  • Abstract
  • Look Inside

Fifty-four cases of postoperative maxillary muco-celes were investigated using A- and B-mode ultra-sonography, CT and MRI.

The characteristic images by the B-mode ultra-sonography are as follows:

1) irregularity of defect at the anterior sinus wall

2) scar echo at the anterior sinus wall

3) oval-shaped cystic wall

4) homogenous by an abscent or low echo in the content

5) posterior cyst wall at the depth of 40~50 mm from the skin surface

6) enhanced posterior echo

The correct diagnosis as to the presence of mucoceles was obtained in 93% by the B-mode ultrasonography. And the correct diagnosis for single mucocele was 77%, and for multiple mucoceles, 38%.
