This study was performed to evaluate the role of Waters' view and panoramic view
for the interpretation of mucosal cyst of the maxillary sinus and to determine the
radiographic features of that according to the sites and sizes.
For this study, clinically 25 cases of mucosal cyst of the maxillary sinus were used,
and experimentally with two dry skulls, rubber ball of 15mm in diameter for marked
radiopacity, and two jelly balls of 8 and 20 mm in diameter for the similar radiopacity
to cyst were used.
The 25 cases with 25 panoramic views and 15 Waters' views were first analysed, and
secondly, the radiographic features of artificial lesions attached to the each wall o( the
antrum on Waters' view and panoramic view were analyzed.
The obtained results were as follows.
At clinical analysis,
1. 4 cases of 13-14§®, 4 cases of 15-19§®, 14 cases of 20-25§® 3 cases of over 30§®
in diameter were found on panoramic views. And 24 cases of 25 cases showed no
relationship with teeth, and only 1 case was associated with advanced periodontal
disease
2. The majority of mucosal cysts appeared to arise the posterior portion of the floor
of the sinus and were superimposed with the inominate line of zygoma and the
horizontally linear image of hard palate on panoramic view.
3. Only 2 cases of 15 cases were identified on both films.
At experimental analysis,
4. On Waters' view, the images of the artificial lesion of the anterior portion and
midportion of the floor of the sinus were lessend in diameter compared with the real
size. On panoramic views, the images of the lesion were more radiolucent with lessened
diameter than images on Water' view.
5. The images of the lesion of the posterior wall and the posterior portion of the floor
of sinus on panoramic view were well detected by the preeducated group but not or
poorly detected by the non-preeducated observer group.
6. On Waters' view, both observer groups recognized that the cystic images of the
posterior portion of the floor of the maxillary sinus were superimposed with the petrous
portion of the skull.
