[Computer technologies in diagnostics and treatment of worsening post-enucleation socket syndrome]. / Komp'iuternye tekhnologii v diagnostike i lechenii progressiruiushchego anoftal'micheskogo sindroma.

Enucleation with primary orbital implantation and the use of ocular prosthesis does not exclude the risk of post-enucleation socket syndrome (PESS). Correction of such conditions requires modern visualization methods and software for calculation, modelling and control of the surgery. PURPOSE: To demonstrate the capabilities of modern computer technologies in diagnostics and treatment of patients with worsening post-enucleation enophthalmos. MATERIAL AND METHODS: The retrospective study included 6 patients (4 male and 2 female) aged 29-68 years who exhibited signs of PESS in 2017-2018. To define the orbital condition, patients underwent multispiral computed tomography (MSCT) and magnetic resonance imaging (MRI) followed by image analysis with computed exophthalmometry and step-by-step computed exophthalmometry. Results of these examinations helped construct 3D-models of patients' orbits, which were then used to calculate the parameters of the silicone implants. Patient-specific silicone implants were implanted into their orbits during surgery under general anesthesia. RESULTS: Implantation of the patient-specific silicone implant resulted in increase of the volume behind orbital prosthesis and correction of post-enucleation enophthalmos in all patients allowing them to use thinner, more mobile ocular prosthesis, and restore normal eyelid position. The patients also noted better appearance of the eye and personal comfort. CONCLUSION: Modern visualization methods along with computer analysis and modelling, as well as technologies to produce medical products enable creation of the best suitable patient-specific orbital implants. This allows achieving better clinical results and better quality of life for patients with monolateral anophthalmos.

Functional disorders in patients with lip and nose deformity after cheilorhinoplasty. / Funktsional'nye narusheniya u patsientov s deformatsiei guby i nosa posle odnostoronnei kheilorinoplastiki.

Clinical analysis of the nasolabial complex in patients suffering of the unilateral cleft lip and palate deformity after cheilorhinoplasty is presented in the article. Functional disorders such as nasal breathe impairment and it's relation to the nasolabial muscle dystonia in the dependency of primary cheilorhinoplasty type are analyzed. The plan of surgical treatment as well as the postoperative rehabilitation using the botulotoxin injections is offered.

[Nasal breath recovery and rhinoplasty in cleft lip and palate patient with unilateral choanal atresia].

The paper presents the analysis of clinical case of endoscopic nasal breath restoration and elimination of the secondary cleft lip nasal deformity in 27 years old patient with unilateral choanal atresia and secondary nasal deformity after rhinocheiloplasty. Preoperative examination revealed the absence of nasal breathing on collateral side due to complete bone choanal atresia. Surgical treatment included endoscopic choanal repair, elimination of the secondary nasal deformity, septoplasty, conchotomy and lateroposition of the inferior conchae. The treatment resulted in nasal breath restoration and elimination of nasal deformity. Long-term follow-up at 1 and 12 months post-operatively proved stable positive aesthetic and functional results.

[New way of elimination of total and subtotal defects of auricle].

Today the most often used method - many stage otoplasty method with the use of auto- and allocartilage, the basic positions of which were formulated in 60-70 years. The use of temporoparietal arterialized fascial flap let to improve considerably aesthetic results of the operations and shorten the terms of treatment. Suggested way of elimination of auricle defect differs in that that as framework we use silicone implant repeating the form and relief of auricle and temporoparietal fascial flap is cut out according to the auricle form with the correlation of temporoparietal fascial flap and silicone implant as 1.5-2.5:1; the temporoparietal fascial flap is formed in such a way that its upper-back part covers the front and back implant surfaces. The use of silicone implant as auricle framework (due to its elasticity, strength, inertness and biocompatibility) promotes the achieved result preservation and allow patient to sleep on the side of the formed auricle, its blood supply is not affected.

[Spiral computer tomography use on the treatment stages of patients with defects and deformations of face bones and soft tissues].

There are discussed possibilities of spiral computer tomography use in cases of defects and deformations of face bones and soft tissues elimination.

[Correction of a vast craniofacial defect -- a case report].

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.

Surgical treatment of progressive facial hemiatrophy.

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.

[Cicatricial deformation of the face after herpes simplex infection]. / Rubtsobaia deformatsiia litsa posle perenesennogo Herpes simplex.

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.

[The clinical picture and surgical treatment of the residual defects and deformities of the maxillary alveolar process after cheilo- and uranoplasty]. / Klinika i khirurgiucheskoe lechenie ostatochnykh defektov i deformatsii al'veoliarnogo otrostka verkhnei cheliusti posle kheilo- i uranoplastiki.

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.

[Maxillonasal dysostosis: Binder's syndrome]. / Verkhnecheliustno-nosovoi dizostoz--sindrom Bindera.

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.

[A new siloxane material for eliminating defects of the soft facial tissues by an injection method. I. The laboratory and experimental research]. / Novaia siloksanovaia kompozitsiia dlia ustraneniia defektov miagkikh tkanei litsa in''ektsionnym metodom. I. Laboratorno-éksperimental'noe issledovanie.

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.
