Chronic @entity32 is a common process, sometimes requiring nasal and paranasal sinus surgery. Extraocular @entity121 is a rare surgical complication of sinus surgery, but has been reported. Previous studies have been concerned with @entity130 to the medial rectus muscle resulting in severe @entity912 or restriction. This study reports five @entity1 with acquired strabismus and symptomatic vertical @entity892 secondary to sinus surgery. In all @entity1 , the resultant @entity892 was disabling. Four @entity1 had frontal sinus window surgery performed, with incisions placed in the supero-nasal quadrant of the orbit, below the eyebrow (a modified @entity4309 ). Three @entity1 acquired a superior oblique paresis and the fourth developed a @entity10302 . The location of the skin incision was @entity130 in the trochlear area. The fifth @entity1 underwent a nasal polypectomy and antrostomy with @entity548 and @entity5768 . A mild @entity75 was the result.
