Abstract
Intraoperative imaging enables the surgeon to control the position of the implant
during orbital reconstruction. Although it might improve surgical outcome and avoid
the need for revision surgery, it may also increase the duration of the operation
and the exposure to radiation. The goal of this study was to find out whether intraoperative
imaging improves the position of the implant in reconstructions of the orbital floor
and medial wall. Two surgeons reconstructed complex orbital fractures in 10 cadavers.
After the reconstruction a computed tomographic scan was made to confirm the position
of the implant and, if required, to make any adjustments. Scans were repeated until
the surgeon was satisfied. The ideal position was ascertained by scans that were obtained
before and after creation of the fractures. The position of the implant achieved was
compared with that of the ideal position of the implant, and improved significantly
for yaw (p = 0.04) and roll (p = 0.03). A mean of 1.6 scans was required for each reconstruction (maximum n = 3). The main reason for alteration was the rotation roll. Intraoperative imaging significantly
improves the position of the implant in fractures of the orbital floor and medial
wall. The surgeon has quality control of its position during the reconstruction to
restore the anatomical boundaries.
