Normal human nose can be divided into high, medium and low nasal bridge.

In addition to the saddle nose, there are also a considerable part of people with low or medium nasal bridge in our country, which can improve their appearance and increase their beauty through rhinoplasty. Saddle nose and low nose bridge are the absolute indications for rhinoplasty, while medium nose bridge is the relative indications for rhinoplasty, which should be paid attention to and distinguished in clinical practice. Rhinoplasty must be in line with national conditions, and the surgical plan should be designed with reference to our national standard nasal aesthetic parameters, and full communication and consensus should be reached with patients before surgery to avoid future disputes.
