As one of the common procedures in the medical cosmetic industry, patients suitable for rhinoplasty mainly include the following categories: 1, people with congenitally low nasal bridge, i.e. patients with saddle nose, judged by whether the height of the nasal bridge is at the level of the eye; 2, patients with nasal tip, nasal wing and nasal column dysplasia resulting in nasal morphology not meeting aesthetic requirements; 3, patients with congenital cleft lip and palate with nose deformity due to correction or complications; 4, trauma-induced collapse of the nasal bridge and other traumatic deformities of the nose.
