Our Definition of Propeller Flaps and Their Classification

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Microsurgery

Background:

• The propeller flap concept was initially defined for burn scar contracture release.
• Evolution of propeller flaps integrated with perforator flap techniques.
• Previous classifications like the Tokyo consensus established foundational definitions.

Purpose of the Study:

• To propose an updated and comprehensive classification of propeller flaps.
• To refine understanding based on vascular pedicle characteristics and recent advancements.
• To consolidate existing knowledge and new developments in propeller flap surgery.

Main Methods:

• Review and synthesis of previous classifications and subsequent publications.
• Development of a new classification system based on vascular pedicle.
• Identification of key variables for flap classification (pedicle type, rotation, origin, shape).

Main Results:

• Proposed classification includes five main types of propeller flaps: SPP, PPP (including SCP subtype), APP, muscle propeller, and chimeric propeller.
• Classification considers pedicle type, rotation degree, pedicle position, artery of origin, and flap shape.
• This updated system provides a more comprehensive framework for understanding propeller flap variations.

Conclusions:

• The proposed classification offers a detailed and updated system for propeller flaps.
• This framework aids in standardizing terminology and understanding diverse applications.
• Further research and clinical application will validate the utility of this comprehensive classification.
