Dr. Darius Kohan is truly a master at his craft. He performed 2 surgeries on each of my ears, one being a Tympanomastoidectomy (repair of large hole in eardrum with grafting, and repair of hearing bones) as well as a Tympanoplasty (repair of large hole in eardrum with grafting needed). The outcome of both of these surgeries has been life changing! Thanks to Dr. Kohan, I went from having a 65 bd hearing loss, to now having normal hearing levels. There is NO one better in the field of Otolaryngology, I will trust no one else with my ears besides Dr. Kohan!
