[Application of ultrasonography in diagnosis and treatment of acute inflammation of soft tissues in maxillofacial region and neck].

We investigated the value of ultrasonography (USG) and ultrasound-guided aspirations in diagnosis and treatment of acute inflammation of soft tissues in maxillofacial region and neck. We performed 174 USG in 136 patients (73 with abscesses and phlegmons, 27 with acute lymphadenitis, 16 with inflamed cysts, 12 with parotitis, 3 with sialolithiasis and 5 with diseases, simulated acute inflammation). Ultrasound-guided aspirations performed in 35 patients. We considered USG to be useful diagnostic tool in acute inflammation of soft tissues in maxillofacial region and neck. USG allowed to determine localization and stage of inflammation, discriminate it from non-inflammatory diseases and improve assessment of its dynamics. Ultrasound-guided aspirations was a valuable tool for diagnostic and treatment purposes in inflamed cysts.

[Peculiarities of diagnosis and treatment of patients with hyposialosis].

33 patients with complaints of hyposalivation (21 in a 33 with syaloadenopatya and 12 in a 33 with syalosis out of the acute stage of disease) were examined. Complex examination of the saliva glands, analysis of the haemokynes in the various mediums of organism and thyoles compounds in the blood plasma was carried out. Tendency to increase in contents of haemokynes in the mixed saliva and in the tissue samples (from low in the syaloadenopatya to expressed in the syalosis) was revealed. Reduction of thyosulfide index in the blood plasma of these patients was determined. Use of antioxidant remedy in complex treatment of syaloadenopatya and syalosis was substanciated in this paper.

[The composition and structure of salivary calculi (sialoliths)]. / O sostave i strukture sliunnykh kamnei (salivolitov).

Composition and structure of more than 50 sialoliths were examined to optimize the treatment of sialolithiasis. Infrared spectroscopy, x-ray phase analysis, optic and electron microscopy were used in examinations. The concrements consist of organic and mineral substances, the former ones predominating. Mineral phase is represented mainly by carbonate-containing hydroxylapatite. The structure of the concrements is concentrically lamellar, in some of them the mineral phase predominates in the central parts of stones, in others in the peripheral parts; stones with regular distribution of the mineral phase along the stone section are quite frequent. The authors conclude that search for the optimal parameters of hypershock exposure to disintegrate the concrements is going to be rather difficult because of the complexity of their structure. They distinguish two trends of this research: (1) specification of the optimal parameters of hypershock exposure and (2) combination of hypershock wave exposure and litholytic solutions.

[Comprehensive radiologic examination in the diagnosis of parotid salivary gland diseases]. / Kompleksnoe luchevoe obsledovanie v diagnostike zabolevanii okoloushnykh sliunnykh zhelez.

Comprehensive x-ray, ultrasonic and radionuclide examinations of 131 patients with chronic sialadenitis (n = 50), sialosis (n = 59), sialolithiasis (n = 9), autoimmune disorders (n = 6), and bulky processes (n = 7) of the parotid salivary glands were carried out. The diagnostic potentialities of each method in every of these conditions were analyzed. No correlation between the structural and functional disorders of the parotid glands could be traced. A complex of radiologic methods is necessary to fully assess the anatomic and functional status of the parotid glands. An algorithm of examination in such conditions is presented.

[End-to-side type of plastic repair of the facial nerve branches]. / Plastika vetvei litsevogo nerva po tipu konets v bok.

In 19 rabbits, lower branches of facial nerve were experimentally sectioned and sutured to its middle branches to form a 'side to end' pattern with 2 to 3 epineural sutures. Morphological investigation showed that regenerating axons of the middle branch penetrate into the sutured trunk and grow further. The technique was applied in 7 patients. Full functional recovery was evidenced in 4 of them. The technique is recommended for clinical routine.
