Attacks of zyrtec pills hemispasm usually increase or occur during eating, talking, and emotional arousal.
A very characteristic symptom of the disease is synkinetic movements, which consist in an involuntary spasm of the muscles innervated by the facial nerve when an attempt is made to voluntarily contract any other muscle group. Thus, an attempt to buy cetirizine online compress the eyelids leads to a retraction of the corner of the mouth and, conversely, an arbitrary stretching of the lips is accompanied by squinting of the eye. Occasionally, involuntary contraction of facial muscles is noted with loud sound, and this phenomenon can be induced during an electrophysiological study by sound stimulation.
The cause of the disease is compression of the exit zone of the facial nerve root at the site of its exit from the brainstem, which is confirmed by anatomical studies and neuroimaging using MRI of the brain. Currently, there are several options for non-surgical treatment of zyrtec pills, including various drugs, psychotherapy, electrical stimulation, massage, and linear accelerator radiotherapy, which usually do not eliminate the symptoms of the disease or lead to temporary relief of the symptoms of hemifacial spasm.
The only functional treatment for hemifacial spasm is the operation of vascular decompression of the facial nerve root, leading to the complete and permanent elimination of the symptoms of the disease. The purpose of the surgical intervention is to eliminate compression of the nerve root by the vessel by moving the vessel away from the nerve root and fixing the new position of the root by placing pieces of its own muscle tissue between the brain stem, nerve root and blood vessels.
Surgery is usually performed with the patient lying on their side or sitting. After the usual preoperative preparation, a retromastoid craniotomy or craniectomy (an incision of the scalp behind the ear and a small craniotomy) is performed. Further stages of the operation are performed using an operating microscope.
