Clinical manifestations of nasal deviation after augmentation rhinoplasty: nasal root deviation, nasal bridge axis deviation and nasal tip deviation. Causes of crooked nose after augmentation rhinoplasty: 1, wrong cavity level, too large cavity; Medical silica gel is incompatible with surrounding tissues, forming a fibrous capsule, which moves up and down under the action of gravity and external force. The deflection is mainly caused by the deflection of the cavity itself. 2. Preoperative deviation of nasal bone, nasal cartilage and nasal septum cartilage. 3. Because of the operation itself, such as the separation cavity is too small and not straight, the separation cavity is incomplete, and the thickness is uneven, the silicone prosthesis is not good at sculpture. 4, psychological factors will also be suitable for the nose "crooked", there is no absolute "positive", only the relative "positive". Under the psychological hint, sometimes people think that the nose is skewed to one side, so we should pay attention to this problem. How to avoid: 1. Communicate fully with the doctor before operation. As long as experienced doctors fully understand the nasal condition before operation, there will be no nasal deviation. 2. Pay attention within one month after operation to avoid external force hitting the nose.
