Chronic recurrent TMJ dislocation results in difficulty of mastication, speaking, and swallowing due to the limitation of the mandibular movement. Etiologic factors are considered as the looseness of the capsule and ligaments, the decrease of the articular eminence, condylar morphologic change, muscular disharmony near by TMJ, and the decrease of the vertical length of the mandibular ramus. Treatment approach has been suggested that surgical methods are selected for the correction of the etiologic factors when conservative treatments are not effective. Many surgical methods have been reported such as eminectomy, eminence augmentation, condylotomy, and zygomatic arch down fracture technique. We performed the eminence augmentation through interpositional bone graft in chronic recurrent TMJ dislocation. This method leads to favorable postoperative result without recurrence and complication, so we report the case with related references.

Dislocation of temporomandibular joint (TMJ) is troublesome condition which was most commonly shown far anteriorly displaced mandibular condyle to the articular eminence, thereby make it impossible to close one's mouth. It is often referred to as 'open lock' in clinically. Although anatomical modification of the articular eminence through eminectomy has been considered most satisfactory and efffective treatment for managing the recurrent dislocation, it seldom performs clinically due to its invasiveness and patient's reluctance. We thought a shortterm intermaxillary fixation could be of benefit to the patient suffering from recurrent dislocation. A 21-year-old male patient with recurrent TMJ dislocation which had developed after excessive mouth opening, was successfully treated with intermaxillay fixation using microimplant for 2 months. It is more conservative and less complicated method than eminectomy in treating recurrent TMJ dislocation. Transient intermaxillary fixation using microimplant and elastics could be one of treatment options for recurrent TMJ dislocation.

Recurrent mandibular dislocation is frequent morbidity of temporomandibular joint relatively. There are many etiologic causes in TMJ disorders but, difficult to find obvious one. Various treatment methods have been utilized for a mandibular dislocation. It is categorized into two groups broadly - nonsurgical or surgical methods. The basic rationale of the surgical method is to allow free movement of the condyle by reducing height of articular eminence or to limit anterior excessive movement of the condyle by increasing height of articular eminence or soft tissue anchoring procedure. In this case, 69 year-old woman was treated by augmentation of the articular eminence with mandibular symphysial bone graft leading to osteosynthesis without difficulty. As a result, favorable postoperative outcome was obtained functionally without any complication or recurrence.

Mandibular condylar hyperplasia is an uncommon condition of excessive unilateral growth of the condyle causing facial asymmetry and occlusal alterations. The etiology of condylar hyperplasia is unclear, but several factors are suspected, including previous trauma, hormonal disturbances, and abnormal functional loadings. Acute or chronic recurrent dislocation of temporomandibular joint (TMJ) is common, but long-standing dislocation is rare. We present two cases of the exophytic condylar hyperplasia that lasted for over 20 years with TMJ dislocation. In both cases, we performed a condyloplasty to restore normal occlusion and facial symmetry, with satisfactory results.

턱관절의 탈구는 과두가 관절와를 벗어나 환자 스스로 원래 위치로 정복하지 못할 때 발생한다. 양측성 전방 탈구가 가장 흔하며 탈구의 빈도와 발생 기간에 따라 급성, 만성, 재발성으로 분류하기도 한다. 턱관절 탈구의 치료법으로 수조작 같은 보존적 방법부터 수술적 접근법까지 다양한 방법들이 있으며 치료법의 선택은 주로 탈구가 발생한 기간에 따라 달라진다. 본 증례를 통해서 수조작을 시행하여 턱관절의 탈구를 성공적으로 치료한 증례와 과두의 정복에 실패했으나 만성적으로 적응된 환자에서 수술적 치료 대신 보철 치료로 교합을 회복시켜준 사례를 소개하고 그 의의에 대해 고찰해보고자 한다.
