Summary
Facial fat compartments are severely underdeveloped in Treacher Collins syndrome (TCS), impacting facial deformity. Understanding and restoring these fat compartments is crucial for early surgical treatment of TCS.
Area of Science:
- Craniofacial surgery
- Plastic surgery
- Medical imaging
Background:
- Treacher Collins syndrome (TCS) involves midfacial skeletal hypoplasia.
- Associated soft tissue hypoplasia in TCS is not well-studied and presents treatment challenges.
Purpose of the Study:
- To qualitatively and quantitatively analyze midfacial fat compartments in individuals with TCS.
- To compare TCS fat compartment morphology to a control group.
Main Methods:
- Magnetic resonance imaging (MRI) was used to study prezygomatic and buccal fat pads.
- Two individuals with TCS (ages 10 and 14) and 20 age-matched controls were analyzed.
- Morphometric analysis and comparison were performed.
Main Results:
- Midfacial fat compartments in TCS patients were found to be severely hypoplastic, particularly in superficial and lateral facial areas (P < 0.001).
- No significant correlation was found between soft tissue and skeletal involvement in TCS.
Conclusions:
- This study presents the first analysis of midfacial fat compartments in TCS.
- Hypoplasia of these fat compartments is a significant component of TCS facial deformity.
- Understanding fat compartment anatomy and volume is essential for effective early surgical reconstruction in TCS.
