title: Zygomatic air cell defect: A panoramic radiographic study of a south Indian population.
abstract: OBJECTIVE
  To determine the prevalence, patterns of occurrence and variations of zygomatic air cell defects (ZACDs) using panoramic radiographs.
  
  
  METHODS
  Dental panoramic radiographs of 600 outpatients were examined to evaluate the variations and characteristics of ZACDs.
  
  
  RESULTS
  ZACDs were identified in 15 subjects out of 600, giving an overall prevalence of 2.5%. Seven ZACDs were seen in males and eight in females. Among the 15 ZACDs, nine were unilateral and six were bilateral.
  
  
  CONCLUSIONS
  The overall prevalence of ZACD is relatively low in south Indian population and careful radiographic evaluation is needed to detect these entities.
