Background <p>Segmental mandibulectomy is a standard surgical procedure for managing mandibular lesions, particularly oral squamous cell carcinoma. Conventional techniques may encounter difficulty during specimen retrieval due to firm attachment of the temporalis muscle to the coronoid process, resulting in increased bleeding and prolonged operative time.</p> Methods <p>A modified lateral swing technique is described in which anterior osteotomy is performed first, followed by lateral mobilization of the mandible and intraoral release of the temporalis muscle prior to posterior osteotomy. The technique is based on the author’s experience of more than 350 cases of gingivobuccal carcinoma managed between 2005 and 2025. Retrospective review of operative records and surgical logs was performed to assess operative workflow and bleeding control.</p> Results <p>Early release of the temporalis muscle improved exposure of the coronoid process and reduced resistance during specimen retrieval. The modified sequence was associated with improved intraoperative visibility, fewer bleeding episodes requiring active hemostatic intervention, and smoother specimen removal. In the author’s current practice, primary tumor resection is typically completed within 90 minutes. </p> Conclusion <p>The lateral swing-first approach with early temporalis muscle release offers a safe, reproducible alternative to the conventional sequence in segmental mandibulectomy. This modification facilitates improved access, bleeding control, and operative efficiency, and may be particularly useful in training environments and resource-limited settings.</p>
