    In case of BVFP, Botox may be used to block aberrant reinnervation of the adductor muscles by inspiratory motoneurons. These cells survived and were incorporated into the muscle alongside atrophying fibers at 2 months. Type A and B are the forms most frequently used clinically. Reinnervation using ansa cervicalis nerve-muscle pedicle transfer or phrenic nerve transfer to posterior cricoarytenoid muscle can be done.
