چکیده
OBJECTIVE We sought to describe the results of ansa cervicalis to recurrent laryngeal nerve (ansa-RLN) reinnervation for unilateral vocal fold paralysis. STUDY DESIGN A chart review was performed on patients undergoing ansa-RLN reinnervation for unilateral vocal cord paralysis at a tertiary care center. Patient perceptions of preoperative and postoperative voice quality was surveyed. Acoustic and visual parameters were assessed from videostroboscopy. RESULTS From a total of 25 study patients, 15 patients underwent both preoperative and postoperativ video stroboscopies. In stroboscopies within 6 months, the average improvement in overall severity, roughness, and breathiness was 69, 79, and 100 percent, respectively. In stroboscopies after 6 months, the average improvement in overall severity, roughness, and breathiness was 63, 66, and 100 percent, respectively. Postoperatively, all patients had reinnervation of the vocal fold. CONCLUSIONS Voice outcomes were improved in patients with preoperative and postoperative stroboscopies. SIGNIFICANCE Ansa-RLN reinnervation should be considered as a treatment for unilateral vocal fold paralysis.

Laryngeal reinnervation for unilateral vocal fold paralysis using ansa cervicalis nerve to recurrent laryngeal nerve anastomosis
In laryngeal paralysis, the stiffness of the denervated vocal fold is decreased. This leads to deviant vibratory patterns involving 2 asymmetric vocal folds and results in abnormal vocal quality. Follow-up studies of medialization thyroplasty patients have noted that decrement in vocal quality after medialization is often because of continuing vocal fold atrophy. Vocal cord atrophy from denerva...
متن کاملLaryngeal reinnervation by ansa cervicalis nerve implantation for unilateral vocal cord paralysis in humans.
BACKGROUND Ansa cervicalis (AC)-recurrent laryngeal nerve anastomosis (RLN) is usually not desirable for correction of paralytic dysphonia when it is difficult to find a viable distal stump of the recurrent laryngeal nerve. Nerve implantation of the thyroarytenoid muscle with the ansa cervicalis is a simple alternative method. STUDY DESIGN Ten patients with unilateral vocal cord paralysis wer...
متن کاملEffect of duration of denervation on outcomes of ansa-recurrent laryngeal nerve reinnervation.
OBJECTIVES/HYPOTHESIS To investigate the efficacy of laryngeal reinnervation with ansa cervicalis among unilateral vocal fold paralysis (UVFP) patients with different denervation durations. STUDY DESIGN We retrospectively reviewed 349 consecutive UVFP cases of delayed ansa cervicalis to the recurrent laryngeal nerve (RLN) anastomosis. Potential influencing factors were analyzed in multivariab...
متن کاملFunctional reinnervation of vocal folds after selective laryngeal adductor denervation-reinnervation surgery for spasmodic dysphonia.
Selective laryngeal adductor denervation-reinnervation surgery (SLAD-R) offers a viable surgical alternative for patients with adductor spasmodic dysphonia refractory to botulinum toxin injections. SLAD-R selectively denervates the symptomatic thyroarytenoid muscle by dividing the distal adductor branch of the recurrent laryngeal nerve (RLN), and preventing reinnervation, by the proximal RLN an...
متن کاملAnatomical study of the human ansa cervicalis nerve and its variations
With the expanding use of the ansa cervicalis nerve for laryngeal reinnervation procedures. So the aim of this work was to study the anatomical variations of ansa cervicalis in its roots, course and branching pattern. Twenty five Egyptian necks (50 sides) were dissected. The results showed that the ansa cervicalis (AC) consisted of two roots: superior and inferior roots. These two roots joined ...
