Why don't some Rhinoplasty drs. post a lot (more) before/after pics on their website? Can I see many more in-office?

In most cases, the number of photo examples showing rhinoplasty results is reflective of how often that particular plastic surgeon performs a certain procedure. Plastic surgeons who perform rhinoplasty on a very regular basis (several times per week) will have many more examples because, simply put, they do more than others. This is a very important factor that you should consider when deciding on a plastic surgeon to perform your rhinoplasty. 

Before/after photos of the surgeon's work? You should definitely see many before and after photos of the surgeon's work since that is what you will be getting. If he cannot show you natural looking noses that he has done like yours see another surgeon. Don't rely on imaging!
