Figure 1. Comparison of the flap necrotic area between the two groups.

Figure 1

A. Necrosis status of flaps between two groups at 3rd and 7th postoperative day. On the 3rd day, flap necrotic area didn’t show apparent difference between the two group. On the 7th day, flap necrotic area of the COX-2 inhibitor group was larger than control group. B. On the 7th day, the flap necrotic area ratio in the the selective COX-2 inhibitor group (66.65±2.81)% was significantly enlarged than control group(48.81±2.33)% (**P<0.01).
