Keystone Island Flap for Reconstructive Surgery-A Novel Approach

Area of Science:

• Plastic Surgery
• Dermatologic Surgery
• Reconstructive Surgery

Background:

• Keystone island flaps are increasingly utilized in reconstructive surgery.
• These flaps are based on fasciocutaneous perforators and are trapezoidal in shape.
• They are effective for closing defects after skin tumor excision.

Observation:

• A case study involving a 79-year-old male patient is presented.
• The patient underwent reconstruction using a keystone island flap.
• This was performed after the surgical excision of biopsy-proven Bowen's disease.

Findings:

• The keystone island flap procedure resulted in a favorable outcome.
• Both aesthetic and functional results were deemed good.
• This highlights the flap's efficacy in specific oncologic reconstructions.

Implications:

• The keystone island flap is a valuable technique for complex defect closure.
• Individualized defect closure is crucial for optimal cosmetic results in reconstructive surgery.
• This case supports the expanding applications of keystone island flaps in achieving good cosmesis.
