Oculo-auricular phenomenon secondary to vestibular dysfunction.
The oculo-auricular phenomenon consists of coactivation of the ocular rectus lateralis and the posterior muscles of both ears (transverse auriculae and obliquus auriculae muscles). This coactivation produces a bilateral curling of auricles during extreme lateral gaze that can be observed in as much as an 80% of the normal population. We herein describe a 26-year-old man who presented a transient oculo-auricular phenomenon in the course of a vestibular vertigo.
