[Osteotomy of the external cortex of the gonial angle in the correction of mandibular asymmetry].

BACKGROUND AND AIM: Patients with facial asymmetries undergoing maxillo-mandibular surgery may have residual asymmetries in the gonial region, body and blade of the mandible that call for further surgery. Other patients may present asymmetries of the lower third of the face that are not associated with occlusal alterations, for which there are no indications for maximally osteotomy. In these cases the authors propose using osteotomy of the outer mandibular cortex to resolve the aesthetic defect. METHODS: A retrospective study was made using a clinical and radiographical evaluation of 7 patients undergoing this operation. The follow-up ranged between 3 and 16 months. The study was performed in 4 patients with residual asymmetry after mono or bimaxillary surgery for facial asymmetry and 3 patients with mandibular asymmetry not associated with occlusal alterations. Surgery included the realisation of osteotomy of the outer cortex of the mandibular angle, with repositioning according to set values and synthesis through rigid fixation. The increased gonial diameter, the degree of reabsorption and the cosmetic results were evaluated. RESULTS: Surgery succeeded in recreating a satisfactory facial symmetry without resorting to extraoral incisions, without using alloplastic materials and minimising the harvesting of autologous material. CONCLUSIONS: The proposed technique enabled the asymmetry to be corrected by maintaining the natural marginal morphology, eliminating the risks of infection, extrusion or deplacement that may occur when using alloplastic materials.

[A case of soft tissue alveolar sarcoma localized in the tongue].

Alveolar soft-part sarcoma is a rare form of malignant tumour. It is generally localized at the limb muscles, rarely in the head and neck. Its histogenesis is still uncertain but its specific cellular characters make the diagnosis easier. The case of a woman with an ASPS of the tongue is described. The morphological aspects and the immunohistochemical results seem, according to the data reported in literature, suitable with the diagnosis of alveolar soft-part sarcoma; however, it is difficult to explain the presence of local positivity to specific neuronal enolase.

[Cerebral hemorrhage: initial experiences with magnetic resonance imaging].

The authors employed MR imaging to examine 29 hematomas (21 spontaneous, 1 traumatic, 2 vascular malformative, and 5 intratumoral). All images were acquired with a 1.5 T superconducting magnet (Signa, General Electric). The different features hemorrhagic collections may present with on MR images and their temporal evolution depend on their dimension, on the different water content of the hematoma and adjacent tissues, on the peripheral macrophage border, and, above all, on the presence of hemoglobin breakdown products, some of which are paramagnetic. The latter is the most important feature as to the nature of the lesion and allows hematomas to be classified as: 1) Acute (1-7 days): presence of intracellular deoxyhemoglobin. 2) Subacute (8-30 days): 2A, intracellular methemoglobin; 2B, intra- and extracellular methemoglobin; 2C, totally extracellular methemoglobin. 3) Chronic (from 30 days on): thick macrophages hemosiderin rim with/without fluid methemoglobin content. The interpretative difficulties initially met caused the authors to arrange schemes, based on the literature data on the subject, to be used as an useful interpretative tool in most of the cases observed.

[Ossification of the posterior longitudinal ligament].

Two asymptomatic, unusually young male patients aged 18 and 21 with ossification of the longitudinal posterior ligament of the cervical spine are presented. Geographical distribution, pathological and radiologic aspects of the disease are discussed together with those signs differentiating it from ankylosing spinal hyperostosis.
