XXXX to Medial Rectus After Endoscopic Sinus Surgery.

@entity1 @entity892 @entity50 @entity130
Endoscopic sinus surgery (ESS) is the mainstay of the treatment in @entity50 , 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 @entity1 presenting with @entity130 after ESS. We discuss the management, outcome and review the published literature. A  total  of six @entity1 met the inclusion criteria. The presenting complaints were @entity892 , squinting and limitation of ocular movements. Two @entity1 underwent surgical exploration of the MR muscle and reattachment of the muscle along with injection botulinum to the antagonist lateral rectus muscle. Two @entity1 who had small angle strabismus and who were able to fuse were advised orthoptic exercises and prisms as management. Remaining two @entity1 were advised surgical intervention to correct strabismus but they declined further surgical intervention. Management of @entity130 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.
