Figure 4: Probe insertion technique. (A) The TEE probe handle should be hung or held by an assistant to allow free movement of the shaft. (B) The probe should be inserted maintaining midline to avoid common sites of obstruction at the arytenoid cartilages and pyriform fossae. (C) Once at the base of the tongue at midline, a “chin lift” maneuver will facilitate passage by opening the esophagus. (D) Once in place, a bite block previously loaded into the probe should be placed to avoid damage by the teeth on the probe.
