[Significance of echographic tissue differentiation for orbital surgery].
The high degree of accuracy of standardized echography in tissue differentiation of orbital tumors enables the ophthalmic surgeon to determine exactly whether or not orbitotomy is indicated. As a result of the echographic examination the ophthalmologist is optimally informed as to the location, extent, delimitation and nature of the tissue of the tumor, and therefore better able to perform the orbitotomy. Standardized A-scan echography is capable of demonstrating an orbital tumor with 99% accuracy. Its location, limits, and tissue differentiation decide whether conservative or surgical treatment is to be preferred. Orbital tumors in any location can be removed by Krönlein's temporal orbitotomy: the wide temporal approach enables even large tumors to be excised in toto. With appropriate care much of the orbital contents can be spared and an optimal functional and cosmetic result achieved.
