A case of a patient with a vast craniofacial defect after shooting is reported. The case is of interest because of a large size of the defect. The technique is described how to rehabilitate the patient with reconstruction the face contour and calvarium by silicone implants.
One of the most wide-spread virus infections causing various diseases of dermal integuments, central and peripheric nervous system, viscera, eye, oral cavity and genitalia is Herpes simplex (HS). The clinical case of a 10-year child who had at early age HS infection complicated by extensive cicatrical deformation of frontal-temporoparietal skin is reported. The cicatrical deformation has caused disfunction of periorbital tissues. Principles of treatment are considered and practical references are given.
It is known that the septum of the nose participates in sagittal growth of medial face. Teratogenic deficiency of vitamin K promotes premature ossification of the septum cartilage. It results in hypoplasia of maxillonasal complex, development of characteristic concave profile with the impressed and short nose with half the moon naries, infringement of an occlusion. The orthodontic treatment should be carried out from younger children's age. The surgical treatment is directed on elimination of bone-skeletal infringements of an occlusion, reconstruction of normal contours of middle face and lengthening of a nose. In our clinic for the last 13 years 11 patients with Binder's syndrome were examined and operated.
On the basis of multiple clinical observations (64 persons), classification of the defects in progressive facial hemiatrophy is proposed. Three degrees of atrophy of the facial tissues have been pointed out and the methods of surgical treatment depending on them have been described. In degree I-II atrophy, contour plasty using silicone implants and injections of elastosil are preferred. In degree III atrophy, autotransplantation of free skin-muscle and skin-fascia flaps is performed.

The authors have developed a new working classification of residual defects of the maxillary alveolar process, anterior segment of the hard palate and oronasal anastomosis, based on the results of cheilo- and uranoplasty in 125 patients. The choice of present-day methods of surgery is based on the suggested working classification scheme. The known methods of surgical management of the residual defects are described and new methods developed by the authors suggested, permitting an effective shortening of the terms of surgical rehabilitation and yielding stable functional and aesthetic results.
The authors present the results of laboratory and clinical analysis of vinyl siloxane polymer-based compositions, Pt catalyzer-hardened. Animal experiments have demonstrated high biologic inertness of the implantation material, inducing virtually no irritation of the adjacent tissues. These results confirm the possibility of clinical use of this new material.
