Abstract

BACKGROUND AND OBJECTIVES: Exophthalmos from Graves' disease can result in visual disturbance and cosmetic deformity. Surgical treatment of this disorder is possible through a transnasal endoscopic approach or transantral approach. We aimed to evaluate the efficacy of the transnasal endoscopic orbital decompression and transantral orbital decompression in the management of dysthyroid orbitopathy.
MATERIALS AND METHODS
Transnasal endoscopic orbital decompression or transantral orbital decompression was performed on 25 orbits in 14 patients for treatment of progressive exophthalmos or visual loss. Transantral orbital decompression was performed on seven patients simultaneously.
RESULTS
Proptosis was reduced an average of 2.8 mm (range 0.5 to 6 mm) by transnasal endoscopic decompression alone and of 3.5 mm (range 0.5 to 8 mm) by transnasal endoscopic decompression and transantral decompression. In five patients who complained of visual disturbance, visual acuity was improved in three of them, and stationary in two of them postoperatively. Four patients who had no diplopia preoperatively developed diplopia after the decompression. Among them the diplopia was only temporary in three patients and the remaining one was referred to an ophthalmologist for correction of persistent diplopia.
CONCLUSION
Orbital decomprerssion can be performed successfully via the transantral and transnasal endoscopic approach without significant complications and external scar.
