A radiographical classification of Stafne's bone cavity

So-called Stafne's bone cavity of the mandible were detected by panoramic radiography in 24 patients seen at the Second Department of Oral and Maxillofacial Surgery, Meikai University Hospital, and five associated hospitals. Unilateral and asymptomatic, all lesions were situated near the angle of the mandible, except for the one case that involved the anterior portion of the mandible. The mean age of the patients was 53 years with a range of 31 to 78 years, and included 22 men and 2 women. In this report, radiographic interpretation of the lesion was done, and a radiographic classification was made as follows:

1. (Indentation type): The inferior border of the mandible is involved.
2. (Medium type): The lesion is situated above the inferior border of the mandible but below the mandibular canal.
3. (Deviation type): Deviation of the mandibular canal is suspected.
4. (Anterior type): The radiolucency is located in the anterior portion of the mandible.
