Although using your own tissue is ideal in Asian rhinoplasty, there are potential complications that can arise.
One of the main complications is that of resorption of the graft material.
Resorption means that your body absorbs or gets rid of the grafted material in your nose. Even though the tissue is your own, when the graft is inserted into the bridge of the nose or along the columella to increase the nasal tip, the graft can partially or fully decrease in size. This resorption happens in Asian rhinoplasty because the grafted material does not have its own blood supply. Therefore, when the graft is inserted, the blood vessels need to grow in with an adequate amount of time.
There are three main graft materials that can be inserted into the nose in Asian rhinoplasty.
One is Cartilage. Cartilage is often removed from the ear or the rib.
The other material is Dermis. The dermis is the skin with the outermost layer which is the epidermis. By removing the epidermis, the dermis can be inserted into the nose to augment the nose in Asian rhinoplasty.
The third material is Fat. Fat can be harvested from a syringe and injected back into the nose with a syringe or it can be taken with the dermis as a dermal fat graft.
In terms of the amount of resorption or the amount of removal or elimination of the graft is in the order of fat, dermis, and cartilage, fat is the most likely to be resorbed in Asian rhinoplasty.
Cartilage graft is least likely to be resorbed in Asian rhinoplasty.
Dr. Kenneth Kim, a board certified plastic surgeon, will go over in detail the benefit and complications of various autologous grafts in Asian rhinoplasty. Often a revision Asian rhinoplasty requires an autologous graft. However, even primary or the first time Asian rhinoplasty benefits from using all autologous tissue to augment the nose.
By carefully determining which material to use in the Asian rhinoplasty, a safe, long lasting, and most natural nose can be created in Asians.
