In oriental , the materials using for nasal augmentation were usually silicone implants. But recently autogenous material such as dermofat, fascia, cartilage and even bone were also used for the augmentation of nose due to its successful results especially in severe saddle nose deformity owing to congenital or acquired reasons.
 For the past 10 years (1988-1998), 201 cases of nasal augmentations by using outer table calvarial bone graft were performed, on nasal dorsum (160 cases), depressed paranasal area (39 cases), and columellar struts(2cases). The incidence for bone grafting were almost even between congenital and acquired reasons in which complicated silicone augmentation rhinoplasty cases took majority. The graft harvest was done through coronal or limited coronal incision in the non-dominant parietal  area. The body defect after graft harvest was filled with bone dust and bone chips collected during bony harvesting, and covered with Surgicel. The graft are approximately 1.0 to 1.25cm in width, their length is that of the desired nasal length (usually 5 to 6cm), and the numbers of graft were 1 to 3 layers as necessary. The fixations of graft was done by miniscrews in early case, and is now usually done by one or two microscrews and the length of the screws was usuallly 6mm.
 Based on the 1 to 10 years (average; 6.5 years) of follow-up, bony consolidation of the grafted calvarial bone to the original nasal bone was noticed in almost all cases without significant bony absorptions. 
 The complications of scalp were dural exposure in early 2cases due to unskillfuled technique, hematomas were in 3 cases, removed with aspiration, but no evidence of infection was noticed in any cases. The complications of nose were few. In almost cases, initially sharply tensed nasal tips were spontaneously remodeled in time, only in 3 cases became exposed nasal tip which was rongeured off in the office without anesthesia. Fractures of grafted bone in 3 cases were uneventually treated by closed reduction. Displaced bone graft in 1 case was corrected by corrective rhinoplasty, and palpable head of screws using bone fixations in early period were removed under local anesthesia without special problem.
 The calvarial bone graft is less absorbable and resistrant to infection and external  forces compared to other bone graft (iliac or rib bone) and maintain its unique curvature which is well harmonized with facial contour without special complications. So, outer table calvarial bone graft for nasal augmentation is excellent method for correction of congenital and acquired deformity.
