Objectives:
This research involved retrospectively evaluating panoramic radiographs of patients from India with the intention of assessing the prevalence of Zygomatic Air Cell Defect (ZACD) and establishing its dominant location and type.
Methods:
Seven thousand seven hundred and fifty-five panoramic radiographs of routine outpatients aged between 19 and 91 years were concomitantly evaluated by four investigators for estimating the prevalence and characteristics of the Zygomatic Air Cell Defect.
Results:
The prevalence of ZACD was noted to be 1.82%, with male preponderance. Unilateralality and multilocular appearance of ZACD were the dominant patterns observed.
Conclusion:
The frequency of ZACD amongst Indian population is in harmony with most of the similar studies conducted on various geographic populations.
