Background
The aim of this study was to evaluate the long-term outcomes after unilateral orbital fat decompression in patients with thyroid eye disease.
Design
Retrospective, comparative, cross-sectional study
Participants
Thirty-three orbits of 33 patients were included in this study. Of the 33 patients, 13 underwent fat decompression (group A), and the other 20 had bony decompression (group B).
Methods
The medical records of patients who underwent orbital decompression to reduce proptosis for thyroid eye disease were retrospectively reviewed. The degrees of proptosis were measured by Hertel exophthalmometry preoperatively and over a follow-up period of more than 3 years. We evaluated the change in proptosis after surgery.
Main outcome measures
Postoperative change in exophthalmos.
Results
A recurrence in proptosis from fat decompression was seen in ten patients (76.9 %) in group A and in only two patients (10 %) in group B. The amount of regression due to surgery after 3 years was 2.3 ± 1.4 mm and 0.7 ± 0.9 mm in groups A and B respectively. The tendency of regression was more prominent in group A than in group B.
Conclusion
The long-term effect of unilateral orbital fat decompression for the reduction of proptosis in patients with thyroid eye disease may be weak, leading to regression. Care should be taken when determining the extent of fat decompression with consideration for this tendency.
