A new radiological method was used to evaluate the plastic effect of modified transconjunctival orbital fat decompression surgery in patients with inactive thyroid-associated ophthalmopathy.

10 inactive patients with mild to serious thyroid-related ophthalmopathy were chosen for this review. Modified transconjunctival orbital fat decompression surgery was performed on the patients. The INFINITT device workstation was used to calculate the eyeball protrusion value based on the results of a spiral CT scan taken before and after surgery.

The standard elliptical vertebral volume formula was used to calculate the muscular cone inner volume. Changes in eyeball protrusion and the inner volume of the muscular cone before and after surgery were examined. Statistical analysis of the correlation between the two parameters was performed.

Results:
--Radiological measurement results confirmed that removing the orbital fat in the muscle cone during surgery was effective for alleviating eyeball protrusion in patients with thyroid-associated ophthalmopathy.

--This surgery caused an obvious change in the muscle cone inner volume.

--And there was significant correlation between changes in eyeball protrusion and muscle cone inner volume (r=0.797).

To summarize, the radiological evaluation approach used in this analysis is basic and straightforward. Updated orbital fat decompression surgery is an option for inactive patients with mild to extreme thyroid-associated ophthalmopathy who simply wants to improve their appearance.
