Comparison of odor detection test (ODT) results. The ODT was performed on days 0, 14, and 28. Results are presented as means ± 1 SD. No difference among the 3 groups was seen on days 0 and 14. On day 28, the results of the basic fibroblast growth factor (bFGF)–gelatin hydrogel group were significantly better than those of the other 2 groups (Kruskal-Wallis test; P <.05). Figure Legend:

Histologic findings of the olfactory epithelium on day 28 (orginal magnification ×400, hematoxylin-eosin staining). *Olfactory epithelium thickness differed among the 3 groups: basic fibroblast growth factor (bFGF)–gelatin hydrogel (A), phosphate- buffered saline (PBS) (B), and bFGF (C). Scale bar, 50 μm. Figure Legend:

Comparison of olfactory epithelium thickness on day 28. Results are presented as means ± 1 SD. Thickness of the olfactory epithelium in the basic fibroblast growth factor (bFGF)–gelatin hydrogel group was significantly greater than in the other 2 groups (Kruskal-Wallis test; P <.05).

Immunostaining of olfactory marker protein (OMP) on day 28 (orginal magnification ×400, hematoxylin-eosin staining). Many OMP-positive cells (brown) were identified in the basic fibroblast growth factor (bFGF)–gelatin hydrogel group (A), while the numbers of such cells were markedly lower in the phosphate-buffered saline (PBS) (B) and bFGF (C) groups. Scale bar indicates 50 μm. Figure Legend:
