Mandibular primary osteoplasty using orthotopic allografts.

This article is based on our results of 30-years experience in primary mandibular reconstruction using orthotopic allografts in 680 patients. Good and satisfactory outcome was achieved in 573 cases and unsatisfactory outcome in 62 (9.8%). Analysis of our clinical material shows that lyophilized and formalinized orthotopic allografts are an optimal material to correct mandibular defects of various size, sites and character. They facilitate formation of organotypical regenerated bone tissue in the place of the allograft and allow achievement of mandibular continuity and good functional and aesthetic results.

[Destructive and reparative processes after UHF and cryo-effect on bone regeneration in dogs].

The experiment was carried out on the lower jaw of mongrel dogs. It included 36 observations on the basis of the morphological method. The aim is to study the effectiveness of the effect of cold and the combination of the UHF radiation on the proliferative reaction of cells of the lower jaw. It was proved that under the influence of cold the skeletogenic tissue undergoes changes. The combination of cold with UHF radiation cause less destructive cold effects on the bone tissue away from the injury of resorption. Hence the effect of cold on the proliferating tissue causing its necrosis proves the possibility of its use in removal of tumours, substituting wide caving around them by more protective intervention: the combination of carving of tumour with the cryodestruction of tissue around it. In such a combination the reparative processes become more effective, which enables us to recommend them for clinical use for curing benign tumour.

[Experience in using moradol in osteoplastic operations in oral surgery].

Osteoplastic operations on the jaws were carried out in 19 patients aged 14-64 under moradol anesthesia. The mean length of the operation was 3 hours. The authors come to a conclusion that moradol in a dose of 0.3 mg/kg b. w. ensures adequate anesthesia, with a high level of analgesia persisting in the immediate postoperative period.

[The vascularization of the autograft in different states of the recipient bed based on data from the superselective angiography of a canine mandibular preparation].

Superselective angiography of mandibular preparations from 72 dogs has revealed that the inferior alveolar artery, tied up by a routine method, does not take part in the transplant revascularization. Binding of an intraosseous or transplanted facial artery stump with a heparin plug has revealed recanalizing vessels in the transplant, that speed up its restructuring.

[Principles of the plastic replacement of tissues in patients with head and neck tumors].

Basing on their experience, including 619 plastic surgeries for tumors of the head and neck, 412 (66.6%) of these being performed simultaneously with destructive operations, the authors validate the necessity of simultaneous plasty. They present the scheme for replacement of various defects in oncologic patients and describe some aspects of primary bone plasty in 23 patients.

[Myelochondroplasty of bone cavities and defects of the jaw bones].

A new transplant is designed which consists of an autologous vital bone marrow and dispersed lyophylized allogenic rib cartilage. With postsurgical cavities filled with this transplant, the regeneration of osteal tissue was clearly accelerated in the defect site. This reduced both the rehabilitation terms and complication incidence and improved the cosmetic effect in patients with extensive residual osteal cavities formed during pathological tissues extirpation.

[An evaluation of various methods for arthrography of the temporomandibular joint].

In 130 patients with temporomandibular joint dysfunctions several arthrographic techniques were applied, and their advantages and drawbacks pointed to. Indications to different joint contrasting techniques were established. Contrast arthrotomography combined with computerized tomography showed major diagnostic value in detection of internal joint disorders.
