Abstract:
Background/Objectives: This network meta-analysis aimed to evaluate and compare the risks of lower eyelid complications-ectropion, entropion, scleral show, and postoperative scarring-associated with four surgical approaches (subciliary, subtarsal, infraorbital, and transconjunctival) for orbital and zygomaticomaxillary fracture repair. Methods: A systematic search of PubMed, Embase, and Cochrane databases identified relevant studies published between 1 January 1990 and 10 January 2026. Twenty-seven eligible studies involving 2790 patients were included. Direct pairwise meta-analyses and network meta-analyses were conducted to compare complication risks among the approaches. Sensitivity analyses were performed to assess the influence of individual studies, and inconsistency tests were applied to evaluate model robustness. Results: The subciliary approach was associated with the highest risk of ectropion and scleral show. The transconjunctival approach had the lowest risk of ectropion and scarring but the highest risk of entropion. The subtarsal approach had the lowest risk of scleral show, while the infraorbital approach had the highest risk of postoperative scarring. Sensitivity analyses confirmed consistent rankings, and no significant inconsistency was detected. Conclusions: This study provides updated, comprehensive evidence to guide the choice of surgical approach for orbital and zygomaticomaxillary fracture repair. Surgeons should balance operative exposure, cosmetic outcomes, and complication risk, and communicate these trade-offs clearly with patients to optimize decision-making.
Insights
The subciliary approach poses the highest risk for ectropion and scleral show in orbital fracture repair. The transconjunctival approach offers lower ectropion and scarring risks but increases entropion risk.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Maxillofacial Surgery
Background:
- Orbital and zygomaticomaxillary fractures require surgical repair.
- Lower eyelid complications can arise from different surgical approaches.
- Comparing complication risks is crucial for patient outcomes.
Purpose of the Study:
- To compare risks of ectropion, entropion, scleral show, and scarring.
- To evaluate four surgical approaches: subciliary, subtarsal, infraorbital, and transconjunctival.
- To provide evidence for optimizing surgical technique selection.
Main Methods:
- Network meta-analysis of 27 studies (2790 patients).
- Systematic literature search (PubMed, Embase, Cochrane).
- Direct pairwise and network meta-analyses, sensitivity, and inconsistency analyses.
Main Results:
- Subciliary approach: highest risk of ectropion and scleral show.
- Transconjunctival approach: lowest ectropion/scarring risk, highest entropion risk.
- Subtarsal approach: lowest scleral show risk; Infraorbital approach: highest scarring risk.
Conclusions:
- Evidence guides surgical approach selection for orbital fractures.
- Surgeons must balance exposure, aesthetics, and complication risks.
- Clear patient communication on trade-offs is essential for decision-making.
