Graded recession technique versus myectomy in management of inferior oblique muscle overaction

Abstract

Aim The aim of this study was to compare two surgical techniques of inferior oblique muscle weakening in the management of inferior oblique overaction whether primary or secondary, that is, inferior oblique myectomy and graded inferior oblique muscle recession. Patients and methods This is a randomized prospective study, performed in Alexandria, Egypt, that included cases of inferior oblique muscle overaction, whether primary or secondary, starting on May 2020. It included 40 patients, divided into two groups: group I included 20 patients who were managed by inferior oblique myectomy, and group II included 20 patients who were managed by graded inferior oblique muscle recession, according to the clinical grading of overaction. Results The results of the two groups were compared, and it was found that the results were comparable as the final outcomes of correction of hypertropia were satisfactory in both groups. Conclusion As the results in both techniques have no significant difference, it is recommended that each surgeon should perform his/her preferred technique.
