Figure 2. Changes in the postoperative graft epithelization and graft edema score.
(A) The percentage of epithelization was measured by two otologic specialists based on the ratio of the epithelized neodrum in the entire grafted eardrum.Significantly higher epithelialization percentages wereobserved in NGPG compared to GPG at1-and 2-months visits (p <0.05). (B) The severity of edema of the grafted fascia was quantified by two otologic specialists; none=0, mild=1, moderate=2, and severe=3.The edema score of the graft in NGPG was lower in NGPG than in GPG at postoperative 1- and 2-months visits, thereby indicatinga better healing process in the NGPG(p <0.05). (GPG; gelfoam-packing group, NGPG; non-gelfoam-packing group. Error bars indicate standard deviations.*P < 0.05. Student’s t-test.)
