Myectomy with or without proximal end tucking for inferior oblique overaction
Reviewed by Fiona Rowe

This study aimed to compare the outcomes and impact of inferior oblique muscle myectomy with and without tucking the proximal end of the muscle into Tenons capsule in two surgical groups as a treatment for inferior oblique overaction. Tucking the proximal end into the space where the inferior oblique muscle penetrates to Tenons capsule has been proposed to prevent reattachment of the muscle into the sclera. This was a randomised prospective cohort design with two surgical groups with recruitment of 33 patients (55 eyes). The median age was six years; 19 males. Sixteen patients (28 eyes) underwent inferior oblique muscle myectomy with tucking (group 1) and 17 (27 eyes) underwent myectomy without tucking (group 2). At six-months follow-up 51 eyes (92.7%) had complete resolution of the inferior oblique overaction. There was no significant difference between groups for outcomes. Success rate was 92.58% for group 1 and 92.59% for group 2. The results suggest both surgical techniques are highly successful in eliminating inferior oblique overaction and associated hypertropia. Neither technique demonstrated superior efficacy or a faster rate of correction.
