How long will it take for the tip to drop?

Thanks for your question. I would certainly advise discussing with your surgeon prior to undertaking any efforts to "push" the tip down. If there are cartilage grafts or sutures that are helping to form your tip shape you may dislodge or move something. In my opinion the tip is unlikely to drop unless it was severely ptotic to begin with. A ptotic tip or long droopy tip can occasionally  drop a few millimeters within a few years after surgery, however this is not the expected result for a tip that was simply rotated. In short please discuss your concerns with your surgeon prior to doing anything. Hope this helps.
