Nose is the most three dimensional structure located on the central portion of the face. Therefore, the nasal shape is one of the most important factors on deciding upon one's impression. Hump-nose is characterized by nasal hump, acute tip angle, drooping or/and under-projection of tip, and broad nasal dorsum. Because of these characteristics, recently more patients with hump-nose are inclined to correct their problematic nose. The purpose of this study was to classify hump-nose according to hump size and provide proper operating methods in each group. From August 2003 to August 2005, in 46 cases, we classified the hump nose into three groups, small(group A; n=30), medium(group B; n=6), and large(group C; n=10) in accordance with size and location of hump and in each group we effectively corrected the hump with our proper operating methods. In the large group, one case of tension nose temporarily appeared but soon improved and we obtained satisfactory results in the other cases.
