Introduction
声带一边不动可能是声带疲劳、声带结节、声带神经麻痹、帕金森病、先天性发育异常等引起的，可根据不同的情况进行处理。声带的Exercise由喉返神经控制，当喉返神经受损或受压迫时，会导致声带Exercise受限或完全停止。Recommendation及时就医Examination，明确Cause后对症处理。
Immobility of one side of the vocal cords may be caused by vocal fatigue, vocal cord nodules, vocal cord paralysis, Parkinson's disease, congenital developmental abnormalities, and other conditions, and should be managed according to the specific cause. Detailed analysis is as follows:
1. Vocal fatigue: Prolonged or intense voice use can lead to fatigue of the vocal cord muscles, resulting in restricted movement of one vocal cord. It is recommended to rest the voice appropriately, avoid overuse, drink plenty of water, and engage in voice training and rehabilitation exercises.
2. Vocal cord nodules: Long-term, high-intensity speaking may cause nodules to form along the edges of the vocal cords, affecting their normal vibration and leading to immobility of one vocal cord. Small polyps or nodules may be treated conservatively with voice therapy and rehabilitation exercises.
3. Vocal cord paralysis: Movement of the vocal cords is controlled by the recurrent laryngeal nerve. Damage or compression of this nerve can result in restricted or complete loss of vocal cord movement. It is recommended to follow medical advice and take medications such as vitamin B1 tablets, mecobalamin tablets, and oryzanol tablets to promote nerve recovery.
4. Parkinson’s disease: Neurodegenerative changes in Parkinson’s disease reduce neurotransmitters such as dopamine, impairing neural signal transmission—including signals controlling vocal cord movement—leading to weakened or lost vocal cord motion. It is recommended to follow medical guidance in using medications such as trihexyphenidyl hydrochloride tablets, amantadine hydrochloride tablets, and levodopa tablets to relieve symptoms.
5. Congenital developmental abnormalities: During embryonic development, incomplete or abnormal development of the vocal cords or the nerves that control them can lead to impaired vocal cord function. Unilateral vocal cord paralysis due to congenital abnormalities may require surgical correction or speech therapy to improve vocal cord function.
If any abnormality of the vocal cords occurs, it is advisable to seek timely medical evaluation to determine the underlying cause and receive appropriate treatment.
