This systematic review and meta-analysis compared autologous bone grafts and alloplastic implants for orbital floor reconstruction in 2,119 patients. Alloplastic implants showed a statistically significant lower risk of postoperative ectropion (RR = 2.245; p = 0.020) and were associated with less donor-site morbidity, suggesting they may be a safer alternative to autologous grafts.
Key findings
- Alloplastic implants had a reduced risk of postoperative ectropion compared to autologous grafts (RR = 2.245; p = 0.020).
- Autologous grafts were linked to a higher risk of implant malposition (RR = 2.074; p = 0.004).
- No significant differences were found in infection rates, enophthalmos, or diplopia between the two groups.
Why it matters
The findings highlight the potential advantages of alloplastic implants in reducing surgical complications and donor-site morbidity, which are critical considerations in reconstructive surgery. Understanding these differences can guide clinicians in making informed decisions regarding orbital floor reconstruction materials.
What to keep in mind
The evidence base is predominantly retrospective and heterogeneous, indicating a need for further high-quality randomized trials.
