  • Purpose: The purpose of this study is to prove that orthognatic surgery on asymmetric prognathism patients improve the temporomandibular dysfunction. Materials and methods: All 30 patients underwent mandibular setback with B-SSRO including 22 patients Le Fort I surgery in KyungHee medical center. Preoperative and postoperative PA cephalograms & transcranial radiographs were measured midline deviation in Mx and Mn, occlusal canting change, condyle position, the temporomandibular dysfunction were checked before surgery, within 1 month after surgery, $3{\sim}6$ months, 12-24 months after surgery respectively. Results: The temporomandibular dysfunction were relieved after surgery in 17 patients of 25 patients. Conclusion: Orthognatic surgery may benefit the temporomandibular joint dysfunction in facial asymmetry patients by obtaining a postoperative stable occlusion and better physiologic neuromuscular function. Specially impovement of occlusal canting may reduce condyle displacement of midline deviation side and the temporomandibular joint dysfunction.

  • Recently, clinical efficacies of the intraoral balancing appliance therapy have been reported by several researchers, and it has been found that there are various kinds of diseases that can be effectively applied. However, studies on cerebrovascular disease, one of the main diseases with a high mortality rate, are still poorly reported, and studies of temporomandibular joint disorder (TMD)-induced changes in brain function suggest that cerebrovascular disease is more appropriate as an adaptive disorder of the temporomandibular joint (TMJ) balancing device. In the developed countries, the importance of research on the structure and function of the brain has been recognized and spurred on the related research. In Korea, the research on brain function and cognitive disorders should have promoted more massively. In order to regain its former reputation in the Korean medicine in the field of cerebrovascular disease, it should be spurred on basic research and clinical case studies. In addition, extensive and in-depth studies including animal studies are needed to establish the basis of underlying mechanisms of the TMJ balancing therapies.

  • The literature on alloplastic total temporomandibular joint (TMJ) replacement is encouraging, with acceptable improvement of treatment outcomes in terms of both pain level and jaw function. This is a case report on patients who suffered from degenerative joint disease and ankylosis after mandibular condyle fracture or prior TMJ surgery and were treated by TMJ replacement with condyle prosthesis. We obtained good results from the procedures, including total TMJ replacement.

  • 측두하악관절을 진단하기 위하여 선택할 수 있는 촬영 방법은 매우 다양하며, 모든 촬영법에는 제각각 장단점이 있으므로 모든 조건을 동시에 만족시키는 이상적인 하나의 촬영법은 없다. 그러므로 측두하악관절을 평가하기 위해서는 각 촬영법의 장단점을 파악하고 적절한 촬영법을 선택하여 다각적으로 분석해야 한다.

  • Temporomandibular disorders have been defined as a collective term embracing a number of clinical problems that involve the temporomandibular joint, the masticatory muscles, and associated structures. Since Dr. James Costen has mentioned about the relationship between TMD and posterior bite collapse, there have been many controversies about the etiology and comorbidities of TMD. The purpose of this study was to investigate the relationship between TMD and hearing acuity in 158 volunteers with or without TMD symptoms. The subjects were examined clinically about TMJ sound, missing teeth, tinnitus, TMJ pain and masticatory muscle pain and the hearing acuity were measured by Audiometer(ITO AE-1000, Japan). The result of this study indicated that there was no significant differences between TMD symptoms and hearing acuity relatively.

  • 다른 근골격성 질환에서와 같이, 측두하악장애의 징후와 증상은 일시적이거나 자기 한정적(self-limiting)인 경우가 많다. 따라서 복잡한 교합 치료나 수술과 같은 비보존적, 비가역적 치료를 초기치료로 선택하는 것은 가급적 피해야 한다. 또한 자가요법, 행동 수정, 물리치료, 약물요법, 장치치료 등과 같은 보존적, 가역적 치료가 측두하악장애의 초기치료로 추천된다.

  • Williams-Beuren syndrome (WS) is a rare genetic disorder that results from microdeletion at chromosome 7, which harbors the elastin gene. Clinical findings include arteriopathy, aortic stenosis, hypertension, and laxities and contractures in different joints throughout the body. While many components of the temporomandibular joint (TMJ) normally contain elastin, there are few reports on TMJ manifestations of WS. This study reports a TMJ ankylosis case in a WS patient and shares insight on a possible link between development of TMJ ankylosis and elastin deficiency in WS patients. A WS patient presented with bilateral TMJ ankylosis and was successfully treated with TMJ gap arthroplasty. Hypermobility of TMJ and lack of elastin in retrodiscal tissue can induce anterior disc displacement without reduction. Due to lack of elastin, which has a significant role in the compensatory and reparatory mechanism of TMJ, WS patients might be prone to TMJ ankylosis.

  • 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.

  • Introduction : Patients with temporomandibular disorder may have various ear-related symptoms. If an excessive load is applied to the ear area due to the skeletal shape of the mandibular condyle or malposition of the disc, an auditory problems may occur. Case report : The patient was referred to our clinic due to the suspicion of temporomandibular disorder from the local otorhinolaryngology clinic. A few days ago, his right ear could not be heard. MRI showed that the left TMJ disc was anterior displacement with reduction, the right TMJ disc was anteromedial displacement without reduction. Also Right mandibular condyle showed sclerotic bone change, subchondral cyst and was compressing the frontal wall of the ear on MRI view. Right TMJ arthroplasty was done under the diagnosis of right TMJ osteoarthritis and osteochondroma. Postoperative intermaxillary fixation was done with SAS screw and elastics for 2 weeks. One month after the operation, hearing and TMJ discomfort were recovered without any complications. Conclusions As seen in this case, hearing loss due to benign tumor-like lesions of the temporomandibular joint should be treated surgically to restore the TMJ function and hearing.

  • In the management of temporomandibular joint(TMJ) disorders, dental practioner should conduct the reversible, conservative, and inexpensive treatment modalities prior to the irreversible and invasive treatment. That is to say, behavioral, pharmacologic, and physical therapy should be conducted firstly, and then the occlusal appliance therapy could be considered. If patients do not react to these conservative treatments, we have to consider surgical treatments. If the accurate diagnosis is confirmed by intimate history taking, clinical and imaging examinations, we can rehabilitate the normal TMJ function and relieve the clinical symptoms with only conservative treatments in most TMJ disorder cases.
