چکیده
AIM To present the results of endonasal endoscopic orbital decompression in patients with Graves' ophthalmopathy. METHODS Endonasal endoscopic orbital decompression was performed in 32 orbits of 21 patients with Graves' ophthalmopathy. In 17 patients the surgery was performed because of active ophthalmopathy non-responsive to conservative treatment, and in 4 patients for esthetic reasons. Preoperative and postoperative examination included visual acuity, examination of the eyelids and cornea, ocular motility, cover testing, Hertel exophthalmometry, and applanation tonometry. RESULTS Visual acuity improved from preoperative 0.81+/-0.28 (mean +/- standard deviation) to postoperative 0.92+/-0.21 (p=0.0032, Student t-test). Retraction of upper and lower eyelids, as well as exposure keratitis, was reduced after operation (p<0.001). Mean proptosis reduction in all orbits was 4.6+/-1.7 mm (p<0.001). An average reduction of intraocular pressure was 3.4+/-3.0 mmHg (p<0.001). New-onset diplopia developed in 8 patients. Diplopia persisted in 9 out of 11 patients who had preoperative diplopia. Two patients experienced postoperative relief of diplopia. Ocular motility was subsequently corrected by eye muscle surgery in 13 eyes, whereas prisms were used in other 5 manifestly strabic eyes. CONCLUSIONS Endonasal endoscopic orbital decompression procedure improved visual acuity, decreased proptosis and intraocular pressure, and also had favorable cosmetic results in most patients. Post decompression diplopia and strabismus were successfully managed by either eye muscle surgery or application of prisms.

Endoscopic Orbital Decompression for Graves' Ophthalmopathy*
Background: In patients with Graves' ophthalmopathy, orbital decompression surgery is indicated for compressive optic neuropathy, severe corneal exposure, or for cosmetic deformity due to proptosis. Traditionally this has been performed through a transantral approach, but the associated complication rate is high. More recently, endoscopic orbital decompression has been performed successfully wi...
متن کاملEndoscopic orbital decompression for optic neuropathy in thyroid ophthalmopathy.
Optic neuropathy, an uncommon manifestation occurs in 5% of patients with Graves' ophthalmopathy. Its outcome is good if early and proper treatment given. We reported a 49 years old male patient of Graves' disease with bilateral optic neuropathy. He underwent bilateral transnasal endoscopic orbital decompression with marked improvement of visual acuity bilaterally. The preoperative visual acuit...
متن کاملEndoscopic orbital decompression for Graves' ophthalmopathy.
Graves' disease may occasionally result in significant proptosis that is either cosmetically unacceptable or causes visual loss. This has traditionally been managed surgically by external decompression of the orbital bony skeleton. Trans-nasal endoscopic orbital decompression is emerging as a new minimally-invasive technique, that avoids the need for cutaneous or gingival incisions. Decompressi...
متن کاملOriginal endoscopic orbital decompression of lateral wall through hairline approach for Graves’ ophthalmopathy: an innovation of balanced orbital decompression
Background Orbital decompression is an important surgical procedure for treatment of Graves' ophthalmopathy (GO), especially in women. It is reasonable for balanced orbital decompression of the lateral and medial wall. Various surgical approaches, including endoscopic transnasal surgery for medial wall and eye-side skin incision surgery for lateral wall, are being used nowadays, but many of the...
