Anatomical Study of Patients with MR Examination of Normal Temporomandibular Joint Discs
Objective To investigate anatomical characteristics and variations of normal temporomandibular joint discs by magnetic resonance(MR)examination,and provide reference for clinical diagnosis and treatment.Methods The paper chose 50 patients who with temporomandibular joint MR examination in a hospital from January 2022 to December 2022,measured and analyzed anatomical structures.Thickness of anterior,middle,and posterior bands of normal temporomandibular joint disc in open position was greater than closed position(P<0.05).Thickness of anterior and posterior bands in closed and open positions was greater than middle band,while thickness of posterior band in open position was greater than anterior band.There was no statistically significant difference between two in closed position(P>0.05).Length of articular disc in open position was greater than closed position(P<0.05).Conclusion Detailed understanding of anatomical features of temporomandibular joint disc through MR examination can improve accuracy and effect of diagnosis and treatment of temporomandibular joint related diseases.
