Perforation of tympanum, resulting in vestibular disease, redness, ulceration and hemorrhage of tissue that lines the ear canal, blockage of ear canal by plugs of paste like wax, ataxia (due to rupture of the tympanic membrane and lesions to the vestibular system), anorexia, restlessness, unilateral facial paralysis, debilitation, hearing loss and head shaking have all been reported in association with ear mite infestations (Ladds et al., 1972; Duarte and Hamdan, 2004; Duarte et al., 2004; Krametter-Froetscher, 2006 and Ferry et al., 2011).
