FIG. 6.

Histologic sections of implanted arytenoid at 1 month post-implantation. The native (N)/implant (I) interface is shown (A, B). The implanted samples were well integrated with the native tissue, and some areas of new cartilage formation were observed. Evidence of epithelialization (arrow, C) was within the newly formed tissues. Gross morphologic view of intact (left) and bisected larynx (right) at euthanasia is shown (D). (A, C) Hematoxylin and eosin, and (B) safranin O (red=glycosaminoglycan). No positive staining was observed for Verhoeff's elastic stain (not shown). Magnification=4× objective, scale bar=300 μm. Inset magnification=20× objective, scale bar=100 μm. Color images available online at www.liebertpub.com/tea
