中文摘要 | 放射線檢查一直是診斷顳顎關節疾病之重要工具。它包含了斷層攝影、環口攝影 術、電腦斷層掃描等方法。而三維空間電腦斷層攝影術則是一門近幾年才發展的新技術,其 方法是將平面電腦斷層掃描影像的數據資料,以電腦重組成模擬原物狀之影像。本文報告一 例因外傷造成顳顎關節粘連之患者,因張口不全前來本院求診。經此技術檢查後可清楚發現 其關節粘連障礙主要是在單側而非一般常規攝影所呈現之兩側。患者在接受以肋骨移植之關 節置換術後,張口運動獲得明顯改善。由此可看出,三維空間電腦斷層攝影術在診斷顳顎關 節粘連疾病方面,相對於其它傳統放射線檢查有明顯的優勢。 |
英文摘要 | Roentgenographic examination has long been a useful diagnostic tool for temporo-mandibular joint (TMJ) disease. The methods include TMJ tomography, panoramic radiography and computerized tomography (CT) scan with or without injection of contrast media. Recently, three-dimensional CT (3D-CT), reconstructed from the two-dimensional image of a CT scan to simulate the soft tissue or bony structure of the real target, was proposed. In this report, a case of TMJ ankylosis due to traumatic injury is presented. 3D-CT was employed as one of the presurgical roentgenographic diagnostic tools. The conventional radiographic examination including panoramic radiography and tomography showed lesions in both sides of the mandible. CT scanning further suggested that the right-sided lesion was more severe than that on the left. With 3D-CT image reconstruction the size and extent of the lesions were clearly observable. The decision was made to proceed with an initial surgical approach on the right side. With condylectomy and condylar replacement using an autogenous costochondral graft on the right side, the range of mouth opening improved significantly. In this case report, 3D-CT demonstrates its advantages as a tool for the correct and precise diagnosis of TMJ ankylosis. |
