Abstract:
Objective To investigate the necessity of primary neurorrhaphy (direct end-to-end anastomosis) when the recurrent laryngeal nerve(RLN) is severed during thyroid surgery.Methods 15 patients who suffered from iaotmgenic unilateral complete RLN injury or whose unilateral RLN had to be sacrificed because of disease invasion had a primary repair of RLN by direct end-to-end anastomosis.In control group,26 patients who did not have a nerve repair were enrolled into this study.Subjective evaluation of aspiration and voice quality were based on patient reports and hearer reports for all patients.9 patients with neurorrhaphy and 12 patients without nerve repair were followed with videolaryngoscopic examination.Results 14 patients undergoing neurorrhaphy restored normal voice at 2-5 months postoperatively.Although there were no significant functional motion of the vocal fold,slight adductory movement of the affected arytenoid was found with good tension vocal cords and symmetric arytenoids of the glottis during phonation.Only 2 patients without nerve repair had nearly restored normal voice.The patients with hoarseness had stiff arytenoids and atrophic folds resulting in glottal gap.Conclusions Neurorrhaphy is a simple and effective method to restore the normal aspiration and voice quality of patients with unilateral complete recurrent laryngeal nerve injuries.
