... (13) The explanation underlying the hypothesis of trauma (14) according to this theory TBC arises from a focus of intramedullary hemorrhage that causes a hematoma after trauma. (15) This hematoma subsequently liquefies and fails to organize and be replaced with tissue. (16) The other theories assert failure of growth and development of osseous tissue, biochemical and mesenchymal differentiation, degeneration of benign neoplasms and low-grade infection. ...
... (27) Most of times this lesion is asymptomatic and discovered on routine radiographic examination only. (28) However, dull pain is associated in 10-30% of the patients, (7)(8)(9)(10)(11)(12)(13)(14)(15) swelling, tooth sensitivity, and less commonly with fistula, root resorption, paresthesia, displacement of inferior alveolar canal, (29) delayed eruption of permanent teeth. Cortical plate expansion is seen in some cases, which occurs commonly on buccal side and pathological fracture of the mandible. ...

The traumatic bone (TBC) cyst is an uncommon benign empty or fluid containing cavitywithin bone that is not lined by epithelium. The etiopathogenesis of TBC is still unknown. TBCis frequently encountered in young patients during the second and third decades of life. Sexpredilection is equal but some studies in literature suggest clear female predominance. Body of themandible between the canine and the third molar is the most common site (75%) in head and neckregion followed by mandibular symphysis. The cysts are usually asymptomatic. Associated teethare usually vital with no resorption or displacement. It expands the cortices and, seldom, intraoral orextra oral swelling may be seen. Most of the TBCs are diagnosed incidentally in orthopantomogram(OPG). On radiographic examination, a unilocular irregular but well defined lytic lesion is seencharacteristically extending between the roots of the teeth. TBC is representing approximately1% of all jaw cysts. A final diagnosis of a TBC is almost invariably made at the time of surgery,where in identification of an empty air-filled cavity serves as a valuable diagnostic tool. Surgicalexploration was proved not only essential in making the right diagnosis but also curative from atreatment plan perspective. Recurrence of TBC is assumed to be extremely rare. However, a distinctproportion of recurrences may occur. (2) (PDF) TRAUMATIC BONE CYST OF THE MANDIBLE; DIAGNOSTIC CHALLENGE AND MANAGEMENT A CASE REPORT.

Idiopathic Bone Cavity (IBC) or Simple Bone Cyst (SBC) is a non- epithelialized bone cavity with serosanguinous fluid content or empty. There is a literature debate regarding its pathogenesis that remains unclear. The main treatment option is the surgical exploration, although there are successful cases described in the literature in which just a follow-up with clinical and radiographic evaluation was performed. Objective This study aimed to assess the spontaneous resolution of idiopathic bone cavity untreated by surgery. Material and Methods Twenty-one patients diagnosed with surgically untreated IBC were submitted to a follow-up protocol modified from Damante, Guerra, and Ferreira⁵ (2002). A clinical and radiographic evaluation was performed in 13 patients (13/21), while eight patients (8/21) were only radiographically evaluated. Three observers evaluated the panoramic radiographs of 21 patients and the Kappa test was performed by intra and inter-examiners. Inductive and descriptive statistics were applied to the results. Results Only one patient had a positive response to palpation and percussion of the teeth in the cyst area. Most of the cysts evaluated were rated as 3 (lesion “in involution”), 4 (lesion “almost completely resolved”), or 5 (“completely resolved”). Conclusions We observed progressive spontaneous resolution of IBC. Most cysts were found in the recovery process in different follow-up periods. Patient's follow-up, without surgery, may be considered after the diagnosis based on epidemiological, clinical, and radiographic features of the lesion.

Solitary bone cysts (SBCs) are bone cavities that lack a true epithelial lining. They are more commonly seen during the first 2decades of age.Very few cases have been reported over 40 years of age.SBCs are usually discovered as an accidental coexisting finding during a routine radiologic examination or during another unrelated dental complaint. They present as a unilocular or multilocular radiolucent lesion associated with vital teeth with mild or no cortical expansion. Bilateral presentation is however very rare. We present a case of 52-year-old female patient with bilateral presentation of SBCs.

