El-Kashlan HK, Carroll WR, Hogikyan ND, Chepeha DB, Kileny PR, Esclamado RM. Selective Cricothyroid Muscle Reinnervation by Muscle-Nerve-Muscle Neurotization. Arch Otolaryngol Head Neck Surg. 2001;127(10):1211–1215. doi:10.1001/archotol.127.10.1211
To determine if selective reinnervation of the cricothyroid muscle could be achieved with muscle-nerve-muscle neurotization.
Tertiary referral center.
Three consecutive patients with high vagal lesions that resulted in unilateral laryngeal paralysis.
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.
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.
The muscle-nerve-muscle neurotization technique was successful in providing selective reinnervation of the cricothyroid muscle in our 3 patients.
