title: Residual high-frequency hearing in a patient with Mondini's deformity: clinical implications.
abstract: We reviewed records of a patient with Mondini's deformity who had hearing loss in the speech frequencies and preservation of hearing for frequencies above 4000 Hz. The patient seemed to be an example of a profoundly deaf child with good speech development secondary to preservation of ultra-audiometric hearing. We suggest that patients with Mondini's deformity have their ultra-audiometric hearing evaluated, and that those with profound deafness and ultra-audiometric hearing be radiographically evaluated to rule out Mondini's deformity for diagnostic and therapeutic purposes.