Abstract The traumatic bone cyst (TBC) is an uncommon nonepithelial lined cavity of the jaws. The lesion is mainly diagnosed in young patients most frequently during the second decade of life. The majority of TBCs are located in the mandibular body between the canine and the third molar. Clinically, the lesion is asymptomatic in the majority of cases and is often accidentally discovered on routine radiological examination usually as an unilocular radiolucent area with a "scalloping effect". The definite diagnosis of traumatic cyst is invariably achieved at surgery. Since material for histologic examination may be scant or non-existent, it is very often difficult for a definite histologic diagnosis to be achieved. We present a well documented radiographically and histopathologically atypical case of TBC involving the ramus of the mandible, which is also of possible iatrogenic origin. The literature is briefly reviewed.

To describe the clinical and radiological characteristics, and surgical findings of traumatic bone cysts. A retrospective observational study was made of 21 traumatic bone cysts. The diagnosis was based on the anamnesis, clinical exploration, and complementary tests. Panoramic and periapical X-rays were obtained in all cases, together with computed tomography as decided by the surgeon. A descriptive statistical analysis was made of the study variables using the SPSS v12.0 for Windows. There was a clear female predominance (14:7). The mean age was 26.5 years (range 8-45 years). The cysts in all cases constituted casual findings during routine radiological exploration. In those cases where computed tomographic images were available, preservation of the vestibular and lingual cortical layers was observed. Five of the 21 patients (23.8%) reported a clear antecedent of traumatism in the affected zone. All the lesions were subjected to surgery, and the cavities were found to be vacant in 90.5% of the cases. In only two patients were vascular contents seen within the cavity. Two of the patients presented postoperative paresthesia of the inferior dental nerve that subsided within two weeks. The 19 patients in whom adequate postoperative follow-up proved possible all showed complete bone healing. Traumatic bone cysts were a casual finding. During the surgery, most cases showed to be vacant cavity without an ephitelial lining. Careful curettage of the lesion favors progressive bone regeneration, offering a good prognosis and an almost negligible relapse rate. Other treatment options only would be justified in cases of relapse.

Background The solitary bone cyst is an uncommon nonepithelial cyst. Clinically, the lesion is asymptomatic in the majority of cases and is often accidentally discovered on routine radiological examination, frequently during the second decade of life. Its pathogenesis is still not clearly understood. The majority of solitary bone cysts are located in the mandibular body. This article presents two case reports, one in whom a cyst was diagnosed on routine radiographic examination and other patient reported with dull ache and radiographic examination showed bilateral presentation of the cystic lesion. Materials and methods In both patients the biopsy was planned. On surgical opening the lesions presented empty cavities. Curettage was done and overlying bone sent for histopathological examination. Both patients were followed for 1 year. Results At follow-up visit both patients were examined clinically and radiographically. In both the patients resolution of the lesion was seen at follow-up visit. Conclusion Solitary bone cyst is a rare entity with typical clinical and radiographic features. However, confirmation of diagnosis can be made only by histological examination. Solitary bone cyst may be secondary to an underlying bone pathology. Solitary bone cyst of the head and neck may vary in presentation and severity. Surgical removal is the treatment of choice and provides a satisfying outcome.

The term ‘solitary bone cyst’ defines several lesions such as simple bone cyst, hemorrhagic cyst, traumatic bone cyst, and idiopathic bone cavity. Solitary bone cysts are not true cysts, they lack an epithelial lining and their etiology is uncertain. Solitary bone cysts are common lesions affecting long bones and less frequently, the jaws, especially the mandible. Lesions usually presents a typical radiographic appearance. The goal of this paper is to report a case of a solitary bone cyst in a 19-yearold female mimicking multiloculer benign neoplasm and review the literature. The lesion was treated by surgical curettage. No additional treatment, such as a surgical reconstruction or bone graft was needed. How to cite this article Fındık Y, Baykul T, Bülte M.
