I saw the RO and the ENT for the first year, followed by the ENT alone after that, now down to an annual visit. For the first year, I was very glad to have two docs examining my neck and my mouth, as they had a slightly different technique, so I felt I was getting a good checkup. As far as the MO, I just e-mail him annually with a humorous update, which he appreciates enough to forward to everyone in the department, whether they knew me or not.
