A patient with an animate foreign body in the external auditory canal obviously needs immediate help. Before removal of insects from the external auditory canal the author has used 8% Xylocaine spray against them for several years. Most insects were paralyzed in a few seconds after two or three sprays of 8% Xylocaine. It is clinically confirmed that Xylocaine is insecticidal to most insects, but harmless to stato-acoustic organs of patients.An application of Xylocaine to an animate foreign body in the external auditory canal is strongly recommended.
