The average hospitalization time for patients in EVH group was 5.5 ± 2.4 days and that for OVH group was 9.5 ± 2.7 days. In OVH group, hematomas were detected in 5 patients and were surgically evacuated, but in EVH group included one patient with tunnel hematoma which managed conservatively and resolved spontaneously. We used suction drains (Radivac) in 25 cases of EVH without significant difference in result. In EVH group, edema occurred less frequently. Infection of the incision location did not occur in EVH group. There was significantly more wound serous discharge in above ankle incision site of OVH group when compared to the above knee incision site in EVH group. In OVH group, two patients with dehiscence were treated as OPD clinic with daily dressings and oral antibiotics. Nine patients with delayed wound healing treated without antibiotics.
