Patient: I feel that my voice is hoarse and intermittent, and I feel like it is blocked, but I feel more normal when I change my breath. Last year, I was hospitalized in 301 and diagnosed with spasmodic dysphonia. There are no treatment measures. The doctor said that it is the mildest symptom and can be recovered, just relax. I have been suffering from the disease for a year now, and I am a high school teacher. I have been drinking Chinese herbal medicine for a period of time to replenish my qi and blood. Xu Wen, Department of Otolaryngology, Beijing Tongren Hospital: First of all, we need to consult the neurology department to exclude the central disease caused by pronunciation tremors, and we also need to consult the psychology department to exclude the functional dysphonia caused by psychological factors. On the basis of this, we should conduct laryngeal electromyography to determine whether the laryngeal muscles are hyperfunctional. If the laryngeal electromyography is more hyperactive than normal, local injection of botulinum toxin is needed.
