My father had surgery performed at OHSU by Doctors McMenamee and Delashaw two years ago. His was for a regrowth 20 years after his first removal. Even though the doctors spent hours picking through scar tissue, his outcome was great! He was up and walking in 8 hours and released in 72 hours. The care he received was great. He was already deaf, so hearing preservation was not an issue. The doctors preserved his facial nerve function, for which we are very happy. Please let me know if I can answer any other questions for you.
