[Histopathologic findings in the posterior pharyngeal wall 8 years after treatment of velar insufficiency with Teflon injection].

Abstract

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.
