Idiopathic Bone Cavity of Mandibular Symphysis: a Case Report

Introduction:An idiopathic bone cavity of the jaw is a rare pseudocyst with unclear etiology and is most commonly found in the body of the mandible. This lesion is generally asymptomatic and incidentally discovered on dental radiographs. Objetives:The aim of this study is to report the case of a 15-year-old male with surgical treatment of this lesion involving the mandibular symphysis, but the vitality pulp was positive. Conclusion: Although there is a non-surgical or surgical option for the treatment of this lesion, the latter is most indicated due to the possibility of a definitive diagnosis and improving bone repair.

RADIOLOGIC PROGNOSIS OF AN IDIOPATHIC BONE CAVITY OF THE MANDIBLE IN 1-YEAR PERIOD

An idiopathic bone cavity (IBC) tends to rise as an abnormality in osseous growth, a degenerating tumoral process, or triggered by hemorrhagic trauma. This paper describes the interpretation of an IBC and its progression over one year. The patient’s initial radiographic images showed well-defined multilocular radiolucency located at the right mandibular molar region, extending between the teeth and the mandibular basis. No clinical symptoms were present, and the course of the mandibular canal was not altered. The lesion was not initially biopsied due to the patient’s dental anxiety. Over one year, the radiolucent area extended anteriorly and thinned the lingual and buccal cortices. Prior radiolucent areas changed to granular-appearing bone. The diagnosis was based on a fine-needle aspiration biopsy. The appearance of an IBC is not unique; its benign nature should be differentiated from multilocular or fibro-osseous lesions by a careful interpretation of clinical and radiological perspectives.

Idiopathic bone cavity: clinical and radiological features of 90 retrospective cases and surgical treatment.

ObjectivesThe purpose of this study was to evaluate the clinical and radiographic characteristics of idiopathic bone cavity (IBC) to determine the effect of surgical intervention on the process of healing.Materials and MethodsAll cases diagnosed with IBC during the period of 2011 to 2020 at our Department of Oral and Maxillofacial Surgery were searched. Ninety cases were retrieved. The features evaluated were sex, age, contour of the lesion, number of teeth involved, site, history of trauma, and postoperative healing pattern. The significance of differences was assessed by Mann–Whitney U test and chi-square test.ResultsThe femalemale ratio showed no predilection toward either sex (0.90.8). The mean age of the collected sample was 22.05±14.38 years, and the age ranged from 10 to 58 years. All cases presented in the mandible and showed well-circumscribed radiolucency. Margins were either scalloped or round in shape, and the size varied from one tooth to six teeth involvement. Seventy cases involved three or fewer roots. Three cases showed bilateral lesion. Four cases had a history of trauma at the area of the lesion. Fifty-one cases were followed for six months after surgery, and all showed increased bone density at the lesion.ConclusionThere is no definitive radiological or clinical feature of IBC. Considering the diversity of clinical and radiological features, such a diagnosis relies primarily on surgical findings of an empty bone cavity with no epithelial lining. Our data suggest that surgical intervention be the first choice of treatment as opposed to observation.

Stafne's idiopathic bone cavity: characteristics and imagenological considerations. A review

In 1942, Dr. Edward Stafne presented 35 cases of asymptomatic, clearly defined, round or ovoid radiolucencies occurring near the angle of the mandible, with a greater incidence below the lower dental canal, between the mandibular angle and the roots of the first lower molar, which he referred to as a bone defect. This bone defect later became known by other names.Clinically, Stafne's idiopathic bone cavity (SIBC) is asymptomatic, is usually not palpated intraorally and has no present extraoral signs. Thus, in most cases it is an accidental radiological finding, which appears as a delimited, elliptical or rounded radiolucent image, with a diameter ranging from 1 to 3 cm, and delimited by osteocondensation in the anteroinferior limits. According to the location of the findings, they are classified as; anterior, posterior and branch.This entity should be considered as a variant of normality requiring differential diagnosis to achieve an accurate diagnosis. The present review provides information on the history, and general and radiographic characteristics of SIBC to facilitate diagnosis when presented with this type of findings.

