Figure 12 One-month postoperative case shows: (a, b) Merocel packed side with hyperplastic respiratory epithelium with numerous goblet cells resting on thickened basal lamina (↑). The lamina propria shows newly formed blood vessels (bv) and hyperproliferated glands with increased activity (g). (c) Stammberger’s Sinu-Foam packed side shows defective epithelial restoration resting on thin basal lamina (↑). The lamina propria shows subepithelial marked angiogenesis activity (bv). Increased fibroblastic (▲) activity and cellular infiltration are also noticed. Hematoxylin and eosin stain Mic. magnification, a, b, and c, ×100; insets in a, b, and c, ×400.
