Hyaluronic acid rhinoplasty is a cosmetic procedure. It is a method of injecting hyaluronic acid to achieve the effect of rhinoplasty. As the “least likely to fail” micropigmentation, hyaluronic acid has a bunch of risks! Early post-injection complications: 1, postoperative pain, local redness, swelling and bruising. These symptoms usually disappear within 7 days, in addition to improving the injection technology, avoid taking anticoagulant and vasodilator drugs 2 weeks before surgery, cold compresses before and after surgery, can reduce the occurrence of complications. 2, the injection site appears nodules and hard lumps First of all, to clarify the nature of the injection, if the sodium hyaluronate gel, the general hard lumps about three days of natural softening. 3, injection site itching This can be caused by the disinfectant, but also may be allergic to injections. 4, hyperpigmentation This may be the physician injection skills are poor, the injection is too shallow. Doctors advise the candidate to protect the injection site from the sun or use laser treatment. 5, injection site infection This usually occurs 72 hours or more after the operation, can be seen under the epidermis with pus point formation, which is mostly related to the pre-surgery disinfection is not complete, or immediately after the operation make-up, water and other improper care and bacterial infection. Long-term complications: 1, excessive filling The highest incidence of tear trough area, because the filler site of the shallow depression, thin skin texture, and injection with a certain degree of resistance, improper force is very easy to appear local rice-like protrusion. If it cannot be smoothed out after massage, hyaluronidase should be applied to dissolve it. Secondly, for the root of the nose, if the injection is excessive, the root of the nose can be widened, the frontal nasal angle disappears and affects the appearance. If it is clear that the filler is sodium hyaluronate, hyaluronidase can be applied to dissolve it; if the injected material cannot be clarified, it can be observed for 4-6 months, and if the injected material has not been absorbed, then it can be removed by surgery. 2, injection absorption and displacement Mostly occurs in the temporal, nasal or buccal area. The frontal and temporal parts are usually injected at the loose level under the superficial temporal fascia, and when the injected volume is large, the injected material will be easily displaced due to the effect of gravity, which should be taken seriously. 3, periodic redness and swelling in the injection area Redness and swelling occur regularly in the injection area, with an interval of 2 weeks or 1 month for 1 episode. Part of the candidates after antibiotic treatment, can be improved; there are candidates on the treatment is ineffective, but after the cycle can naturally subside, and the cycle of seizures recur again. 4, injection site chronic granuloma This type of complication is rare, foreign literature has been reported, there are also cases of formation of pseudo-encapsulation. For patients with unknown injections, hormonal therapy can be considered. 5, injection site acne or erythema mostly occurs when the injection dose is high and the injection level is shallow, the local skin is in a tight, shiny state, erythema can last for months. Preventive measures: Do not overdo the single-point injection, so as not to affect the metabolism of the skin. 6, vascular compression or embolism Mostly occurs in the brow lines, nasolabial folds, the tip of the nose at the hyaluronic acid injection. Because these parts of the blood vessels are rich, and with the ophthalmic artery, nasal dorsal artery and other end-feeding small arteries have a wide range of traffic branches, injection is easy to cause direct vascular embolism, can lead to blindness, tip of the nose, necrosis, partial necrosis of the upper lip. If embolism does not occur, because the local injection volume is too large can cause vascular compression, can also cause a certain degree of ischemia, necrosis performance. Micro plastic surgery before you look at the qualifications 1, look at the hospital qualifications Plastic surgery hospitals must have a “medical institution practice permit” and business license. The program shown on the certificate should have medical cosmetic subjects such as “medical cosmetology” and “cosmetic surgery”.
