ABSTRACT

ABSTRACT: Ankylosis of the temporomandibular joint is a disorder resulting from fibrous, osseous, or fibro-osseous adhesion that directly affects the quality of life of the individual. The authors present a case of unilateral temporomandibular joint ankylosis treated by condilectomy and ipsilateral sliding vertical ramus osteotomy associated with contralateral sagittal osteotomy aiming to restore function and to correct dentofacial deformity class II. A 31-year-old female patient presented with a history of facial trauma and major complaint of oral opening limitation. Physical examination revealed hypoplasia of the lower third of the face, facial pattern type II, anterior open bite, and maximum mouth opening of 22.5 mm. Computed tomography showed an ankylotic mass in the right mandibular condyle with deformity of the condylar structure and fusion to the right zygomatic arch and a contralateral condylar fracture sequel. It was proposed to perform a condilectomy of the right mandibular condyle for the removal of the bone mass concomitant to the sliding vertical ramus osteotomy of the mandibular ramus for condylar reconstruction by rhytidectomy approach and the sagittal osteotomy of the left mandibular aiming the reestablishment of occlusion and the correction of dentofacial deformity. The condylar fracture was not operated because the condyle was remodeled. The patient is in her fourth year postoperative presenting satisfactory esthetic-functional re-stabilization, without clinical signs of recurrence. In conclusion, the authors believe that combined sliding vertical ramus osteotomy and sagittal osteotomy can bring satisfactory results in complex cases.

ABSTRACT

Objective: To investigate the prevalence of calcified triticeous cartilage (CTC)-compatible images on digital panoramic radiographs of a significant Brazilian population sample. Methods: In this retrospective study, 2500 digital panoramic radiographs were analyzed by a trained examiner using contrast and brightness adjustments of the Adobe® Photoshop® CC 2015 software. Data were collected and exported for statistical analysis (p-value <0.05 was considered statistically significant). Results: The prevalence of CTC-compatible images was 4.5% (61.1% in women and 38.9% in men). The most prevalent age ranged between 51 and 60 years (32.7%), and bilateral occurrence had a higher prevalence (46.9%). Women between the ages of 61 and 70 years showed a significantly higher prevalence of CTC-compatible images (p=0.027). Conclusion: This study showed a low prevalence of CTC-compatible images, which mainly occurred in women close to 70 years of age.


Objetivo: Investigar a prevalência de imagens compatíveis com calcificação da cartilagem tritícea (CCT) em radiografias panorâmicas digitais de uma significante amostra populacional brasileira. Métodos: Neste estudo retrospectivo, 2500 radiografias panorâmicas digitais foram analisadas por um examinador treinado utilizando ajustes de contraste e brilho através do software Adobe® Photoshop® CC 2015. Os dados foram coletados e exportados para análise estatística (p<0,05 foi considerado como valor estatisticamente significante). Resultados: A prevalência de imagens compatíveis com CCT foi de 4,5% (61.1% em mulheres e 38.9% em homens). A idade mais prevalente variou entre 51 e 60 anos (32,7%), sendo a ocorrência bilateral a mais comum (46,9%). Mulheres com idade entre 61 e 70 anos apresentaram prevalência significativamente maior de imagens compatíveis com CCT (p=0,027). Conclusão: O presente estudo evidenciou uma baixa prevalência de imagens compatíveis com CCT, que ocorreram, principalmente, em mulheres com idade próxima aos 70 anos.

ABSTRACT

BACKGROUND: The aim of the present study was to analyze the epidemiological data of digital panoramic radiographs revealing suggestive images of carotid artery calcifications (CAC) from a Northeast Brazilian population. MATERIAL AND METHODS: A cross-sectional retrospective study was conducted with 2,500 digital panoramic radiographs obtained from a single imaging reference center in Northeast Brazil. Images from individuals of both sexes and older than 18 years were included and those that did not cover the region of cervical vertebrae or presented low radiographic quality were excluded. Data were analyzed regarding prevalence, location (bilateral, right or left), sex, and age using the Chi-square test at the significance level of 5%. RESULTS: An amount of 96 (4%) patients presented suggestive images of CAC. The female sex (p = 0.003) and individuals aged up to 70 years (p = 0.002) were statically significant. 40.4% were found bilaterally, 37.6% on the right side (p < 0.001) and 22% on the left side. CONCLUSIONS: In conclusion, this study showed a low prevalence of suggestive images of CAC in digital panoramic radiographs from a Northeast Brazilian population. It was observed a higher prevalence of CAC associated with female sex, older patients, and right side location
