Role of radiography in the diagnosis of mucoceles.

The role of radiography is of the utmost importance in the diagnosis of mucoceles. The use of plain films and tomograms enabled us to make the exact diagnosis of mucocele 19 out of 26 times. The patients had a mechanical proptosis, one sinus with a subnormal transparency was enlarged, and its walls were either thinned or broken at the place of a structural process of alteration. Orbital venography shows the venous shifting and ascertains the posterior extension and the extra-conal location of the tumour.
