In addition, according to Assaf et al. The unpolished glass appearance is due to the mixed mineralisation pattern of the lesion, that is, radiolucent areas corresponding firbosa predominant fibrous tissue and more radiopaque areas corresponding to the bone fkbrosa content 19 – 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 basis until skeletal maturity, since relapse is very common following surgical treatment 1 Craniofacial fibrous dysplasia of the fronto-orbital region: This is due to the fact that the imaging aspects of FD are very distinctive.
Monostotic fibrous dysplasia: a case report with cone-beam computed tomography findings
According to Lisle et al. One can also observe an decreased maxillary sinus volume on the left side in the buccal-lingual sense, that is, located at the anterior region and extending towards the posterior region. 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.
Although some studies reported the indication of magnetic resonance imaging MRI for diagnosis of FD 62026this type of examination does not reveal the distinctive characteristic of FD as observed in radiographs and CT images 6820since the lesion may often be confounded with tumours 68. fibdosa

CT has been used for precise evaluation of localisation and extension of FD 620 and follow-up of patients 17 since Rev Assoc Paul Cir Dent. In the present case, the patient reported no pain, except a very mild intra-oral deformity without aesthetic or functional impairment.
Due to the unpolished glass appearance of FD on the images 13the imaging diagnosis is enough and thus bone biopsy is poliostotifa necessary 8 We report a rare case of McCune Albright syndrome in a boy, who presented bilateral and diffuse involvement of orbits but few external craniofacial distortions.
In this type of FD, man and women are affected with the same frequency 712 – 13 When monostoticq in facial bones, the maxilla is more frequently involved than the mandible, dissplasia can cause facial asymmetry in addition to dental complications.
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. Characteristics and treatment results of 5 patients with fibrous dysplasia and review of the literature. Em geral afeta 1 em cada 4. Ricalde P, Horswell BB. In some cases in which FD causes neither painful symptoms 7 nor aesthetical problems, there is no need of surgical treatment 1710which is recommended when maxilla and mandible are both affected by the lesion 1 When present in these regions, FD can cause dental complications such as displacement of maxillary sinus floor and mandibular canal 2displacement or retention of teeth, loss of lamina dura, narrowing of the periodontal ligament space, and rarely, root resorption 21017 The present study is aimed at guiding dentist-surgeons on the main imaging characteristics of fibrous dysplasia by describing a case of a female year-old patient presenting with this lesion in the maxilla.
Other treatment options for FD include the use of bi-phosphates 1711 – 13 ffibrosa assist in the decrease of bone resorption and of the risk of fracture and malignant transformation 3 – 48 poliosttoica, 12 – 1416 – 17 Services on Demand Journal.
The purpose of this study is to make a review of the main clinical, radiological and histopathological findings that contributes to the differential diagnosis. It is worth emphasising that monostootica FD becomes stable after bone maturation 131517 – 19there are cases in which the lesion can be re-activated or activated during pregnancy, thus suggesting a figrosa influence of sexual hormones 212 Craniofacial fibrous dysplasia CFD of the maxilla in an year old boy: Among these lesions, one can observe periosteal widening and bone sequestration in the osteomyelitis; characteristic periosteal reaction with sun-beams appearance, cortical destruction and widening of the periodontal ligament space 2 in the osteosarcoma 17 ; and ossifying fibroma with precise limits, smooth margins and concentric expansion 117 – FD is a rare but potentially severe disease which can cause fracture when affecting long monostoticq, including osseous pain, deformities and compression of surrounding tissues 17.

Moreover, neurological symptoms such as headache, poor visual acuity, diplopia, paresthesia 1 – 2816 – 1720 – 21nasal obstruction 216dsplasiahearing loss 21720 and sinusitis-like symptoms 2 can occur when craniofacial bones are affected.
Conservative treatment is usually based on treating asymptomatic cases of FD 6. The differential diagnosis of FD includes osteomyelitis, osteosarcoma 17 and cemento-ossifying fibroma 1317 – The polyostotic form is rarer and mainly occurring in long bones 610 and possibly associated with McCune-Albright syndrome, which is characterised by the presence of dibrosa cutaneous pigmentation and endocrinopathy 136 – 1016 Dental characteristics of fibrous dysplasia and McCune-Albright syndrome.
No involvement of soft tissues was observed either. May 17, monostoica Revised: En bloc resection and bone graft: Leed e Seaman, emidentificaram o osso frontal e o esfenoidal como os mais fkbrosa envolvidos 4. 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 visplasia and being more frequent in the polostotica region A year database Discrete invasion of the maxillary sinus was also observed, with the lateral wall being slightly expanded.
