A computer program for planimetric analysis of digitized images.

Planimetrical measurements are made to calculate the area of an entity. By digitizing the entity the planimetrical measurements may be done by computer. This computer program was developed in conjunction with a research project involving measurement of the pneumatized cell system of the temporal bones as seen on X-rays. By placing the X-rays on a digitizer tablet and tracing the outline of the cell system, the area was calculated by the program. The calculated data and traced images could be stored and printed. The program is written in BASIC; necessary hardware is an IBM-compatible personal computer, a digitizer tablet and a printer.

CT-scanning of ancient Greenlandic Inuit temporal bones.

Additional morphological evidence of former infectious middle ear disease (IMED) was found by CT-scanning in 5 of 6 Greenlandic Inuit crania strongly suspected for former IMED due to earlier examination revealing either bilateral hypocellularity or asymmetry of the pneumatized area of the temporal bones. The CT-scans showed sclerosing and obliteration of the air cells and even destruction of the cellular septae, and a high degree of irregularity of the cells. Sclerosing of the surrounding bone tissue was also found. The findings in one cranium were dubious and could both be regarded as a congenital malformation or an infection in infanthood. CT-scan confirms and even adds to the results of conventional X-ray of temporal bones making hypotheses of paleopathology more reliable. The findings also support the environmental theory of pneumatization of the air cell system in the temporal bones.

Pneumatization of the temporal bones in a Greenlandic Inuit anthropological material.

The degree of pneumatization of the temporal bones correlates with exposure during childhood and adolescence to infectious middle ear diseases (IMED), both acute and chronic. The pneumatized area as seen on cranial X-rays can be measured. This was applied to an anthropological material in order to develop methods for assessing ancient populations' exposure to IMED. Fifty-six Greenlandic Inuit (Eskimo) crania were examined. The crania were sexed and measured. X-rays were taken bilaterally, using the projection of Runström II, and the pneumatized area was measured planimetrically by computer. In blind trials it was found that the inter- and intraobserver variation was non-significant; that the degree of pneumatization of the temporal ossa did not reflect cranial size or sexual dimorphism; and that the pneumatized areas correlated bilaterally. Asymmetry in the size of the pneumatized areas, an indicator of exposure to IMED, was found in 5 crania (9%).
