Surgical treatment of enophthalmos in children and adolescents with pure orbital blowout fracture.

PURPOSE

This study evaluated outcomes of surgical treatment for enophthalmos after pediatric orbital blowout fracture. Associations of fracture type, fracture site, time from injury to treatment, and type of surgical procedure with treatment outcomes were assessed.

METHODS

The medical records of 200 children and adolescents (38 girls and 162 boys) with orbital fractures treated in the authors' department from 1975 to 2015 were reviewed retrospectively. The main causes of injury were accidental blows to the orbit and sports injuries. This study included only patients with fracture of the floor and/or medial wall of the orbit, which is referred to in the English literature as pure, or internal, blowout fracture. Patients with fracture of the orbital rim, lateral wall, or roof were excluded. Surgical treatment was performed for 178 patients; the other 22 children were treated conservatively.

RESULTS

In the surgically treated group, treatment outcomes did not differ in relation to the severity of post-traumatic enophthalmos. The setting of the eyeball improved in 83% of patients.

CONCLUSION

The severity of post-traumatic enophthalmos was not associated with surgical outcome in children.
