Facial nerve decompression surgery is usually referred to as microvascular decompression and is primarily performed to treat facial muscle spasm. The general procedure is performed with the patient under general anesthesia, sterile towels are placed in the appropriate position, and the surgical incision is drawn. In the next step, the scalp is incised to form a bone window, which is usually about 3-4 cm in size. the upper edge reaches the transverse sinus and the anterior edge reaches the edge of the sigmoid sinus, the dura is incised and separated layer by layer to reach the facial nerve, the relationship between the facial nerve and the surrounding tissues is searched for, the vessels compressing the facial nerve are cushioned with special materials, and finally the skull is closed layer by layer. The operation is performed gently to avoid damage to brain tissue and nerves. Postoperative dynamic review of the head CT is required to evaluate the surgical results.
