perforator flap
Tissue flap that includes skin and fat while preserving underlying muscle by using only small perforating blood vessels.
Full Definition
A perforator flap is an advanced reconstructive technique that preserves muscle function by utilizing only the small perforating blood vessels that traverse through muscle to supply overlying skin and subcutaneous tissue. This approach reduces donor site morbidity compared to traditional muscle-containing flaps while maintaining reliable blood supply. Common examples include DIEP, SIEA, and GAP flaps. The technique requires detailed knowledge of vascular anatomy and advanced microsurgical skills for optimal outcomes.
Usage
Usage note: Specify the anatomical location (e.g., 'anterolateral thigh perforator flap').
