The clinical reliability and effectiveness of the postero-anterior cephalometric view, submentovertex view, and panoramic view in the diagnosis if the facial asymmetry

Clinical examination, photometric evaluation, and radiographic analysis have been used to evaluate the asymmetry of the face. Commonly used skull radiographs to assess skeletal asymmetry include postero-anterior cephalometrics, submentovertex view, and panoramic view. The purpose of this study is the comparison of the reliance of the postero-anterior cephalometric view, submentovertex view, and panoramic view in the asymmetric group. The measurements are MSL (midsagittal plane)-Co, MSL-Go, MSK-Me, MSL-Al, MSL-Bl, Mn. ramus Height (Co-Go), Mn. Body Length (Go-Me), and Total Mn. Length (Co-Mr). The results were as follows: 1. The lack of either a right-sided of left-sided asymmetric dominant was found. 2. The postero-anterior cephalometric view and submentovertex view relatively agreed with each other in the result. The postero-anterior cephalometric view and submentovertex view had the clinical reliability and effectiveness in the diagnosis of the skeletal asymmetry (p<0,05).3. The panoramic view showed more magnification compared to the other radiographs. In the vertical measurements the panoramic view had clinical reliability relatively (p<0.05). But we cannot rely on the horizontal measurements in the panoramic view (p<0.05).
