Eosinophilic granuloma of mandible: Report of a case with a 7-year follow-up

Abstract We have presented a case of eosinophilic granuloma of bone in the region of the angle of mandible which was diagnosed through biopsy and successfully treated with radiotherapy. There was no recurrence after 7 years.

Monostotic fibrous dysplasia: a 23-year follow-up of a patient with spontaneous bone remodeling.

Fibrous dysplasia is a benign fibro-osseous disease that affects one or more bones. Although its etiology has been defined, the mechanism of spontaneous resolution is still unclear. There is strong evidence indicating the occurrence of stabilization when bone maturation is completed. Deformities that lead to esthetic and functional disorders are observed in almost all cases. Plastic surgery is often recommended when the maxilla and mandible are involved. In the case of mild deformities, careful follow-up during skeletal growth is recommended. We describe here the 23-year follow-up of a patient with monostotic fibrous dysplasia whose disease had stabilized by 13 years of follow-up.

Estudo radiográfico digital indireto do efeito da expansão de maxila cirurgicamente assistida (EMCA) sobre o septo nasal

INTRODUCTION: Maxillary transversal deficiency is characterized by constricted maxillary arch, dental crowding and rotation, along with posterior uni or bilateral crossbite. The treatment of this deficiency is based on the widening of maxillary bone. In skeletal mature patients the maxillary expansion is achieved by means of surgical-orthodontic procedures (known as surgically assisted maxillary expansion - SAME) that can cause some effects on the nasal cavity and septum. AIM: To evaluate the behavior of the nasal septum after the procedures of SAME. METHODS: Post-anterior cephalometric and maxillary occlusal radiographs, taken by conventional technique and therefore digitalized, were analyzed from 16 patients undergone SAME. For all patients, the SAME technique consisted of subtotal Le Fort I osteotomy. The radiographs were taken before the surgical procedure, right after (mediate post-operatory time) or after the expansion, and thereafter digitalized and measured using DIGORA program. Also, the distances between teeth (canines, first premolars, second premolars, first molars and second molars) were registered. RESULTS: The statistical treatment showed an increase in interdental and intermaxillary distances, along with an increase in the width of the base of piriform aperture and in the distances between the base of lateral wall of the piriform aperture and nasal septum. CONCLUSION: SAME is an efficient procedure that seems not to influence the septum position.
