Conservative Surgical Approach to Odontogenic Myxoma Involving Anterior Maxilla: A Case Report

A rare, benign odontogenic tumour - Odontogenic myxoma has a locally aggressive behavior, and is relatively rare in the maxilla. A variety of surgical approaches for this type of tumour have been tried but no clear-cut management protocol has been defined. This case addresses the surgical management of odontogenic myxoma and its behavior in the clinical setting.

Rehabilitation of Maxillary Defect Using Zygomatic Implant Retained Obturator

Tumors involving the hard palate, maxillary sinus, or nasal cavity require maxillectomy based on the extent of the lesion. Lack of these boundaries affects the speech, esthetics, and masticatory function. Prosthetic rehabilitation of these defects can be done utilizing zygomatic implants. This present case describes the use of a zygomatic implant to retain a maxillary obturator in a 22-year-old male patient following partial maxillectomy (Brown’s Class 2b) due to odontogenic myxoma. A surgical obturator was secured in position subsequent to the implant placement. Following the healing period, an interim obturator using heat cure acrylic was fabricated. Mechanical retention for the definitive obturator was obtained through the ball attachment suspended from the multiunit abutment of the zygomatic implant. The case was followed up closely for a year to evaluate the function of the prosthesis. The prosthetic rehabilitation not only promoted esthetics and function but also improved the patient’s quality of life.

Central Odontogenic Myxoma: A Radiographic Analysis

Objective. This study aimed to determine the radiographic characteristics of odontogenic myxomas (OMs) and their associations. Materials and Methods. The study enrolled radiographs of patients taken between 2005 and 2019 with a confirmed histopathological diagnosis of central OM. OM radiographic features were evaluated, including location, border, locularity, involved area, the number of included teeth, root resorption, tooth displacement, bone expansion, bone perforation, and periosteal reaction. Fisher’s exact test was used for statistical analysis. Results. Significant associations were found between the OM border and the affected jaw ( p = 0.036 ), locularity ( p = 0.036 ), involved areas ( p = 0.009 ), and bone perforation ( p = 0.036 ). OMs with an ill-defined border were associated with maxillary lesions, multilocularity, dentate areas, and cortical bone perforation. The number of included teeth (2 or fewer or 3 or more) was significantly associated with locularity ( p = 0.010 ), involved area ( p = 0.045 ), and bone expansion ( p = 0.010 ). Larger OMs including 3 or more teeth, were associated with a multilocular appearance, dentate areas, and bone expansion. Conclusion. The border of OM and the number of included teeth are related to other radiographic appearances. Understanding these relationships could help in treatment decisions and help better understand the nature of OM.

Odontogenic Myxoma of the Anterior Mandible: Case Report of a Rare Entity and Review of the Literature

We report a case of a 38-year-old female patient with odontogenic myxoma who was referred to us with chief complaint of a persistent painful lesion and teeth mobility in the anterior region of the mandible which had underwent a faulty treatment plan in an outside clinic.

Peripheral odontogenic myxoma: Clinical case with a literature review

Peripheral odontogenic myxoma (POM) is a rare and extra-osseous variant of odontogenic myxoma (OM), classified as a relatively rare benign odontogenic tumor, yet presenting locally aggressive behavior. The objective this manuscript is to report a case of POM in a 75-year-old patient, located in the right maxilla, and in addition, to perform a literature review of the data in relation to clinical, radiographic aspects, hypothesis of diagnosis, and treatment. A male patient, 75 years old, clinical examination constact the presence of a nodule, with a smooth surface, on the right upper alveolar ridge, measuring 20 x 25 mm, with a color similar to the mucosa, a softened consistency, involving teeth 14 and 15, and with an undetermined time of evolution was observed. The diagnostic hypothesis was a peripheral ossifying fibroma and differential diagnosis of peripheral giant cell lesion. An excisional biopsy was performed together with extraction of the involved teeth. Histopathological examination and histochemical reaction was confirm the histopathological diagnosis of POM. The reported case is extremely rare due to the clinical presentation of the lesion, causing bone resorption with tooth mobility. In addition, the age range of involvement is very different from that presented in the literature, between the second and fourth decade of life. The final diagnosis was very important, as it is a lesion with a great potential for recurrence, long-term follow-up should be more careful, and in case of recurrence, a new intervention must be performed.
