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.)
