Trapezius osteomyocutaneous flap for mandibular reconstruction

Area of Science:

• Head and Neck Surgery
• Reconstructive Surgery
• Oral and Maxillofacial Surgery

Background:

• Reconstructing the anterior mandibular arch and floor of mouth is a complex surgical challenge.
• Myocutaneous flaps are increasingly being explored for these demanding reconstructions.
• Incorporating bone into flaps offers potential for improved structural integrity.

Purpose of the Study:

• To evaluate the efficacy of the trapezius osteomyocutaneous compound flap for mandibular reconstruction.
• To assess the long-term stability and outcomes of using the scapula bone with this flap.

Main Methods:

• Utilized the trapezius osteomyocutaneous compound flap, incorporating scapula bone.
• Focused on reconstructions of the anterior mandibular arch and floor of mouth.
• Monitored patients for bone resorption and functional outcomes for over two years postoperatively.

Main Results:

• The trapezius osteomyocutaneous flap successfully reconstructed the mandible from angle to angle.
• The scapula bone, with its rich periosteal blood supply, demonstrated no resorption at over two years postoperatively.
• This technique proved effective for challenging head and neck reconstructions.

Conclusions:

• The trapezius osteomyocutaneous compound flap is a viable and effective option for anterior mandibular and floor of mouth reconstruction.
• The inherent vascularity of the scapula bone contributes to its long-term stability, avoiding resorption.
• This flap offers a reliable solution for complex head and neck defects, improving patient outcomes.
