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%).

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...
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 ...

Aim: The purpose of this study is to evaluate the incidence, radiological features, histological variant, and different treatment options of patients with ameloblastoma of the jaws treated at a tertiary-level hospital in Bangladesh. Materials and Methods: Age, gender, tumor location, radiologic features, histological pattern, and treatment modalities were all evaluated in this retrospective observational study. The frequency and percentages of these study variables were analyzed using descriptive statistics. Results: A total of 131 patients were included in this study, 66 of them were female, with a male-to-female ratio of 1:1.01. The patients had a wide age range from 4 to 70 years, a mean age (±standard deviation) of 26.61 (±13.34) years, and a significant incidence in the third decade of life. The left side of the jaws was the most frequently involved site. The mandible (n = 125, 95.42%) was the most frequently affected site, with the body-angle-ramus (n = 73, 58.5%) area being the most frequently involved location. Multilocular radiolucency was seen in most cases (n = 73, 55.73%) on radiography. The most common histological pattern (n = 71, 54.2%) was follicular. The most preferred treatment was the dredging (n = 90, 68.70%) method. The recurrence rate of the dredging treatment method was 5.56%. Conclusions: Ameloblastoma was found to be more common in patients in their third decade of life, with a wide age range. The follicular ameloblastoma was the predominant histological type, with most of them occurring in the mandible's body-angle-ramus area. Most of the patients were treated by the dredging method.
Radical management of solid ameloblastoma of the mandible: Report of a case with 5-year follow-up
Head & Neck Oncology
Ameloblastoma is a true neoplasm of odontogenic epithelial origin. This pathology can be classified into 4 groups: unicystic, solid or multicystic, peripheral, and malignant. Solid ameloblastomas of the mandible are the most common of them, and represent a challenging group of tumours to treat; in addition the follicular histopathological subtype has a high likelihood of recurrence. Thus, the challenges in the management of this tumour are to provide complete excision in addition to reconstruct the bony defect, in order to provide the patient with reasonable cosmetic and functional outcome. With this in mind, this paper aimed to describe the management of a solid multilocular ameloblastoma of follicular subtype in a 39-year-old female. Case report The authors report a case of a solid multilocular ameloblastoma of follicular subtype in a 39-year-old female who was successfully treated by partial resection of the mandible with immediate reconstruction using an iliac crest, as a donor ...

Ameloblastoma is a rare, benign, odontogenic tumor of epithelial origin, characterized by locally aggressive, expansive growth. Treatment is controversial due to the risk of relapse. The aim of this multicenter retrospective study was to evaluate the effectiveness of complete resection in cases of complex ameloblastoma, which is considered at a higher risk of recurrence. Patients who met at least one of these criteria were included: recurrence, soft-tissue involvement, complete erosion of internal/external cortical walls with involvement of the inferior margin of the mandible, and invasion of the maxillary sinus or nasal cavity. Demographic data, tumor site, type of surgery, histological features, and follow-up information were collected for each patient. The cohort included 55 patients with a mean follow-up of 108 ± 66 months. A multivariate logistic model was used to evaluate variables independently associated with relapse. There were six soft-tissue or maxillary sinus relapses, w...

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.
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 ...
