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.

Key words: Ameloblastoma, Case management, Drainage, Palatal obturators, Surgical procedures, operative
