Summary
Fibrin tissue adhesive significantly reduced pterygium surgery recurrence compared to sutures. This novel technique for conjunctival transplants offers a safer, more effective surgical outcome for patients.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Ocular Surface Disease
Background:
- Pterygium surgery aims to remove abnormal conjunctival growth.
- Recurrence after pterygium excision remains a significant clinical challenge.
- Current techniques for graft fixation vary, impacting outcomes.
Purpose of the Study:
- To compare the efficacy of fibrin tissue adhesive versus absorbable sutures for conjunctival graft fixation in pterygium surgery.
- To evaluate recurrence rates, reoperation rates, and complications associated with each fixation method.
Main Methods:
- Retrospective study of 461 eyes from 381 patients undergoing primary nasal pterygium excision.
- Autologous conjunctival grafts were used, fixed with either fibrin tissue adhesive (n=325) or absorbable sutures (n=136).
- Follow-up period averaged 23 months to assess outcomes.
Main Results:
- The fibrin glue group showed a significantly lower recurrence rate (5.3%) compared to the suture group (13.5%, p=0.01).
- Reoperation rates were similar between groups (1.2% glue vs. 3.3% sutures, p=0.31).
- Complication rates, including edema and epithelial defects, were comparable in both groups.
Conclusions:
- Fibrin tissue adhesive is a superior method for securing conjunctival grafts in pterygium surgery.
- This technique leads to a statistically significant reduction in pterygium recurrence.
- Fibrin adhesive offers a safe and effective alternative to sutures for graft fixation.
