Will Dark-skinned Patients Getting Septoplasty Have Unslightly Scars Around Nostrils? (photo)

There should not be external scars with a septoplasty, as the incisions are made inside the nose. In general, a small external scar is left during an open rhinoplasty. The goal is to make this scar minimally visible, and it heals rather nicely when the procedure is performed with precision. I would recommend doing your homework and seeking out a board certified surgeon who has a great deal of experience. This will ensure you obtain the best possible result. I hope this helps, and I wish you the best of luck.

For a rhinoplasty, sometimes incisions are used on the outside of the nose.  However for a septoplasty, to correct a deviated septum, all the incisions can be designed so that they are hidden inside the nose.  Whether you have light or dark skin, the incisions will not be seen if properly designed.  

The photos you provided the link to show a rhinoplasty scar (across the columella) including alar base reduction scars (across the nostrils).

A standard septoplasty places a hidden incision inside the nostril area so it shouldn't be visible. I've not heard of keloid scarring in this area.

You can look at my web reference below to get a better idea where the septoplasty incision is placed and what surgery entails.
