Side effects of chin augmentation surgery failure? Common reasons for chin augmentation revision surgery?

Chin Augmentation — Often, people who want to adjust their chin implants after surgery do so because they are dissatisfied with the appearance of their chin. This can be addressed by changing the shape and position of the implant.

在二次手術的時候，通常來說第一次手術不會影響到，除非有做過Genioplasty、削骨手術、曾有感染過或是微整醫美注射過多等等較複雜的情況。

Common reasons for chin reconstruction:

⁉ Chin displacement:

Vertical or horizontal skewed positioning

每天吃飯、說話、做表情甚至磨牙的時候，都會使用到下巴的肌肉，因此植入物是有可能因為動作影響而位移的，此外還有受到外界大力撞擊而產生的位移，或是也有可能墊下巴的植入物不符合下巴形狀、與原本不夠貼合等原因，使植入物產生了上下、左右的歪斜跑位，而這也是許多人在Chin Augmentation前最擔心的一點。

⁉Subjective dislike of shape or implant:

After the surgery, you may not be satisfied with the implanted material or shape. In terms of shape, it may be sharper or blunter than expected, or you may feel that the shape has changed too much and you are not used to it; or the change is so small that you can't even tell that you have had surgery. These are all possible.

In addition, implants, each material has its own shape, and their appearance may change after implantation. It is possible that after being placed in the chin, it is different from what you expected, or you are not used to the feel, etc., so you want to change the implant material.

Therefore, it is necessary to have a detailed discussion with the doctor before the surgery, because aesthetics may change over time. For example, a more pointed chin shape is popular at certain times, while at other times, people change their aesthetic preferences and feel that a more rounded chin shape looks more approachable. It is also very important to confirm what you need and what suits you before the surgery.

⁉Postoperative infection: Must be removed

During chin surgery, care must be taken to avoid damaging the inferior alveolar nerve, which could lead to numbness in the lower lip or chin. Also, care must be taken to avoid damaging the mentalis muscle, as severing it could make it difficult for the lips to close, causing weakness and drooping, resulting in an unnatural mouth shape. Other surgical infections could cause wound infection, inflammation, poor wound healing, hematoma, bruising, or implant rejection. In such cases, depending on the infection situation, the implant must be removed first to allow the inflamed wound to heal properly.

What are the common risks and complications associated with chin implantation?

!Infect

據文獻報導，Chin Augmentation感染率約為0.6%~0.7%之間，手術中的無菌操作非常重要，另外可以搭配負壓灌注抗生素進入植入物的結構孔洞內，使植入物本身就能抗菌，若是發生感染情況，只需沿著原來的切口取出植入物，再搭配適當的抗生素治療即可。

‼ Scar contracture

Scar contracture is a common problem in chin reconstruction. Excessive scar tissue can cause depressions or unevenness in the appearance of the chin. If too much Radiesse or hyaluronic acid is injected, there may also be excessive scar tissue inside the chin. If a surgical implant is subsequently used for the chin, scar tissue is more likely to form.

‼ Mental nerve damage

The mental nerve is responsible for sensation in the skin of the chin and lower lip. If the procedure is performed according to standard and professional procedures, it will usually not be damaged. However, if a large implant is placed, or if the jawbone is really too small, the mental nerve may be compressed by the implant during the operation. Therefore, the use of bone screws can reduce the occurrence of this situation.

Bone erosion caused by implants

In the past, some chin implants made of silicone have been found to be eroded. In such cases, the bone usually regenerates and recovers after the implant is removed.

‼ Object placement offset

Because the chin is an area that is used every day, there is a risk that the implant may shift out of place. If bone screws are used for solid fixation, this problem is less likely to occur and the implant will be more stable and secure.

Dissatisfied with chin shape?

Too wide, too narrow, too upturned, too crooked, or the shape doesn't match your expectations… These are probably the most common problems people encounter. It's crucial to have a thorough consultation with your doctor before surgery and refer to their past cases to understand their aesthetic sense. If you want to change the shape after surgery, you can wait until the swelling has completely subsided. If you're still not satisfied, you can have another surgery to remove the previous implant and reshape it. If you don't want another surgery and only need minor adjustments, you can have hyaluronic acid or autologous fat injected locally.

Chin reconstruction surgery case

The nose and chin in the picture above were deformed due to excessive injection of Radiesse. The surgery was performed to remove the Radiesse and place an artificial bone chin.
