The aim of the work was to develop effective integral characteristics of the express assessment of the elasticity index and elastotype in patients with tumors of the parotid salivary gland, that made it possible to obtain a certificate of official registration of the program for electronic computers.

The development of clinical medicine to a certain extent depends on the level of prognosis of surgical patients. In prognosis, the method of regression analysis is widely used. Prognostic scales help to assess the risk of complications in patients after surgery, which allows the use of relatively more effective diagnostic and therapeutic measures. The aim of the study was to develop the integral mathematical characteristics of the prognosis of the outcome at surgical treatment of benign parotid tumors, adequately describing the pathological process. When constructing a mathematical prognostic model, its parameters were subject to the requirement of their efficiency above ??95% according to the t-criterion. The purpose of the mathematical modeling was to statistically adequately link the complications of surgical treatment of parotid tumors with clinical and diagnostic data. The developed mathematical model made it possible, on the basis of significant clinical and diagnostic data in patients, to identify prognostic factors for the development of paresis of the mimic muscles of the face in the surgical treatment of benign parotid tumors. Based on the studied correlation analysis, the significant (??0.05) clinical prognostic factors for the development of paresis of the mimic muscles of the face after the operation of partial superficial parotidectomy were revealed: gender, patient’s age, cytological result, sonoelastographic strain-ratio value, computer tomography or magnetic resonance imaging of tumor size. Also, the prognostic factors for the development of paresis of the mimic muscles of the face during the parotidectomy and the extracapsular dissection of the lower pole of the parotid gland were determined. In the result the certificate of the official registration of the computer program was received. The possibility of prognosis of the complications of surgical treatment in patients with parotid tumors has also been developed in order to reasonably carry out more effective therapeutic and rehabilitation measures.

the research was performed on 117 patients of Uzbek ethnicity with malignant tumors of maxillo-facial area. Results of the research showed that developing of malignant tumors of maxillofacial area involving face skin and oral mucosa was associated with the carrier of a heterozygous Arg/ Pro genotype.

Intraparotid facial nerve schwannoma (FNS) is very rare disease that is difficult to diagnose; thus, there is no established treatment strategy. We herein report two cases of intraparotid FNS and highlight the diagnostic and surgical approach. The first patient presented with painful parotid mass. We performed superficial parotidectomy as a diagnostic treatment. The continuity of the nerve was interrupted when we attempted to completely resect the tumor. After resection, we carried out reconstruction of the facial nerve using neurorrhaphy with end-to-end anastomosis. A histopathological examination revealed findings of intraparotid FNS. The House-Brackmann (HB) grade was II at a 2-year follow-up examination. No recurrence has been seen in the 2 years since surgery. The second patient presented with gradually progressive swelling in the right parotid region. The patient underwent tumor removal without parotidectomy via binocular magnification and a diode laser. As a result, the patient's facial nerve function was intact at an 8-year follow-up examination (HB grade I). Tumor recurrence was not identified. Microsurgical and diode laser approaches in the management of intraparotid FNS resulted in a better overall facial nerve function without recurrence. Resection of intraparotid FNS with microsurgical and diode laser approaches should be included in a management algorithm, with prioritization of preservation of the facial nerve function.

For the first time in its history, the proceedings of the 11th International Symposium on Computer Science, Computer Engineering and Educational Technologies (ISCSET-2022) is published in a special issue of the Embedded Self-Organizing Systems journal of the Chemnitz University of Technology
