New Surgical Double Interlacing Technique for Correction of Sixth Cranial Nerve Palsy

Abstract

This interventional case series presents a novel surgical procedure involving double interlacing for the correction of esotropia in individuals with sixth cranial nerve palsy. The technique involves first splitting the tendons of the superior rectus, inferior rectus, and lateral rectus muscles. Subsequently, the superior half of the lateral rectus muscle is passed through the undisinserted superior rectus muscle, and the inferior half of the lateral rectus muscle is passed through the undisinserted inferior rectus muscle. Finally, the two halves of the lateral rectus muscle are sutured together and reattached at the original insertion point. The surgical outcomes demonstrate a significant improvement in alignment, abduction, and binocular vision. [ J Pediatr Ophthalmol Strabismus . 2023;60(5):e58–e64.]
