I'm not sure why you posted your question in this portion of the forum, but there are many risks involved in any PS procedure, inclusing rhinoplasty.
First off, if you do end up choosing a surgeon, you will have to literally "sign almost all of your rights away", unfortunately. I do not agree with this, but surgeons will make you sign a plethora of forms stating that if the patient's desired results are not achieved, it is not due to any negligence on the part of the surgeon. Sometimes, it is
due to surgeon error, lack of asthetic compromise on the part of the surgeon, and/or lack of expertise. These clauses were originally utilized as many patients had and/or developed Body Dysmoprhic Disorder, had unrealistic expectations and demanded revisions, or demanded multiple revisions. Now the clauses are primarily utilized due to greed on the part of surgeons, lack of expertise, and/or more and more error on the part of the surgeon.
As far as risks, the most obvious is that you will not be satisfied with your results. This usually occurs when a patient has unrealistic expectations (i.e.: bringing a picture of a celebrity to a consultation that "you want to look like").
There are also medical risks which can include but are not limited to issues from anesthesia (death, blood clots, strokes, heartbeat irregularities including heart attack, paralysis, brain injury, neurological complications, and/or airway obstruction). In general you can also have issues due to infections, radical changes in blood pressure, aspiration issues, blood loss, and/or death.
As per the ASAPS, post surgery one must be concerned with the following:
"Skin Death or Necrosis, Asymmetry, Slow Healing, Numbness/Tingling, Irregularities, as well as Seroma". Please note, seroma does not apply to rhinoplasty, so that is one thing you do not have to be concerned with.
Other preexisting medical conditions and/or lifestyle choices can also increase PS risks. These include your weight, cigarette smoking (affects healing time and ability to heal), heart problems, CNS issues, oral contraceptive use and/or hormone replacement therapy treatment.
Why not post some pictures so you can get honest feedback from some of the forum members?
I hope I have answered your question. Good luck to you!!!
