Description

Six cases of so-called maxillary sinus mucous retention cysts are reported here, focusing mainly on X-ray CT and rotational panoramic examinations. The originating wall and the CT number of the lesions are studied.<br>The results are as follows:<br>1. Alternate positioning of the patient in the CT examination seemed to present valuable information on the origin and the contents.<br>2. The probability of occurence seemed to be more than previously reported because three mucous retention cysts were found during CT examination.<br>3. Mucous retention cysts seem to originate from all of the walls of the maxillary sinus except the upper with equal probability.<br>4. According to the CT number, the mean value seemed to be around 80. There seemed to be a tendency for small mucous retention cysts to have a rather large CT number.<br>It is also reconfirmed that the CT examination seems to be valuable for diagnosing the diseases occuring on the maxillary sinus.
