Treatment of Squamous Cell Carcinoma from the Posterior Maxilla with Wide Local Excision of the Tumor and Total Alveolectomy, Reconstruction with a Buccal Fat Pad Advancement, Placement of a Surgical Obturator, and an Ipsilateral Supraomohyoid Neck Dissection

Surgery has been the first line of treatment for oral cavity cancer. After appropriate workup, the decision to include an ipsilateral or bilateral neck dissection is made. The patient presented here was diagnosed with a posterior maxillary alveolar tumor. The treatment plan included wide local excision of the tumor with total alveolectomy, reconstruction with a buccal fat pad advancement, and placement of surgical obturator. Additionally, an ipsilateral supraomohyoid neck dissection was performed due to the relative risk of regional metastases.
Submandibular Approach to the Mandible (Cadaver)

The submandibular approach, also known as the Risdon approach, is a well-established extraoral surgical technique employed for the treatment of complex mandibular fractures and pathologies. Despite the increasing popularity of intraoral approaches for open reduction and internal fixation, the submandibular approach remains a valuable option in the arsenal of maxillofacial surgeons. This approach offers several advantages, including superior access and visualization of the mandibular body and angle, facilitating better manipulation and reduction of fracture fragments. Furthermore, the submandibular approach enables direct access to the submandibular gland, facilitating its management in cases of pathology or injury. By providing a comprehensive understanding of this technique through cadaveric exploration, this video aims to contribute to the training and education of maxillofacial surgeons, ultimately enhancing patient care and outcomes.

This is a case discussing a 21-year-old male who suffered from both non-comminuted mandibular parasymphyseal and body fractures as a result of a motor vehicle accident, requiring open reduction internal fixation (ORIF) without postoperative maxillomandibular fixation (MMF). The fracture was complicated by a broken tooth root, which required extraction.
After intraoperative MMF, ORIF was performed. The parasymphyseal fracture was plated using two locking four-hole 2-mm thick miniplates utilizing two locking screws on either side of the fracture with one plate along the alveolar surface (monocortical screw) and one along the basal surface (bicortical screw). For the right body fracture, a three-dimensional locking ladder plate was used via a transbuccal trocar approach for additional exposure needed for proper screw placement. Once the hardware was secured, the patient was taken out of MMF and restoration of premorbid occlusion was confirmed. Lastly, watertight mucosal closure was performed using absorbable sutures and Dermabond (cyanoacrylate adhesive).
