Effect and safety analysis of a new technique of pterygium excision combined with pedicled conjunctival flap transplantation

ObjectiveTo explore the effects and safety of the new technique of pterygium excision combined with pedicled conjunctival flap transplantation.

MethodsOne hundred patients(103 eyes) with pterygium surgery were divided into the observation group and control group according to the random number table(50 cases in each group).The observation group(53 eyes) was treated with the modified pterygium excision combined with pedicled conjunctival flap transplantation(the shape of pedicled conjunctival flap was made into trapezoid, which was consistent with the shape of surgical defect area, the amount of conjunctival cutting reduced, the suture was less.The control group(50 eyes) was treated with simple resection combined with stem cell transplantation.Two groups were followed up for 6 months, and the operation time, conjunctival flap healing time, recurrence rate, best corrected visual acuity after 4 weeks of operation and postoperative complications were compared between two groups.

ResultsCompared with the control group, the operation time and conjunctival flap healing time were shorter, and the postoperative irritation symptoms was lighter in the observation group(P < 0.05 to P < 0.01), the difference of the recurrence rate between two groups was not statistically significant within 6 months of following-up(P>0.05), and there was no statistical significance in the best corrected visual acuity and symblepharon complications after 4 weeks of operation between two groups(P>0.05).

ConclusionsThe new technique of pterygium excision combined with pedicled conjunctival flap transplantation has ideal clinical effects, high safety and certain clinical promotion value.
