After a teflon injection into the submucosa of the posterior pharyngeal wall in a child, a corrective operative procedure was carried out eight years later because of severe open nasality due to velopharyngeal incompetence. A biopsy was taken from the eight year old teflon depot. The histological examination revealed a marked foreign body reaction with a persistent inflammation and fibrosis. The micromorphological comparison of the sizes of the teflon particles in the used teflon-glycerol paste with those detected in the examined tissue sample indicates the (cellular, lymphogenic) removal of the smaller teflon particles.
在一名儿童的咽后壁黏膜下注射聚四氟乙烯后，八年后因腭咽闭合不全导致严重开放性鼻音而进行了矫正手术。从八年前的聚四氟乙烯注射部位取了活检组织。组织学检查显示有明显的异物反应，伴有持续的炎症和纤维化。将所用聚四氟乙烯 - 甘油糊剂中的聚四氟乙烯颗粒大小与在检查的组织样本中检测到的颗粒大小进行微观形态学比较，表明较小的聚四氟乙烯颗粒被（细胞性、淋巴源性）清除。
