[Radiographic findings of the so-called globulomaxillary cyst].

Abstract

In definite diagnosis of this cyst, it is deemed that a comprehensive diagnosis is required including operative findings upon its extraction and the pathohistological findings of the extracted matter in addition to the radiographic and clinical findings, such as one that the region of development is between the maxillary lateral incisor and the cuspid, one that the adjacent teeth are vital ones, etc. Thus, we examined 10 cases that we had defined as the subjects of so-called Globulomaxillary cyst by clinical and pathohistological findings in terms of the developmental region, size, border, etc. As a result, the following things turned out: 1. The median positions of cystic development existed 8 cases in left side and 2 cases in right side out of 10 cases. And this median positions could be divided into those between the central incisor and the lateral incisor (5 cases) and those between the lateral incisor and the cuspid (5 cases). 2. The pathohistological findings led to the following classification; 2 cases with no inflammation, 5 cases with inflammation, and 3 cases with present inflammation in the past. The border line of cyst on radiographic findings tended to be relatively unclear in the cases with inflammation in the past.
