The effect of platelet-rich plasma on survival of the composite graft and the proper time of injection in a rabbit ear composite graft model.

Background: Administration of growth factors has been associated with increased viability of composite grafts greater than 1-cm in diameter. Platelet-rich plasma (PRP) contains many of the growth factors studied. In this study, we evaluate the effect of PRP injection on composite graft viability and the proper time for injection.

Regional analysis of soft tissue thickness on korean buttocks and application to fasciocutaneous flap design.

Background: Various shapes and designs of the gluteal artery perforator flap have been used for treating sacral pressure sores and reconstructing breasts. To establish the ideal fasciocutaneous flap design for use in the gluteal area, the soft tissue thickness distribution was measured.

Methods: Twenty-one buttocks of adult Korean cadavers were analyzed through rectangular subfascial dissection.

A new method for creating a definite philtrum by the flipping of an orbicularis oris muscle flap in a patient with an indistinct philtrum.

The philtrum plays a key role in the appearance of the upper lip and nostril sill. Therefore, construction of the philtrum is crucial for attaining a natural appearance of the upper lip. We used a flipping myoplasty of the orbicularis oris muscle on a patient with a flat philtrum in order to effectively reconstruct the philtral dimple and column.
