The surgical treatment of central giant cell granuloma of the mandible.

ABSTRACT

PURPOSE: The objective of this study was to report and evaluate our experience in the surgical treatment of mandibular central giant cell granuloma by resection without continuity defect and peripheral ostectomy. METHODS: A retrospective analysis was conducted of patients with central giant cell granuloma of the mandible who were treated between 1991 and 2000, in the Oral and Maxillofacial Surgery Unit at Jordan University of Science and Technology. A uniform surgical technique was used in all cases. The compact bone composed of the lower border of the mandible and/or posterior border of the ascending ramus, together with the nutrient periosteum attached to it, was preserved. All soft tissues in contact with or overlying the lesion and a margin of cancellous bone related to the lesion were excised. All patients were reviewed annually for a follow-up period of 1 to 9 years (mean, 3.9 years). RESULTS: Eighteen patients with central giant cell granuloma were included, (9 males and 9 females). Their age ranged from 10 to 46 years, with 89% younger than 40 years. Five (28%) lesions were in the incisor-canine region, 2 (11%) were confined to the premolar region, 4 (22%) were in the premolar-molar region, and 7 (39%) were in the molar-ramus region. All patients had aggressive central giant cell granulomas with pain, tooth mobility, and rapidly enlarging swelling. The initial diameter of lesions ranged from 2.7 to 10 cm. During the follow-up period, there was 1 case of recurrence, 2 (11%) patients had permanent lower lip paraesthesia, and no patient had obvious facial deformity. CONCLUSION: Our results suggest that resection without a continuity defect and peripheral ostectomy is a satisfactory method in the treatment of central giant cell granuloma of the mandible, with no or a very low recurrence rate and favorable postoperative function.
