Abstract Introduction: Fibrous dysplasia is a benign bone lesion characterized by replacement of normal bone by fibrous connective tissue, and its diagnosis is based on clinical, radiological and histological findings. Objective: The aim of this study was to report a case of unilateral fibrous dysplasia in the maxilla, in the palate region, by using computed tomography. Results: On examination it was observed: a nodular lesion, with similar staining to the palatal mucosa with varicosities, regular edges, irm and painless. The radiographic indings on computed tomography showed one diffuse and heterogeneous thickening of the bony elements involving the hard palate extending to the posterior wall of the maxillary antrum. We opted for the preservation of the case, considering the age of the patient, the absence of facial asymmetry and lack of aesthetic and functional impairment. Conclusion: Thus, we emphasize that the knowledge of morphological changes is important for the diagnosis of bone pathologies, and the dentist must be familiar with the normal morphology of the structures and their possible abnormalities.

ABSTRACT Coronoid Process Hyperplasia is a rare condition characterized by the increase in size of a histologically normal bone. It can be confused with Temporomandibular Joint Dysfunction, due to the presence of major signs/symptoms, including the limitation of mouth opening, pain, and facial asymmetry. Although several theories have been proposed, the etiology remains unknown. The recommended treatment is mandibular coronoidectomy. In the present study, the importance of computed tomography to reach the proper diagnosis and the surgical treatment plan is demonstrated.

ABSTRACT Introduction: Facial asymmetry associated with unilateral condylar hyperplasia (UCH) is a complicated clinical condition. Objective: The objective of this study was to describe morphological characteristics of the mandible and the temporomandibular joint in patients with facial asymmetry, using computed tomography and 3D reconstruction. Methods: A retrospective observational study was performed with patients displaying facial asymmetry evaluated by single photon emission computed tomography (SPECT)/CT analysis, for suspected UCH, between 2015 and 2018. The following variables were compared between the affected side (producing the asymmetry) and the contralateral side (side to where the jaw is deflected): condylar length, condylar medial and lateral pole length, mandibular ramus length, intra-articular spaces, articular eminence height and position of the posterior wall of the glenoid fossa. Results: Forty-three patients (21 women, mean age: 20.7 ± 7.25 years) with facial asymmetry were included, 19 patients presented right side deviation and 24 patients had left side deviation. Condylar length, lateral pole length, the sum of maximum values and articular eminence height were greater in the affected side (p< 0.05). A positive correlation was found between the position of the posterior wall of the glenoid fossa and the articular eminence height in the affected side (r = 0.442). Conclusions: In patients with suspected UCH, evaluated through CT, craniofacial measurements showed significantly larger condylar length and the condylar sum of maximum values in the affected side. A positive correlation was found between the increased dimensions of the articular eminence and the more posterior position of the glenoid fossa in the affected side.

AbstractFibrous dysplasia is a slowly progressive bony disorder where normal bone is replaced by abnormal fibroosseous tissue. Its monostotic variety in the temporal bone is very rare and such a case is presented here. Computed tomography (CT) may be adequate for the diagnosis and follow-up of these patients. Limited surgery should only be considered in cases of symptomatic disease.

Introduction:Fibrous dysplasia (FD) is a fibroosseous lesion of the osseous structures of the body. It is not a commonly reported lesion yet it is considered as an important lesion which can affect the maxillofacial region as well. As a result, it can cause deformity of the jaw bones which can further lead to severe facial asymmetry. Craniofacial fibrous dysplasia (CFD) is one of the subtypes of FD that can affect the bones of the craniofacial complex, including the mandible and maxilla. It can also present as facial asymmetry and can be investigated with the help of Maxillofacial Radiology and Imaging. The radiographic findings may vary according to the extent and degree of the disease. Although conventional radiographs provide a good clue regarding the lesion, advanced maxillofacial imaging is capable of providing detailed extent of the disease. Furthermore the classification of CFD is not very clear in the literature.Case Report:This particular paper attempts to document and report the CT appearance of CFD with an attempt to propose a better classification system for the same. Four different patients are reported which presented with FD with involvement of bones of craniofacial region. Working diagnosis of CFD was made with the help of clinical features as well as with radiographic assessment. Advanced imaging included CT scan of the lesions. The article highlights the importance of computed tomography in diagnosis as well as assessment of extent of the disease.Conclusion:It can be concluded that the Dental professionals must be aware regarding the different radiographic appearances of CFD. Advanced imaging modality like CT can provide with exact diagnosis as well as extent of the lesions like FD. Further collaboration of researchers is required to incorporate this proposed change in classification of CFD.

ABSTRACT Fibrous dysplasia is a benign fibrous-osseous lesion in which normal bone is replaced by fibrous connective tissue and immature bone, affecting only one (monostotic) or several bones (polyostotic) and mainly occurring in children and young adults. When present in facial bones, the maxilla is more frequently involved than the mandible, which can cause facial asymmetry in addition to dental complications. In the image exams, the main characteristic of fibrous dysplasia is its unpolished glass appearance. Computed tomography is the ideal method for evaluating this lesion and its relationship with adjacent structures. The use of conventional radiography, due to the overlapping of anatomical structures, makes it difficult to delineate the extension of the lesion. The present study is aimed at guiding dentist-surgeons on the main imaging characteristics of fibrous dysplasia by describing a case of a female 10-year-old patient presenting with this lesion in the maxilla.

Introduction: fibrous dysplasia of bones is a non-hereditary congenital benign bone disorder, where normal bone is replaced by pseudofibrous tissue containing immature osteogenesis.Case report: a 29-year-old patient with chronic hemodialysis who had a swollen mouth and hard palate that had been evolving for a year, impeding chewing and swallowing and causing facial asymmetry. Cranio-facial CT revealed multiple osteolytic bone-blast lesions, the histopathological study of which favored polyostotic fibrous dysplasia.Discussion: fibrous dysplasia lesions may be single or multiple and may be responsible for pain and fragility, causing neurological complications in craniofacial localization. Imaging and, when a biopsy is needed, histology can establish the diagnosis. The treatment is based on bisphosphonates or, in special cases, surgical excision.

ABSTRACT Objective: To compare the condylar displacement following sagittal split ramus osteotomy (SSRO) in asymmetric setback patients between the conventional approach and surgery-first approach and to determine whether the condylar displacement is affected by asymmetric setback in SSRO patients. Materials and Methods: This was a retrospective study. The subjects consisted of patients with facial asymmetry who underwent SSRO and had cone-beam computed tomography taken before and 1 month after surgery. They were allocated into the conventional (n = 18) and surgery-first (SF) groups (n = 20). Descriptive, independent t-tests and Pearson correlation analysis were computed. Results: The amount of condylar displacement in x-, y-, and z-directions and Euclidean distance showed no statistically significant differences between the conventional and SF groups. Comparing the postoperative condylar position with the preoperative position, the condylar displacement occurred in posterior (P &lt; .05) and downward (P &lt; .05) directions in both groups except on the deviated side in the conventional group. The condylar displacement occurred in a posterior (P &lt; .05) direction on the deviated side of the conventional group. However, the condylar displacement in three dimensions showed no statistically significant differences between the two groups. In the correlation analysis, the condylar displacement in both the deviated and contralateral sides showed no significant correlation with asymmetric setback in either group. Conclusion: The condylar displacement in three dimensions and the distance of condylar displacement in SSRO patients with facial asymmetry showed no significant difference between conventional and SF groups. Condylar displacement was not associated with asymmetric setback.
