OBJECTIVE
To determine the prevalence of infraorbital ethmoid cells on panoramic radiographs. Infraorbital ethmoid (Haller's) cells are extensions of ethmoid air cells into the areas of the orbit and maxillary sinus and may be seen when present on panoramic radiographs.
STUDY DESIGN
In this retrospective study, 233 panoramic radiographs were examined for infraorbital ethmoid cells. A diagnostic criterion was developed to identify infraorbital ethmoid cells on panoramic radiographs.
RESULTS
Sixty panoramic radiographs were discarded because the orbital outline was not seen. Of the 173 panoramic radiographs, the prevalence of infraorbital ethmoid cells was 38.2% (30.8% for men and 40.3% for women).
CONCLUSIONS
The prevalence on panoramic radiographs was within the range of prevalence on CT examinations reported by others.
