Ear Institute of Chicago Acoustic Neuroma Treatment Results
The Ear Institute of Chicago has a combined experience with over 1000 patients with acoustic neuroma during a 20-year period. This makes the Ear Institute of Chicago one of the largest acoustic neuroma centers in the United States.
The group is well versed in all aspects of management of acoustic neuromas. The physicians are capable of performing all surgical approaches for acoustic neuroma removal, including the translabyrinthine, retrosigmoid, and middle fossa approaches. A wait and see approach is also used in selected cases depending on symptoms and the size/location of the tumor.
The type of management is individualized depending on the patient's wishes, hearing level, other neurological symptoms, and location and size of the tumor. The final choice is one that will provide the most ethical outcome.
The Ear Institute of Chicago maintains an outcome database based on the treatment of over 1000 patients with acoustic neuroma during the past 15 years. The database is used to improve treatment techniques by evaluating the group's microsurgical outcomes.
Acoustic neuroma research is a large part of the practice of the Ear Institute of Chicago. The group is currently working with Northwestern Memorial Hospital to evaluate several disease specific issues regarding acoustic neuromas. These issues include the epidemiology, the genetics, and the molecular biology of acoustic neuromas. The ultimate goal of this study is to determine the factors that lead to the best management of a patient with an acoustic neuroma.
