Nonselective reinnervation as a primary or salvage treatment of unilateral vocal fold palsy
The Laryngoscope Oct 24, 2019
Marie JP, et al. - In patients with strong denervation proven by laryngeal electromyography (LEMG), researchers conducted this prospective cohort study to illustrate improvement and long-term stability of voice following nonselective reinnervation performed as a primary or secondary treatment of unilateral vocal fold paralysis (UVFP), as well as to demonstrate further voice improvement after time surpassing direct voice improvement due to fat augmentation attributable to axonal regrowth. In all patients, they performed the ansa cervicalis–recurrent laryngeal nerve anastomosis technique. Before and 1 year after unilateral laryngeal reinnervation (ULR), LEMG and spirometry were performed. For patients with high expectations concerning voice quality, nonselective ULR in UVFP is a reliable and stable therapeutic option. The effect in long-term outcomes is stable. It is also a viable option for patients who have failed to improve voice quality by conventional voice surgery. Therefore, ULR as a salvage option in UVFP was proposed.
