Partial reconstruction of the auricle with the tubed postauricular flap: a case report

The authors present a case of a partial auricular deformity acquired from a human bite that was reconstructed using a 3-stage posterior auricular tubed flap. Helical rim avulsions may be ideally reconstructed with a tubed flap created from lax postauricular soft tissue. During the third stage, division and inset of the inferior pedicle of the flap were complicated by venous congestion. The use of leech therapy and topical nitroglycerin successfully improved flap circulation. Given the occurrence of venous congestion due to a sudden change in flap blood circulation, the authors propose a pedicle compression device to be used in the future that assists with flap conditioning. This physiological delay helps minimize flap ischemia by allowing choke vessels to dilate within, thus increasing flap reliability. Therefore, when the pedicle is divided, improved circulation from the previously inset superior pedicle has been established with a decreased risk of venous congestion and arterial insufficiency.
