Static bone cavities were first described by Stafne in 1942 as cystic bone cavities situated near the angle of the mandible on roentgenogram. The contents of this lesion confirmed in surgery were salivary gland tissues, connective tissues, veins, nerves, fatty tissues and lymphnode tissues. The etiology of this lesion is not established yet. Salivary gland tissues were most found in this lesion and it seems that the cavity is significantly related with salivary gland.
We report here the results of investigation and some discussions on the static bone cavity which was diagnosed by sialography.
The subject was a 69-year-old woman. She appeared at our clinic on 5/16/86, having been referred to us by her general dentist with X-ray findings showing radiolucent and nonradiolucent lesions of the mandible. We thought that radiolucent lesion was a static bone cavity and performed sialography. Sialogram of the submandibular salivary gland showed that some part of the gland was in the radiolucent region of the bone defect. We found the significant relation with the submandibular salivary gland, which lead us to render the diagnosis in this case. We did not perform any surgery but merely observed progress.
