Bilaminar connective tissue graft as an alternative treatment of leukoplakia: Case report

Oral leukoplakia is a predominantly white lesion of the oral mucosa that cannot be clinicopathologically characterized as any other definable lesion. Any oral site may be affected by leukoplakia, the most common sites being buccal and alveolar mucosa, floor of the mouth, tongue, lips, and palate. To date there is no evidence of effective treatment of oral leukoplakia that may prevent recurrence. This case report describes a new surgical technique using a bilaminar connective tissue graft in the treatment of oral leukoplakia. During the regular periodontal recall visit, the clinical diagnosis of gingival leukoplakia at the maxillary left sextant was established in a 45-year-old patient. Histopathologic analysis suggested reactive hyperkeratosis. The patient agreed to a new surgical treatment of the lesion. Under local anesthesia a 20-mm-long bilaminar connective tissue graft was interposed between the affected tissue and the bone. Healing was followed by the disappearance of the white lesion within the borders of the underlying graft. Five years after therapy, the treated area remained intact, with no clinical sign of recurrence.
