The Effects of an Adhesive in the Middle Ear

Abstract

• This study investigated the effects of enbucrilate (Histoacryl) on the middle ear. Small amounts of the adhesive were used in 81 middle-ear operations performed on 50 rabbits. Light microscopic investigation of these ears 1, 2, and 3 months after surgery showed bone necrosis and a granulation tissue reaction surrounded by foreign-body giant cells. Inner-ear changes were observed in a third of the cases. Therefore, enbucrilate should only be used with extreme care and in minute quantities and never near the labyrinthine capsule.
