Summary of "Different techniques for caudal extension graft placement in rhinoplasty: ptDiferentes técnicas para colocação de enxerto de extensão caudal em rinoplastia."

The caudal extension graft is usually a cartilage graft that overlaps the caudal margin of the nasal septum. A combination of the caudal extension graft and the tongue-in-groove technique is used to stabilize the nasal base, set tip projection, and refine the alar-columellar relationship.

Control of Nasal Tip Position: Quantitative Assessment of Columellar Strut vs Caudal Septal Extension Graft.

Control and maintenance of nasal tip position is critical in rhinoplasty. Two frequent methods to exert tip control are: columellar strut (CS) and caudal septal extension graft (SEG). However, no quan...

Medical and Biotech [MESH] Definitions

The immune responses of a host to a graft. A specific response is GRAFT REJECTION.

An immunological attack mounted by a graft against the host because of tissue incompatibility when immunologically competent cells are transplanted to an immunologically incompetent host; the resulting clinical picture is that of GRAFT VS HOST DISEASE.

The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host.

The induction of prolonged survival and growth of allografts of either tumors or normal tissues which would ordinarily be rejected. It may be induced passively by introducing graft-specific antibodies from previously immunized donors, which bind to the graft's surface antigens, masking them from recognition by T-cells; or actively by prior immunization of the recipient with graft antigens which evoke specific antibodies and form antigen-antibody complexes which bind to the antigen receptor sites of the T-cells and block their cytotoxic activity.

The stable placement of surgically induced fractures of the mandible or maxilla through the use of elastics, wire ligatures, arch bars, or other splints. It is used often in the cosmetic surgery of retrognathism and prognathism. (From Dorland, 28th ed, p636)
