I get asked this question a lot. There is no absolute number after which rhinoplasty becomes impossibly dangerous or doomed to fail.
However, it is a rule of thumb that the surgery is wrought with more difficulty, has a higher complication rate, and has the potential to lead to permanent problems the more surgeries one undergoes.
There are several reasons for this:
The first, scar tissue - each time the skin envelope is elevated from the underlying infrastructure of the nose it is traumatized it undergoes soft tissue contracture and it potentially weakens. The soft tissue contracture may thin the skin rendering it stiffer and thinner and less forgiving to hide any underlying imperfections.
Secondly, revision rhinoplasty if done in a reductive manner or done in a way that does not restore structural support to the nose has a possibility of weakening the infrastructure of the nose. Not all revision rhinoplasty is done is this way, in fact, in my practice, most of the time revision is performed to strengthen support that has been lost. However for other revisionists, further reduction is a rule leading to potential further weakening of the nose.
Also to take into consideration, the emotional condition of the individual changes when undergoing multiple revision procedures; it’s quite a different story when one is seeking primary rhinoplasty. The patient is full of hope, full of expectation and seeking to create improvement to the shape of the nose. The revision patient is one who has undergone disappointment, has potentially been injured or even impaired by a previous surgery. This causes this person, understandably, to be more skeptical, to be more anxious, and to be more risk adverse undergoing revision or multiple revised procedures. In some cases it causes the individual to pay undue or excess attention to the nose – in some cases becoming obsessive over very small details. In those situations it transforms a person who was once quite reasonable and had realistic expectations into a one who is unreasonably perfectionist about the outcome of the procedure.
Lastly, the anatomy has changed. The natural landmarks of the nose in primary rhinoplasty serve as guideposts for the surgeon, though which he or she can navigate through the anatomy of the nose – allowing them to create changes that are safe predictable and reliable. When the anatomy has been distorted by previous surgery, these familiar landmarks are no longer available causing a compromised baseline. In some cases this increases the complexity and difficulty of the surgery.
I would advise to seek out a consultation from a rhinoplasty specialist who performs a high volume of revisions. Despite these challenges, in the hands of an experienced surgeon, even a multiple revision rhinoplasty can lead to a great outcome!
