Ameloblastomas of the jaws: clinico-pathological review of 11 patients
European Journal of Surgical Oncology (EJSO), 2004
Aims. The ameloblastoma is an uncommon benign odontogenic neoplasm of the maxillofacial region constituting less than 1% of tumours of the oral cavity. The purpose of this paper is to discuss and evaluate the surgical treatment and the outcome from a series of 11 patients with ameloblastomas. Methods. Between the years 1995 and 2003, 11 patients (eight female and three male) aged 17-86 years (mean 52.7) suffering from ameloblastomas of the jaws were seen in our Department. Results. Ten patients were treated surgically. In eight of those radical surgery was applied. Patients with maxillary tumours were subjected to hemimaxillectomy and local excision. Radical treatment with segmental resection of the mandible was performed in six patients with multilocular (solid) mandibular ameloblastomas, with immediate reconstruction of the defect. Follow-up ranged from 3 months to 7.5 years. Conclusion. Multilocular (solid) type of tumours should be approached with radical surgical treatment. Enucleation and rarely marsupialization can be applied selectively to unilocular ameloblastomas.
Ameloblastoma–A rigorous odontogenic tumours of the jaws
International journal of health sciences
Background: Ameloblastoma is an aggressive odontogenic tumor that is often asymptomatic and slow-growing. Although it is benign in nature, due to its invasive characters and tendency to recur it is considered as a localized malignant tumour. Procedure: This is a retrospective study that involves 87 confirmed cases of ameloblastoma over 10 years. The case records and biopsy reports were retrieved from the archives of the Department of Oral & Maxillofacial Pathology and Oral Microbiology, A B Shetty Memorial Institute of Dental Sciences. Results and conclusion: The results revealed that age group between 26-50 years (49.4%) were affected the most, and had a male predilection (58.6%) and maximum involvement of jaw was mandible (88.5%), site involvement was the body of the mandible (52.9%), the radiographic feature was the multicystic type (56.3%), the histopathological variant was follicular (33.3%) and out of the total number of cases analysed 9 cases had recurrence (10.3%). Clinical ...

Approach and conservative surgical treatment of jaw ameloblastoma: case report
CES Odontología
Ameloblastoma is a benign neoplasm, originated from the odontogenic epithelium. It preferentially affects the mandible and due to its infiltrative growth pattern, it has a tendency to local recurrence. Treatment varies based on clinical, histological and radiographic characteristics. The aggressive treatment, such as marginal resection, has shown good results, however, it also has greater morbidity. Conservative treatments, such as decompression, enucleation and curettage, can also be used, with specific indications, and when carefully performed, it has a good prognosis. Thus, the objective of this work is to describe a case of mandibular ameloblastoma, treated in a more conservative way. Male patient, 53 years old, presented an increase in volume in the anterior region of the mandible. The clinical and radiographic characteristics suggested that it was a cystic lesion, so decompression and incisional biopsy were performed, the diagnosis of which was cystic ameloblastoma. The decomp...
Segmental Resection of Mandible for Treatment Unicystic Ameloblastoma: a Case Report
Malahayati Nursing Journal
ABSTRACT Ameloblastoma is the most common odontogenic tumour as it usually does not form metastasis, it is considered as benign tumour with a locally invasive growth pattern and destruction of the jaw and the surrounding tissue. Ameloblastoma annual incidence is 0.5 per 1.000.000 people, higher incidences are found in Africa, China and India in comparison with the western countries. About 80% of ameloblastomas are located in mandible, mainly in the third molar region, and 20% in the maxilla, particularly in the posterior region. Unicystic ameloblastoma is associated with a smaller relapse risk and is the only type that is susceptible for conservative surgery. Standar treatment for ameloblastoma today is radical resection with 1 cm resection margins. Recurrence range from 0 to 15% conservative surgery including enucleation and curettage recurrence rets as high as 55%. Recurrence ameloblastoma problem are associated with development of metastasis and transformation into ameloblastic ...
Maxillary ameloblastoma: results of the treatment in 11 patients
Journal of Oral Medicine and Oral Surgery
Introduction: Surgery of maxilla ameloblastoma is mutilating and the tumor propensity for recurrence high. Patients and Methods: The oral and visual functions, facial morphology and tumor recurrence in 11 patients after maxillary ameloblastoma surgery are retrospectively reviewed. Results: Facial morphology was satisfactory in 7 patients who had all tumor removal by a type 1 or 2A maxillectomy and surgical wound closure. Out of these patients, 4 who had dental rehabilitation by conventional prosthesis presented satisfactory mastication. Four patients subjected to the tumor removal by a type 3 maxillectomy had all facial asymmetry. Out of these, 1 patient who did not have the orbital floor defect repair presented diplopia and enophtalmos, 2 patients subjected to the palate defect repair by a prosthetic obturator or oral mucosa had elocution impairment. The tumor recurrence occurred in 2 patients after tumor enucleation and in 1 patient after radical surgery out of 8 patients who had ...
Segmental Mandibular Resection for Conventional Ameloblastoma
2021
Ameloblastoma is an aggressive slow growing benign epithelial odontogenic tumor usually associated with an unerupted third molar. In this report, we present the case of a 71-year-old male with a large swelling on the left mandibular region causing a remarkable facial asymmetry. After clinical, radiological, and histopathological examinations the diagnosis of conventional ameloblastoma was made. To avoid probable recurrence our treatment choice was a segmental mandibular resection with the placement of a reconstructive titanium plate to maintain the space for subsequent bone graft.
Maxillary ameloblastomas: a review of the literature and of a 15-year database

