[Repair of recurrent laryngeal nerve injuries after thyroidectomy]
1Department of Otolaryngology, Changhai Hospital, Second Military Medical University, Shanghai, P. R. China 200433.
Objective:
In order to investigate the opportunity of repair and prognosis of recurrent laryngeal nerve injuries after thyroidectomy.
Methods:
Twelve cases with recurrent laryngeal nerve injuries after thyroidectomy were immediately and delayed operated on nerve repair and reinnervation. In immediate operation, 5 cases were repaired by direct recurrent laryngeal nerve suture, and 1 case was treated by transposition of the phrenic nerve to the recurrent laryngeal nerve and sutured the adductor branch to the branch of ansa cervicalis. In delayed operation, 3 cases were treated by anastomosis the main trunk of ansa cervicalis to the adductor branch of recurrent laryngeal nerve, and 3 cases were operated on neuromuscular pedicle to reinnervate posterior cricoarytenoid muscle.
Results:
Followed up 6 months, the effect was excellent in 1 case who was immediately operated by selective reinnervation of the abductor and adductor muscles of the larynx, better in 9 cases, and poor in 2 cases who were delayed operated over 12 months.
Conclusion:
It can be concluded that the earlier reinnervation is performed, the better prognosis is.
