This is a clinico-statistical study of 97 inpatients with maxillary antrum-related lesions with exception of traumas and malignant tumors in this hospital during the past 10 years.

The results were as follows : 1) Most of the 97 cases were postoperative maxillary cysts (44 cases : 46%) or odontogenic maxillary sinusitis (34 cases : 35%). 2) 74 cases (76%) of the 97 were referred from the other dental or medical clinics to the hospital. 3) The average periods of the treatment till the patients with postoperative maxillary cysts visited to our hospital were 48 days and for odontogenic sinusitis it was 89 days, respectively. 4) The treatments for these two lesions before consultation with us were mostly antibiotic therapy and/or root canal treatment. 5) These results suggest the necessity of tight affiliation between primary medical facilities and secondary or tertiary medical facilities in investigation of maxillary antrum-related lesions too
