Orbital and periorbital tumors constitute 34% of this series, inflammatory diseases including thyroid disorders 50%, arteriovenous abnormalities 4%, and miscellaneous disorders 12%. All patients were thoroughly evaluated clinically and with appropriate diagnostic tests, including ultrasonography (combined A-scan and B-scan), computerized axial tomography (EMI cranial scan), and radiographic tech­ niques (plain films and hypocycloidal poly tomography), orbital venography, and carotid arteriography. Each test was found to have diagnostic capabil­ ities which complemented other studies, depending upon the specific disease process involved. No one test was entirely adequate without the others. Radiographic studies demonstrated bony abnormality in 50% of tumor cases, but in only 28% of the entire series of exophthalmos cases. Primary orbital tumors had a lower hield with radiography than did secondary tumors. Computerized tomography demonstrated diagnostic soft tissue abnormality in 86% of tumors, 43% of inflammatory diseases, and an overall yield of 62% positive results. Ultrasonography proved the most versatile test for evaluation of orbital soft tissues, with 80% positive results for tumors, 87% for inflammatory disorders, and 78% overall acurate diagnosis.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9789400999800\"\u003e\u003ch3\u003e1st edition\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9789400999800","offer_id":39454299521117,"sku":"9789400999800","price":53.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d1d2ca93-fd8b-48af-9d38-a61455ecf095.jpg?v=1760507447","url":"https:\/\/shop.autorenwelt.de\/products\/proceedings-of-the-3rd-international-symposium-on-orbital-disorders-amsterdam-september-5-7-1977-1st-edition-von-g-m-bleeker-hrsg","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
