Mucous-flap method for cleft-lip revision using transverse everted full-length lower-lip flap

Area of Science:

• Plastic Surgery
• Craniofacial Surgery
• Reconstructive Surgery

Background:

• Cleft lip repair can result in asymmetrical lip volume, particularly with a smaller upper lip.
• Previous cleft lip surgeries may lead to insufficient tissue for optimal upper lip reconstruction.
• Addressing tissue deficit in the upper prolabium is crucial for aesthetic and functional outcomes.

Purpose of the Study:

• To evaluate the efficacy of a full-length mucous flap transfer from the lower to the upper lip.
• To improve upper lip tissue volume and external appearance in patients with prior cleft lip surgery.
• To assess the safety and feasibility of this reconstructive technique.

Main Methods:

• A cohort of 6 patients with cleft lip and smaller upper lip tissue volume underwent the described surgical procedure.
• Tissue was transferred from the lower lip to the upper lip using a full-length mucous flap.
• Patients were followed postoperatively for up to 3 years.

Main Results:

• The mucous flap transfer successfully increased upper lip tissue volume.
• Significant improvements in the external appearance of the lips were observed.
• The procedure was well-tolerated under topical anesthesia, with no restrictions on mouth opening or oral intake.

Conclusions:

• This surgical technique is effective for correcting upper lip tissue deficiency in secondary cleft lip repairs.
• The procedure offers a safe, minimally invasive option with good aesthetic and functional results.
• It is recommended for cleft lip cases with insufficient upper prolabium volume post-initial surgery.
