Abstract :

The aim of work was to assess anatomical and functional results of surgically treated orbital floor fractures in relation toCT navigation surgery.In the interval of 2007 &ndash; 2013, we surgically treated 40 blow&ndash;out fractures of the orbital floor.A series was divided into two groups identical in number. The first group comprisedeightwomen and 12 men. The second group comprised six women and 14 men.The first group was operated without CT navigation (7 times from subtarsal approach, 13 times from transantral approach). The second group had 7 times transantral approach and 13 times from subtarsal. Patients stated preoperative diplopia in the first group 18 times, in the second group 20 times. Diplopia was revealed after the surgery in the first group in four cases (20 %), diplopia was not revealed in the second group (0 %). Enophthalmos was identified preoperatively in all patients in both groups, and postoperatively in the first group in thre (15 %), in the second group in two patients (10 %).Computer assisted surgery showed better functional and anatomical results than surgery without CT navigation. We did not find diplopia in any operated patient with CT navigation in postoperative period. We did not notice relation of diplopia to operation approach and use of fixation materials.
