The anatomic basis for the platysma skin flap

Area of Science:

• Anatomy
• Vascular Surgery

Background:

• Understanding neck vasculature is crucial for reconstructive surgery.
• The platysma muscle and overlying skin require specific blood supply considerations.

Observation:

• Direct cutaneous arteries, typically 0.5 mm in diameter, supply the platysma and skin.
• These arteries originate from various neck vessels including occipital, facial, and subclavian arteries.
• Myocutaneous blood supply through the sternocleidomastoid muscle is limited.

Findings:

• The platysma flap's survival depends on maintaining blood supply from at least one source region.
• Incorporating the external jugular or communicating veins may enhance flap viability.
• Successful facial reconstruction was achieved in 7 of 8 patients using these principles.

Implications:

• This detailed vascular mapping informs surgical planning for platysma flaps.
• Optimized flap design can improve outcomes in facial reconstruction.
• The study highlights the importance of direct cutaneous vascularization for flap survival.
