Adjustable suture strabismus surgery in infants and children: a 19-year experience

Abstract

To evaluate the success rate of adjustable suture techniques in horizontal eye muscle surgery in children ≤15years of age over a 19-year period by a single surgeon. The medical records of all consecutive patients in this age group who underwent horizontal eye muscle surgery from 1989 through 2012 were reviewed retrospectively. Patients were divided into two groups: those in whom a nonadjustable suture technique was used and those in whom adjustable sutures were used. The following data were collected: type of strabismus, preoperative measurements, postoperative results, and reoperation rates. A total of 116 cases in the nonadjustable group and 521 cases in the adjustable group were included. In the adjustable group, adjustment was performed in 63% of the cases, because of either an under- (41%) or overcorrection (22%). The adjustment procedure was performed under topical proparacaine in 15% of cases and under intravenous propofol in 85%. For the adjustable group, 3-5minutes more per muscle intraoperatively and 15-20minutes for adjustment were required. No complications were encountered during the adjustment procedures. Early success rate, defined as alignment within 8Δ of straight at 3 to 6months' postoperative follow-up, was significantly greater in theadjustable group than in the nonadjustable group (77.7% vs 64.6% [P≤0.03]). Of the adjustable patients, 15% required reoperation compared with 21% of the nonadjustable patients. Use of adjustable sutures in horizontal eye muscle surgery in children ≤15years of age provided an improved success rate and fewer reoperations compared with nonadjustable sutures.
