Paleopathological evidence of paranasal lesions: Two cases of frontal sinus osteomata from Imperial Rome

Abstract

The archaeological excavations carried out in 1999 in the Collatina necropolis of the Roman Imperial Age (1st-3rd centuries AD) (Rome, Italy) discovered the skeletal remains of two adult males with evidence of paranasal lesions. Both individuals showed postmortem damage in the frontal bone, through which it was possible to macroscopically detect an oblong new bone formation. In both specimens, radiological examination of the defects' morphology showed new pediculated-based bone formations. Radiology also confirmed the presence of benign osseous masses arising from the right frontal sinus and interpreted as osteomata. Their dimensions did not exceed 10 mm, so that mechanical complications and compression of the adjacent structures could be ruled out. The osteomata of paranasal sinuses are rarely reported in paleopathology, since they can be discovered only incidental to bone breakage or radiography. Hence, the evaluation of their occurrence in past populations represents an important challenge. The two cases presented here show direct and rare evidence of frontal sinus osteomata dating back to the Roman Imperial Age.
