Eficacia y seguridad de la sutura ajustable en estrabismos horizontales: estudio comparativo de niños frente a adultos

Abstract

ObjectiveAdjustable suture procedures allow addressing the unpredictability of some postoperative results in strabismus surgery. The purpose of the study was to compare the effectiveness of adjustable and non-adjustable suture in the treatment of horizontal strabismus in children and adults. MethodsProspective study including patients undergoing strabismus surgery to correct horizontal strabismus with fixed hanging suture (non-adjustable suture group) and adjustable suture. Visual acuity, amblyopia, deviation, oblique muscle involvement, previous surgeries, nystagmus, need for adjustment, and complications were recorded. The variables were recorded in the immediate postoperative period, at one week and at 3 and 6months. Results186 patients were included: 157 (84.4%) with adjustable suture and 29 (15.6%) with non-adjustable suture, of which 119 were children and 67 were adults. Postoperatively, 19 children (16.0%) and 19 adults (28.4%) required adjustment (P=.044). Of 157 patients with adjustable suture, it was adjusted in 20% (32/157). Success after adjustment was higher for adjustable suture (91.72% vs 79.31%; P=.043) and remained for 6months (P<.05). Previous surgery (P=.004) and exotropia (P=.018) correlated with the need for adjustment. Conclusions20% of patients with horizontal strabismus can benefit from a postoperative adjustment to improve the surgical result. The adjustable suture was shown to be superior to the fixed hanging suture and is an excellent surgical option, both in children and adults.
