Abstract
We had a rare case which both maxillary sinuses communicated with each other.The patient, a Japanese housewife, 26 years of age, complained of increased swelling of both cheek region since 4 months prior to first visit to the clinic.
Following X-ray examination with the method of Moljodol instillment the operation was performed, and we found that there was a canal in the alveolar process communicated to both maxillary sinuses.The canal was in size of little finger tip, and covered by mucous membrane which continued to those of maxillary sinuses.
