The proportion of perforation sites in the small-sized and medium-sized perforations did not differ significantly between groups (p = 0.215 and p = 0.528, respectively). Graft success rates did not differ based on perforation size (small vs medium, p = 0.303) or location (anterior vs posterior, p = 0.503).
