We compared the surgical efficacy of the supraorbital key-hole approach (SKA) to conventional unilateral frontotemporal craniotomy (UFTC) for the treatment of patients with unilateral-dominant bilateral frontal contusions (BFCs). A retrospective analysis of 62 patients with unilateral-dominant BFCs who underwent surgery at our institute between 2014 and 2017 was performed. There were 26 patients who underwent SKA (group A) and 36 who underwent UFTC (group B). Postoperative computed tomography scans showed satisfactory evacuation of the frontal cerebral contusions in both groups (p > 0.05). There was less intraoperative blood loss in group A than group B (17.1 ± 4.55 vs. 67.6 ± 10.28 mL, p < 0.05). The operative time was also shorter in group A (82.7 ± 13.73 vs. 132.4 ± 9.17 min, p < 0.05). Postoperative bleeding occurred in three cases in group A and in only one case in group B (p > 0.05). The average length of hospitalization was shorter in group A than group B (7.3 ± 1.09 vs. 12.9 ± 1.71 days, p < 0.05). No differences in the Glasgow Outcome Scale were observed between the two groups after 6 months of follow-up (p > 0.05). Thus, compared to UFTC, SKA is associated with shorter operation times and less trauma to the surrounding brain tissue.
