Complication care for patients with facial spasm, surgical treatment of facial spasm is the only curable method. Low cranial pressure headache care, due to the long exposure of the surgical site during surgery, release of large amounts of cerebrospinal fluid, coupled with the stimulation of anesthetics and postoperative intracranial blood leakage, can lead to a decrease in cerebrospinal fluid secretion, resulting in low cranial pressure. The patient developed a headache on the second postoperative day, which lasted for about 1 week, and was given a head-low, foot-high position, advised to drink more light saline and eat salty food. After the above treatment, the patient’s symptoms resolved and he was discharged without recurrence after follow-up. Peripheral facial palsy During microvascular decompression surgery, damage to the facial nerve is often related to direct injury and excessive stretching during the surgery. Facial palsy appeared in the postoperative period and was classified as mild facial palsy. The nursing staff explains to the patient well and informs him that facial palsy usually recovers on its own. The patient’s eyelid could not be closed due to facial palsy, so he was given topical application of gentamycin eye ointment and Vaseline gauze to cover the eye on the side of facial palsy and gauze during sleep to protect the cornea and prevent the occurrence of keratitis, and the eyelid could be closed after 1 week. Do circular massage on the paralyzed facial muscles 3 to 4 times a day for 15min a 20min each time to promote blood circulation. When the nerve function starts to recover, encourage the patient to practice functional exercises such as opening mouth, cheek puffing and balloon blowing to prevent muscle atrophy. The diet should be hot and cold, eat on the healthy side as much as possible, and chew slowly when eating to prevent bites and ulcers, and rinse the mouth after each meal to avoid food residues being retained in the oral cavity on the facial palsy side. Patients recover completely within 1 month. Hearing impairment Hearing impairment is a more common complication after MVD surgery, mainly manifested as ipsilateral hearing loss or deafness. It occurs due to intraoperative injury to the auditory nerve or the trophoblastic vessels of the auditory nerve. The main cause of injury is the prolonged strain on the cerebellar hemispheres, which causes the auditory nerve to be under high tension for a long time. The hearing loss appeared on the 5th postoperative day. The nursing staff patiently explained to the patient the reasons for the hearing loss, comforted the patient, and eliminated his nervousness. Usually, the patient spoke in the patient’s healthy ear and avoided loud shouting. After six months of follow-up, the patient’s hearing recovered in about 6 months.
