Chin Implant Tape/dressing? Could I just remove it myself on the day of the presentation?

I would recommend discussing your plans with your surgeon.  The dressing limits the amount of edema (swelling) after surgery, and also acts to support the implant in the correct position.  It shouldn't be an issue to remove it for a brief presentation, but best to confirm with the surgeon performing your procedure to ensure the best results.  

Hello, and congrats on scheduling your surgery! Chin implants yield fantastic results, and I'm sure you'll be very happy. Each surgeon typically has their own protocol with post-operative care following a chin augmentation. After one week, you should be fine with ointment and a small bandage covering the incision area. I would recommend speaking with your surgeon ahead of time regarding his/her post-op recommendation. Thank you, and I wish you the best of luck with your surgery!

Some surgeons do not use tape in every case...discuss this with your surgeon.  It should be ok by a week after surgery.

In my experience, the tape that is used is helpful for support and to help reduce swelling post surgically. It also helps migration of the chin implant, which may be a problem depending on how the surgon chose to fixate the implant. I would check with your surgeon, but it seems like that it might be fine for a meeting or an event.
