Preexpanded radial forearm free flap to the scalp

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Microsurgery

Background:

• The radial forearm flap is a well-established reconstructive option due to its favorable characteristics.
• Its primary limitation is the relatively small size, restricting application in extensive defects.
• Head and neck reconstruction frequently utilizes this flap for its aesthetic and functional match.

Observation:

• A technique for pre-expansion of the radial forearm flap was employed.
• This method was specifically applied to address a large scalp defect.
• An incidental finding was the formation of a periprosthetic capsule.

Findings:

• Pre-expansion markedly increases the available surface area of the radial forearm flap.
• The flap's size can be augmented without compromising its neurovascular pedicle.
• The periprosthetic capsule provided an ideal substrate for subsequent skin grafting.

Implications:

• Pre-expansion offers a viable solution for utilizing the radial forearm flap in larger reconstructive challenges.
• This technique enhances the versatility of the radial forearm flap in head and neck surgery.
• The periprosthetic capsule presents a novel opportunity for improved outcomes in forearm defect reconstruction.
