Purpose The visco‐elastic features of silicone oil are a limiting factor transconjunctival vitreoretinal surgery. The flow resistence increases with the reduction of the inner diameter of the extrusion canula. Thise increases the duration of silicone oil extraction. The purpose of this study was to compare 2 surgical procedures for silicone oil extrusion: 20 versus 23 Gauge. Methods A retrospective pilot study compared two groups of patients scheduled for silicone oil extraction. In the first group silicone oil extraction was performed through a 20 Gauge scllerotomy after conjunctival dissection whereas a 25 Gauge tranconjunctival sclerotomy enabled saline infusion. In the second group both infusion and silicone oil extraction was performed through 23 Gayge transconjunctival sclerotomies. The duration of each procedure was the main outcome measure. Results The mean duration of the 23 Gauge procedure was 42 minutes compared with 22 minutes in the combined 20/25 Gauge procedure. Transitory intraoperative hypotonia was encountered in two patients, one in each group. During the post‐operative follow up, a vitreous hemorrhage occurred in one patient of the 23 Gauge procedure group. Conclusion Comparing two surgical procedures for silicone oil extraction, the conjunctival dissection time in the 20/25 Gauge group seems to be largely counterbalanced by the rapidity of the silicone oil extraction through a larger sclerotomy. The use of a combined 20/25 Gauge full transconjunctival procedure could probably reduce furthermore the duration of surgery .
