Research Summary

Aaron D. Tward M.D., Ph.D., is a board-certified, fellowship-trained surgeon who specializes in the diagnosis and treatment of disorders of the ear and skull base.

Dr. Tward has particular clinical interests in cochlear implantation, management of benign and malignant tumors of the skull base including acoustic neuroma (vestibular schwannoma), surgery for chronic otitis media, stapedectomy, superior semi-circular canal dehiscence repair, and endoscopic surgery of the ear and skull base.

Dr. Tward’s research interests include tumor biology, the genetics and genomics of disorders of the head and neck, and clinical outcomes of surgery of the ear and skull base.
