Features of determination of masticatory efficiency at patients with postoperative defects of an oral cavity

Abstract

Resume. The aim of the study was to improve the determination of masticatory efficiency in patients with oncopathology of the oral cavity before and after surgery. For this purpose, the analysis of masticatory efficiency in dynamics was performed using a two-color chewing gum in 29 patients with tumors of the tongue, oral mucosa and lower jaw. After surgery, masticatory parameters decreased compared to the weekend and did not recover for 7 days after surgery. In patients diagnosed with stage I-III mandibular cancer, masticatory values are below 0.5 (0.34±0.04; 0.28±0.03; 0.24±0.03), indicating poor bolus formation. This method is informative for the formation of the bolus, taking into account not only the presence of teeth, but also the function of the muscles involved in chewing. Key words: masticatory efficiency, defects of the oral cavity, tumors of the tongue, the bottom of the oral cavity, the jaw.
