“…Nelson (2010), states that the main location for mandibular SBC is the premolar and molar regions, followed by the mandibular symphysis. The present study found one lesion in the condyle, a rare event, with just over 16 cases reported (Hatakeyma et al, 2012;Kretzschmar, Postma, & Inman, 2005;Kyoung & Kwang, 2013;Magliocca et al, 2007).…”

“…Scalloping around the adjacent teeth is a common finding in SBCs cases (Bhoosreddy et al, 2010;Cortell-Ballester et al, 2009;Kumar et al, 2011;Nelson, 2010;Velez et al, 2010), though root resorption is rare (Kumar et al, 2011;Borgonovo et al, 2012;Velez et al, 2010). Although the vitality of the dental pulp is rarely affected (Magremanne et al, 2009;Velez et al, 2010), response to vitality testing can be temporarily reduced due to the expansion of the lesion and increased pressure around the roots (Hatakeyma et al, 2012). In this study, five patients (55.56%) showed interradicular scalloping, while Copete et al (1998) found that 30 out of the 44 cases (68%) showed the same pattern.…”

“…A CT scan can confirm the phenomenon and show whether the cavity is empty or fluid-filled, which helps the differential diagnosis (Hatakeyma et al, 2012). Because conventional xrays are not able to show expansion of the cortical bone, it was believed that SBCs did not cause it.…”

ABSTRACT. To present further information about SBCs based on a retrospective study of 12 cases, by describing their clinical and radiographic characteristics, and comparing them with recent findings. The study examined SBCs from the Projeto Lesões Bucais 'treatment and epidemiology of diseases of the oral cavity', run at State University of Maringá, Paraná State, Brazil, between 1995 and 2014. Twelve cases were found among the records of 2.424 patients who had been submitted to different types of biopsy. All cases occurred in the mandible, predominantly in patients in the second decade of life, in the region posterior to canines, and among women. All lesions were solitary, 75% of them unilocular. Helicoidal CT showed expansion and rupture of the cortical bone in one case. Differential diagnosis was confirmed by means of histopathological examination. Treatment consisted of surgical exploration in all cases. Most SBCs are usually asymptomatic and diagnosed by chance on routine X-ray examination. However, SBC can cause bone expansion or bone rupture, only visible with more sophisticated imaging systems. This study showed that the diagnosis of SBC benefits with the use of conventional radiography and CT, associated with careful clinical examinations.Keywords: bone cysts. spiral computed tomography. cone-beam computed tomography . radiography. diagnosis.Cisto ósseo solitário: uma análise de 12 casos RESUMO. Apresentar informações adicionais sobre o COS a partir da revisão de 12 casos, com a descrição das características clínicas e radiográficas, comparando-as com a literatura recente. Realizou-se um estudo retrospectivo observacional de casos de COSs apresentados por pacientes do projeto de extensão: 'Diagnóstico, tratamento e epidemiologia das doenças da cavidade bucal -Lebu', da Universidade Estadual de Maringá -Paraná, Brasil, entre os anos de 1995 e 2014. Dos 2.424 prontuários de pacientes que foram submetidos a diferentes tipos de biópsia, 12 casos de COS foram encontrados e selecionados para pesquisa. Todos os casos ocorreram na mandíbula, preferencialmente em pacientes jovens na segunda década de vida. Ocasionalmente, a expansão da tábua óssea cortical foi notada e, por meio de exame histopatológico, o diagnóstico da lesão foi confirmado. A maioria dos COS são, geralmente, assintomáticos e diagnosticados por acaso em exames radiográficos de rotina. No entanto, o COS pode causar expansão óssea ou rompimento de cortical óssea, visível apenas com métodos de imagem mais sofisticados. O presente trabalho de pesquisa mostrou que o diagnóstico de COS é beneficiado pelo uso da radiografia convencional e tomografia computadorizada, associada a exames clínicos cuidadosos.Palvras-chave: cistos ósseos. tomografia computadorizada espiral. tomografia computadorizada de feixe cônico. radiografia diagnóstico.

“…When cortex of the condyle head is exposed, needle aspiration would be useful to identify contents of the lesion13. If preoperative diagnosis is assumed to be a TBC, an intraoral endoscopic approach as a minimally invasive surgery would be useful for surgical exploration and cosmetic outcome1415. Minimally invasive surgery is recommended to prevent accidental or pathologic condyle fracture after surgery.…”

Traumatic bone cyst (TBC) occurs preferentially on the mandibular symphysis and body, but rarely on the mandibular condyle. When TBC occurs in the condylar area, it can usually be related with or misdiagnosed as a temporomandibular joint disorder. A 15-year-old female patient visited the Temporomandibular Joint Clinic with a 5-year history of pain and noise localized in the left temporomandibular joint. On imaging, a well demarked oval-shaped radiolucent lesion was observed on the left condyle head. The patient underwent cyst enucleation and repositioning of the bony window on the lateral cortex of the affected condyle head under the impression of subchondral cyst or TBC; however, no cystic membrane was found. The bone defect resolved and showed no recurrence on the serial radiographic postoperative follow-up for 43 months after surgery.
