Ultrasound examination of swallowing disorder characteristics in patients with oncopathology of the oral cavity

The aim of the study was to compare dynamics oral and oropharyngeal muscles contraction during swallowing in normal individuals patients with malignant tumors depending on clinical disease using ultrasound. Materials methods. included 29 aged 38–55 years (men), normtrophic, who were treated Department Head Neck Tumors Podolsk Regional Oncology Center for tongue, floor mouth oropharynx. Among them, there 12 cancer lateral tongue surface, 9 - mucosa 8 – base cancer. Scanning performed sagittal frontal planes a 7.5 MHz sensor two modes (B M) at rest several stages TOSHIBA device (Model USDI-A500A/EL; Serial No. ELA14Z2082). B-mode main one all studied areas where image frame vertically lined up. act assessed M-mode (a length axial movement). obtained indicators compared ones. Results. work carried out verify musculoskeletal complex involved swallowing. Measurements revealing violation act, namely decrease longitudinal examination sublingual muscle group diagnosed floor. In addition, deviation displacement healthy contralateral side preserved function surface revealed by ultrasound act. Conclusions. showed decreased 7 % projection anterior belly digastric 3.5 times. cancer, mentohyoid distance merely 4 mm reduced swallowing, only 5 %. lowest reduction distance, about when (in people 8–12 mm) B-mode, 2 mm.
