Summary
A conservative endonasal microscopic decompression for thyroid-associated orbitopathy improves vision and reduces proptosis. This approach, preserving orbital tissues, yields similar results to aggressive resection but with a lower risk of new-onset double vision.
Area of Science:
- Ophthalmology
- Otorhinolaryngology
- Endocrinology
Background:
- Thyroid-associated orbitopathy (TAO) often requires surgical intervention when conservative treatments fail.
- Endonasal microscopic decompression is a surgical option for TAO, with varying techniques impacting outcomes.
Purpose of the Study:
- To compare two endonasal microscopic decompression techniques for TAO.
- To evaluate the efficacy and complication rates of conservative versus aggressive orbital decompression in TAO patients.
Main Methods:
- 35 TAO patients underwent endonasal microscopic bimural osteotomy.
- Group A: Periorbita resected, fat septa cut. Group B: Periorbital strips preserved, fat septa respected.
Main Results:
- Both techniques improved vision and reduced proptosis.
- The conservative approach (Group B) resulted in similar visual gain and proptosis reduction.
- Group B had a significantly lower incidence of de novo diplopia in primary gaze compared to Group A.
Conclusions:
- Conservative endonasal microscopic orbital decompression is effective for TAO.
- Preserving periorbital tissues and fat septa achieves comparable outcomes to aggressive resection with fewer complications, specifically new-onset diplopia.
- A multi-step rehabilitation approach for TAO includes orbital decompression, followed by strabismus surgery and eyelid repair if needed.
