Abstract:
Porous polyethylene is a widely used implants in orbital reconstruction, on which comprehensive clinical analysis, various treatments, and different prognosis according to specific classification principles on long-term complications have not been reported.To investigate the new clinical symptoms, intraoperative findings, treatments, and outcomes of complications long period after previous surgery, resulting from the use of porous polyethylene mesh for orbital fracture reconstruction.A retrospective study was conducted on 21 patients at the Department of Ophthalmology, Shanghai Ninth People's Hospital with orbital complications after orbital fracture reconstruction with porous polyethylene mesh for 4 ± 2.2 years from 2011 to 2013. These data included new clinical symptoms after previous surgery, computerized tomography data, intraoperative findings, treatments, and outcomes.Data from 21 patients were analyzed in this study. Two patients received conservative treatment, while the other 19 patients underwent surgical approaches. Classification principles for orbital complications after orbital wall defect reconstruction with porous polyethylene mesh were formulated according to patients' new clinical symptoms, computed tomography (CT), and intraoperative findings after previous surgery. In the last follow-up, 19 patients (90.5%) were cured or improved according to our assessment principle. The follow-up ranged from 3 to 45 months (35 months in average).According to specific classification for orbital complications resulting from the use of porous polyethylene mesh for orbital fracture reconstruction, various medical treatments should be carried out, and the prognosis may be different.
Insights
Long-term complications from porous polyethylene orbital reconstruction were analyzed. A new classification system for these orbital complications led to successful treatment outcomes in 90.5% of patients.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Medical Engineering
Background:
- Porous polyethylene is a common implant for orbital reconstruction.
- Comprehensive analysis of long-term complications, treatments, and prognoses for porous polyethylene implants is lacking.
- Understanding these complications is crucial for improving patient outcomes.
Purpose of the Study:
- To investigate clinical symptoms, intraoperative findings, treatments, and outcomes of long-term complications after orbital fracture reconstruction using porous polyethylene mesh.
- To develop classification principles for these orbital complications.
- To correlate treatment strategies with patient prognosis.
Main Methods:
- A retrospective study of 21 patients with orbital complications after porous polyethylene mesh reconstruction.
- Data collected included clinical symptoms, CT scans, intraoperative findings, treatments, and outcomes.
- Follow-up ranged from 3 to 45 months (average 35 months).
Main Results:
- 19 out of 21 patients (90.5%) achieved cure or improvement.
- A classification system for orbital complications was formulated based on clinical, CT, and intraoperative findings.
- Two patients received conservative treatment; 19 underwent surgical intervention.
Conclusions:
- A specific classification system for orbital complications from porous polyethylene mesh is proposed.
- Tailored medical treatments based on this classification can lead to varied but often positive prognoses.
- This study provides a framework for managing long-term complications in orbital reconstruction with porous polyethylene.
