Abstract

PURPOSE: To determine whether patients with Type B orbital blowout fractures (soft-tissue distortion disproportionate to bone-fragment displacement) repaired within 7 days of injury have statistically greater postoperative vertical binocular fusion than similar patients who undergo later surgery.

METHODS: Prospective and retrospective surgical case series. Inclusion criteria were orbital floor (with or without medial wall) blowout fracture repair, preoperative coronal orbital CT scans, and patient age of at least 12 years at time of postoperative binocular visual field.

RESULTS: Twenty-five patients met inclusion criteria. Ten patients (group 1) had surgery within 7 days of injury, and 15 patients (group 2) had surgery more than 7 days after injury. The total cohort had a median postoperative vertical binocular fusion of 90°. Group 1 had postoperative vertical binocular fusion averaging 100°. Nine of 10 patients (90%) were above and 1 of 10 (10%) were below the median for the entire cohort. Group 2 had postoperative vertical binocular fusion averaging 70°. Three of 15 patients (20%) were above and 12 of 15 patients (80%) were below the median for the entire cohort. The difference between the average postoperative vertical binocular fusion of the 2 groups was statistically significant by two-tailed unpaired t test with p value 0.0022.

CONCLUSIONS: Patients with Type B orbital blowout fractures (soft-tissue distortion disproportionate to bone-fragment displacement) have statistically greater average postoperative vertical binocular fusion if repaired within 7 days of injury than similar patients who undergo later surgery.
