Application of a Grading System in the Treatment of Frontal Lobe Contusion in High-Altitude Regions

OBJECTIVE: With the development of frontal contusion, patients may rapidly deteriorate or even die. Experience in the treatment of frontal contusion in high-altitude regions is limited; thus, we explore a grading system for the treatment of frontal lobe contusion. METHODS: A total of 446 patients with frontal contusions in a high-altitude regions were reviewed retrospectively. We combined the patients' computed tomography scans of the head and clinical features for grading. The score determined the treatment and whether the bone flap was removed. If the patient's condition deteriorated, and the score was greater than 1, the patient was treated surgically. At the same time, the risk factors of deterioration were analyzed. Finally, the Glasgow Outcome Scale of conservative treatment and surgical treatment groups was analyzed. RESULTS: Among the 446 patients, 254 were conservatively treated, and 28 worsened and underwent surgical treatment. In total, 122 patients received an operation. Logistic regression analysis indicated that scattered hematoma, anterior angle of the ventricle, and hemoglobin concentration were risk factors. The postoperative Glasgow Outcome Scale of conservative treatment and surgical treatment groups was analyzed; the good healing rate of the conservative treatment group was 91.12%, the good healing rate of the retain-bone flap surgical group was 75%, and the good healing rate of the remove-bone flap surgical group was 63.33%. The failure rates of the groups were 9.38% and 7.78%, respectively. CONCLUSIONS: This grading system could guide frontal contusion treatment, which could help patients to achieve a good healing rate and reduce the failure rate.
