Prognosis of Complications at Surgical Treatment of Benign Parotid Tumors

Abstract

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.
