Many techniques of orbital decompression have been used in the treatment of Graves ophthalmopathy. Recently endonasal endoscope surgery was introduced in the orbital decompression, as an isolated technique, or combined with existing techniques hopefully to give better visualization of medial wall and a lower incidence infection when the medial wall is acessed. AIM: To evaluate orbital decompression combined with endoscope in prevention of bacterial infection, we relate three cases of assyntomatic patients with computer tomography control of facial sinus presenting opacification of maxillary or frontal sinus. STUDY DESIGN: Clinical Prospective. MATERIAL AND METHOD: 16 patients with 18 orbita procedures underwent orbital decompression, in the Ophthalmology Department at the Escola Paulista de Medicina-UNIFESP an orbital decompression was obtained by combined technique using endonasal access with an endoscope. RESULTS: Four patients during postoperative CT scan presented assymtomatic opacification of the maxillary or frontal sinuses. CONCLUSION: A combination of endoscopy in orbital decompression by external approach showed the effectiveness in prevention of sinusitis clinically manifested and its complications, although a longer time of follow-up is needed to understand better radiological findings 22% presented opacification of the sinuses and their consequences.
