Abstract
Background: The recurrent laryngeal nerve and the superior laryngeal nerve are branches of the vagus nerve. The superior laryngeal nerve (external branch) innervates the cricothyroid muscle, which tenses and adducts the vocal folds. Injury to the nerve can produce changes in voice quality, but is generally not dangerous. Injury to the recurrent laryngeal nerve is of more consequence, as it innervates all of the intrinsic muscles of the larynx, except for the cricothyroid muscle which is innervated by the superior laryngeal nerve. A unilateral recurrent laryngeal nerve injury produces abductor vocal cord paralysis, so the affected cord assumes a Para median position which causes postoperative hoarseness. Bilateral vocal fold paralysis, on the other hand, can manifest as partial vs. complete airway obstruction Aim of this study: This study was conducted to show the effect of unilateral suture lateralization in management of bilateral vocal fold paralysis on respiration, phonation and swallowing in patients with respiratory distress and to precisely describe the exact location of suture lateralization to maximize the benefits and decrease the risk of endolaryngeal soft tissue injury. Method: A Prospective cross sectional intervention study with analytic component was approved by the institutional research board of Mansoura University. This study was conducted on a sample of (19) Egyptian patients suffering from bilateral vocal fold paralysis admitted to otorhinolaryngology department, Mansoura university hospitals within 2-years duration (from May 2019 to June 2020). Results: Suture lateralization of vocal fold is a very important procedure in the management of bilateral vocal fold paralysis, endoscopic suture lateralization should be considered for all patients with bilateral vocal fold paralysis, especially in cases with good prognosis for recovery. It represents a reversible, minimally invasive, and possibly immediate alternative not only to tracheostomy but also for destructive ablative procedures such as cordectomy. Conclusion Endoscopic suture lateralization could be considered for all patients with bilateral vocal fold paralysis, especially in cases with good prognosis for recovery. It represents a reversible, minimally invasive0, and possibly immediate alternative not only to tracheostomy but also for destructive ablative procedures such as cordectomy.
