The authors present the endoscopic intranasal orbital decompression, one of the surgical techniques used for orbital decompression. It can be applied for various indications. The most common indications are: maxillo-facial trauma, orbital haemorrhage, subperiorbital abscess as the complication of sinusitis, optic neuropathy, thyroid-associated orbitopathy (Graves’ orbitopathy). The authors conclude that the endoscopic transnasal orbital decompression is a valuable and safe operational technique for patients requiring orbital decompression.