Cone beam CT - A preferable imaging modality to diagnose stafne’s bone cavity

The Stafne’s bone cavity is a depression of the mandible on the lingual surface. The Stafne defect is normal anatomical variant because of depression created by salivary gland tissue associated with the submandibular gland. Cone Beam Computed Tomography (CBCT) is newer radiological tool for diagnosing maxillofacial diseases and dental implant planning. The Stafne bony cavity is incidental finding in dental radiographs and CBCT. We are reporting five cases of Stafne bone cavity with pictures of CBCT to emphasize the preferable imaging modality for diagnosing Stafne’s bone cavity.

Idiopathic Bone Cavity: Clinicopathologic Features from a Case Series with Emphasis on Differential Diagnosis of Chronic Apical Periodontitis

IntroductionIdiopathic bone cavity (IBC) is an uncommon bone lesion that usually affects youngsters as an unilocular radiolucency with predilection for the posterior mandible. Because the lesion is frequently located in proximity to the adjacent teeth, chronic apical periodontitis is commonly included as a differential diagnosis. The aim of the present study was to analyze the clinical and radiologic features of a series of IBCs diagnosed in a single service. MethodsAll cases diagnosed as IBC were retrieved from the files of an oral pathology laboratory, and the clinical and radiologic characteristics were described with a focus on the differential diagnosis with chronic apical periodontitis. ResultsThirty cases composed the final sample. The mean age of the affected patients was 22 years old; there was no sex predilection, and most lesions were located on the posterior (47%) and anterior (43%) mandible. Most lesions presented as unilocular radiolucencies (87%), and 90% were located in close association with the adjacent teeth. The associated teeth presented no endodontic involvement, and all proved to be vital. ConclusionsIBC usually affects young patients as an unilocular radiolucency in close association with the adjacent teeth. Careful radiologic analysis and vitality tests of the adjacent teeth are essential to rule out chronic apical periodontitis, thus avoiding any unnecessary endodontic treatment.

Cell‐block as ancillary tool for the diagnosis of cystic and cyst‐like jaw lesions

The cell-block technique is a cytological diagnostic method that decreases cellular dispersion; however, its usefulness regarding intraosseous lesions is underexplored. Therefore, this study aimed to assess the diagnostic usefulness of cell-block for cystic and cyst-like jaw lesions. Individuals with cystic or cyst-like jaw lesions who underwent aspiration biopsy were considered eligible. Aspiration of luminal content was prepared and processed by the cell-block technique. Cytological evaluations were blindly performed by two trained PhD students (in a single evaluation) and one oral and maxillofacial pathologist (OMP). Cohen's kappa statistic was used to measure inter-rater agreement. The sample was composed of 52 lesions, represented by 25 radicular cysts (RC), 17 odontogenic keratocysts (OKC), 5 idiopathic bone cavities (IBC), and 5 unicystic ameloblastomas (UA). The kappa coefficient of cell-block compared to histopathological diagnosis was 0.390 (95% confidence interval [95%CI], 0.195-0.585) for PhD students and 0.612 (95%CI, 0.433-0.791) for the OMP. The highest concordance rates between cell-block and histopathological diagnosis were observed for RC (PhD = 76.0%; OMP = 80.0%) and OKC (PhD = 58.8%; OMP = 76.5%). Conflicting results were found regarding IBC (PhD = 40.0%; OMP = 80.0%) and UA, that presented the overall lowest concordance rates (PhD = 20.0%; OMP = 40.0%). The cell-block technique presented a high diagnostic usefulness for detecting RC and OKC and, if associated with clinical and radiographic characteristics, might be sufficient for final diagnosis of these diseases. Regarding IBC and UA, an analysis with a higher number of cases is recommended to determine the true usefulness of the cell-block as ancillary tool for the diagnosis of these lesions.

