Selective cricothyroid muscle reinnervation by muscle-nerve-muscle neurotization.

Academic Article

Abstract

  • OBJECTIVE: To determine if selective reinnervation of the cricothyroid muscle could be achieved with muscle-nerve-muscle neurotization. DESIGN: Case series. SETTING: Tertiary referral center. PATIENTS: Three consecutive patients with high vagal lesions that resulted in unilateral laryngeal paralysis. INTERVENTIONS: Patients underwent laryngeal reinnervation with ansa hypoglossi to recurrent laryngeal nerve anastomosis. In addition, patients underwent selective cricothyroid muscle reinnervation by muscle-nerve-muscle neurotization technique. MAIN OUTCOME MEASURES: Objective and subjective improvement in voice quality and electromyographic evidence of selective reinnervation of the cricothyroid muscle. RESULTS: All patients recovered normal or near-normal speaking voice and had normal objective measures of voice quality. They also showed electromyographic evidence of cricothyroid muscle reinnervation. CONCLUSION: The muscle-nerve-muscle neurotization technique was successful in providing selective reinnervation of the cricothyroid muscle in our 3 patients.
