[The determination of the level of the external osteotomy line in Le Fort I interventions for pure maxillary advancement].

Background: Therapy of severe malocclusions needs a cooperation between orthodontist and maxillo-facial surgeon. The aim of this study is to evaluate how the ortho-surgical team can get a common base of programmation to transfer on split-casts osteotomic simulation reaching a more exact surgical result.

Methods: In this paper were considered patients operated by orthognathic surgery from January 1994 to June 1997 have been studied.

[Evaluation of the posture of patients before and after orthodontic surgery].

Introduction And Aims: The term "craniomandibular disorder" is used to describe a series of symptoms and signs that directly affect the stomatognathic apparatus with possible repercussions on the otovestibular and oculomotor apparatus and on the cervical spine that may condition the entire body posture. The aim of this study was to evaluate a series of parameters correlated to the occlusal situation and to verify how these factors are affected by a change following the correction of occulusal ratios.

Methods: The paper reports a series of 15 patients suffering from facial dysmorphia treated surgically in the Division of Maxillofacial Surgery of S.

[Evaluation of tegumental changes after skeletal repositioning in orthodontic surgery].

One of the main problems of orthognathodontic surgery is to evaluate the effects on soft tissue of bone positioning performed following surgical programming. A method which is of particular interest, easy to perform and reproduce was proposed by Jensen in 1992. It evaluates the correspondence of soft tissues on the basis of surgical programming and allows percentage values of soft tissue movement to be calculated in relation to bone tissue, thus performing a surgical VTO which corresponds as closely as possible to the postoperative result.

[Adenophlegmons of the neck area. A case report and review of the literature].

Adenopathies in general and cervicofacial adenopathies in particular are a pathology that can affect both medical and surgical disciplines. They may be found in both acute and chronic disorders, in children and in adults, and in local or systemic forms with benign or malignant pathogenesis. It is clear that the differential diagnosis and consequently the therapeutic approach may be complicated at times by the variety of pathological processes.

[Dermoid cysts of the oral floor. A clinical case report and review of the literature].

The authors report two cases of dermoid cysts of the oral floor. The incidence of this pathology in this region is difficult to assess due to the rarity of reported cases. In particular, dermoid cysts appear to derive from the inclusion of epithelial cells on the median line in the fusion point between the first and second branchial arch.
