[Endonasal endoscopic orbital decompression through the transethmoidal approach].

The paper is designed to discuss the possibilities for the extension of indications to endonasal endoscopic surgery. Original experience with the surgical treatment of endocrine ophthalmopathy in patients with pharmacologically compensated thyroid dysfunction and clinical manifestations of exophthalmus is presented. A total of 6 operations were made through the transethmoidal approach with the resection of medial and inferior orbital walls. Regression of exophthalmus from 3.5 to 6 mm was achieved in 5 patients. Postoperative diplopia was documented in two patients within 3 weeks after surgery. Five patients enjoyed improvement of vision and quality of life due to correction of the cosmetic eye defect. None of the patients developed purulent complications affecting orbital tissues and paranasal sinuses. Surgical techniques and peculiarities of postoperative patient care are discussed.
