Hump nose is a congenital deformity, which means that the nose is long, large and high, and the middle bone of the nose protrudes, forming a shape like a mountain peak or a hump-like bump. Most of the hump noses are due to congenital causes, local tissue overgrowth during nasal development, or occasionally due to distorted healing of nasal bone trauma or late bone scab growth. Except for the morphological abnormality, there is no functional disorder and it does not affect the sense of smell, pronunciation and respiratory function. The humped nose is more common in the Western population. In Eastern populations, the majority of humped noses are characterized by a mildly elevated dorsal aspect of the nose. When the hump is so pronounced that it interferes with the harmony of the nose with other facial organs, it can be corrected by hump rhinoplasty. The purpose of hump rhinoplasty is to make the hump smaller through surgery, especially to remove the hump so that the nasal dorsum is straight from the side view. Patients with humped nose caused by trauma can be corrected surgically according to specific nasal features. Specifically, for patients with frontal nasal angle within the standard range and nasofacial angle within 30°, most of them are caused by deviation of nasal tip development and can be corrected by double segmental rib cartilage rhinoplasty. For patients with a well-developed nasal tip, a normal nasofacial angle, and a wide nasal dorsum, they can be restored by means of osteotomy and bone grinding.
