Strabismus following Endonasal sinus surgery: a 10-year retrospective analysis of clinical profile and outcomes.
Half of patients with strabismus after sinus surgery needed surgical correction, often incomplete.
Strabismus following Endonasal sinus surgery: a 10-year retrospective analysis of clinical profile and outcomes.
To evaluate the clinical characteristics, motility deficits, strabismus patterns, and management outcomes in patients developing strabismus following Endonasal Sinus Surgery (Endonasal Sinus Surgery).
This retrospective study was conducted over 10 years (2015-2025) at a tertiary eye care center.
half needed a second surgery to fix the eye misalignment, often not fully
Ten patients were identified, with male-to-female ratio of 4:1 (8:2) and mean age of 40.3 years (range 24-62 years).
Ocular motility limitation was present in ( n = 9; 90%) patients.
Limitation of adduction was most commonly present involving the medial rectus n = 7; 70%.
One patient (10%) was lost to follow up and did not receive further management.
Strabismus is a rare but a significant (functional) complication following Endonasal sinus surgery, typically presenting as restrictive large-angle exotropia.
Surgical correction and prisms provide functional improvement, though complete resolution is uncommon considering the extent of the injury. Early recognition and multidisciplinary management are crucial to optimize outcomes.
