Moreover, neurological symptoms such as headache, poor visual acuity, diplopia, paresthesia 1 dsplasia 2816 – 1720 – 21nasal obstruction 21621hearing loss 21720 and sinusitis-like symptoms 2 can occur when craniofacial bones are affected.
fivrosa Cone-beam computed tomography; Fibrous dysplasia monostotic; Maxilla. In the panoramic, axial, coronal and three-dimensional reconstructions Figures 1 to 4 one can observe the image of a heterogeneous, expansive, bone density displasiq irregular contour and unpolished glass appearance involving the alveolar ridge, extending from polioetotica incisor region to the second upper left molar, displacement of teeth 21 and 23, changes in the lamina dura and periodontal ligament, but without root resorption.
Therefore, MRI can be used for evaluation of more complex cases of FD such as patients with compression of neurological structures, involvement of soft tissues and pre-surgery evaluation of vascular structures 6. As the majority of the monostotic lesions are asymptomatic, they are only discovered by means of imaging examinations ordered for other purposes 13 Services on Demand Journal.
Craniofacial fibrous dysplasia CFD of the maxilla in an year old boy: Fibrous dysplasia is a benign, slowly progressive bone disorder, in didplasia normal bone is replaced by fibrous tissue. J Am Acad Orthop Surg. The surgical treatment of fibrous dysplasia. Br J OralMaxillofac Surg.
Em geral afeta 1 em cada 4. In addition, according to Assaf et al. Indications for surgical treatment include the following: In the image exams, the main characteristic of fibrous dysplasia is its unpolished glass appearance. Although its aetiology is unknown, it is thought that FD may be of genetic or traumatic origin monkstotica.
J Med Imaging Radiat Oncol. CBCT has provided important clinical contribution by allowing us to evaluate lesions in detail and the precise involvement of surrounding tissues, including pre-surgical evaluation when necessary and follow-up of the patients. Artigo aceito em 20 de novembro de Discrete invasion of the maxillary fibrowa was also observed, with the lateral wall being slightly expanded.
Displasia fibrosa poliostótica: presentación de un caso
The purpose of this study is to make a review of the main clinical, radiological and histopathological findings that contributes to the differential diagnosis. Artigo recebido em 6 de setembro de This is an open-access article distributed under the terms of the Creative Commons Attribution License.
Am J of Ophthal ; 3: In the present case, one of the teeth affected by the lesion was under orthodontic traction. Characteristics and treatment results of 5 patients with fibrous dysplasia and review of the literature. Craniofacial fibrous dysplasia of the fronto-orbital region: The main differential diagnosis of the monostotic form on head and neck bones is Ossifying Fibroma which some consider another form of the same entity. Collaborators ED COSTA was responsible for bibliographic update, discussion and article writing, review and critical analysis of the content of the article.
Nevertheless, in those cases of mild deformity as in the present caseit is recommended to follow up the lesion by performing imaging examinations on a periodical monostofica until skeletal maturity, since relapse is very common following surgical treatment 1 J Oral Maxillofac Surg.
Rua Casa do Ator, – cj.
One can also note discrete invasion of the left maxillary sinus by the lesion, with the lateral wall being slightly expanded. Simultaneous occurrence of facial fibrous dysplasia and ameloblastoma. FD is a rare but potentially severe disease which can cause fracture when affecting long bones, including osseous pain, deformities and compression of surrounding tissues 17. 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.
Craniofacial FD may also be associated with dental problems, such as malocclusion 491620 – 21changes in tooth positioning and prolonged retention of deciduous teeth 9thus affecting mastication and speech The long term follow up of this pacients is necessary in order to make an early diagnosis of recurrences.

Computed tomography is the ideal method for evaluating this lesion and its relationship with adjacent structures. No involvement of soft tissues was observed either. The unpolished glass appearance is due to the mixed mineralisation pattern of the lesion, that is, radiolucent areas corresponding to predominant fibrous tissue and more radiopaque areas corresponding to the bone tissue content 19 – Juiz de Fora, MG, Brasil. FD is frequently found in children and young adults 617such as in the present case of a female year-old patient.
It is worth emphasising that the initial lesions are more radiolucent, becoming more radiopaque as the lesion develops 16 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 FD reaches the sphenoid, temporal, zygomatic and frontal-nasal bones of the maxilla and skull base is termed as craniofacial FD 1811 – 12 Reversible visual loss caused by fibrous dysplasia. Maxilla and mandible are the most affected bones in the craniofacial region 11with the lesion affecting more commonly the posterior than the anterior regions of the arch 2 and being more frequent in the buccal region CT has been used for precise evaluation of localisation and extension of FD 620 and follow-up of patients 17 since Fibrous dysplasia FD is a rare benign fibro-osseous lesion 1 – 7 characterised by the gradual replacement of the normal bone by fibrous tissue and immature bone 58.
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 present case, the CBCT images showed a dense expansive mass limited to the maxilla, with fibroda of unpolished glass. How to cite this article. This is due to the fact that the imaging aspects of FD are very distinctive.
