Purpose: To evaluate the effects of the three-wall decompression technique using transpalpebral and endonasal approach inpatients suffering from Graves' ophthalmopathy.Methods: In this prospective study, we present a consecutive series of 15 subjects (17 eyes) who were submitted to orbital decompression by removing the inferior and lateral walls using transpalpebral incision combined with a, transnasal endoscopic resection of the medial wall. The surgical technique involved the preservation of the bone structure between the lamina papyracea of the ethmoid and the maxillary orbital floor.Main results: The mean ocular recession based on Hertel measurements was 6 00 mm (range, 4-9 mm). None of the patients presented pre-operation diplopia, and one developed post-operation diplopia. Visual acuity was preserved in all cases.Conclusion: It is safe and efficient to perform three-wall decompression, combining transpalpebral and endoscopic transnasal, approach, with preservation of the bone structure and the bone lateral to the infraorbital canal with fixation by two titanium plates on the lateral edge and removal of intraorbital fat, which results in significant proptosis reduction and minimal complications.
