ABSTRACT

Objectives: The Purpose Of The Study Was To Assess The Relation Between Clinical And Magnetic Resonance Imaging Findings In Temporomandibular Joint Disorders.

Materials and Methods: MRI Scanning And Clinical Examination Were Performed To Twenty Patients Of Both Sexes And Varying Ages, Complaining Of TMJ Disorders. The Disc Position, Disc Morphology, Condylar Osseous Changes, Retrodiscal Tissue Status And Joint Effusion Were Assessed. The Correlation Between The Clinical And MRI Findings Was Statistically Analyzed.

Results: Pain In The Temporomandibular Region Was The Most Common Clinical Presentation, It Accounts For 67.5% Of Cases. Significant Correlation Was Found Between Pain And Disk Morphology, Condylar Osseous Changes, Retrodiscal Tissue Status (p=0.001, 0.019, 0.003 Respectively)and With Disc Displacement. Statistically Significant Relationship Was Also Found Between Disk Position, Eminence Changes And TMJ Sounds (P=0.025, 0.004 Respectively), As Well As Between Disk Position And Maximum Mouth Opening (MMO)( P=0.018). There Was A Direct Correlation Between Retrodiscal Tissue Status And Mandibular Deviation (p=0.021). Conclusion: Clinical Evaluation Of The TMJ Can Be Nonspecific Due To Overlap Of Symptoms Between Internal Derangement And Myofacial Pain Dysfunction. MRI Should Be Part Of The Standard Evaluation When An Internal Structural Joint Abnormality Is Suspected .Disc Displacement As Observed With MRI Correlated Well With Clinical Signs And Symptoms.
