Review of Hard Palate Lipoma and Retrospective Clinicopathological Analysis of Patients With Oral Lipomas

Abstract

Lipomas occurring in the hard palate are extremely rare, and treating lipomas in this area presents challenges due to the thinness of soft tissue and the risk of postoperative bony surface exposure. We present a case of hard palate lipoma that was successfully removed using the partial thickness flap dissection technique. In addition, we reviewed the clinicopathological features of 20 reported cases of hard palate lipomas worldwide and retrospectively analyzed the clinical characteristics and pathological types of 68 oral lipomas in China. The use of a partial thickness flap demonstrates potential effectiveness in excising benign masses located in the hard palate. Regarding 68 patients with oral lipomas, the most commonly affected sites were the buccal region, tongue, and floor of the mouth. Histologically, simple lipomas and fibrolipomas were the predominant types observed.
