To evaluate the clinical aspects associated with the preoperative and postoperative state of blow-out fractures in preschool children.

The authors of the present study retrospectively reviewed 11 cases of blow-out fracture repaired by orbital reconstruction.

The most common cause of fracture was a traffic accident (45%); there were 7 cases (63%) of inferior wall fracture and 7 cases (63%) of trapdoor-type fracture. All patients with trapdoor-type fractures had nausea and vomiting. After the operation, the majority of patients (88%) had mild ocular motility restriction and diplopia.

In preschool children, systemic symptoms such as nausea and vomiting presented frequently. In addition, complications such as restriction in ocular movement and diplopia often developed postoperatively.
