Unilateral laryngeal recurrent nerve severance, if timely surgery to anastomose the nerve can be restored to the voice, the treatment is not timely will be very difficult to recover, need to be under the guidance of the doctor case-specific treatment.
Laryngeal recurrent nerve severance is often associated with improper operation during surgery. When the laryngeal recurrent nerve is severed unilaterally, there will be hoarseness of the voice, easy choking on drinking water, and weakness of the voice.
If the severed end of the nerve is found to be functioning well within a short period of time, surgery can be attempted to anastomose the severed end of the nerve, thus restoring normal voice.
If one side of the laryngeal recurrent nerve is cut off for too long and cannot be treated by surgery, even if the other side of the laryngeal recurrent nerve is compensated for a long period of time, the normal voice cannot be fully restored, and there will be hoarseness of the voice.
