Salivary gland tumors can also occur rarely in the retromolar area, though common near the junction of hard and soft palate, labial mucosa, and buccal mucosa. Most salivary gland tumors in the retromolar pad area are malignant and should be excised. The cystadenoma is a rare, benign, salivary gland tumor. Importantly, incomplete resection of this tumor can lead to recurrence or cervical lymph node metastasis. We reported herein a case of cystadenoma arising in the right retromolar pad area in a 63-year-old male patient who underwent reconstruction using a buccal fat pad flap (BFPF) after the surgical removal of the tumor with a 10-mm margin left a defect with bone exposure. No evidence of recurrence or complication was found at the postoperative, three-year follow-up.
涎腺肿瘤也很少发生于磨牙后区，不过在硬腭与软腭交界处、唇黏膜及颊黏膜附近较为常见。磨牙后垫区的大多数涎腺肿瘤为恶性，应予以切除。囊腺瘤是一种罕见的良性涎腺肿瘤。重要的是，该肿瘤切除不完全可导致复发或颈部淋巴结转移。我们在此报告一例63岁男性患者，其右侧磨牙后垫区发生囊腺瘤，在肿瘤切除后，距肿瘤边缘10毫米切除组织留下骨暴露缺损，遂使用颊脂垫瓣（BFPF）进行重建。术后三年随访未发现复发或并发症迹象。
