[Rotation myoplasty using the sternocleidomastoid muscle, together with hemimandibulectomy]

Area of Science:

• Head and Neck Surgery
• Reconstructive Surgery
• Oral Oncology

Context:

• Hemi-mandibulectomy involves the surgical removal of half of the mandible.
• Reconstruction is crucial for restoring function and aesthetics after extensive cancer surgery.
• Prosthetic rehabilitation requires adequate structural support within the oral cavity.

Purpose:

• To evaluate the functional and aesthetic outcomes of sternomastoid muscle rotation myoplasty following hemi-mandibulectomy.
• To assess the muscle's ability to contain a prosthesis and restore facial contour.
• To determine the procedure's efficacy in improving the symmetry of the lower face.

Summary:

• Rotation myoplasty utilizing the sternomastoid muscle provides functional advantages by reinforcing the buccal cavity wall.
• Post-fibrous transformation, the muscle offers a stable contour essential for effective prosthesis retention.
• The procedure significantly contributes to plastic restoration, enhancing the aesthetic symmetry of the lower facial region.

Impact:

• This reconstructive technique improves patient quality of life by restoring both oral function and facial appearance.
• It offers a valuable solution for patients undergoing hemi-mandibulectomy, particularly those requiring prosthetic rehabilitation.
• The dual functional and aesthetic benefits highlight the procedure's importance in comprehensive head and neck cancer treatment.
