Background: Mucoepidermoid carcinoma (MEC) is the most common malignant epithelial tumor of the salivary gland in the oral cavity. In South Korea, it occurs most frequently in the palate, retromolar area, floor of the mouth, buccal mucosa, and other areas of the oral cavity. MEC is rare in children and adolescents under 20 years of age, but it is the most common malignant salivary gland tumor in this group. Reconstructive surgery is often required due to cystic lesions or resection of malignancy in the oral cavity. Buccal fat pad (BFP) is a flap that is reliable and suitable for reconstructing oral defects because it has a low complication rate and small volume change over time. Case Presentation: We report the case of a 12-year-old female patient with low-grade MEC on light soft palate with no neck metastasis. After tumor resection the palatal mucosal defect was reconstructed with a BFP flap. Conclusion: The purpose of this article is to discuss the features and treatment methods of MEC that is rarely occurring in children, and the usefulness of BFP for reconstruction. Therefore, we will make a precise diagnosis and treatment as we examine the clinical feature and review the literature.
