[Low-frequency ultrasonic therapy in combined treatment of chronic maxillary sinusitis].

The author presents the results of application of intrasinus low-frequency ultrasound in the treatment of 61 patients with chronic purulent maxillary sinusitis. Compared to the control group of 10 patients given conventional treatment, ultrasound-treated patients responded better. Thus, intrasinus low-frequency ultrasound used in patients with chronic purulent maxillary sinusitis makes the treatment cheaper and faster. Simple and convenient in management, the above ultrasonic equipment can be applied both in hospitals and outpatient setting.
