“…The body of the mandible is usually affected (75%) in the premolar and molar regions, with a possible, and sometimes important, posterior extension. 6,7 In both cases, SBC is diagnosed predominately in the first 2 decades of life (75%). The maxillomandibular location is distributed almost equally between the genders, although there is a male predominance for the extrafacial variants.…”

“…The pressure from the hema- toma causes venous stasis that leads to an area of bone marrow necrosis 2,15,26 and osteoclastic resorption attributable to decreased tissue pH. 27,28 In the mandible, trauma also might provoke a thrombosis or a lingering spasm of a terminal artery with ischemia and aseptic necrosis, thereby leading to cyst formation. Vascular alterations are supposedly related to the resorption phenomena.…”

Solitary bone cysts (SBCs) of the jaws are often polymorphic, show scalloped borders when located between the teeth roots, are devoid of an epithelial lining, and are usually empty or contain blood or a straw-colored fluid. The numerous synonyms referring to these lesions reflect their uncertain nature (eg, traumatic bone cyst, simple bone cyst). SBC, also found in other skeletal locations, is often suspected after epidemiologic and radiologic test results and confirmed at surgery. Histology usually shows fibrous connective tissue or only bone. The various etiologic elements responsible for SBC include tumor degeneration, trauma, or abnormalities during bone growth. The pathogenesis of the SBC is unknown, but it is widely accepted that it could be the result of a vascular dysfunction leading to a local posthemorrhagic ischemia, inducing an osseous aseptic necrosis. This article reviews likely but stilldebated etiopathogenic hypotheses of lesions of the jaws and other, more frequent bony locations, such as the humeral and femoral metaphysis.

“…Cette théorie s'appuie sur l'apparition d'une hémorragie intramédullaire suivie d'un hématome après un traumatisme insuffisant pour provoquer la fracture d'un os sain. La pression exercée par l'hématome entraînerait une stase veineuse favorisant la nécrose de la moelle osseuse [2,20,31], la résorption ostéoclasique serait stimulée par la diminution du pH tissulaire [32,33].…”

“…La localisation maxillo-mandibulaire est bien moins fréquente. En effet, dans les séries de lésions kystiques étudiées, la fréquence du KOS des maxillaires varie de 0,5 à 1,0 % avec une atteinte préférentielle, géné-ralement unilatérale, de la mandibule (75 % des cas) et le siège de prédilection [6,7] est constitué par la région antéro-moyenne du corps de la mandibule avec des extensions lé-sionnelles postérieures parfois importantes. Dans ces deux localisations squelettiques, le diagnostic de KOS est établi au cours de l'enfance et de l'adolescence.…”

Mots clés : kyste osseux solitaire / radiographie / pathogénieRésumé -Le kyste osseux solitaire des maxillaires est constitué par une lésion ostéolytique, sans paroi épithéliale et au contenu variable selon le site osseux. Il réalise, dans sa localisation maxillaire, une cavité osseuse de forme géodique dont l'aspect radiologique est très souvent polymorphe. L'approche diagnostique de cette pseudo-tumeur osseuse bénigne ne repose en fait que sur la symptomatologie peu évocatrice, quelques caractéristiques sémiologiques en radiographie standard, la découverte peropératoire d'une cavité vide et l'analyse histologique qui montre l'absence de bordure épithéliale. Parfois, l'extension de la lésion lui donne un aspect très polymorphe et ouvre l'interprétation radiographique à un diagnostic différentiel très large. Une synthèse des connaissances cliniques acquises à travers les localisations osseuses maxillomandibulaires et les localisations métaphysaires humérales et fémorales, beaucoup plus fréquentes, permet de discuter les principales hypothèses étiologiques émises concernant un processus pathogène qui semble varier selon les sites osseux affectés, le mode d'apparition, l'évolution et les réponses aux thérapeutiques médico-chirurgicales proposées. Key words: solitary bone cyst / radiography / pathogenesisAbstract -Solitary bone cyst of the jaws: radiographic features and pathogenesis. The solitary bone cyst of the jaws is an osteolytic lesion, devoid of an epithelial lining, with a content that varies according to the affected skeletal site. It appears as a unilocular cavity but often with a polymorphic radiological aspect. The diagnosis of this pseudo-cyst is mainly based on poor symptomatology, some radiological features on standard X-ray examinations, and the intraoperative finding of an empty cavity along with the absence of an epithelial covering at microscopy. Occasionally, the extent of the lesion produces a polymorphic pattern, which gives rise to a wide array of differential diagnoses. The aim of this paper is to summarize clinical knowledge in relation to both jaws as well as much more frequently observed femoral and humeral metaphyseal locations, and to discuss the main etiologic hypotheses based on presentation, evolution and therapeutic approaches which apparently vary according to the involved site.Pour designer le kyste osseux solitaire (KOS), on a utilisé une terminologie très variée, parfois énigmatique (kyste idiopathique, kyste essentiel, kyste osseux simple) ou qui traduit le processus étiopathogénique suspecté (kyste osseux traumatique, hémorragique ou hématique, ostéodystrophie kystique). Cela démontre que le KOS des maxillaires reste encore une lésion très mal connue.Dans notre spécialité, le KOS est classé parmi les bonerelated lesions dans les tumeurs odontogènes des maxillaires [1]. Il est défini par une lésion ostéolytique se

Objectives: The aim of this study was to evaluate the demographics and characteristics of the patients treated for traumatic bone cyst (TBC). Materials and Methods:A retrospective review was conducted to determine the radiological, clinical and demographic characteristics of patients with TBC who were surgically treated over a 2-year period using data retrieved from computerized databases. Results:The study sample consisted of 22 patients (24 lesions in total) with mean age of 22.9 years. All lesions were located in the mandible (16 in anterior mandible, 8 in posterior mandible) and diagnosed incidentally during routine dental examinations. There was no statistically significant difference between male and female patients in demographic characteristics. All patients were followed up for 6-18 months with uneventful healing. Conclusions:TBCs should be kept in mind during examination of radiolucent lesions of the mandible particularly in younger patients. Along with the histopathological examination, clinical and radiological findings, symptoms of the patients, and surgeon's experience should be considered for a definitive diagnosis.
