Surgical approach to oral lichen planus by submucosal autologous fat grafting.

Oral lichen planus is a chronic autoinflammatory mucositis. Oral lesions are predominantly white; they tend to be bilateral while involving the buccal mucosa especially cheek, tongue, gums, lips, and palate. Many topical and systemic agents are currently used with unpredictable results. Fat grafting is characterized by the placement of multiple parcels of purified fat with blunt cannulas; at the beginning, it was introduced to improve facial aesthetics. Recently, it has been translated to other surgical cases such as posttraumatic deformities and craniofacial anomalies and as ancillary reconstructive procedure after tumor resections. The successful results of this procedure encouraged us to use this approach to a clinical case of oral lichen planus refractory to conventional therapy.
