What are the potential side effects of excessive bone resection in facial contouring surgery?

 

hello. Dr. Hyun-woo Cho, Chief Director of 3D Plastic Surgery no see.

 

facial contouring surgery Among those who are considering... The more you trim, the prettier it looks. There are many cases where people think that.

 

But the bone Once deleted, it is difficult to restore It can also affect nerves, soft tissues, and sinuses, making recovery difficult.

In particular, there was a time in the past when extensive restraint was in vogue, aiming solely for dramatic changes.

Recently Rather, I consulted about revision surgery due to discomfort caused by excessive resection. There are also quite a few cases where it is received.

today Cheekbone reduction · Square jaw surgery · Chin surgery When the amount of bone resected is large

What problems might arise We will introduce key case studies.

 

 

For cheekbone reduction surgery, is it better to remove a lot of tissue?

📌 During cheekbone reduction surgery, excessive resection can lead to decreased sensation, nonunion, or sinus problems.

 

Cheekbone reduction surgery The bone is cut to reduce the “front cheekbone.”
At this time, after cutting the bone, The severed front and back bones must reattach to each other. do.

 

Cheekbone reduction surgery The area that is frequently resected is commonly called the '45° cheekbone line'.

Around here Nerve responsible for sensation around the eyes It is located here ( Blue circle in the picture below ),

In the past, a method of resecting this area along with the rest was often used.

In this case,
🔸 dullness of sensation around the eyes
🔸 Reduced distance of the back cheekbone → Nonunion (a condition where bones do not fuse well) generation
🔸 If the bone does not fuse properly, covering it The skin appears to be sagging as the foundation has weakened.
🔸 The sinuses are widely exposed Increased risk of sinusitis

Problems such as the following may occur.

 

Recently, the amount of cheekbone removal has been reduced Method of rotating backwards ( cheekbone rotation surgery : Simply put, it involves changing the direction of the cut bone and reattaching it. ) It is widely chosen in terms of safety and preference.

 

 

Square jaw surgery, 'Will my face look slimmer if I cut off as much as possible?'

📌 The most important thing in square jaw surgery is that the area below the nerve line is the safety baseline; removing more than that carries a risk of sensory damage.

 

Below the square jaw area In Nerve line responsible for sensation in the lower jaw (The red line in the figure below) passes by.
In a normal procedure, this nerve line (Red line) The safety standard is to perform the osteotomy with sufficient clearance below. no see.

The problem is,

Please make it look smaller.
Please cut off as much as possible.

With a request like that There were cases where the nerve line was resected up to the upper part. The point is.

 

 

The possible results in this case are as follows:

 

⚠️ Loss of sensation (may be permanent)
⚠️ Numbness around the lower lip and jaw: No sensation even when drooling or food spills
⚠️ Possibility of changes in mouth shape and decreased motor function

 

thus square jaw surgery silver Surgery where nerve protection takes precedence over the amount of tissue removed It is important to understand that point.

 

Chin Surgery: The Truth About 'Severe Reduction Makes the Face Slimmer?'

📌Chin surgery If the amount of resection increases Risk of nerve damage and bone resorption This can increase.

 

A standard chin osteotomy is performed below the nerve line (red line in the figure below).

 

(CT scan of chin surgery)

 

However, if the position where the bone is cut is raised to shorten the jaw length, like in square jaw surgery Effect on sensory nerves You can give.

 

 

Also, due to excessive restraint

🔸 Remaining bone surface area decreases
🔸 Cases where the bone is absorbed and the shape collapses afterwards
It is also observed.

 

 

in other words, If you look only at short-term results, it may look slimmer, but
As time goes by The opposite result, where the outline collapses, may occur. You should keep in mind that point.

FAQ 🙋‍♀️🙋‍♂️

Q1. What kind of facial contouring surgery should I get if my face looks wide?

 

A1. If the cheekbone line appears wide, consider the cheekbones and square jaw together. There are many cases where this happens.

From the side In cases where the jawline is long, a method of reducing the chin area as well. This is also utilized.
However, since the resection amount is determined based on the individual's skeletal range, an actual CT-based evaluation is required during the consultation.

 

Q2. Is it possible to request that the bone be shaved down to a desired amount during facial contouring surgery?

A2. Bone is not sculpted as freely as clay.

cheekbone thickness, nerve location, bone joint range, etc. Each has an average limit.
Therefore, the patient's goals and the actual possible scope of surgery may not be the same.

 

Q3. How long does the recovery period take for facial contouring surgery?

A3. Generally Significant swelling lasts for up to about two weeks. It generally subsides, but residual swelling may persist for a longer period.
The average recovery time is Gradual changes over several weeks You will expect a flow that goes through.

 

 

conclusion

facial contouring surgery It does not simply lead to “the more you delete, the better the result.”

 

✔ Excessive bone removal may result in sensory issues.
✔ Sagging, absorption, or nonunion may occur after recovery.
✔ More than the removal range Preservation of a safe structure increases long-term satisfaction

 

 

Therefore, rather than “as much as possible” “Within face shape and safety range” Design the outline The approach of doing so is more suitable.

 

Before making a final decision, be sure to consult during the consultation, CT check, Nerve line location, Resectable range, Prediction results Please take the time to receive guidance on this together.
