A Case of Transnasal Endoscopic Orbital Decompression in Grave's Ophthalmopathy

  • 1Department of Otolaryngology, Joongang Gil Hospital, Seoul, Korea.


Grave's disease is an autoimmune disorder and affects thyroid gland and orbit. Ocular manifestations of this disease, referred to as Grave's ophthalmopathy are caused by deposition of antithyroglobulin immune complexes into extraocular muscles and orbital fats. Consequent increase in volume of orbital contents results in exopthalmos. Severe exopthalmos results in several significant visual consequences as follows: exposure keratitis, diplopia and optic neuropathy. Orbital decompression for Grave's ophthalmopathy has traditionally been performed through either an external or a transantral approach. The advent of intranasal endoscopes allowed for the development of a transnasal approach for medial and inferior orbital wall decompression. Recently, the authors experienced a case of Grave's ophthalmopathy complicated with exposure keratitis and performed endoscopic transnasal orbital decompression, so report this case with a review of literature.
