Summary
Thicker dermis fat grafts (20 mm) significantly reduce enophthalmos and superior sulcus deformity in orbital reconstruction. This approach maintains prosthesis motility and graft success, improving cosmetic outcomes.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Reconstructive Surgery
Background:
- Dermis fat grafts are widely used for orbital reconstruction.
- Limited controlled studies exist on their long-term effectiveness.
- This study prospectively evaluates 40 patients undergoing orbital reconstruction with dermis fat grafts.
Purpose of the Study:
- To compare the long-term cosmetic results of two dermis fat graft thicknesses (10 mm vs. 20 mm) in orbital reconstruction.
- To assess the impact of graft thickness on socket adequacy, lid anomalies, superior sulcus deformity, exophthalmometry, and prosthesis motility.
Main Methods:
- A prospective study involving 40 patients undergoing primary or secondary orbital dermis fat grafting.
- Grafts of 10 mm and 20 mm fat pad thickness were used, with other parameters standardized.
- Outcomes including socket adequacy, lid anomalies, superior sulcus deformity, exophthalmometry, and prosthesis motility were periodically assessed.
Main Results:
- The 20 mm fat pad thickness group showed a significantly lower incidence of enophthalmos.
- Superior sulcus deformity was also significantly reduced in the 20 mm group.
- Graft take and prosthesis motility were not compromised by the thicker graft.
Conclusions:
- A 20 mm fat pad thickness for dermis fat grafts in orbital reconstruction leads to superior cosmetic results.
- This thicker graft effectively addresses enophthalmos and superior sulcus deformity.
- The use of 20 mm grafts is recommended for improved outcomes in orbital reconstruction without compromising function.