IDIOPATHIC BONE CAVITY ASSOCIATED WITH OSSEOUS DYSPLASIA: CASE REPORT

A 46-year-old female patient with melanoderma was admitted to the stomatology outpatient clinic with a protruding buccal and lingual cortical bone in the maxillary and mandibular bones. In the physical examination, the mucous membranes remained intact. When palpating, we noticed bone crepitation in the maxilla and mandible bones. The panoramic x-rays showed well-defined radiolucent images without any radiopaque halos extending from the right mandibular ramus to the molar region on the left. In the maxilla, though, the lesions extended to both sides of the molar regions. No root reabsorption was noted. With hypotheses of odontogenic neoplasia, a biopsy was performed in the mandible and maxilla, which revealed hollow cavities devoid of contents. Fragments were submitted for anatomopathologic analysis and showed bone trabeculations of a reactionary aspect. After we assessed both clinical and histopathologic findings, we suggested idiopathic bone cavity associated with fibrous dysplasia. Four-month postprocedure radiograph showed evidence of partial bone neoformation.

A non-pathological lesion - Stafnes bone CYST

Stafne bone cysts (SBC) are asymptomatic bony depressions present on the lingual aspect of mandible caused by soft tissue involvement. As SBC’s are asymptomatic radiolucent lesion on the mandible, they are incidentally seen during a routine radiographic examination. Diagnosis of such lesions is essential due to its radiographical similarities with that of other odontogenic pathologies. We present a case of SBC which was firstly diagnosed with plain radiograph.

Assessment of spontaneous resolution of idiopathic bone cavity.

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.ObjectiveThis study aimed to assess the spontaneous resolution of idiopathic bone cavity untreated by surgery.Material and MethodsTwenty-one patients diagnosed with surgically untreated IBC were submitted to a follow-up protocol modified from Damante, Guerra, and Ferreira 5 (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.ResultsOnly 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”).ConclusionsWe 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.

Simple bone cyst in a 7-year-old child

ABSTRACT The simple bone cyst,or traumatic bone cyst, solitary or idiopathic bone cavity is an intraosseous pseudocyst discovered through a panoramic radiographic examination. Commonly, the SBC is presented as an asymptomatic lesion, radiolucent, unilocular, without cortical expansion, with margins adorning vital tooth roots of the affected region. The literature has recommended that clinical and radiographic aspects of simple bone cyst are quite convincing as to diagnosis, so follow-up through clinical and radiographic examination has been suggested. This case illustrates an exuberant clinical case of simple bone cyst, which was presented as multilocular and expansive lesion in a 7-year-old patient. Surgical exploration was performed because her parents were anxious about the presumptive diagnosis of other more aggressive lesions. The diagnosis of SBC was confirmed. The case was monitored and, after three years, total bone remodeling of the affected area was observed. In conclusion, asymptomatic radiolucent lesions that suggest a strong presumptive diagnosis of a simple bone cyst can be clinically and radiographically monitored. However, clinical variations, as in the present clinical case, require confirmation of the diagnosis, which is performed through exploratory surgery. The establishment of the diagnosis affords the safest approach for both the professional and the patient.

Surgical management of idiopathic bone cavity: case series of consecutive 27 patients.

