A natural and refined nasal tip ~
What is AlloDerm (SureDerm) surgery for rhinoplasty?
�
There are various ways to raise the nose, such as silicone or Gore-Tex.
When using AlloDerm (SureDerm) to raise the nose, it is mainly applied to the nasal tip rather than the bridge.
It is used when you want to add volume to the nasal tip, or when you want to lengthen the tip,
or when you want to create a refined nasal tip like an upturned nose.
AlloDerm is a material made by processing human skin, also called SureDerm. It is a biomaterial from which antigens have been removed during processing so that it can be transplanted to anyone.
It can produce an effect similar to grafting one's own dermis, and because antigens that cause rejection through antigen-antibody reactions have been removed, the procedure can be performed without side effects such as rejection.
It has the advantage of enabling convenient nasal tip surgery without the burden and inconvenience of having to harvest cartilage, which is the biggest drawback of autologous cartilage grafting.
It is officially imported and used with approval from the U.S. Food and Drug Administration, and there are also domestically produced versions.
Imported products are called AlloDerm, and domestic products are called SureDerm, with almost no difference in effect.
Why use AlloDerm (SureDerm) instead of cartilage for nasal tip surgery?
The reason AlloDerm (SureDerm) is used instead of cartilage for nasal tip surgery is that cartilage grafting is more complex, requires harvesting cartilage, and is costly.
Because AlloDerm (SureDerm) must also become established like a cartilage graft, it has the advantage of having no side effects, similar results to cartilage grafting, a simpler procedure, and lower cost.
In other words, it is because the effect and safety are similar to cartilage, while the cost is lower and the surgery is simpler.
What is the manufacturing process for AlloDerm (SureDerm)?
| ① Skin is donated by a donor. |
|---|
| ② The skin is safety-tested and stored at a skin bank. |
| ③ The manufacturer receives the skin and begins the production process. |
| ④ The epidermis is removed from the skin. |
| ⑤ Antigens are removed through cell removal. |
| ⑥ It is freeze-dried, sterilized, and packaged. |
What are the indications for rhinoplasty using AlloDerm (SureDerm)?
★ When the nasal tip is small or low
★ When the nasal tip is upturned or short
★ When there is a depression between the bridge and the nasal tip
★ When additional augmentation of the nasal tip is desired after inserting an implant such as silicone
What is the surgical process for rhinoplasty using AlloDerm (SureDerm)?
The reason the cartilage is gathered and tied is to allow the cartilage to serve as support for the AlloDerm (SureDerm).
Check whether AlloDerm (SureDerm) has been placed accurately in the correct position.
Examples of AlloDerm (SureDerm) use in rhinoplasty
How is AlloDerm (SureDerm) applied in rhinoplasty?
The AlloDerm (SureDerm) procedure for the nose is not suitable for everyone.
The alar cartilage must be developed to a certain extent.
If the nasal cartilage is not sufficiently developed, grafting AlloDerm will only cause the cartilage to be compressed, so the effectiveness of the procedure will be reduced.
It is a suitable surgery when the cartilage is somewhat developed and the nasal tip is upturned or short.
What are the advantages of rhinoplasty using AlloDerm (SureDerm)?
① The surgery is simple and less expensive than cartilage grafting.
② It is effective for slightly raising or extending the nasal tip.
③ No tape fixation is needed after surgery, so you can return to daily life immediately.
④ Because it is a biomaterial, side effects such as inflammation are rarely seen.
⑤ It is effective for correcting curved areas of the nose.
⑥ If additional augmentation is desired in the future, further grafting of artificial dermis is possible.
What are the immediate effects and the recovery process after rhinoplasty using AlloDerm (SureDerm)?
Immediately after the procedure, the nasal tip becomes more refined and then gradually settles down.
Because there is little swelling or bruising, you can return to daily life right away.
As it continues to settle over 3 to 6 months and fully integrates, the final appearance is reached when there are no further changes.
What should be noted when having rhinoplasty using AlloDerm (SureDerm)?
It can create an upturned nose or add length, but the procedure has limitations.
It should be applied when the cartilage is developed and the skin is flexible.
Otherwise, the effect of the procedure may be reduced, so the indications should be carefully assessed before performing it.

| Disadvantages | The volume may decrease over time due to graft survival rate. | - Because cartilage is hard, a visible boundary may form in the augmented area. - If the shape is unsatisfactory, removal is difficult. - Damage at the cartilage harvest site. - High cost. | - Inflammation may occur due to a foreign-body reaction. - Side effects such as skin discoloration or necrosis may occur due to blockage of nasal skin blood vessels. - If side effects occur, removal is almost difficult. |
