RÉSUMÉ
Ameloblastomas are rare, locally invasive and slowly growing and tumours with high recurrence rate. If they are not treated on time, they can reach an emormous size. Benign mandibular swellings are broadly divided into odontogenic and non-odontogenic tumours. Ameloblastoma is one of the most common benign tumours of odontogenic origin which developed from epithelial cells and its elements and dental tissues in their various phases of development. Patients with Giant Ameloblastomas are very rare but they are widely found and diagnosed in developing countries because of painless growth and patient’s fear of Surgery leading to delayed treatment. This paper presents a case of large Ameloblastoma of left side of mandible in a 25-year-old female patient which was successfully resected in toto. Patient refused for free fibula flap re-construction of the defect because of her apprehension for donor site morbidity
