Double-paddle peroneal flap for extensive lip defect reconstruction.

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Oral and Maxillofacial Surgery

Background:

• Reconstructive surgeons have various options for lip defect repair.
• This study details the use of free double-paddle peroneal flaps for extensive lip reconstruction.

Purpose of the Study:

• To evaluate the efficacy of free double-paddle peroneal flaps in reconstructing extensive lip defects.
• To assess functional and cosmetic outcomes following this reconstructive technique.

Main Methods:

• 16 patients with extensive lip defects post-tumor ablation underwent reconstruction using free double-paddle peroneal flaps.
• Flap design involved superiorly placed intraoral and inferiorly placed extraoral skin paddles.
• Techniques for vermilion border creation and lip fullness were employed.

Main Results:

• Flap sizes ranged from 10-15 cm × 3-13 cm (intraoral) and 4-10.5 cm × 2.5-10.5 cm (extraoral).
• One case of venous thrombosis was successfully salvaged; superficial necrosis occurred in one flap.
• All patients achieved mouth closure without drooling during the 0.5-33 month follow-up.

Conclusions:

• Free double-paddle peroneal flap transfer enhances lip definition, vestibule depth, and oral commissure angle.
• The technique results in satisfactory oral competency and improved cosmetic appearance.
• This method is a viable option for extensive lip defect reconstruction.
