The hump nose, also known as the hunchback nose, is one of the more common external nasal deformities. In addition, nasal trauma can also cause this deformity. Hump nose is characterized by a hump-like elevation of the external nasal cartilage junction area, which can be treated surgically by entering through bilateral intranasal incisions or butterfly-shaped incisions, amputating the elevated “hump back” and chiseling and loosening the maxillary frontal process roots, squeezing them to the midline position, so that the broken ends of the nasal bone osteotomies on both sides can be reunited. The specific risks are as follows: 1, bleeding: there is a risk of bleeding during the surgery, the hump nose correction bleeding is mainly manifested as bleeding from the incision or nasal septum hematoma, for the nasal septum hematoma should be extracted or cleaned up the surgical trauma in time to drain out the blood, otherwise, it is easy to secondary infection, destruction of cartilage, leading to septal abscess; 2, infection: septal abscess may occur, or even incisional infection, which can be a serious case of 3, over-correction or under-correction: the degree of correction of the hump nose in the surgery. If a lot of correction, it may lead to saddle nose deformity, while less correction may not achieve the desired cosmetic effect; 4, other: scar contracture nostril asymmetry, the bridge of the nose is not straight.
