Combined Atresia Microtia (CAM) Repair: A New Method of Reconstruction of Form and Function in Congenital Aural Atresia and Microtia

  • Joseph B. RobersonJr.Email author


A new surgical procedure to repair both the form and function deficits associated with congenital aural atresia and microtia is described – combined atresia microtia (CAM) repair. In properly selected patients, using the evaluation acronym HEAR MAPS, surgery can return hearing to normal ranges while providing excellent cosmetic repair. The procedure has been performed in one center on over 200 patients and is possible at 3 years of age – within the critical period of auditory development.
