Purpose: To increase the efficiency of treatment and rehabilitation of patients with chronic cicatricial stenosis of the larynx and trachea using laser light after reconstructive surgery on the larynx and trachea. Material and methods. 40 patients with chronic stenosis of the larynx and trachea were divided into two groups: Group I (main) – 20 patients who had laser therapy sessions in postoperative period and Group II (controls) – 20 patients who had no laser therapy. All patients were examined with laser Doppler flowmetry using laser analyzer LAKK 01 with a single-channel tissue probing option. Laser therapeutic apparatus Mustang 2000 with a laser head generating in the red spectrum (wavelength 0.63–0.65 μm, pulse-periodic mode, frequency 80 Hz) was used for laser sessions. Average energy density was 1.5–3.0 J/cm2 . Laser therapy course consisted of 8–10 sessions with average exposure time 5 minutes per irradiated zone; and in case of extensive wound defects, total exposure time was increased by irradiating several fields on the wound surface.

We have proposed an original approach to the combined treatment and rehabilitation of the patients presenting with cicatrical stenosis of the pharynx and trachea with the help of the following techniques: multichannel electrical stimulation with biopolar pulsed currents (based on the new highly efficacious 1-channel Miomodel-10 electrostimulator) and instant diagnostics by laser Doppler flowmetry. The study demonstrated the appreciable improvement of microcirculation in the treated patients that increased the effectiveness of their rehabilitation and allowed for the favourable prognosis. Key wrds: electrical stimulation; microcirculation; cicatrical stenosis of the pharynx and trachea.

It is shown that staged individual special respiratory exercises targeted at nervous-muscular apparatus of the pharynx and trachea improve external respiration function, activate blood flow and venous-lymphatic outflow in the neck area with stimulation of reparative processes in combined postoperative treatment of patients with cicatricial stenoses of the pharynx and trachea.

Based on their 40 years' clinical experience in treating patients with laryngeal and cervical tracheal stenoses of various etiology, the authors consider that circular trachectomy, by anastomosing laryngeal cartilages, may be performed by highly skilled specialists only at specialized and well-equipped institutions. In cases of chondroperichondritis of cartilages of the larynx or trachea in the presence of paralysis of the vocal folds, it is necessary to make stepwise reparative and plastic operations that can be performed at the ENT clinics having experience in laryngeal surgery.
