[Autoplasty of recurrent laryngeal nerve in the thyroid gland surgery]

Efficacy of autoplasty of recurrent laryngeal nerve (RLN) for laryngeal reinnervation in surgery of differentiated cancer of thyroid gland was studied. Prospectively 8 patients were examined, in whom laryngeal reinnervation, using the RLN autoplasty, for the abduction laryngeal paralysis was done. The examination was performed before and after the operation, it included videolaryngoscopy, acoustic analysis and the patient's self-estimation of psychosocial consequences of the voice-formation disturbance. Improvement of a vocal cords spacious positioning was noted in 38% patients, and was confirmed by trustworthy improvement of the voice-formating parameters after the operation, comparing with a preoperative state. In 72% patients the vocal aperture closure was incomplete and the voice-formation parameters trustworthy differed from such in patients of a control group. When the intact alternative nerves-donors for laryngeal reinnervation are present (distal stump of PLN, ipsilateral and contralateral main branch of cervical loop) the RLN autoplasty performance must be maximally postponed because of low efficacy of such method of surgical laryngeal reinnervation.
