An Irrefutable Unambiguous Insights Into Zygomatic Air Cell Defect (Zacd)

Abstract

Abstract PURPOSE Zygomatic air cell defect of temporal bone, have been characterized as the auxiliary air cells in the zygomatic process and articular eminence of the temporal bone. They present as unresectable findings in the zygomatic process of the temporal bone and articular tubercle and is crucial as they signify regions of weak resistance and the spread of disease. Comprehension about the decrepit regions in the Zygomatic bones with CBCT, the imaging of choice in maxillofacial disorders for its superior 3D anatomical reconstruction and minimal distortion, is indispensable in the diagnosis, treatment planning and placement of Endosseous or Basal Dental implants to elude complications. METHOD 154 CBCT images of subjects aged 18 to 70 years with optimal diagnostic quality and area coverage satisfying the selection criteria without the history of maxillofacial fractures, pathologies, anomalies involving the middle one third of the face were analysed. RESULTS The overall prevalence of ZACD was in 16 (10.4%) subjects with 9 in females (56.25%) and in 7 males (43.75%). The men to women ratio was 1:1.28. It was also revealed that bilateral incidence of ZACD was more common and the prevalence of ZACD the highest 8 (50%) in the age group of 21 -30 yrs. CONCLUSION This study highlights the importance of research on the prevalence of the ZACD on CBCT which were exiguous in the pastand compares with similar studies done using panoramic radiographs and pave a way for more studies employing CBCT to justify the findings we have expressed.
