The purpose of this presentation is to review our current approach to selective modification of micro anatomy of laryngeal neuromuscular function.
Dissection of the distal micro-branches of the recurrent laryngeal nerve allows for selective modification of laryngeal adductory and abductory function.
The surgical techniques for identification of recurrent laryngeal nerve branches to the posterior cricoarytenoid muscle, the lateral cricoarytenoid muscle, and the vocalis muscle are described. Alteration of function is achieved using motor branches of the ansa hypoglossi nerve or the superior laryngeal nerve for reinnervation. The techniques described are useful for the treatment of a variety of disorders such as spasmodic dysphonia or laryngeal unilateral and bilateral paralysis.
