I am still a resident, so take this with a grain of salt... Overall, from what I've heard, the market is excellent for ENTs practically everywhere. Recent graduates from my program (which is not "elite") have had their pick of practices to join. You will generally make less money starting out at more desireable practices/locations (i.e. $125-175K/yr). The advertisements you may see for starting salarys of $300-400K/yr usually have disadvantages (i.e. rural, etc.) An established partner in a general ENT private practice will make $250-300K/year or more (sometimes much more) depending on productivity/work ethic/business savvy/etc. These numbers will probably vary depending on area of the country, type of practice, etc. Academic ENTs will probably make somewhat less than established private practice ENTs, but the difference is not what it used to be.
Would be interesting to hear the take of some of the attendings on this board.
