Results of ansa to recurrent laryngeal nerve reinnervation

Abstract

Ansa-RLN reinnervation should be considered as a treatment for unilateral vocal fold paralysis.

A novel modification of the ansa to recurrent laryngeal nerve reinnervation procedure for young children

“…Furthermore, reinnervation does not alter the laryngeal skeleton and has no potential to alter the way the skeleton grows in the future. It also preserves the possibility of other laryngoplasty techniques in the future, should any more surgery be necessary [8].…”

“…The disadvantages of this technique are delayed time to voice improvement, requirement of an intact donor and recipient nerve, and sacrifice of the natural course at the ansa and recurrent laryngeal nerve [8].…”

Ansa-RLN reinnervation for unilateral vocal fold paralysis in adolescents and young adults

“…The ansa-RLN procedure was first described in the 1920s, and re-introduced by Crumley and Izdebski [16]. Several other studies have detailed the voice outcomes of this procedure that document its effectiveness in treating dysphonia from unilateral vocal fold paralysis, however very few have reported outcomes in adolescents and young adults [10,15,17,18]. In an updated large case series of ansa-RLN reinnervation procedure in 46 patients with unilateral vocal fold paralysis, the youngest patient was 22 years of age, and the average age was 53 years [19].…”

Non-Selective Laryngeal Reinnervation for Unilateral Vocal Fold Paralysis

“…Disadvantages of this technique are the requirement of a general anaesthetic, voice improvement is not immediate, requirement of an intact nerve donor and recipient and a suggestion of increased probability of delayed or failed reinnervation in older patients (18). Although the effect of reinnervation is delayed up to 4 months, the problems of aspiration and hoarseness may be assisted temporarily by bulking up the vocal fold with absorbable injectable substances-injection laryngoplasty.…”

“…Although the effect of reinnervation is delayed up to 4 months, the problems of aspiration and hoarseness may be assisted temporarily by bulking up the vocal fold with absorbable injectable substances-injection laryngoplasty. Concomitant injection laryngoplasty using absorbable material may give immediate improvement, strengthening the voice during this waiting period (19).…”
