METHOD FOR EVALUATING MOBILITY OF RECONSTRUCTED LARYNX Russian patent published in 2006 - IPC A61B8/00 

FIELD: medicine, oncology.

SUBSTANCE: the present innovation deals with predicting organic body alterations at applying ultrasound waves and could be applied for evaluating mobility of reconstructed larynx after its resection in case of cancer. One should fulfill ultrasound transverse scanning of cervical area in frontal plane. Moreover, ultrasound sensor should be placed at the upper edge of the remained thyroid cartilage plate to move it gently along median cervical line. Sensor's movements should be accompanied with penduliform vibrating movements around its axis being synchronous to natural laryngeal respiratory movements. It is necessary to fix a sensor in a point of the best visualization of mobile laryngeal elements to increase the amplitude of sensor's movements. Under conditions of induced phonation one should evaluate the degree of joining a healthy and an operated arytenoid cartilages and, also, substituting tissues, alterations in position of vocal cords and the degree of vocal fissure jointing.

EFFECT: higher accuracy and efficiency of evaluation.
