1/13. Progressive unilateral mandibular swelling in adolescence: a diagnostic dilemma.Asymmetrical swelling of the mandible in adolescence may pose a significant diagnostic dilemma. The differential diagnosis ranges from traumatic, infectious, and metabolic processes to benign and malignant tumors. Among them, fibrous dysplasia, osteomyelitis, and malignancy may present with similar clinical and radiological features, making an accurate diagnosis quite difficult. This is an illustrative case involving a 14-year-old girl who initially presented with diffuse fibrous dysplasia of the mandible and in whom a superimposed osteomyelitis of the left side subsequently developed. Multiple investigations and several biopsies were required to arrive at a diagnosis. Similarities in clinical and radiographic findings of fibrous dysplasia, osteomyelitis, and malignancy are presented, and implications for treatment are discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/13. Cystic degeneration in fibrous dysplasia of the jaws: a case report.A case of nonspecific cystic degeneration complicating fibrous dysplasia of the mandible is presented. This condition is extremely rare in the jaw bones. The patient had a painless swelling of the right face measuring 10 cm in diameter, and there was no history of trauma. Radiographs showed a poorly defined, "ground glass" radiopaque lesion; a central well-defined cyst was confirmed by means of computed tomography. During surgery, a large cystic cavity with surrounding, soft fibrous bone that merged with the cortex was observed. Histologic examination showed a large non-epithelial-lined cystic cavity with a surrounding fibro-osseous lesion, which was consistent with a diagnosis of fibrous dysplasia.- - - - - - - - - - ranking = 0.91512441229206keywords = mandible, jaw (Clic here for more details about this article) |
3/13. Monostotic fibrous dysplasia of the sphenoid sinus: a serendipitous finding on a bone scan.A 22-year-old woman had a Tc-99m MDP whole-body scan for low back pain. A focal area of increased activity was seen in the skull base in the region of the sella turcica. A computed tomographic examination showed ground-glass opacification of the sphenoid sinus and bony sclerosis along its walls, characteristic of fibrous dysplasia. Monostotic fibrous dysplasia, the more common form compared with the polyostotic variety, occurs in 70% to 80% of all patients with fibrous dysplasia. Monostotic lesions usually involve the ribs, femur, tibia, cranium, maxilla, and mandible. The frontal and sphenoid bones are the cranial bones most commonly involved.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
4/13. Treatment of fibrous dysplasia of the mandible with radical excision and immediate reconstruction: case report.Monostotic fibrous dysplasia of the mandible is an unusual manifestation of the disease that is usually benign, occurs in young individuals, and is managed by conservative curettage or debridement. We present a case of persistent fibrous dysplasia complicated by pain and intraoral bony exposure that was successfully managed by radical resection and reconstruction with a free fibular flap. Although mandibular fibrous dysplasia is preferentially managed conservatively, treatment of this disease has evolved to a point where total excision and immediate reconstruction may be the treatment of choice and offer the best outcome.- - - - - - - - - - ranking = 2.5keywords = mandible (Clic here for more details about this article) |
5/13. Prosthodontic treatment for patients with large mandibular defects; porous hydroxyapatite grafts.It is difficult for both prosthodontists and their patients with large marginal defects to achieve a satisfactory prosthodontic result, because retention, support, and stability of the prosthesis are limited and recovery of esthetics is unsatisfactory owing to large mandibular defects. alveolar ridge augmentation therapy is performed to compensate for such problems. We have experienced a good prognosis of prosthodontic treatment for over 10 years in two patients with large marginal defects of the partially edentulous mandible, who had undergone grafting of porous hydroxyapatite blocks to their bone defects. It has been reported that porous hydroxyapatite blocks are unsuitable for edentulous patients, because the mucosa covering the hydroxyapatite block is too thin and delicate to support dentures. We, therefore, designed the denture to prevent concentration of occlusal stress on the mucosa. In both of these two cases, we achieved recovery of occlusal function and esthetics by affixing denture to the large marginally resected defect augmented with a graft of porous hydroxyapatite block.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
