MACS Facial Bone Revision Case Study

CASE 1.
Insufficient Results from Previous Jaw & Chin Surgery
Despite undergoing a 'Triple Facial Contouring' procedure at another clinic, the patient experienced minimal aesthetic improvement.
MACS subsequently performed a combination of Orthognathic (Double Jaw) surgery and Revision Facial Contouring.
- Before
- After
MACS Solution

Following the revision surgery, both the chin length and mandibular angle were effectively reduced, achieving the slender and refined facial line the patient desired.

CASE 2.
Persistent Underbite and Long Face Syndrome
The patient visited MACS seeking aesthetic improvement,
as their previous surgery failed to sufficiently correct the underbite and long facial structure.
- Before
- After
MACS Solution

To address both the underbite and long face, MACS performed a combination of Orthognathic (Double Jaw) surgery and Revision Facial Contouring. This effectively reduced the overall facial length, resulting in a more youthful and balanced facial line.

MACS Signature
Patient-Specific Anatomical Implant Reconstruction
MACS Signature Reconstruction is designed for cases where previous facial bone surgery resulted in
excessive resection or severe 'secondary angles.' By inserting custom-made implants—precisely fabricated based on CT data to
match each individual's unique anatomical structure—we restore a smooth, natural-looking volume to the face.

Over-resected mandibular angle resulting in an unnatural 'dog-jaw' appearance.

Flat, flattened cheekbones
with a loss of volume.

A blunt or overly resected chin
that looks unnatural even after surgery.

Titanium
·Biocompatible material with excellent osseointegration (bone-to-implant fusion).

·High strength and superior corrosion resistance, ideal for structural bone reconstruction.

·Proven safety and reliability backed by extensive clinical history and research.

PEEK
·A lightweight, high-strength implant material.

·Highly biocompatible, ensuring excellent integration with the body.

·Easily customizable for superior functional and aesthetic enhancement.

PCL+β-TCP
·FDA-approved biodegradable implant.

·The mesh-like structure promotes and guides natural bone regeneration.

·1:1 customized 3D printing for optimal functional and aesthetic results.

MACS Implant Reconstruction Case Study

CASE.
Excessively Resected Jawline and Sunken Cheekbones
The patient sought treatment at MACS due to an irregular,
over-resected jawline and a lack of cheekbone volume following a previous facial
contouring surgery performed at another clinic.
- Before
- After
Macs Solution

By utilizing 3D CT data to fabricate patient-specific titanium implants,
MACS performed a comprehensive reconstruction of the cheekbones and jawline.
This procedure restored a smooth, balanced, and naturally volumized facial contour.

Why is Facial Bone Revision Surgery So Difficult and Complex?

Issue 1. Complex Surgical Planning
Identifying the flaws of the previous surgery and creating a comprehensive new plan requires extreme technical precision and strategic insight.

Issue 2. Requirement for Meticulous Dissection
Soft tissues that have previously healed often become hardened or scarred. This necessitates even more delicate dissection techniques to minimize trauma.

Issue 3. Bone Osteotomy Challenges
We must accurately assess where previous bone cuts were made. Formulating a new osteotomy plan is highly complex, as it must account for bone density and previous fusion sites.

Issue 4. Difficulties in Re-fixation
Areas where plates were previously fixed often cannot accommodate new pins in the same spots. Surgical plans must meticulously account for these structural limitations to ensure stable fixation.

Issue 5. Suturing and Healing
Existing scar tissue at previous incision and suture sites can complicate the re-incision and recovery process during revision surgery.

Issue 6. Prolonged Recovery Period
Bone and surrounding tissues that have undergone multiple procedures require significant time to regenerate and heal. Consequently, the recovery process for revision surgery is often longer than the initial one.

Q.
Does facial bone revision surgery require a longer recovery period than the initial procedure?

A revision procedure does not necessarily mean a longer recovery time. However, because the previous surgery may have altered the anatomical positions of facial bones, muscles, and nerves, sutured areas can be more prone to opening or may not heal as easily. Therefore, a more meticulous and cautious approach is required during revision surgery to ensure optimal healing.

Q.
Does double jaw revision surgery require orthodontic treatment again?

It is not always mandatory to undergo orthodontic treatment alongside the revision. If your occlusion (bite) is normal after the initial surgery, the revision can be performed while maintaining your current bite as much as possible. However, if malocclusion issues persist despite the previous surgery, additional orthodontic treatment may be necessary to achieve a functional and stable bite.
