Abstract
Aim – to substantiate the safety of using a laser beam with a wavelength of 445 nm during stapedoplasty by means of an experimental physical model.
Material and methods. Together with physicists from the Russian Engineering Club LLC, a physical experimental model was created to theoretically substantiate the use of a surgical laser with a wavelength of 445 nm during stapedoplasty at its various stages.
Results. Based on the physical calculations carried out during our study, we came to important conclusions regarding the effect of laser radiation on the structures of the inner ear during the stapedoplasty process. It was found that even if the value of the parasitic (damaging) radiation energy is 10 W (maximum value) with an average pulse duration used for perforation of the footplate of the stirrup is 0.15 s, its effect will not lead to any significant thermal effect on the perilymph.
Conclusions. The obtained data serve as a basis for further research and improvement of laser technologies in the field of otosurgery. As part of our study, we anticipate the need for additional histological analysis based on the results obtained. Despite encouraging findings regarding the safety of parasitic laser radiation in the context of thermal exposure to perilymph, histological examination represents an important next step for a deeper understanding of structural changes in the tissues of the inner ear.
