My son had a traumatic injury to his ear which perforated almost his entire eardrum and dislocated one of the small bones of his inner ear. His hearing loss was severe. Dr. Kohan is a miracle worker!! He reconstructed his ear and now, 6 weeks after surgery, his hearing is better than normal!!! We will be eternally grateful. I would highly recommend Dr. Kohan and if anyone in my family needed surgery, I would only go to Dr. Kohan. In addition, his office staff is top of the line. Any time I called with a question, to schedule an appointment, or to get copies of medical records were handled quickly and professionally.