ObjectivesIdiopathic bone cavity (IBC) is an uncommon intra-osseous cavity of unknown etiology. Clinical features of IBC are not well known and treatment modalities of IBC are controversial. The purpose of this study was to investigate the clinical characteristics of 27 IBC patients who underwent surgical exploration.Materials and MethodsA total of 27 consecutive patients who underwent surgery due to a jaw bone cavity from April 2006 to February 2016 were included in this study. Nine male and 18 female patients were enrolled. Patients were examined retrospectively regarding primary site, history of trauma, graft material, radiographic size of the lesion, presence of interdental scalloping, erosion of the inferior border of the mandible, complications, results of bone graft, and recurrence.ResultsFemale dominance was found. Maxillary lesion was found in one patient, and bilateral posterior mandibular lesions were found in two patients. The other patients showed a single mandibular lesion. The posterior mandible (24 cases) was the most common site of IBC, followed by the anterior mandible (5 cases). Two patients with anterior mandibular lesion reported history of trauma due to car accident, while the others denied any trauma history. Radiographic cystic cavity length over 30 mm was found in 10 patients. Seven patients showed erosion of the mandibular inferior border. The operations performed were surgical exploration, curettage, and bone or collagen graft. One bilateral IBC patient showed recurrence of the lesion during follow-up. Grafted bone was integrated into the native mandibular bone without infection. One patient reported necrosis of the mandibular incisor pulp after operation.ConclusionDifferential diagnosis of IBC is difficult, and IBC is often confused with periapical cyst. Surgical exploration and bone graft are recommended for treating IBC. Endodontic treatment of involved teeth should be evaluated before operation. Bone graft is recommended to reduce the healing period.

A Management Strategy for Idiopathic Bone Cavities of the Jaws

Idiopathic bone cavities (IBCs) are benign osseous pseudocysts of unclear etiology. Their clinical course and response to treatment are poorly understood. The purpose of this study was to present a case series of patients with IBC with long-term follow-up. A retrospective case series of patients with IBC of the jaw was implemented. Medical records were reviewed for data on presentation and imaging. All patients underwent surgical exploration to confirm the diagnosis. Follow-up radiographs were evaluated for resolution or persistence after the procedure. Descriptive data were summarized. The sample included 45 patients (60% girls) with 47 IBCs who presented at a mean age of 13.5 ± 0.35years (range, 9 to 17yr). All lesions were asymptomatic and discovered as incidental findings; the average size was 2.0cm (range, 0.8 to 7cm). Most (n= 44) were solitary lesions of the mandible presenting within the body (n= 27), symphysis (n= 15), or ramus (n= 2). One patient had synchronous bilateral mandibular and maxillary IBCs. Common radiographic features included scalloping without root resorption or displacement and cortical thinning without expansion or perforation. Intraoperative findings showed an empty bone cavity often filled with blood-tinged serous fluid or blood. The histopathology of scrapings from the bony wall showed benign mixed fibrous tissue and no epithelial lining. Average radiographic follow-up was 32.7 ± 6.7months (range, 0 to 9yr). After exploration and curettage, 43% of patients had complete bone fill within 2 to 5years. The other 57% had no change in lesion size at an average of 2.25years (range, 2 to 9yr). No patients developed symptoms, had enlargement of the lesion, or had pathologic fracture. Many IBCs persist for years despite exploration and curettage. Nonetheless, unresolved lesions did not enlarge or cause harm. A single procedure to confirm the diagnosis is sufficient for management.

Does platelet-rich plasma enhance healing in the idiopathic bone cavity? A single-blind randomized clinical trial

The presence of an idiopathic bone cavity (IBC) is usually identified during routine dental radiographic examinations. The purpose of this study was to investigate the effect of platelet-rich plasma (PRP) on bone healing in the idiopathic bone cavity. This was a single-blind randomized clinical trial. Twenty-four subjects were assigned randomly to two groups. Subjects in group 1 received PRP through a buccal window approach, and those in group 2 underwent conventional management via the creation of a window on the buccal wall and curettage of the walls of the defect. Subjects were followed up at 3, 6, and 9 months after the intervention. The amount of bone formation as determined on panoramic radiographs was divided into four categories: stage 1: ≤25% of the defect showed opacity; stage 2: 25–50% of the defect showed opacity; stage 3: 50–75% of the defect showed opacity; and stage 4: >75% of the defect showed opacity. There was a significant difference between the two groups with regard to the various healing stages at the three time points (P<0.05). When compared with conventional management of the idiopathic bone cavity, the use of PRP may enhance bone formation.

