Composite tragal perichondrial/cartilage autografts vs cartilage or bone paste grafts in tympanoplasty.

Extrusion of plastic or ceramic implants is a significant cause of failure in ossiculoplasty for chronic ear disease. This paper reports the use of a composite tragal cartilage and perichondrial autograft compared to cartilage or bone paste between the graft and tympanic membrane. At 2 years, there were no extrusions in the group with the composite graft (n = 18) and 5 extrusions in the cartilage/bone paste group (n = 18) (P = 0.02). The mean average air-bone gap was significantly better for the composite grafts at 2 years (15 dB vs 24 dB) (P less than 0.05). Extrusions were eliminated and hearing results better at 2 years using the composite graft.
