BackgroundAn osteoma is a benign tumor of bone with unknown etiology and is considered rare, mostly restricted to the craniofacial skeleton.Case presentationThis case report describes an uncommon condylar osteoma in a 67 years old white female patient with laterognathism to the left side, limited mouth opening, aesthetic change and pain associated with the right temporomandibular joint (TMJ). The histopathological examination confirmed osteoma. The lesion was surgically excised and immediate reconstruction was carried out using a custom-made total TMJ prosthesis. The patient has been in follow-up for 2 years, with no symptoms.ConclusionsUnilateral total TMJ prosthesis can be considered to replacement of TMJ after osteoma excision with resection of the condyle.
In the city of Rio de Janeiro, young men in their fourth decade of life are prone to trauma to their facial bones, especially the mandible, and they are most commonly caused by traffic accidents.
to evaluate the frequency of keratocystic odontogenic tumor (KOT) in the Oral Surgery Service (OSS) of the University Hospital Clementino Fraga Filho of the Federal University of Rio de Janeiro (HUCFF / UFRJ), with respect to recurrence rate, gender, age of recurrence and location of the injury Methods: clinical records were reviewed and histopathological reports of KOT patients of the HUCFF/UFRJ between 2002 and 2012. Patients diagnosed with KOT were divided into two groups for the occurrence of relapse: positive (n=6) and negative (n=19) Results: regarding the location, there was a predilection for the mandible. In the average age of patients in the positive group was 40.5 and the negative group, 35.53. In the distribution by gender, positive group showed equal distribution, different from that observed in the negative group, which showed a predilection for males Conclusion: KOT was the second most frequent injury in our patients, recurrence was lower among males and had the jaw as most affected location.
Objective: tthis paper reports a case of osteonecrosis of the jaws associated with the use of intravenous bisphosphonates (BRONJ) after extraction of the maxillary right first and second molars. Case report: a 53-year-old male patient with diagnosis of multiple myeloma undergoing treatment at Arthur Siqueira Cavalcanti Institute (HEMORIO) with intravenous bisphosphonate (zoledronic acid), performed dental extractions in a private clinic. Approximately one month later, he complained of pain at the dental extraction site and was referred by the oncologist to the hospital's dental service. Intraoral clinical examination revealed an extensive area with characteristics of bone necrosis and the panoramic radiography revealed a radiolucent area suggestive of bone sequestration. The combination of clinical and radiographic findings confirmed the diagnosis of bisphosphonate-related osteonecrosis of the jaws (BRONJ). Conclusion: patients under regular continuous use of bisphosphonates must be warned of the possible development of BRONJ after invasive dental procedures and proper guidance must be provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
