Abstract

OBJECTIVES/HYPOTHESIS

To evaluate vocal function after refined nerve-muscle pedicle (NMP) flap implantation with arytenoid adduction (AA) compared with type I thyroplasty with AA for patients with unilateral vocal fold paralysis (UVFP) and to evaluate the degree of patient satisfaction following the refined NMP with AA.

STUDY DESIGN

A retrospective review of clinical records of 52 patients with UVFP who received AA + NMP (NMP group, n = 40) or AA + type I thyroplasty (type I group, n = 12) as a single-stage operation between April 1999 and December 2011.

METHODS

Evaluation of vocal fold vibration, aerodynamic analysis, perceptual evaluation, acoustic analysis, and subjective assessment were performed preoperatively and at two different postoperative periods (short term: within 3 months and long term: >12 months).

RESULTS

All parameters except for glottal gap of the vocal fold vibration, maximum phonation time (MPT), and mean airflow rate revealed significant improvement between the short- and long-term assessments in the NMP group. On the contrary, the type I group did not show significant change of any parameters during postoperative periods. In the NMP group, the measurements for regularity of the vocal fold vibration and MPT at the long-term assessment were significantly favorable compared with the type I group. In the NMP group, subjective assessment (Voice Handicap Index-10 and Voice-Related Quality of Life) revealed significant improvement between the short- and long-term assessments.

CONCLUSIONS

In comparison with the type I group, significant improvement of vocal function patient satisfaction during the long-term follow-up period after AA combined with the refined NMP was confirmed.
