Outcomes of Autologous Fat Injection Laryngoplasty in Unilateral Vocal Cord Paralysis.

[INTRODUCTION] Unilateral vocal cord paralysis (UVCP) is not an uncommon finding. Several procedures are available to manage glottal insufficiency. We conducted a clinical trial to evaluate the outcome of fat injection laryngoplasty.

[MATERIALS AND METHODS] Liposuctioned lower abdomen fat was injected for augmentation of paralyzed vocal cord in 20 patients with UVCP. Autologous fat was harvested with an 18G needle and a 20-ml disposable syringe using a liposuction technique. Clinical follow-up after the injection was carried out from 1 to 6-21 months.

[RESULTS] Voice and glottal protective function were significantly improved after the surgery. Vocal elements were immediately improved after the surgery, and after 1 year of follow-up.

[CONCLUSION] Fat injection laryngoplasty by liposuction is simple, safe, effective and has a low cost for patients with UVCP with aspiration and breathy voice dysphonia.
