안구돌출증 교정을 위한 Transantral Orbital Decompression후 발생한 지연성 급성 상악동염

Graves’ disease most commonly affects the thyroid gland and orbit. The ocular manifestations of this disease, referred to as dysthyroid orbitopathy, can have both cosmetic and visual threatening consequences. Surgical decompression of the orbit is performed by removing one to four bony walls. The confined orbital contents prolapse into adjacent spaces, allowing ocular recession with a reduction of pressure on the globe and optic nerve. The authors experienced an unusual case of delayed type acute maxillary sinusitis with infraorbital nerve palsy secondary to orbital decompression for Graves’ disease. That was due to obstruction of natural ostium by prolapsed orbital contents. We had a good result by ventilation procedure for maxillary sinus through endoscopic approach.
