Objective To explore the method and the clinical effects of surgical treatment for severe hedge brain injury at frontotemporal bottom. Methods 96 patients with severe hedge brain injury at frontotemporal bottom were scored by GOS before surgery. Then unilateral or bilateral craniotomy was carried out,via a large flap incision in the site of frontotemporal and parietal hair,and the blood clots within the surgical fieldand the inactivation brain tissue having been fell off were removed, and the contusion lesions of brain bottom were exposed, and the inactivation brain tissue was cleared. If the brain injury was serious ,the removal of frontal pole and temporal pole should be proper. Discretion to The removing or replacing the bone flap should be based on consideration of the circumstances. Six nonths or one year after injury,96 patients were scored by GOS again. Results There were 17 cases of grade Ⅰ(17.71%) ,11 cases of gradeⅡ (11.46%),13 cases of gradeⅢ (13.54%),21 cases of grade Ⅳ(21.86%),34 cases of grade Ⅴ (35.42%) in 96 patients. Conclusion Early surgical treatment of severe hedge brain injury at frontotemporal bottom could improve the cure rate and reduce the rate of disability.
