Curious about how much swelling subsides one month after double jaw surgery? This case study examines the recovery progress of a patient who underwent a combination of procedures. In my experience, individuals with lower body fat percentages (below 20%) tend to see faster facial settling. This patient fits that profile, allowing us to observe a potentially quicker recovery.
Pre-Surgery Assessment
The patient sought treatment for facial asymmetry and a weak chin.
Clinical Examination: A noticeable deviation of the jaw to the right and a retruded chin were observed.
facial asymmetry and a weak chin CT Scan Analysis: The chin was deviated 6.48 mm to the right and positioned roughly 8 mm posterior to the ideal position in the side view. The analysis revealed both a deficient chin and asymmetry. Importantly, the lower front teeth were angled forward, making it difficult to achieve sufficient forward movement of the lower jaw with counter-clockwise rotation double jaw surgery alone.

Surgical Approach: Counter-Clockwise Rotation Double Jaw Surgery + Anterior Segmental Osteotomy (ASO)
To address the patient's concerns, a combined surgical approach was chosen, involving both counter-clockwise rotation double jaw surgery and ASO (a procedure to reposition the front part of the jaw).
Why ASO Was Included
Looking at the pre-surgical analysis, the need for ASO might not be immediately obvious. The front-to-back position of the upper jaw, as measured by SNA or A to N-Perp, appears to be within the normal range or even slightly back.
So why add ASO?
The key reason was to maximize the forward movement of the lower jaw. Without ASO, achieving the desired lower jaw advancement while maintaining the position of the upper front teeth would have been challenging.
To illustrate this, I've created images using CAD software. By comparing the side profiles with and without ASO, while keeping the upper front teeth in the same position, we can see a significant difference in the lower jaw's position.
With the combined procedure, the lower jaw could be moved forward by over 6 mm while preserving the upper teeth' position. This highlights that even in cases without significant protrusion, ASO can be crucial during double jaw surgery to ensure adequate lower jaw advancement. This allows for optimal positioning of both the upper and lower jaws.
4 Weeks Post-Surgery Results
Improved Symmetry: Facial asymmetry has been significantly corrected.
Double Jaw Surgery at 1 Month Advanced Lower Jaw: The lower jaw has been successfully moved forward.
Double Jaw Surgery at 1 Month Stable Condyle Position: Comparison of pre- and post-operative condyle positions shows minimal change. This is vital to prevent relapse or post-surgical complications.
Reduced Swelling: A substantial decrease in lip swelling is observed compared to 3 days post-op.
One month Postop swelling
Conclusion:
At the one-month mark after double jaw surgery, significant swelling reduction and noticeable skeletal changes are evident. In this case, the combined approach of counter-clockwise rotation double jaw surgery and ASO led to successful outcomes.

Important Note: Recovery and results can vary between individuals undergoing double jaw surgery. A detailed consultation with a qualified surgeon is essential for personalized surgical planning.
