Electrosonography (ESG)

Also called “sonography” and sometimes “ joint vibration analysis”, Electrosonography utilizes computer based vibration sensitive transducer technology that quickly and non invasively records joint sounds and vibrations originating in the temperomandibular joints ( TMJ ). The patient wears a lightweight headset that positions two sensors over the joints. The patient is instructed to open and close and the information is captured in a few minutes and analyzed.

Bone transmission of sound is so rapid that a study of joint sound with a stethoscope may not even discern which side the sound is coming from and can be subjective. Data captured by Sonography captures information from both joints simultaneously and the information can be played back at will giving Dr. Sahota additional insight to joint status and function.
