This grooved director designed by Drs. Anderson and Hwang greatly simplifies retrieval of the olive tipped probe. When the grooved director is placed in the proper position under the inferior turbinate, the olive tip probe is easily felt to be in the groove and is engaged by the key hole design which engages the olive tip and prevents posterior migration of the olive tip that can occur with a standard grooved director. It also eliminates the posterior migration of the tip of the probe at intubation.
