About this book


All laryngologists, especially general ENT doctors for patients with paralytic dysphonia, as well as speech pathologists, will benefit from this book’s coverage of basic and clinical aspects of reinnervation in retrieving patients’ normal voices.

Phonosurgical treatment for paralytic dysphonia was established in the late 1970s as arytenoid adduction and medialization laryngoplasty. It has recently been established that immediate reconstruction of the recurrent laryngeal nerve during tumor extirpation is effective in recovery of original voices in patients with unilateral vocal fold paralysis (VFP). The activity of the thyroarytenoid muscle is needed to recover normal voices. Nerve–muscle pedicle (NMP) flap implantation with a refined technique to the thyroarytenoid muscle is a novel method for that purpose. NMP flap implantation with arytenoid adduction was applied by the author to patients with dysphonia, and most of them recovered their nearly normal voices after surgery.

This book provides readers with (1) currently prevalent surgical procedures, (2) unsatisfactory results of conventional procedures, (3) results of immediate recurrent laryngeal nerve reconstruction during tumor extirpation, (4) outcomes of delayed reinnervation combined with arytenoid adduction in patients with VFP, and (5) the scientific basis explaining why the author’s method is effective in the recovery of patients’ own pre-paralysis, normal voices.
