Dr. Sperling restored my hearing! He wrote the textbook on Stapedectomy surgery for otosclerosis. Other top specialists (in Boston & NYC) sd they didn’t think they could and left me in tears re potential side effects. I had lost most of the hearing in my left ear due to otosclerosis (build up of calcium on stapes bone). I’m a college professor in RI and had a hard time hearing students in the back of the room or comments from colleagues in meetings. Wish I had not wasted time w other docs!
