Comparative Orbital Volumes between a Single Incisional Approach and a Double Incisional Approach in Patients with Combined Blowout Fracture

الملخص EN

Purpose.

Blowout fracture characterized by concurrent floor and medial wall fractures is a rare entity.

We compared surgical outcomes between a single approach and a double approach in patients with orbital fracture by measuring the postoperative orbital volume.

Methods.

We confirmed that 21 (8.5%) of a total of 246 patients with orbital fractures had fractures of the medial wall and floor through a retrospective chart review.

Of these, 10 patients underwent the single approach and the remaining 11 patients had the double approach.

We performed a statistical analysis of changes between the preoperative and postoperative orbital volumes at a 6-month follow-up.

Results.

Compared with the contralateral, nonaffected side, the orbital volume was 115.3 (±6.09)% preoperatively and 106.5 (±6.15)% postoperatively in the single approach group and 118.2 (±11.16)% preoperatively and 108.6 (±13.96)% postoperatively in the double approach.

These results indicated that there was a significant difference between the preoperative and postoperative orbital volumes in each group (P<0.05).

However there was no significant difference between the single approach and the double approach (P>0.05).

Conclusions.

Our results showed that there were no significant differences in surgical outcomes between the two modalities.

The treatment modality may be selected based on the surgeons’ preference, as well as the fracture type.
