摘要:

Summary:Successful canal wall reconstruction after open cavity surgery may be compromised by both immediate (graft dehiscence and infection) or delayed (graft retraction, absorption, and extrusion) complications. Many of the healing problems following canal wall reconstruction are related to incomplete soft tissue coverage of the graft and limited blood supply. Under these conditions, we sought to increase graft viability with a broad-based perichondrial flap developed from the posterior surface of the auricle. The flap was used over a period of 3 years at a tertiary referral center in 36 cases of canal wall reconstruction in conjunction with composite grafts of cartilage and perichondrium. The patients ranged in age from 12 to 63 years and in all cases had undergone a canal down tympanomastoidectomy that was reconstructed either primarily or secondarily. The canal wall was successfully reconstructed in 35 of 36 ears. These results demonstrate a reduction in our dehiscence rate from 10 to 3% since the introduction of the perichondrial flap. With the perichondrial flap, we were consistently able to achieve better soft tissue coverage of the composite cartilage graft, eliminate lateral graft dehiscence, and encourage reepithelization of the canal. By implication, we believe this flap provides a source of nutritional support for the free cartilage graft as well as the overlying skin.
