Rhinoplasty is now the most important among rhinoplasty and rhinoplasty is an important step. It is a comprehensive procedure that is performed to change the height and shape of the nose by implanting appropriate materials to improve the appearance of a collapsed nose, crooked nose, traumatic nose, skyward nose, humped nose, etc. The following are the frequently asked questions about rhinoplasty.
I. What kinds of rhinoplasty materials are commonly used nowadays?
Nowadays, rhinoplasty materials should be divided into two categories: autologous materials and artificial materials. Autologous materials include autologous cartilage, autologous bone, autologous fat and autologous dermis. Artificial materials include silicone, tumescent, Medpor, hyaluronic acid, etc. These materials have their own advantages and disadvantages when applied to rhinoplasty, so patients can choose according to their own situation.
Second, what are the advantages and disadvantages of autologous materials and artificial materials?
1.First of all, autologous materials need to be taken from oneself, which means additional surgical items and painful surgery are needed, and the technical conditions of the surgeon are more demanding. There is a possibility of partial absorption after surgery. In case of infection and dissatisfaction, it is difficult to remove the rhinoplasty material and more traumatic. But the autologous material can establish blood relationship with the body, often survive for a long time, no rejection, even if the trauma can heal by itself, there is no prosthesis rhinoplasty late due to the thinning of the skin outline sense.
2, the biggest advantage of artificial material is that no additional surgical damage is needed, and the prosthesis can reveal the ideal contour and will not be absorbed and deformed in the long term. However, the disadvantage is that it is easy to appear after the skin breakage is exposed and the contour of the prosthesis is revealed by the thinning of the skin in the late stage, that is, the appearance of translucent.
Third, what are the advantages and disadvantages of various autologous rhinoplasty materials?
1, autologous cartilage: if you want to augment the entire nasal bridge, nasal tip, we believe that the preferred autologous rib cartilage, it is sufficient, elastic, easy to sculpt, ischemic resistance, absorption less, in the comprehensive rhinoplasty application is comfortable, widely liked by nasal cosmetic plastic surgeons. The disadvantage is that it leaves a surgical incision scar at the edge of the rib arch (or the inframammary fold), which is approximately 2 to 3 cm in a skilled surgical operation. Young women may have serious problems with calcification of the rib cartilage, which affects sculpting. Then there is a little absorption and deformation in some patients after rib cartilage rhinoplasty, which affects the surgical result. To solve this problem, some doctors cut the cartilage into particles for transplantation for rhinoplasty. The amount of auricular cartilage or nasal septum cartilage is small, only used for nasal tip and nasal small column plastic surgery, and its small amount is not enough for comprehensive rhinoplasty or nasal root augmentation.
2, autologous bone: first of all, autologous bone is slightly more complicated to take, bone sculpture is difficult, later absorbed more, or even completely absorbed. Application is less.
3, autologous fat: now the application is more. It is more convenient to take material and inject, and does not leave traces, but it is more absorbed later, not easy to shape, and requires multiple operations. So it is mostly used for patients with short nasal deformity that is not obvious, or the supplement of insufficient autologous rib cartilage rhinoplasty.
4.Dermis: In fact, it should be dermis fat flap rhinoplasty, which can be taken in hidden parts of the body and the traces are not obvious. However, there are also difficulties in shaping, the three-dimensional sense is not strong, and there is also partial absorption at a later stage, and there may also be a serious problem if the nose is fat and bloated at the same time after the body is obese at a later stage. If combined with auricular cartilage nose tip, dermal fat flap nose bridge and nasal root, it is still a good choice.
Fourth, what are the advantages and disadvantages of various artificial materials for rhinoplasty?
1, silicone: the most commonly used and most affordable rhinoplasty material. It is used in the body implants for many years, safe and effective, stable in the body, easy to sculpt and shape. The disadvantage is that when the rhinoplasty is too exaggerated, the skin at the tip of the nose is prone to break down, the prosthesis is exposed and can only be removed, leaving a scar at the tip of the nose, which affects the surgery again. Silicone prosthesis at a later stage, especially after the over-exaggerated rhinoplasty, the skin will become thin and translucent, revealing the contours of the prosthesis, giving a sense of surgical sculpture, not natural enough.