6/13. Focal cemento-osseous dysplasia involving a mandibular lateral incisor.AIM: To report a case of focal cemento-osseous dysplasia (FCOD) affecting a single tooth misdiagnosed as an inflammatory periapical lesion.SUMMARY: The patient, a black 47-year-old woman complained of pain affecting the right side of the mandible. Routine X-ray examination discovered a periapical radiolucency on the mandibular left lateral incisor (tooth 32), which was otherwise normal and not carious. As the response of this tooth to a vitality test was doubtful, the lesion was diagnosed as a periapical granuloma or cyst secondary to pulpal necrosis. Endodontic treatment and curettage of the periapical lesion were performed, and histological examination of the curettage material revealed a localized osseous dysplasia. KEY learning POINTS: FCOD may rarely affect only one tooth, resembling a periapical granuloma or cyst. Careful diagnosis is of paramount importance in cases of questionable periapical lesions affecting normal-looking teeth, before beginning treatment. FCOD generally requires no treatment. biopsy is warranted in case of doubt.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
7/13. Clinical and radiographic features of chronic monostotic fibrous dysplasia of the mandible.Chronic untreated fibrous dysplasia of the mandible in a 40-year-old man is described, with emphasis on the radiographic findings. To the authors' knowledge, this is the first such case to be reported in the literature. Within this mature mandibular lesion, a large radiolucency was noticed, with the appearance of a simple bone cyst. The patient did not have any symptoms directly related to the mandibular lesion. Various aspects of the diagnosis, radiographic appearance and differential diagnosis are discussed. The information presented here will be useful for all dentists, oral and maxillofacial surgeons, physicians and other health care providers in identifying the appearance of chronic fibro-osseous lesions.- - - - - - - - - - ranking = 2.5keywords = mandible (Clic here for more details about this article) |
8/13. Infantile fibrous dysplasia of the mandible.Fibrous dysplasia of the craniofacial skeleton is an uncommon benign neoplasm. Its appearance in infancy (<1 year) is extremely rare. The authors report a case of mandibular fibrous dysplasia presenting in a patient 12 weeks of age as a painless, primarily left-sided, enlarging neoplasm of bone. Surgical contouring was successfully performed when the patient was 9 months of age. The authors anticipate recurrence, but at 6 months of follow-up no new growth has been observed.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
9/13. Endoscopic surgery for fibrous dysplasia of the sinonasal tract in pediatric patients.Fibrous dysplasia (FD) is a non-neoplastic, expansile lesion of unknown origin. In about one-fourth of cases this disorder affects the head and neck area, where the mandible and maxilla are the most frequently involved sites. Its localization to the ethmoid is a rare event. Since the disease slowly progresses, its management is delayed until significant clinical symptoms or non-well-tolerated aesthetic deformities are present. When required, surgery is the treatment of choice. Several external procedures have been used to manage the lesion, but recently, more conservative transnasal approaches have been proposed. We report the history of a 6-year-old boy with fibrous dysplasia of the ethmoid labyrinth that underwent successful transnasal endoscopic removal. Furthermore, an analysis of the literature is presented with particular emphasis on clinical picture, diagnosis, and treatment of this rare illness.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
10/13. Central giant cell granuloma and fibrous dysplasia occurring in the same jaw.Fibrous dysplasia (FD) is a developmental tumor like condition that is characterized by replacement of normal bone by an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Central giant cell granuloma (CGCG) is described as a benign lesion affecting the mandible and maxilla that consists of a massive fibrohistiocytic proliferation with numerous heavily hemosiderin-laden multinucleate-giant cells. A 20 year old woman present at the Department of oral medicine, dentistry School, Tehran University of Medical Sciences with a slowly growing non painful swelling of the right mandible for one year. Our differential diagnosis was osteoma, osteoid osteoma and Fd. The histological feature reveal Central giant cell granuloma fibrous dysplasia. Central giant cell granuloma and fibrous dysplasia occurring in the same jaw is rarely reported in the literatures.- - - - - - - - - - ranking = 1.4151244122921keywords = mandible, jaw (Clic here for more details about this article) |
