[The diagnosis of malignant neoplasms of the naso- and oropharynx by using computed magnetic resonance tomography in an ultralow field].

MR tomography examination of 51 patients with maxillofacial or cervical cancer provided adequate diagnostic information especially in the absence of bone involvement. The method proved efficient in differentiating tumors with inflammation, in tumor localization, evaluation of its size and spread, outline, structure, invasion. It is safe, noninvasive. For differential purposes the technique is most beneficial in impulse double echo mode with proton density and T2.

[Laser diaphanoscopy for inflammatory diseases of the paranasal sinuses].

After puncture or catheterization of the accessory nasal sinuses, the intensity of helium-neon laser inserted into the cavity under examination was recorded by means of a specially designed manipular. The laser beam intensity that penetrated the wall was found to correspond to the degree of its inflammation. The high level of objective information obtained allows assessment of pathological developments and therapeutic effectiveness.

[Provision of artificial ventilation of the lungs during endolaryngeal surgical interventions using a high-energy laser].

To ensure controlled lung ventilation in endolaryngeal surgical interventions, using a high-energy laser, use was made of normal frequency jet ventilation (NFJV) and high frequency jet ventilation (HFJV) through a non-inflammable fluoroplast catheter supplied at a distal end with a device fixing it in a central position. HFJV seems preferable, as endolaryngeal manipulations become more convenient. The study was performed in 118 patients. Venturi effect was observed only during ventilation through a tracheostomic canule. It has been established that, unlike NFJV, in HFJV gas exchange parameters are much better, though oxygenation in NFJV is satisfactory in all the patients.

[Light-guide instruments for low-intensity laser therapy in ORL practice].

Manipulators with monofibre light-guides have been specially designed for otorhinolaryngologic instruments commonly used in routine drug therapy for intracavital treatments. Quartz enclosed in a protective polyethylene sheath is used as the monofibre light-guide with a light conductor 400 microns in diameter and 2 to 3 m in length. It can be built in the following instruments: an ear catheter, a maxillary sinus lavage cannula, a subclavian artery catheter, and a laryngeal bougie. The use of monofibres allows considerable widening the application field of the low power laser therapy in otorhinolaryngologic practice. Moreover, in compliance with human engineering requirements it managed to preserve most standard manipulations otolaryngologist makes use in the course of routine clinical practice with conventional instruments.
