Summary
- Neurotologist/lateral skull base surgeon in the Mount Sinai Health System with expertise in the treatment of acoustic neuroma (also known as vestibular schwannoma), glomus tumors (head and neck paragangliomas), cerebrospinal fluid (CSF) leaks, and facial nerve disorders. I have additional extensive experience in removing cancers of the ear and performing minimally invasive endoscopic surgery for tympanoplasty, ossicular chain reconstruction, stapedectomy for otosclerosis, and removal of cholesteatoma. I work closely with our audiology team to restore hearing via cochlear implant and bone anchored implant surgery.
I am the editor of the Mount Sinai Otolaryngology surgical video series on Youtube: https://www.youtube.com/playlist?list=PLqLDR0CTP9_rneZp5ZbQrFB3vIVTQN9zq
