Abstract
Purpose
To analyze the long-term clinical outcomes after use of fibrin glue using a modified mini-flap technique for pterygium surgery.
Methods
This study is a retrospective, clinical outcome study of 148 subjects that underwent the modified mini-flap technique with fibrin glue from January 2014 to August 2015. We analyzed the recurrence rate and surgical time of modified mini-flap sur-gery with fibrin glue. We also analyzed associating factors between the recurrence group and non-recurrence group who under-went the same surgery technique.
Results
Mean age was 60.2 ± 1.1 (ranging from 29 to 86) years, and mean surgical time was 11.8 ± 5.8 (ranging from 5 to 36) minutes. The recurrence rate of pterygium patients who underwent the fibrin glue using a modified mini-flap technique was 4.0% (6/148), and the re-operation rate was 0.6% (1/148). From the comparison of associating factors between recurred and non-re-curred groups, the recurred group was younger, had more severe disease, and had a higher rate of bilaterality than the non-re-curred group (p < 0.05).
Conclusions
The new approach using fibrin glue with a modified mini-flap technique shows a low recurrence rate compared to the other type of pterygium surgery. The use of fibrin glue shortened operation time and decreased patient discomfort due to few-er remnant sutures. Fibrin glue use in a modified mini-flap technique can be considered as a feasible surgical option for ptery-gium patients.
