Summary
The sterno-omohyoid flap offers a novel solution for dynamic facial reanimation in cases of chronic facial paralysis. This technique shows promise for achieving a synchronous smile with improved facial symmetry.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Microsurgery
Background:
- Chronic facial palsy often necessitates reconstructive surgery to restore dynamic smile function.
- Existing methods for facial reanimation have limitations in achieving natural, synchronous smile.
- Ideal reconstruction requires a suitable muscle flap with a reliable vascular and neural supply.
Observation:
- A novel sterno-omohyoid, dual-vector flap was evaluated for facial reanimation.
- The procedure involved free tissue transfer of the sterno-omohyoid muscles with the superior thyroid artery, middle thyroid vein, and ansa cervicalis.
- This technique was applied to a patient with longstanding facial palsy due to skull base tumor resection.
Findings:
- The patient achieved a dynamic smile within six months post-operation.
- Objective facial symmetry showed significant improvement.
- This represents the first reported use of the sterno-omohyoid flap for facial reanimation.
Implications:
- The sterno-omohyoid flap presents a promising alternative for facial reanimation.
- It offers potential advantages over traditional flaps, including minimal facial bulk and improved smile synchrony.
- Further studies are warranted to fully establish the potential of this novel flap in facial reanimation.

The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
