Should I ask the surgeon to also remove my Darwin's tubercle? (Photos)

Yours is not that pointy or even noticeable so I would leave it alone.  Removing the tubercle is simple but difficult to get exactly the right contour and that could look weird so I advise against it.

Dear thestorm,This is a personal decision.  You can make the incision inside the helix and lift up the skin to avoid an unsightly scar.  It is not distracting, just a matter of personal preference.Best,Dr. Nima

The removal of the Darwin’s Tubercle is not necessary unless it disturbs you. With a skilful resection technique, there will be no visible scar after the removal of the tubercle. Neither a conchal resection nor full anaesthesia is necessary if the otoplasty is carried out with the Merck Stitch Method and the patient is older than 11 years.

at the same time as  your otoplasty.  Its not terribly noticeable and I would agree with your surgeon to leave it for now and then decide later.  It can easily be done under local in the office if you did want it reduced.  Very few people would notice this tubercle you appreciate and again, most would not even notice that.  My suggestion is to leave it alone.
