Purpose:
Retrospective evaluation of 41 proptosis reduction procedures using fat removal orbital decompression (FROD) according to a modified Olivari's technique.
Methods:
Trans-septal excision of extraconal and intraconal fat was done under the microscope through the upper and lower eyelid blepharoplasty approach. Proptosis was measured with a Hertel exophthalmometer.
Results:
Mean excision of 7.31 + 1.9 ml (range 3.25-12 ml) of orbital fat reduced proptosis on average by 4.7 + 2.4 mm (range 1-11 mm). Side effects were few, limited only to ocular motility disturbances. There was no significant effect on visual fileds. A postoperative drop in IOP was noted in patients with preoperative IOP above 21 mmHg. Efficient palpebral lengthening can be achieved with combined section of the levator aponeurosis horns in the upper eyelid, and/or auricular cartilage graft in the lower eyelid.
Conclusions:
FROD reduces proptosis in Grave's ophthalmopathy.
