Summary

This summary is machine-generated.

Polycaprolactone (PCL) and unsintered hydroxyapatite particles/poly-L-lactic acid (uHA/PLLA) meshes show similar safety and surgical outcomes for orbital fracture repair. Both implants offer comparable complication rates and functional results in orbital wall reconstruction.

Background:

Orbital fracture repair presents challenges due to varying material properties of implants.
Polycaprolactone (PCL) and unsintered hydroxyapatite particles/poly-L-lactic acid (uHA/PLLA) are commonly used meshes with distinct handling characteristics.

Purpose of the Study:

To compare the surgical outcomes and postoperative implantation accuracy of PCL and uHA/PLLA meshes in orbital fracture repair.
To evaluate functional results including diplopia, ocular motility, and enophthalmos.

Main Methods:

Retrospective analysis of patients undergoing orbital wall reconstruction using PCL or uHA/PLLA mesh (2017-2019).
Assessment of anatomical accuracy of implant placement within bony defects.
Evaluation of functional outcomes such as diplopia, ocular motility, and enophthalmos at 6 months postoperatively.

Main Results:

No significant differences in surgical outcomes (diplopia, enophthalmos) or complications were observed between the PCL and uHA/PLLA groups.
Excellent anatomical accuracy was noted in 27/30 PCL patients and 22/30 uHA/PLLA patients.
No patient experienced restricted eye movement in either group.

Conclusions:

Both PCL and uHA/PLLA implants are safe and effective for orbital wall reconstruction.
The study demonstrates similar complication rates and surgical outcomes for both implant types.
These findings support the use of either PCL or uHA/PLLA in orbital fracture repair based on surgeon preference and specific case needs.
