An Innovative Approach of Utilizing the Digastric Tendon for Lower Lip Soft Tissue Repair: A Case Report.

Lower lip reconstruction following oral and neck oncosurgery presents significant challenges in maintaining function and esthetics. This case report describes a novel application of the digastric tendon for repairing the soft tissue of the lower lip in a patient undergoing wide excision of a lesion, bilateral modified radical neck dissection, segmental mandibulectomy, and free fibula flap repair. This innovative approach aims to maintain oral competence, strengthen the flap, and enhance esthetics. The digastric tendon was chosen due to its accessibility and effectiveness in strengthening the lower lip.
