A “trade off’ of any surgery is some scarring. The quality and the appearance of scars varies widely with the individual’s healing process, the position of the scar on the nose, and the degree of stretching placed on the scar.
The rhinoplasty operation can be done entirely through small incisions inside the nose, or by adding an incision across or at the base of the nostrils.
Although your surgeon will use his expertise and experience to hide and minimise any scarring, with some operations the scar, however small, will always be visible and with some areas of the body there is an unpredictable healing response of the scar.
Scars are always visible, they always take time to mature and the degree and quality of a scar can never be guaranteed.
