Salary: anywhere from high 100's and up. I know guys that have made over a mil in a year (I am not kidding) and know guys making 160K (pretty low if you ask me). The "Bulletin" is a publication sent out by the AAOHNS and ever year or so it gives averages of salaries. They vary by region, but are usually around 250K. Salary depends on numerous factors: academic vs private practice, subspecialization, big or small city, etc. Probably the biggest factor for private guys is how good of a businessman you are.
As far as lifestyle, you have to take call, but that varies widely as well. Academic guys in the dept I'm in take call about q 14. Guys in a small town might be on q2. Your lifestyle will also vary based on the surgeries that you do. Head and neck surgeons prob work harder (hours-wise) than the others because their surgeries last longer and their patients stay in the hospital longer.
