The morphological features of lateral pterygoid muscle (LPM) in normal position disk (NP) group, anterior disk displacement with reduction (ADDWR) group and anterior disk displacement without reduction (ADDWOR) group. The measurement of length (a), width (b) and thickness (c) of LPM. As the anterior disk displacement became more and more severe, (d, g, j) the length and (e, h, k) the width of LPM showed a tendency of decrease but the thickness of LPM (f, i, l) increased firstly and then decreased
