Treated conditions<\/p>\n\n\n\n

Facial Nerve Hemispasm<\/h1>\n\n\n\n

Hemifacial spasm involves unilateral, involuntary, intermittent facial muscle contractions. The facial nerve controls facial expression muscles (forehead, eyes, cheeks, neck). The primary cause is pulsations from a blood vessel contacting the facial nerve at its brainstem emergence.<\/p>\n\n\n\n

Symptoms<\/h2>\n\n\n\n

Symptoms include progressive involuntary facial muscle contractions, often starting around the eyes and spreading. Stress, fatigue, driving, bright lights, TV watching, and reading can exacerbate the condition.<\/p>\n\n\n\n

Diagnosis<\/h2>\n\n\n\n

Brain MRI is indicated to exclude space-occupying lesions and document possible neurovascular conflict.<\/p>\n\n\n\n

Treatment<\/h2>\n\n\n\n

Conservative treatment<\/strong><\/p>\n\n\n\n

Includes oral medication (carbamazepine, phenytoin, baclofen, clonazepam) with limited efficacy and side effects like mental confusion and sedation.<\/p>\n\n\n\n

Botulinum Toxin Injections<\/strong><\/p>\n\n\n\n

The most effective treatment involves injecting botulinum toxin into the affected muscles, providing relief for 3-6 months, with the procedure requiring repetition. Side effects are rare and temporary.<\/p>\n\n\n\n

Surgical Treatment<\/strong><\/p>\n\n\n\n

Microvascular decompression is a surgical method involving separation of the blood vessel from the facial nerve with a foam pad, achieving symptom resolution in over 85% of cases.<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