2, tumescent: now commonly used another prosthetic material is tumescent, also called porous polytetrafluoroethylene. It has been widely used in heart valves and other implants, safe and effective, stable in the body. Because it is porous material, easier to bend and shape, but also facilitate the tissue in the surface fit, early prosthesis shrinkage phenomenon, while in the late emergence of prosthetic contour sense phenomenon is less. This material is more expensive and requires higher surgical aseptic details, otherwise there is the possibility of infection after surgery.
3, Medpor material: is porous polyethylene, hard texture, mostly used for soft tissue rich parts of the filling. Rhinoplasty is easy to appear exposed and less used.
4.Sodium hyaluronate (hyaluronic acid), as an injectable rhinoplasty material, is easy to operate, with little damage and quick recovery, and there is basically no obvious trace on the second or third day. However, it can only last for 6-10 months, and if the amount of injection is large, the nose will not be straight enough and appear bloated and rounded. Therefore, it is mostly used for patients whose nasal deformity is not obvious, or patients who are worried about the trauma of surgery.
V. What are the precautions for rhinoplasty?
Patients preparing for rhinoplasty should be healthy and have no underlying diseases, do not have symptoms such as cold and runny nose, and female patients should avoid menstruation. The swelling will be obvious in the first two days after the conventional rhinoplasty, and there will be some bruises on the periorbital loose tissue, and the swelling will start to decrease after the third day, and the swelling will subside in about 7-10 days, and the facial bruises will be basically absorbed completely. After 2-3 months after the surgery, a stable nose shape is achieved. In case of autologous tissue rhinoplasty, the recovery time is similar to that of prosthesis, but the final stable effect will be obtained only after 3-6 months.
VI. If rhinoplasty fails, when would be a better time to remove it? What are the reasons for failure? Can the implant be re-implanted immediately while removing it?
The most common cases of unsatisfactory rhinoplasty are crooked and over exaggerated in the early stage, and failures such as exposed prosthesis and overly obvious sense of contour in the later stage. The main reason is the sculpting of the prosthesis and the problems of the surgical peeling level and cavity. If these situations occur, it can be removed as soon as possible, there is no clear time limit.
Generally speaking, the implant can be reinserted at the same time as it is removed. However, in patients with thin skin and pronounced implant contours or skin breakdown, it will take 3 months before the implant can be removed and re-implanted. If the skin is too thin, you can remove the prosthesis and use autologous rib cartilage to re-augment the nose and rhinoplasty.
7. Can the tip of the nose be injected? Why?
Hyaluronic acid can be injected into the tip of the nose to lengthen the height, but it requires a certain injection technique and the amount of increase is limited. It should be injected both subcutaneously at the tip of the nose and also at the base of the nasal columella in order to achieve satisfactory results. Nasal tip injection may appear as widening of the nose, mainly due to excessive injection or injection between the cartilage of the medial foot of the nose.
Eight, are all incisions of nasal surgery internal incisions? What are the external incisions?
Nasal surgery is basically an internal nostril incision, but most doctors use a bird-like incision during comprehensive rhinoplasty, that is, a bilateral nostril incision and a transverse incision below the nasal column, and the traces are not obvious after healing. Some doctors only use bilateral nostril incisions, but the operation is a little more complicated.
Nine, silicone, tumescent and other materials generally have a shelf life, so do I need to replace them regularly?
Now silicone, tumescent are solid materials, chemically stable, thoroughly disinfected and sterilized after packaging. The so-called shelf life is this sterile packaging to ensure the sterility of the time, during which you can be implanted directly into the body during surgery. Even after the shelf life has passed, sterilization allows implantation. If the prosthesis is implanted in the body then it can be permanently effective and will not react with the body and does not need to be replaced regularly.
X. What are the symptoms of nasal infection that we usually talk about? How can I avoid it?
The nasal infection we are talking about is the result of poor asepsis during surgery or after the skin breaks down. The symptoms are redness and swelling of the skin of the nose, pain, and secretion inside the incision or rupture.
Therefore, it is necessary to go to a qualified hospital to see a qualified doctor for rhinoplasty, to operate strictly aseptically during the surgery, and to clean the incision with iodophor or hydrogen peroxide two to three times a day after the surgery. If the prosthesis is exposed, take it out as soon as possible. If there is redness, swelling and pain in the nose, consult a doctor in time, apply antibacterial agents, or even take out the prosthesis.
