RESUMO
OBJECTIVE: The surgical treatment of Eagle syndrome involves an intra- or extraoral approach. This systematic review set out to consolidate current knowledge on the prevalence of complications associated with intraoral and external approaches. METHODS: Seven main electronic and two gray literature databases were searched. Studies were blindly selected by two reviewers based on pre-defined eligibility criteria. Studies evaluating any type of complication in the treatment of Eagle syndrome were considered eligible. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for studies reporting prevalence data, case reports, and case series. The Comprehensive Meta-Analysis software (Software version 3.0 - Biostat, Englewood, NJ, USA) was used to perform all meta-analyses. RESULTS: Out of 1728 articles found on all databases, 36 were included for qualitative analysis. Twenty were included for quantitative analysis and meta-analysis. CONCLUSION: In this study, the highest rate of complications was found in the intraoral approach.
RESUMO
PURPOSE: This study was performed to investigate mandibular canal displacement in patients with ameloblastoma using a 3-dimensional mirrored-model analysis. MATERIALS AND METHODS: The sample consisted of computed tomographic scans of patients with ameloblastoma (n=10) and healthy controls (n=20). The amount of mandibular canal asymmetry was recorded as a continuous variable, while the buccolingual (yaw) and supero-inferior (pitch) directions of displacement were classified as categorical variables. The t-test for independent samples and the Fisher exact test were used to compare groups in terms of differences between sides and the presence of asymmetric inclinations, respectively (P<0.05). RESULTS: The length of the mandibular canal was similar on both sides in both groups. The ameloblastoma group presented more lateral (2.40±4.16 mm) and inferior (-1.97±1.92 mm) positions of the mental foramen, and a more buccal (1.09±2.75 mm) position of the middle canal point on the lesion side. Displacement of the mandibular canal tended to be found in the anterior region in patients with ameloblastoma, occurring toward the buccal and inferior directions in 60% and 70% of ameloblastoma patients, respectively. CONCLUSION: Mandibular canal displacement due to ameloblastoma could be detected by this superimposed mirrored method, and displacement was more prevalent toward the inferior and buccal directions. This displacement affected the mental foramen position, but did not lead to a change in the length of the mandibular canal. The control group presented no mandibular canal displacement.
RESUMO
Dental implant surgery is a common procedure in oral and maxillofacial surgery practices. Extensive training, skill, and experience allow this procedure to be performed with an atraumatic approach, but like any surgical technique, it is subject to accidents and complications. This is an unusual clinical case of an accidental displacement of an implant into the submandibular space that progressed to Ludwig's angina, and it has not yet been described in the literature. This case report describes a clinical case of dental implant displaced into the submandibular space after healing cap removal. After seven days, it progressed to Ludwig's angina. The removal was performed through extraoral access in the submandibular area by using hemostatic forceps and radioscopic technique. After implant removal, the clinical case showed a satisfactory repair emphasizing the importance of a meticulous clinical planning to achieve an appropriate treatment plan, which is essential for a favorable prognosis. Therefore, prevention and management of displaced objects requires proper planning and surgical technique.
RESUMO
Glandular odontogenic cyst (GOC) is an uncommon cyst of the jaw. Less than 200 cases are reported in the literature, and only 22 cases are associated with an unerupted tooth (dentigerous relationship). Although it is an asymptomatic lesion, it can be destructive and has high recurrence rates. The diagnosis can be especially challenging due to the lack of distinct diagnostic clinic-radiological criteria and nonspecific microscopic features, mimicking benign and malignant lesions. Conservative surgical treatment has been the choice for most surgeons, but marginal or partial jaw resection has been reported. This report describes a rare case of GOC in a dentigerous relationship, which was treated with enucleation and peripheral osteotomy.

Os autores fazem uma descriçäo de caso clínico de reconstruçäo de fenda alveolar, com enxerto ósseo secundário, em criança de 13 anos, tendo como leito doador a mandíbula (mento e ramo) e a associaçäo deste enxerto ao Plasma Rico em Plaquetas (PRP). Säo discutidas as indicaçöes da reconstruçäo óssea secundária, as vantagens do uso do osso mandibular (mento e ramo) como área doadora e as melhoras no processo de reparo ósseo produzidas pelo PRP
