Various methods and materials have been used for nasal augmentation. Silicone implanst for nasal augmentation has now been used most populary, but many complications after silicon implantations have been arised. Many complications after silicone implantation for nasal augmentation are followings : 
1) Infection.
2) Thinning of the skin and translucency of the skin.
3) Visible implant.
4) Discoloration and miliary form eruption of the nose.
5) Extrusion of the implant.
6) Deviation of the implant.
7) Movable implant.
8) Granuloma due to calcification around the implant.
  Dermofat is an autogenous material that could be effectively used in nasal augmentation. Over the past 17 years, I performed about 3000 cases of the dermofat grafts for primary and secondary nasal augmentation. Out of the 3000 cases, about 300 cases were secondary augmentation rhinoplasty for treatment of complications after silicone implantation or foreign body injection of the nose.
The dermofat grafts in primary nasal augmentation and secondary nasal augmentation after the removal of foreign materials have the following results:
 1) Dermofat graft can be safely applied in cases of the complicated noses after bone graft, cartilage graft, free fat graft or silastic implantation for nasal depression.
 2) In a severe case of the saddle nose deformity, it can be done as the secondary augmentation for the more height after primary augmentation.
 3) It can be also partially augmented for the depression such as supratip depression, the deformity after removal of the mild hump and the deviated nose.
 4) The deviation after the augmented nose using dermofat graft can be easily correctable with Triamcinolone injections.
 5) The donor site of the dermofat graft I performed is the potion between the anus and coccyx. The area has more compact fat and thicker dermis than other parts of the body such as abdomen, inguinal area or gluteal fold.
