“…Ameloblastomas have been found located in the mandible in around 80% of the cases and in the maxilla in the remaining 20%. 3 , 8 , 11 , 12 , 14 In our study, all of them were located in the mandible, and this is close to the data found by Kim and Jang, 5 who in a study on 71 cases observed occurrences of ameloblastomas in the mandible in 93.9% of them. In the same study, the location was only in the body of the mandible in 60.6% of the cases and in the body and angle in 2.8% of the cases, while there were no cases located simultaneously in the body, angle and ramus of the mandible.…”

Ameloblastomas are odontogenic tumors that are locally invasive and slow-growing. Their etiology is still not well defined, but the forms of treatment have been widely discussed because of the possibility of tumor recurrence and postoperative complications. In this study, six patients who were diagnosed with ameloblastoma in the mandibular region and were treated in the Department of Orthopedics and Traumatology of Hospital das Clínicas, Federal University of Goiás, between 1958 and 1963, were evaluated. The radiological, clinical and therapeutic characteristics were evaluated. There was no predominance regarding gender in the sample studied. The symptoms most often presented by the patients were pain and tumor formation. The radiological characteristics with greatest incidence were multilocular lesions and the treatment used for all the patients was radical surgery. There was no recurrence over the minimum follow-up period of one year and six months.

“…Because infiltration between the trabeculae of spongeous bone can occur, the recommended treatment for solid or multicystic ameloblastoma consists of wide resection to prevent recurrences and the possible progression to malignancy. A high recurrence rate, particularly after conservative treatments, is not uncommon for this type of odontogenic tumor 23 . Given these high recurrence rates, which vary between 50 and 90% after conservative treatment, several authors have supported surgical resection with safety margins for the treatment of solid or multicystic ameloblastomas and have advocated bone resection in the affected area with at least 15 mm of healthy adjacent tissue beyond the radiographic borders of the lesion , as performed in both of the above mentioned cases.…”

“…The typical ameloblastoma begins as a slowly destructive asymptomatic and intraosseous expansion, being a lesion that tends to expand and infiltrate, rather than perforate the bone. However, the diagnosis can also be suggested through a routine radiographic examination 19 . As observed in the above mentioned cases, unless the tumor becomes infected, it is rarely painful.…”

The tumour is by far more common in the mandible than in the maxilla and shows predilection for various parts of the mandible in different racial groups 4. The relative frequency of the mandible to maxilla is reported as varying from 80-20%. It often presents as a slow growing, painless swelling, causing expansion of the cortical bone, perforation of the lingual and or buccal plates and infiltration of soft tissue. There is often delay in the diagnosis because of its slow-growing nature 5. Ameloblastoma of the jaws is the most commonly encountered odontogenic tumour in Africa 6-9 and Asia 10,11 but the second most common odontogenic tumour in North and South America 12-14. The aim of the present study was to critically review the pertinent literature and determine the most appropriate method of treatment for ameloblastomas. Case report Case 1 A 66-years-old female patient sought treatment at the Oral and maxillofacial department due to a localized swelling and asymptomatic intraoral lesion on the posterior region of the left inferior alveolar ridge. The lesion exhibited no

Ameloblastoma is an uncommon odontogenic neoplasm that accounts for approximately 10% of all tumors originating from gnathic bones. Although its growth is localized, the tumor can also be infiltrative and persistent; however, its behavior is usually benign. The mandible is the most commonly affected site, and ameloblastoma is most frequently diagnosed between the fourth and fifth decades of life. In addition to a brief review of the literature, the present study discusses the clinical, imaging, histopathological and prognostic characteristics of these tumors by presenting two case reports. In these cases, the patients were aged 40 and 66 years, of different sexes and ethnicities and presented with the same complaint regarding localized and asymptomatic swelling. Both cases occurred in the posterior region (but on opposite sides) of the mandible. The patients were initially subjected to clinical examination and imaging of the face, followed by incisional biopsy to confirm (in both cases) the diagnosis of multicystic intraosseous ameloblastoma with a plexiform pattern. Both patients were treated by wide resection of the lesion (with safety margins), and only one patient experienced tumor recurrence. After 42 and 68 months of follow-up, the patients are still alive and show no signs of recurrence. Clinical and imaging findings aid in the differential diagnosis of ameloblastomas; however, histopathological evaluation is essential for its definitive diagnosis. Early diagnosis and precise detection of the borders to provide adequate safety margins during the surgical resection of the tumor are necessary to achieve successful treatment and recurrence-free survival for solid ameloblastomas.
