Lip reconstruction with motor and sensory innervated composite flaps

Area of Science:

• Plastic Surgery
• Reconstructive Surgery

Background:

• Oral sphincter and lip defects require complex reconstruction.
• Previous methods often compromised function and sensation.

Observation:

• Innervated composite skin-muscle-mucosal flaps utilize perioral muscles (orbicularis oris, depressor anguli oris, levator anguli oris).
• These flaps preserve motor and sensory innervation while restoring lip form and function.
• Flap design is tailored to specific lip defects, including central, lateral, and total lip reconstructions.

Findings:

• Innervated composite flaps effectively restore oral sphincter function and lip aesthetics.
• Specific flaps (orbicularis oris, depressor anguli oris, levator anguli oris) are indicated for distinct lip defect types.
• These flaps provide superior functional and sensory outcomes compared to traditional techniques.

Implications:

• Innervated composite flaps represent a significant advancement in oral sphincter and lip reconstruction.
• Preserved nerve function enhances patient quality of life after complex defect repair.
• These techniques offer improved functional restoration for patients with significant lip loss.
