Comparison of the microvascular density (Dbox) in the six annular zones of the RVN and the SVP of all 32 patients. A: C1, C4, and C6 were found to be statistically significantly lower postoperatively in the RVN (C1: p=0.037*, C4: p=0.026*, C6: p=0.024*) and recovered to preoperative level 3 months postoperatively. B: C4 and C6 significantly decreased after 1 month (C4: p=0.031*, C6: p=0.021*) and recovered to preoperative level 3 months postoperatively. The data was expressed as mean±SD . * denotes p<0.05, ** denotes p<0.01.
