Whether this kind of operation is suitable or not depends on the patient's specific situation: (1) If the depressed part of the skull is only 3 cm, this part is protected by temporal muscle, and the elderly have less exercise and less possibility of re-trauma, so there is always a certain risk in the operation, and skull repair surgery is unnecessary. (2) The head circumference of children under 5 years old grows rapidly, so skull repair is not recommended for children under 5 years old. The head circumference of children under 5 ~ 10 years old grows slowly and can be repaired.

Routine infection prevention treatment was performed after operation, the drainage tube was removed after 24 hours, and the stitches were removed 7 ~ 9d days after operation. Significance of temporal muscle tissue reconstruction: tissue reconstruction is particularly important in skull defect reconstruction, and special attention should be paid to reconstructing physiological tissue structure. Intermittent suture of temporalis myofascia and muscle from the outside of titanium mesh can prevent postoperative complications such as masticatory weakness, pain and appearance deformation, which is conducive to physiological repair as soon as possible after operation and enable patients to live a normal life as soon as possible. Temporal muscle tissue reconstruction group: titanium mesh was fixed, temporalis myofascia and muscle were attached to the surface of titanium mesh in a fan shape, and temporalis myofascia and muscle were sutured to the surface of titanium mesh intermittently; Ordinary surgical repair method: flip flap, that is, temporalis myofascial skin flap, is used to expose bone defect area, cover titanium mesh, and directly cover all temporalis muscles under titanium mesh. Results: 86 patients were followed up for 65438 0 months to 6 years. ① Patients with temporalis muscle tissue architecture have strong masticatory function, mild head and face pain, no obvious atrophy of temporalis muscle and no or slight skin depression. These are the suggestions on the causes of skull depression just after a month of skull repair surgery. I hope it helps you, and I wish you health!
