[Scientific and practical contribution of professor M.F. Tsytovich in the development of domestic otorhinolaryngology (to the 150th anniversary from his birth)].

The article presents biographical information about Professor M.F. Tsytovich, reflecting his scientific and practical contribution to the formation and development of domestic otorhinolaryngology, to the training of scientific and pedagogical personnel, as well as characterizing his social activities in the first half of the twentieth century.

[The application of the computer technologies for the mathematical simulation of the ethmoidal labyrinth].

The objective of the present work was to study the relationship between the dimensions of the ethmoidal labyrinth and the skull in the subjects differing in the nose shape by means of the factorial and correlation analysis with the application of the modern computer-assisted methods for the three-dimensional reconstruction of the skull. We developed an original method for computed craniometry with the use the original program that made it possible to determine the standard intravital craniometrics characteristics of the human skull with a high degree of accuracy based on the results of analysis of 200 computed tomograms of the head. It was shown that the length of the inferior turbinated bones and the posterior edge of the orbital plate is of special relevance for practically all parameters of the ethmoidal labyrinth.

[Mediafixation of the vocal cord through the external approach in the patients presenting with unilateral laryngeal paralysis].

The objective of the present work was to develop a method for the modification of the vocal cord during the treatment of the patients presenting with unilateral laryngeal paralysis taking into consideration individual peculiarities of stereotopometric characteristics of the larynx in the subjects of different gender, neck structure, and body constitution. The earlier proposed method of laryngostereotopometry was employed in this study. The following body features were measured prior to surgery: the total length, acromial diameter, chest circumference, neck length and circumference; the degree of the fissure of glottis closure was measured by transnasal fibrolaryngoscopy.

[The use of laser Doppler flowmetry for the estimation of the influence of intranasal medications on microcirculation in nasal cavity mucosa].

Aim Of The Study: to investigate the influence of various intranasal medications on the microcirculatory bed in nasal cavity mucosa using the original method of laser Doppler flowmetry.

Methods: this comprehensive study of the influence of intranasal medicines on nasal cavity mucosa using laser Doppler flowmetry was designed to evaluate the mucociliary clearance, breathing efficiency of the nose, and subjective symptoms of its impairment. The outcomes of a single application of intranasal medications were estimated in 90 rhinologically healthy subjects; in 15 of them, the micrcirculatory blood flow in the nasal cavity was investigated in the early postoperative period with the use of intranasal decongestants and irrigation products.

[The clinical study of tympanic membrane mobility with the use of the autodyne technique].

Aim Of The Study: to estimate the possibility of application of the autodyne method for the detection of nano-displacements of the tympanic membrane and diagnostics of ear diseases.

Methods: nano-displacements of the tympanic membrane were revealed with the use of the original laser-assisted autodyne technique for the measurement of nano-vibrations. The majority of the measurements were performed in the free auditory field.