were evaluated. Patients: Twenty-six patients suffering from ameloblastoma had been collected. Five of them, had a maxillary ameloblastoma, three females and two males. Methods: A clinical retrospective study was performed. In addition a review of the literature was undertaken and the findings have been compared and contrasted. Patients: The overall incidence of ameloblastoma within the mandible (21) was four times higher than in the maxilla (5). In 69 per cent of the cases (18) it occurred in men, in 31 percent (8) in women. The sex ratio differed with the maxillary ameloblastomas: 40 percent male (2) and 60 per cent female (3). Although slow growing and nearly painless, it can reach a considerable size within the mid-face involving such highly specialized structures as the orbit, skull-base and brain. Wide resections with a safety margin of healthy bone to prevent local recurrence were undertaken. Nevertheless, recurrence was frequent due to invasion of the adjacent bone. Conclusion: On the one hand, a recurrence was found after a simple curettage of a 'dental cyst'. On the other hand, extensive bone destruction, involvement of the nasal cavity, the ethmoidal and sphenoidal sinuses, infiltration of the skull-base and distant metastasis were observed. The current treatment of choice is partial maxillectomy with a 10-15 mm safety margin of healthy bone including the alveolar ridge, the hard palate, the mucosa of the maxillary sinus and the lateral nasal wall. For the removal of tumours close to or invading the retromaxillary space the temporal approach gives ample access.

ABSTRACTBackground: Ameloblastoma is the most common odontogenic tumor. Ameloblastoma is a borderline tumor because it is a benign but locally aggressive tumor with a high recurrence rate if the excision is not complete. The principle of treatment for ameloblastoma is excision all the tumor. This article aimed to conduct a retrospective study to analyze the characteristics of ameloblastoma in patients at Oral and Maxillofacial Surgery Hasan Sadikin Hospital Oral Surgery between the period of January 2018-December 2019Method: This is a retrospective study with 37 patients diagnosed with ameloblastoma during 2018-2019. We took data from each patient such as gender, age, radiological features, histopathological diagnosis of the location of ameloblastoma, management, defects, reconstruction. Result: A total of 22 patients were diagnosed with plexiform ameloblastoma, 12 cases of follicular ameloblastoma, 3 cases of mixed plexiform and follicular ameloblastoma. 31 patients were treated ra...
