Enhancing Precision and Esthetics: Endoscopy-Assisted Total Maxillectomy for Locally Invasive Maxillary Ameloblastoma Using Contralateral Transmaxillary Approach Without Subciliary Incision.

This report presents a notable approach to treating a locally invasive maxillary ameloblastoma in a 46-year-old woman using an endoscopy-assisted total maxillectomy via a contralateral transmaxillary approach without a subciliary incision. Ameloblastomas, though benign, require radical surgical management due to their aggressive nature and high recurrence rates, especially in the maxilla. Traditional techniques often involve extensive facial incisions, leading to significant scarring and potential complications. In this case, the notable approach allowed for precise osteotomy of the pterygoid process and accurate delineation of the mucosal margins during ethmoidectomy while preserving facial esthetics. The surgery achieved complete tumor resection with successful reconstruction, avoiding the esthetic drawbacks associated with conventional methods. Postoperative recovery was uneventful, with no residual tumor observed at the six-month follow-up. This technique demonstrates the potential for reducing surgical morbidity and improving cosmetic outcomes in the management of complex maxillary tumors.
