[Functional and electromyographic long-term results following primary microsurgical repair of the recurrent laryngeal nerve].
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.
