Hi, Broken Wing:
Kudos to you for taking care of your friend and your obvious concern for his well being.
In my experience, my primary care physician (an internist) ordered my 'original' MRI scan based on my symptoms and phoned me with the bad news that I had a large acoustic neuroma tumor. He recommended a neurosurgeon, but after a consult, I did not choose to avail myself of his services, due to his relative inexperience with AN tumors and a rather haughty attitude from his office staff.
The neurosurgeon I
did choose was very experienced and compassionate, liked and respected by other doctors, nurses and office staff. I never saw an ENT. Following surgery (successful) I underwent radiation (FSR). The neurosurgeon worked with a radiation oncologist - as a team. Although I saw the radiation oncologist weekly during the FSR treatments (5 weeks), once I finished, he basically signed off on my case, as I was fine. I've seen the neurosurgeon many times since the surgery 14 months ago. He has me undergo an MRI svcan and performs simple neurological tests as well as inquiring about my functionality and well being - and listening carefully to my responses. My primary care physician also wanted to examine me a few months after my surgery. He performed a very basic exam and asked about any problems I had (none). He saw me again, at his suggestion, in June - one year post-op - and wants to see me again in another few months, 'just to keep an eye on me', he claims. I'll see the neurosurgeon in December for another MRI and evaluation.
What I gathered from my experience is that the surgeon does your follow-up and a GP tracks you for any other problems. This doesn't appear illogical to me. The neurosurgeon
is the expert ('specialist') and can handle most anything that might arise, while a GP can handle other, non-surgical-related problems. Although a two-hour drive is a bit much, the phone is almost instantaneous. I can't speak for others or strictly define 'normal' in this situation but it's worked for me. At 4 weeks out of surgery, your friend has a way to go to complete recovery but with your help, I know he'll get there.
