Endoscopic orbital decompression for Graves' ophthalmopathy

Area of Science:

• Ophthalmology
• Otorhinolaryngology
• Surgical Innovation

Background:

• Graves' ophthalmopathy causes orbital volume excess, leading to proptosis, pain, diplopia, and optic neuropathy.
• Endoscopic orbital decompression expands the orbital cavity into adjacent sinuses.
• This study evaluates outcomes of this surgical approach for Graves' ophthalmopathy.

Purpose of the Study:

• To assess the safety, efficiency, and efficacy of endoscopic orbital decompression.
• To document patient outcomes including symptom resolution and proptosis reduction.
• To identify complications and the need for subsequent procedures.

Main Methods:

• Retrospective review of 62 patients undergoing endoscopic orbital decompression (July 1989 - April 2003).
• Data collected: demographics, symptom resolution, complications, proptosis reduction, need for eye muscle surgery, and length of stay.
• Analysis of outcomes for unilateral and bilateral Graves' ophthalmopathy.

Main Results:

• 70% of patients were women, average age 49. Preoperative diplopia in 63%, optic neuropathy in 27%.
• Average proptosis reduction of 2.5 mm. 25% did not require eye muscle surgery; 48% needed one procedure for diplopia.
• Two cases of cerebrospinal fluid leak managed intraoperatively; no postoperative leaks. High outpatient or short-stay management.

Conclusions:

• Endoscopic orbital decompression is a safe, efficient, and effective procedure for Graves' ophthalmopathy.
• The technique successfully reduces proptosis and addresses related symptoms.
• Eye muscle surgery remains frequently necessary for managing post-decompression diplopia.
