[Laser diaphanoscopy for inflammatory diseases of the paranasal sinuses]. / Lazernaia diafanoskopiia pri vospalitel'nykh zabolevaniiakh pridatochnykh pazukh nosa.

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.

Endobronchial surgery of trachea and bronchi.

Bronchoscopic operative interventions were performed in 57 patients. We used photocoagulation with neodym-YAG-Laser, electrosurgery with fibroscopic diathermic snare and mechanical removal of endobronchial neoplasms. The most effective method was the laser photocoagulation, which permits removal of benign tumors, carcinoids, massive cicatrical tracheal stenosis and noninvasive bronchial cancer, help in restoring the lumen of main airways in case of nonoperable malignant tumors.

[Endoscopic laser surgery of the trachea]. / Lazernaia éndokhirurgiia trakhei.

Bronchoscopic laser operative interventions with the use of yttrium- aluminum -garnet laser were carried out in 36 patients with various pathological structures of the trachea. Laser endosurgery was applied as radical and palliative types of therapy. Endoscopic laser interventions make it possible to remove completely benign and carcinoid tumors, correct some types of cicatricial stenoses, restore continuity of the trachea, and remove respiratory insufficiency in inoperable malignant neoplasms with exophytic growth.
