Long-term results of nerve-muscle pedicle reinnervation for laryngeal paralysis.
Between 1976 and 1986, 214 patients with bilateral vocal fold paralysis and 73 patients with unilateral vocal fold paralysis were managed by the author using the nerve-muscle pedicle technique for reinnervation. Follow-up of at least 2 years has been obtained on 202 of the bilaterally and 70 of the unilaterally involved patients. Long-term success has been achieved in 74% of the bilateral group and 88% of the unilateral group. Successful reinnervation of unilateral paralyses usually maintains voice correction indefinitely, but there is late (2 to 5 years postsurgery) deterioration of successful airway restoration in approximately 17% of bilateral cases, which appears to be due to development of cricoarytenoid arthritis.