Quiste óseo simple de cóndilo mandibular

Simple bonecysts (SBC) have been a recognized entity since 1929, when they were first described by Lucas. In 1946, Rushton described the inner walls of the cyst, consisting of bone and no pathological or chemical content. This intraosseous entity, is also known by a variety of synonyms including solitary bone cyst, traumatic bone cyst, hemorrhagic bone cyst, unicameral cyst, idiopathic bone cavity and progressive bone cyst or cavity. There are few clinical features within the jaws, and the diagnosis is made mainly from radiographical findings. The most frequently affected sites are the region between inferior canines and third molars, and secondly in the mandibular symphysis. SBC of the condyle are rare, and there are approximately 15 cases in the current literature.Treatment of the case will be described, and a literature review of the disease and its management will be presented.

Retrospective study on idiopathic bone cavity and its association with cementoosseous dysplasia

The goal of this study was to reveal clinical and pathologic findings on idiopathic bone cavity lesions (IBC). A retrospective analysis of 20 IBC cases diagnosed from 2004 to 2014 from a university-based maxillofacial pathology service was performed and included all pertinent clinical, histologic, and radiographic findings. Eleven women (age = 36 ± 12.7) and 9 men (age = 23 ± 17.9) diagnosed with IBC were selected for analysis. There was a higher African-American female predilection (40%). Thirty percent of the cases were associated with florid cementoosseous dysplasia (COD) (all middle-aged African-American women). The location of the lesions was mandibular in 85% of the patients. All symptomatic patients (25%) had concomitant COD. Only 1 patient reported previous trauma, and only 1 patient had prior orthodontic treatment. Follow-up period ranged from 1 to 8 years, with only 1 recurrence 3 years after surgery. The results suggest that IBC concurrent with COD may not be as rare as the literature implies. Clinicians must be attentive to this possible relationship to ensure accurate diagnosis and appropriate treatment.

Huge Solitary Bone Cyst located in Posterior Mandible

ABSTRACT 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.

Multiple Mandibular Idiopathic Bone Cavities in a Patient with Immune Thrombocytopenia : A Case Report

The immune thrombocytopenia(ITP) is defined as a platelet count of less than 100,000/µL. It is gene rally known as characterized by the bleeding manifestations of skin and/or mucosa like ecchymosis due to low platelet count, but reports of the related intraosseous lesions are not common. The idiopathic bone cavity(IBC) is an empty space of the bone, which occurs mainly in the long bones. It is found predominantly in the mandible in case of the maxillofacial area. In general, it appears as an isolated unilocular lesion without the correlation of the teeth. Although the cause of the IBC is supposed to be associated with hemostatic problems, the etiology is unclear and it was not disclosed the relevance of specific systemic disease. In this present case, IBCs that occurred in mandible of patient who has IPT was treated by curettage with platelet transfusion.

Unilocular radiolucencies of anterior mandible in young patients: A 10 year retrospective study

Introduction:Mandibular anterior region is an uncommon site for occurrence of intrabony pathologies. Unilocular presentation of a lesion is again less common than multilocular appearance. Demographically, most lesions occur in middle to elderly age group. The study is designed to review the pathologies manifesting a combination of these rare demographic and radiological criteria.Materials and Methods:A retrospective analysis of patients with anterior unilocular radiolucencies of mandible in young patients was done. Records of past 10 years were searched. There were a total of 17 patients. Their clinical history and radiographs were reviewed from the case files and correlated with histopathological examination of the lesion.Results:Nine different pathologies constituted the sample size of 17. A wide array of lesions was found to manifest similar signs and symptoms and radiographic findings namely ameloblastoma (three), adenomatoid odontogenic tumor (AOT, four), odontogenic keratocyst (OKC, three), ossifying fibroma (OF, two), idiopathic bone cavity (IBC, one), dentigerous cyst (DC, one), radicular cyst (RC, one), central giant cell granuloma (CGCG, one), and calcifying odontogenic cyst (COC, one).Conclusion:Anterior mandible is a rare site for occurrence of intrabony pathologies. Majority of patients are females. Lesions acquire large size before they are detected. Growth occurs more in length than in width. Root resorption is not uncommon and root displacement is almost a consistent feature.
