Summary
Suprafascial dissection during coronal incisions minimizes temporal hollowing, a common complication. Minimizing patient weight loss also helps prevent this aesthetic and psychological issue.
Area of Science:
- Plastic Surgery
- Facial Reconstruction
- Anatomy
Background:
- Coronal incisions are vital for accessing the lateral facial skeleton in various surgical procedures.
- Temporal hollowing is a frequent and distressing complication following coronal incisions.
- Current techniques aim to protect the frontal nerve and temporal fat pad to prevent hollowing.
Purpose of the Study:
- To determine the primary cause of postoperative temporal hollowing after coronal incisions.
Main Methods:
- Prospective study randomizing coronal incision sides to suprafascial, subfascial, or deep dissection.
- Clinical assessment and CT volume analysis measured temporal hollowing severity at 6 months.
- Ensured equal distribution of dissection types using sealed envelopes.
Main Results:
- Suprafascial dissection demonstrated the lowest incidence and severity of temporal hollowing.
- Postoperative temporal hollowing correlated with surgical approach and weight loss.
- No frontal nerve injuries were reported across all dissection types.
Conclusions:
- Performing coronal flap elevation in the suprafascial plane can reduce temporal hollowing.
- Minimizing patient weight loss post-surgery is recommended to decrease hollowing incidence.
