Endoscopic Surgery of Juvenile Angiofibromawood extractives). The former, components of cell walls and intercellular layers, amount to 90–95% of oven-dry wood. Extractives occur mainly, albeit not exclusively, in the cell lumen and special tissues such as resin cells, and are extracted with water or organic solvents. The amount of minor comp

Excision by Midfacial Degloving Approach. Each period corresponds to a growing ring (an annual ring in temperate and warm-temperate zones). The light and dark colors are ascribed to the different cells formed in the earlier and the later parts of the growing season. Wood formed in the first half of growing season is composed of cells with
