Measurement of orbital volume in zygomaticomaxillary complex fractures and its clinical significance
Objective To calibrate the variations of orbital volume of zygomaticomaxillary complex fracture patients, and get the accordance to recover the normal orbital volume and shape, based on three-dimensional reconstruction and computer software technique. Methods 18 patients with the zygomaticomaxillary complex fractures and endophthalmos were scanned by multiple spiral CT, and then, the Simplant analytic software was used to calibrate and compare statistically the intact and traumatized orbital volume. Results Traumatized orbital volume significantly enlarged in all patients, with a mean volume of (1.83±0.75) cm3 compared with the opposite intact orbit (P=0.000). For the males, the intact orbit volume was about (28.50±1.15) cm3, which was significant different with that of the females (23.57±1.31) cm3 (P=0.000). Conclusions The promptly measurement of orbital volume is helpful for making optimal operation plan, recovering accurately the original orbital volume, and avoiding the development of endophthalmos.
