Outcomes of Autologous Fat Injection Laryngoplasty in Unilateral Vocal Cord Paralysis

Abstract

<strong><em>Introduction</em></strong><strong><em>:</em></strong> <br/>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. <br/><strong><em> </em></strong> <br/><strong><em>Materials and Methods</em></strong><strong><em>: </em></strong><br/>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 <br/><strong><em> </em></strong> <br/><strong><em>Results:</em></strong> <br/>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. <br/><strong><em>Conclusion:</em></strong><em> </em><br/>Fat injection laryngoplasty by liposuction is simple, safe, effective and has a low cost for patients with UVCP with aspiration and breathy voice dysphonia.
