Abstract:
Dysfunction of one or more of the ocular motor nerves or extraocular muscle injury commonly results in diplopia. Diplopia during endoscopic sinus surgery is caused by surgical trauma or local anesthetics. Transient abducens nerve palsy rarely occurs after an intranasal sphenopalatine nerve block. We report three cases of transient abducens nerve palsy during endoscopic sinus surgery and possible explanations are proposed with a review of literature.
