Introduction. Chronic rhinitis occurs more often in patients; it’s symptoms deteriorate their quality of life, affect sleeping, daily activity, and sometimes cause complications. The treatment depends on the clinical symptoms. In case of inefficiency of conservative therapy, surgery is indicated. Choosing an exact surgical instrument is still controversial.Objective. The aim of our study is to compare using semiconductor laser (wavelength 1.56 mkm) and radiofrequency (4 MHz) in patients with chronic rhinitis.Materials and methods. 60 patients with chronic drug-induced rhinitis aged 19–80 years were recruited and divided into two equal groups. All patients underwent surgical procedures: semiconductor laser (IRE-Polus) and radiofrequency (Ellman Surgitron) inferior nasal turbinate reduction. To assess and compare the healing process in two groups we used endoscopy and active anterior rhinomanometry. All patients filled out the SNOT-20 questionnaire. For the mucociliary clearance evaluation saccharin test was used. We observed patients during 12 months.Conclusion. Both, laser and radiofrequency, techniques are effective in patients with chronic rhinitis. In laser group shorter healing period was observed, what leads to rehabilitation shortening and life quality improvement.

Introduction. Chronic nasal congestion caused by edema of inferior turbinate affect 20% of population and strongly influences their quality of life. Pharmacological treatment of chronic rhinitis is considered to be the first line therapy. However, if conservative treatment is not effective and clinical signs are not disappearing the question about relevant surgical treatment is arising. Nowadays there are many methods of exposure on mucosa of the inferior turbinate. Considering high incidence of the pathology surgical treatment is of current importance in modern otorhinolaryngology.Objective. Assessment of the effectiveness and comparison of the period of rehabilitation after submucosal laser destruction by laser beam with wavelength 1,56 and after submucosal destruction by radiosurgical instruments Ellman Surgitron with a frequency of 4 MHz in patients with chronic rhinitis.Methods. 60 patients were included into the study aged from 18 to 80 years old with chronic rhinitis. All the patients were admitted to the department to perform surgical treatment. Semiconducted laser with wavelength 1,56 and radiosurgical instrument Ellman Surgitron with frequency of 4 MHz were applied to the treatment. We assessed SNOT20 score, endoscopic features, anterior active rhinomanometry and saccharin test results in all patients following the surgery.Conclusions. The data we have obtained provide the basis for choosing semiconductor laser as more effective and safe technique for the treatment of patients with chronic rhinitis.

The objective of the present study was to determine the optimal parameters of radiation of the CO2 laser during the surgical intervention for the treatment of the patients presenting with otosclerosis. The experimental part of the study was carried out with the use of the isolated temporal bones. Under the clinical conditions, the patients with the tympanic and mixed forms of otosclerosis underwent stapedoplasty with the use of the CO2 laser. It was shown that the use of the CO2 laser at different stages of stapedoplasty considerably reduces the risk of development of the post-operative complications. It is concluded that the proposed stapedoplastic technique makes it possible to decrease the duration of post-surgical rehabilitation of the patients suffering from otosclerosis.

Introduction. It is not always possible to create a perforation in the footplate of the stirrup with the help of classical microinstruments during stapedoplasty, which will exactly correspond to the required parameters, moreover, these tools can be dangerous in some cases, since it is possible to provoke the footplate to enter the ear labyrinth, mobilizing it.Aim. To determine the efficacy and safety of various methods of stapes surgery in otosclerosis with an assessment of the frequency of intra- and postoperative complications.Materials and methods. In the Clinic of Ear, Throat and Nose Diseases of the I.M. Sechenov First Moscow State Medical University of the Ministry of Health of Russia (Sechenov University) a number of experimental and clinical studies were conducted, partial results of which we decided to retrospectively compare and analyze. The data of the first group of patients were taken from the results of a study with a CO2 laser. The data of the second group of patients were obtained from the results of a study with a diode (blue) laser with a wavelength of 445 nanometers. The data of the third group of patients were collected from archival data of medical histories from 2020 to 2022, who used a set of micro-tools for stapedoplasty (manual micropeforator, microneedle).Results. The data obtained showed similar results in the CO2 and blue laser groups. The main difference in the group of patients who underwent stapedoplasty with classical microinstruments was a longer operation time compared to laser stapedotomies, as well as a greater number of intraoperative difficulties associated with the mobilization of the foot plate of the stapes during manipulations with a manual perforator.Conclusions. The use of blue laser and CO2 laser in stapedotomy procedures shows promising results in terms of surgical accuracy and speed of the operation. Further research should compare the long-term effects of these three methods to determine the most effective and safest.
