1. When augmentation rhinoplasty is performed, part or all of the medial foot or dome of alar cartilage is removed during nose separation, so that one side scar is healed, resulting in asymmetry of both alar nostrils.
2. The prosthesis on the alar cartilage dome is deviated, and the stress on the alar cartilage on both sides is unbalanced. The alar cartilage on the side with high pressure is low, which leads to asymmetry of alar nostrils on both sides.
3. The columella of L-shaped silicone prosthesis is not placed in the middle of the medial foot of alar cartilage, which leads to asymmetry of alar nostril on both sides.
Especially in augmentation rhinoplasty, if the nasal incision suture is not balanced or the wound site is swollen, there will be different sizes of nostrils visually, but this phenomenon is temporary and will disappear after the incision heals and the nose is swollen. This is when we often need to understand the asymmetry of nostrils. Many beauty seekers will ask this question after a few days of rhinoplasty. What they can do in swelling stage is not to be too nervous, and pay attention to postoperative care and hygiene of nostrils.
