“…Thacker et al [13] have reported injury to the multiple extra ocular muscles including inferior rectus and superior oblique in their series; only one of the patients in our series (Case 5) had involvement of another ocular muscle (IR).…”

“…In pattern I of Huang's classification, where complete transection of the medial rectus is seen, immediate orbital exploration is indicated to reattach the cut ends of the muscle. Thacker et al have recommended that retrieval and reattachment should be attempted only if there is muscle contractility as seen on multipositional MRI scan or if the patient presents within 3 months in the acute phase because of the potential for recovery from the nerve damage [13]. They have also suggested that in cases with transection injury, if the remaining posterior segment of the MR is longer than 20 mm and is functional, muscle recovery via anterior orbital approach should be attempted via a transconjunctival or modified Lynch incision.…”

“…To prevent this complication several approaches have been described which include injection of botulinum toxin into the lateral rectus muscle [20] or the placement of a posterior fixation suture (augmented transposition surgery) [21]. Inactivating lateral rectus muscle and use of a periosteal flap to centre the eyeball has also been reported [13].…”

Endoscopic sinus surgery (ESS) is the mainstay of the treatment in sinus disorders, to re-establish the drainage of the affected sinus. The close proximity of the orbital structures to paranasal sinuses makes them vulnerable to inadvertent injury during the sinus surgery. Medial rectus (MR) muscle is the most commonly injured extraocular muscle during ESS due to its anatomic proximity to the thin medial wall of the orbit. This is a non-comparative, retrospective, interventional case series of six patients presenting with MR injury after ESS. We discuss the management, outcome and review the published literature. A total of six patients met the inclusion criteria. The presenting complaints were diplopia, squinting and limitation of ocular movements. Two patients underwent surgical exploration of the MR muscle and reattachment of the muscle along with injection botulinum to the antagonist lateral rectus muscle. Two patients who had small angle strabismus and who were able to fuse were advised orthoptic exercises and prisms as management. Remaining two patients were advised surgical intervention to correct strabismus but they declined further surgical intervention. Management of MR injury following ESS is complex, often resulting in suboptimal outcomes. Since early intervention is associated with better outcomes, early referral by otolaryngologists to ophthalmologists would result in better outcome.

“…Lost MR due to endoscopic sinus surgery causes a large exotropia with no adduction, and usually spares the vertical recti. Several authors described transposition for this condition with or without concomitant lateral rectus (LR) weakening by recession or botulinum toxin, (Cho et al, 2008;Lee et al, 2002;Olitsky & Brooks, 2001;Thacker et al, 2004), reporting variable outcome. In cases of combined transposition and lateral rectus recession, the risk of anterior segment ischemia was reduced by vessel sparing procedures in most cases.…”

Vertical Muscle Transposition with Augmentation for Treatment of Exotropia Caused by Iatrogenic Lost Medial Rectus Muscle

2016

Purpose: To evaluate the results of vertical muscle transposition with augmentation in cases of exotropia caused by iatrogenic lost medial rectus muscle.Methods: This is a retrospective review of 5 cases of lost medial rectus with exotropia and marked limitation of adduction that underwent surgery. All cases had a history of strabismus surgery on the medial rectus and failed attempt at retrieval of the lost muscle.
