CONSERVATIVE TREATMENT OF EXTENSIVE MANDIBULAR MIDLINE CYSTIC LESION—CASE REPORT

Abstract

This case reports a conservative treatment of a large cystic lesion in the midline of the mandible. The 54-year-old female patient underwent clinical examinations and computed tomography because of a swelling with a hard consistency located in the vestibular region of the middle line of the mandible. A fine needle aspiration cytology and incisional biopsy procedure were performed. The histopathologic analysis showed a thin epithelial lining with no projections with prominent areas of the capsule, resulting in the diagnosis of residual cyst. The treatment was defined as the decompression of the cyst, followed by enucleation with the purpose of bone neoformation, and the closure of the vestibular wall with flap rotation. The patient was followed up without relapse, presenting total bone recovery. Decompression is a good option because it allows the bone defect to heal without grafting and guided regeneration in cases of inflammatory nature.
