摘要

就關節功能而言：顳顎關節（T MJ）為身體上重要關節之一，在目前醫學發達，儀器進步和技術上，對於關節內之硬的或軟的組織皆能從放射線檢查加以評估和診斷。有關顳顎關節之放射線檢查工具有普通X光素片，局部放射線檢查法，三度空間電腦斷層造影，關節造影檢查和磁振造影檢查。由於關節攝影檢查對顳顎關節內錯位功能的診斷非常有用，所以常被用來診斷顳顎關節內錯位情形和功能之工具。由於磁振造影檢查具有高度解析能力，尤其對軟組織構造可做多方向之切面，非侵犯性且不具放射線之檢查工具對顳顎關節內錯位之評估與診斷非常有用，最近常被用來診此關節之內錯位情形，逐漸取代其它檢查之趨勢。台中榮民總醫院從民國七十八年十二月至八十年六月止，共收集了十六例顳顎關節不適，其年齡從二十三歲至六十七歲，男性有十例，女性有六例。其主要臨床徵狀為顳顎關節疼痛，卡塔地響（clicking），咀嚼和講話困難及嘴張開不易等。這些病人皆接受顳顎關節檢查，結果發現正常有二例，回復性關節板前異位者（Ani. displacement of disc with reduction）有八例，不可回復性關節板前異位者（Ant. displacement of disc without reduction）有三例，退化性下頷骨結節有三例。以上就我們所收集之病例加以整理分析，希望提供我們的經驗為臨床醫師在治療上有所幫助和解決問題之所在。

Sixteen temporomandibular joints (TMJ) were examined by a high resolution magnetic resonance (MR) imager. Multisection 3.5 mm thick sagittal and coronal images were obtained by 1.0-T MR system and spin-echo sequence (TR = 800 msec, TE 20 msec). MR provided useful information about meniscal position, morphology and histology. In our study, the MR of the 16 TMJ showed normal finding in two cases and abnormal findings could be differentiated into anterior disc displacement with reduction (8 cases), anterior disc displacement without reduction (3 cases) and bony change (3 cases). MR imaging can produce high-quality tomographic images with good demonstration of the internal structures of TMJ. As it is a noninvasive technique involving no ionizing radiation, MR imaging has been shown to be a useful tool for the demonstration of internal changes in TMJ.
