Objective: To recognize the indication and the value of transantral orbit decompression to malignant ophthalmopathy.
Method: 9 eyes of 5 cases undergone transantral orbital decompression from November 1986 to October 1998 were reviewed.
Result: After 3 months-2 years of follow-up. We found this approach successfully improved visual function of all 5 cases. Average proptosis reduction was 5 mm. The eye lids could be closed in 4 of the 5 cases and the palpebral fissures was decreased 1-2 mm in 1 of the 5 cases. Preoperative exposure keratitis resolved in both of the 2 cases. Diplopia was cured in both of the 2 cases. Secondary glucorna also recovered in both the 2 cases. Disturbance of ocular motility in both of the 2 cases improved postoperatively and preoperative visual acurity worsen also improved in both of the 2 cases.
Conclusion: It has been suggested that the transantral decompression of the orbit provided a safe, effective therapeutic modality for patients with vision-threatening or major cosmetic problem.
