To introduce an improved technique of pterygium surgery and to compare postoperative results between this technique and previous techniques.


In a retrospective survey, the records of 216 consecutive eyes with primary pterygium that underwent surgery by three different techniques were reviewed. The new technique (mini-flap technique) involves making a small excision of the pterygium body, removing the pterygium head by scraping with forceps, applying mitomycin C (MMC), and performing a small conjunctival transposition flap. The previous technique (large-flap technique II) involved making a large excision in the pterygium body, removing the pterygium head with a knife, applying MMC, and performing a large transposition flap. Large-flap technique I is the same as large-flap technique II except for the use of intraoperative MMC. The recurrence rate of each technique was estimated by the Kaplan-Meier life table analysis.


The recurrence rates estimated at 1 year after surgery were 15.5% in large-flap technique I, 4.2% in large-flap technique II, and 0% in the mini-flap technique. Large-flap technique II or the mini-flap technique had significantly lower recurrence rates compared with large-flap technique I ( p = 0.02 and p < 0.01, respectively). The mini-flap technique had a significantly lower incidence of conjunctival scarring or granuloma compared with large-flap technique I and large-flap technique II ( p = 0.05 and p = 0.03, respectively.)


The mini-flap technique was useful for preventing recurrence and was technically easier and induced fewer postoperative complications than large-flap techniques I and II.
