Six patients with unilateral recurrent nerve paralysis underwent phoniatric follow-up after neurolysis or primary microsurgical repair of the recurrent laryngeal nerve. Four patients were controlled by electromyography of the vocal muscle 14 to 80 months post-operatively. In six patients the paralyzed vocal cords were in median to paramedian position with sustained muscle tonus. Phoniatric parameters were found to be close to the average range in healthy persons. EMG findings indicated degenerative neurogenous paralyses in two patients, signs of reinnervation in another. In one case biphasic action potentials could be recorded.
6例单侧喉返神经麻痹患者在接受喉返神经松解术或初次显微外科修复术后接受了嗓音学随访。4例患者在术后14至80个月接受了声带肌电图检查。6例患者中，麻痹的声带处于中位至旁中位位置，肌肉张力持续存在。嗓音学参数接近健康人的平均范围。肌电图结果显示2例患者为退行性神经源性麻痹，另1例有再支配迹象。1例患者可记录到双相动作电位。
