Is Triple Plication common practice?

Triple plication seems unnecessary. The most common practice is to do one or two layers. I believe most surgeons do a 2 layer plication.

Your surgeon should be able to better explain what you can expect in terms of results. When selecting a surgeon, review before and after photos on the surgeons' websites and schedule a consultation with those that meet your criteria. Select the one with whom you feel most comfortable and confident. Specific techniques and the rationale behind them can be explained at your consultation. It's easy to say one technique is preferred over another, but the question you want answered is "why".
