측두하악관절부위에 발생하는 양성 외방성 증식은 골종, 연골종, 골연골종 및 활액성 연골종증 등이 있으며 증상으로는 통증, 개구제한 등을 보이며 때때로 교합변화 하악정중선변위등을 수반한다. 이러한 양성 외방성 증식은 측두하악장애와 비슷한 증상으로 인해 임상 증상만으로 진단 하는 것은 어려우며, 단층촬영, 자기공명영상을 포함한 방사선 사진을 평가하여야 하며, 확진을 위해서는 생검을 필요로 한다. 활액성 연골종증과 골연골증은 인체의 장골에 흔한 양성 종양이며 구강안면부위에 있어 발생이 비교적 드물다. 본 연구는 측두하악관절에 비교적 드물게 발생하는 활액성 연골종증과 골연골종에 대하여 보고하고 진단에 대해 다소의 지견을 얻었기에 문헌 고찰과 함께 보고하고자 한다.

악관절부위의 활액성 연골종증은 매우 드물기 때문에 확진하기 까지 종종 몇 개월 몇 년이 걸리도 한다. 활액성 연골종증은 드문 양성 병소로 활액 내 수 많은 연골성, 골연골성 결정과 관절강내의 소성체가 형성되는 질환으로 관절강 내에 소성체를 형성하는 활액막의 연골성 변성으로 정의할 수 있다. 본 증례에서 29세 여자 환자로 저작시 동통을 주소로 내원하였다. 방사선 소견상 상관절강내에 석회화된 소성체가 발견이 되었다 치료는 석회된 소성체와 활액막 일부를 제거하였다. 술 후에 환자의 저작시의 동통이 완전히 사라졌다. 현재 아무런 재발 증상을 보이지 않고 있다.

Synovial chondromatosis is an uncommon disease of cartilage transformation of synovial membrane with formation of loose bodies within the joint space. The involvement of temporomandibular joint is very rare. Symtoms include swelling, pain, stiffness of the jaw, and inability to close the jaw. A case involving the temporomandibular joint(TMJ) and non-symptoms is presented.

Synovial condromatosis of the temporomandibular joint (TMJ) is characterized by the presence of loose bodies (joint mices). It can be confused with temporomandibular disorder clinically, and be with chondrosarcoma histologically. The purpose of this clinical report was to review the clinical, radiological, arthroscopic findings, histological feature and the results of surgical treatment of TMJ synovial chondromatosis. Four patients presented with pain of TMJ and limited mouth opening. The dynamic magnetic resonance imaging (MRI) disclosed a characteristic morphologic changes and displacement of the meniscus with limited translation of the condyle head. Bone scans showed progressive resorptive changes with hot-uptake of the radioisotope. The synovial loose bodies in the joint spaces were removed and sent to pathology for diagnosis as the synovial chondromatosis. The follow-up examination with computed tomography (CT) and MRI revealed no evidence of recurrence and good in function until postoperative 18 months. Diagnostically, the distension of the lateral capsule and fluid findings in the joint on the MRI are very suggestive tool for this synovial chondromatosis, but they are not always detected on the preoperative MRI. Arthroscopic approaches are very useful to inspect the joint spaces and to remove the loose bodies without interruption of the whole synovial membranes.

Synovial chondromatosis is an uncommon disease of cartilage transformation of synovial membrane with formation of loose bodies within the joint space. The knee and elbow are the most commonly involved sites and involvement of temporomandibular joint is very rare. Symtoms include swelling, pain, stiffness of the jaw, and inability to close the jaw. A case involving the temporomandibular joint(TMJ) is presented. A 28-year-old women had experienced pain of the left TMJ area and limitation of mouth opening. Radiographs of the left TMJ revealed calcified mass surrounding over the mandibular condyle and under the glenoid fossa. Treatment consisted of removal of calcified mass, reshaping of affected condyle and reconstruction with a auricular cartilage. After surgery, the patient's range of motion improved although deviation to the affected side. Until present after surgery there have been no recurrence of symtoms. We think that findings of this patitent agree with those of synovial synchondrmatosis in many aspects.
