It is only been 4 months since your primary rhinoplasty and we usually recommend waiting at least a year before undergoing a revision, especially in the tip area since that takes the longest time to heal. For many examples of hump removal and bulbous tip repair, please see the link below
Thank you for the question and your pictures. I'm sorry to hear that you had an unsatisfactory experience with your surgeon. It does look like there is some residual bump and the tip is still bulbous. Part of this may be swelling at this relatively early stage. In general, it is recommend to wait a year after rhinoplasty before undergoing revision. This is to allow for all of the swelling and settling to resolve. In my practice, I am not quite as rigid and have offered revision surgery as early as 9 months. At this point, I would recommend seeing a handful of consults with qualified, board-certified rhinoplasty experts in preparation for a likely revision this winter. Best of luck moving forward!
