Chin Implant Complications

The complications from a chin implant will vary depending on the type of implant used. Various substances are currently used for chin implants including solid silicone, ePTFE (tradename Goretex), linear high-density polyethylene (tradename Medpor), the patient's own fat, and others.

During the implant procedure, there will be some bleeding and bleeding is possible for several days after surgery. Generally, this bleeding is not life threatening and does not come near requiring blood transfusions.

There is a nerve which provides sensation for the lower lip, lower face, and chin area which comes out of the lower jaw bone on either side just off the midline. This nerve can be bruised and stretched during surgery and, rarely, permanently damaged. This can create a temporary or possibly permanent numbness of the lower lip, lower face, and chin area. This does not in any way affect the movement of the lip but can cause some problems with drinking liquids due to lip numbness, much the same experience as after having injections at the dentist.

Infection is always a risk. If an implant is placed other than fat, infection may require implant removal. Often this can be avoided with prompt antibiotic treatment.

There is always a possibility of implant movement. This usually can be handled with conservative measures, though removal of the implant is possible.

Any implants will show some resorption of the bottom jaw bone over time. This is usually not a problem and can only be seen on x-ray. In people with very thin jaw bones this resorption can lead to breakage of the bone which would require repair but this is a rare complication.

As with any surgical procedure, other risks may pertain to your specific situation given other medical conditions. It is imperative to speak with a knowledgeable surgeon before undertaking any surgical procedures and disclose all of your medical conditions.

As with any plastic surgery procedure, there are risks of infection and bleeding associated with having a chin implant. Fortunately, both of these are quite rare, especially if the implant is placed from under the chin where a sterile environment can be maintained during placement of the implant (as opposed to going through the mouth to place the implant).

In addition, there are risks of possible nerve and muscle damage from the chin implant. There are both sensory (sensation) nerves and motor (movement) nerves around the jaw that can be inadvertently injured during the procedure. Sometimes the muscle can also be affected from the implant, causing abnormal movement of the lower lip with a change in pattern of speech.

There is also a chance that the implant can cause absorption of the underlying jaw bone, which takes away from the desired effect of providing an augmented appearance. Finally, you may simply not like the appearance of your lower face following the chin implant procedure. Fortunately, a majority of patients undergoing this type of procedure end up fairly happy with their results with minimal complications.

Possible complications that patients need to be aware of before surgery include:

• Infection
• Bleeding
• Nerve damage
• Mandible bony absorption (a small layer of bone fades away)
• Rejection of the implant
• Lip dysfunction
• Movement of the implant

Experience, experience, experience.

Anyone can have complications from chin implant surgery or chin augmentation surgery. Augmentation with implants are as follows:

1.  Numbness of the lower lip either on one side or both sides. In the literature it stated that this happens anywhere from 3% to 10% of the time. However, in most experienced surgeons practices long-term numbness should be less than 3%. When it does occur is most often temporary and can last weeks to months. The approach you take for surgery, external incision versus intraoral incision, can affect this. The risks are higher with the intraoral approach.

2.  Infection from implant placement is very rare especially when using an external incision just under the chin. If an infection results it can show itself within a week to even several weeks. It typically comes in the form of increasing pain not decreasing pain, redness, warmth, or new onset of lower lip numbness when there was none before.

3. Under correction or overcorrection. This is simply dealt with by replacing the implant or augmenting under correction with some filler or fat transfer.

4. Visible incision under the chin. I operate on Asian, African-American, and Mediterranean patients all the time and I most frequently use incision underneath the chin because I like its low complication profile. It is possible that the incision, he will and require some revision several weeks from now but I've never had to do it. I have revised incisions from overseas and most of those cases were instances where external sutures were left just too long. There are special techniques for closure that makes this possibility very remote.

Chin augmentations with implants are subject to the usual surgical potential dangers: infection, hematoma, seroma, and malpositioning.  Then there are specific dangers such as erosion of the mandible, assymetric prolapse of one side of the implant below the mandible which can be both visible and palpable.  Sensory loss to the lip and/or sensory or motor damage to the muscles that surround the lip are also possible.

The most common complication is malpositioning and this can be eliminated by placing titanium screws through the implant into the mandible.  This stabilization also decreases post operative swelling and speeds recovery.  I place all my implants in through the mouth; this leaves no visible scar and I've done several hundred without any sign of infection. 

My collegues have listed just about every possible complication that I can think of with chin implants, but remember that a silicone chin implant can usually be easily removed if it is not the look that you want as a minor office procedure. Some of the other materials, including your own fat, not so easy to remodel or remove.

Complications can depend on the type of material used, but I will concentrate on the standard Goretex and silastic implants and name a few:

Possible complications:

extrusion - implant making its way out

infection - usually requires removal

mobility - too mobile due to the receiving pocket being made too large

nerve / sensation problems - implant can possible impinge on the mental nerve

aesthetic - patient doesn't like the fundamental appearance change afforded by the implant

bony resorption - resorption of bone under the central aspect of the implant

Chin implants are a great proceedure with few complications. I place my chins with an external approach and have had maybe 1 or 2 infections in over a 1000 implant placements. Placed externally it is easy to get the proper positioning and stabilization through accurate pocket development and the occasional suture placement. A standard chin placement in our office is done under local anesthesia and takes 15 minutes to do.

• Too small
• Too big
• Infection
• Bleeding
• Interference with muscles of the lower lip
• Feeling the edge of the implant
• Choosing the wrong size and shape of implants

A chin implant is a very simple device and the associated risks are straight forward: A chin implant can be placed into position either by an incision under the chin or through the mouth. With the external approach, there will be a visible scar (which is generally very hard to see). With either approach, there is a risk of an infection and the risk is higher when using the oral route. If the implant gets infected, it will need to be removed to clear the infection. The implant is placed along the jawbone and could potentially squeeze a sensory nerve that provides sensation to the lower lip and chin. There is a very small chance this nerve could be cut during surgery, but more often the nerve gets compressed and this results in altered sensation. The device may not lay smoothly along the jawbone, and might be palpable or visibly asymmetric. Finally, you might end up with more projection than what you wish. Most of these risks are true with any surgical operation and many are reversible by implant removal - speak with your surgeon to discuss any further concerns.
