Treatment of a Large Mandibular Ameloblastoma by Marsupialisation and Marginal Resection Preserves the Mandibular Inferior Border

Ameloblastomas are benign locally invasive odontogenic tumours. Involvement of the inferior border of the mandible in ameloblastomas usually requires segmental mandibulectomy. This report is of a 72-year-old man with a large mandibular ameloblastoma composed of a large cystic part and a solid multicystic part. A 2-stage operation, consisting of marsupialisation and subsequent marginal resection, enabled the preservation of the inferior mandibular border. There was no evidence of recurrence 55 months after the resection.
