Some cases have been published by Harris and Weiss1 and by Rock.2 Kaufmann and Schuknecht3 have recently (1967) described ten more cases.

Absorbable gelatin sponge (Gelfoam) wire implants resulted in such reparative granulomas as often as fat-wire implants. The main symptom was curiously enough a bone conduction hearing loss with little or no air conductive component. After reoperation and cleansing of the oval window the hearing was reestablished.
