Rhinoplasty is similar to the principle of buried wire surgery, which makes the shape of the nose lifted and appear more upright, and its maintenance time is usually 1-2 years, depending on the surgical wire and post-operative care methods. Rhinoplasty is a more popular way of rhinoplasty in recent years, the material used is absorbable thread, the effect can be maintained for about 1-2 years, some of the threads are maintained for a longer time, while some of the threads are short-lived and can be absorbed within 1 year. In addition, the maintenance time of rhinoplasty is also related to postoperative care. Early local care and systemic anti-infection treatment to avoid skin infection can delay the maintenance time of rhinoplasty effect. In addition, patients need to pay attention to avoid water at the needle holes within 1 week after surgery, apply erythromycin eye ointment to the needle holes, apply cold packs, take 3-5 days of oral anti-inflammatory drugs, avoid smoking and alcohol, and prohibit eating seafood and other foods.
