Hemostasis was performed with fibrinogen plus collagen sponge in experimental group. Hemostasis was performed gelatin sponge in control group.
Conclution Mastoid cortex bone and self-incus are feasible materiat to tympanoplasty, while self - thrombus and gelatin sponge is good support material for reconstructing auditory ossicle chains.
OBJECTIVE: To observe the effect of Iodoform-metronidazole gelatin sponge preventing dry socket.
