After insertion of silicone you will soon feel the widening of the nasal tip.

This happens because of the lower lateral cartilage that is pushed to the outer part due to silicone that is stuck in between the lower lateral cartilage

At first the end will turn out looking sharp and narrowed but later as the time goes by the silicone will break in between the lower cartilage and make the tip flat.

The picture below is the revised form of the widened nasal tip due to insertion of silicone.
