Abbe flap
Pronunciation: AB-ee
A cross-lip pedicled flap used for lip reconstruction that transfers tissue from one lip to reconstruct defects in the opposite lip.
Full Definition
The Abbe flap is a classic reconstructive technique used in lip surgery that involves transferring a full-thickness segment of tissue from one lip to reconstruct defects in the opposite lip while maintaining its vascular pedicle. Named after Dr. Robert Abbe, this bipedicled flap is particularly useful for central lower lip reconstruction using upper lip tissue, or vice versa. The procedure requires a two-stage approach: initial flap transfer with pedicle preservation, followed by pedicle division approximately 2-3 weeks later once the flap has established new blood supply. This technique is valuable for maintaining lip competence, sensation, and natural tissue characteristics in reconstruction.
Usage
Usage note: Capitalize 'Abbe' as it refers to the surgeon's name; two-stage procedure requiring pedicle division.
