title: [Study of amount of bleeding in endoscopic sinus surgery].
abstract: The amount of bleeding and its relative factors were statistically analysed. The result showed that amount of bleeding was closely related to following factors, time of operation, type of anesthesia, pattern and duration of surgical procedure, and skill of surgeons. The non-elasticity of blood vessels in scar tissue, and abnormal vessels in hyperplastic pathologic tissue were the most important factors which induced bleeding in patients for revision surgery. In order to reduce bleeding, some devices were suggested.
