Brief summary
To improve diagnostic methods for patients with laryngeal stenosis for the optimal determination of the technique of surgical treatment.
Detailed description
The study include patients with laryngeal pathology in the otorhinolaryngology clinic of the 1-city hospital at Nur-Sultan city. All patients cheek up the necessary clinical, functional, diagnostic studies and treatment measures. It is planned to examine and operate on 70 patients with laryngeal pathology. 1. To study the features of the course of stenosis of the larynx under the influence of various factors, as well as traumatic injuries. 2. To develop optimal diagnostic methods for patients with laryngeal stenosis. 3. To assess the effectiveness of endolaryngeal microsurgery in patients with laryngeal stenosis. 4. To develop recommendations for the organization of treatment for stenosis of the larynx with an increase its functional state.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline forced expiratory volume | at baseline and at 24-week postrandomization | Spirometry |
| Change from baseline area between vocal cords | at baseline and at 24-week postrandomization | MRI and CT of larynx |
| Change from basiline vocal fold vibration | at baseline and at 24-week postrandomization | Laryngoscopy and stroboscopy |
| Evaluate the motor system by recording action potential generated in muscle fibres like thyroarytenoid, lateral cricoarytenoid, posterior cricoarytenoid, interarytenoid, cricothyroid. | at baseline | Electromyography |
