| Research Abstract |
In clinical investigation, MRI in combination with 3 dimensional imaging and Turbo-FLASH method was attempted to clarify the detail pathology in internal derangement of the temporomandibular joint. In comparison MRI disk shape, type of disk displacement) with clinical signs and symptoms, showed 1) minor deformity of the disk in click cases, 2) disk reduction point was correlation with clinical signs, 3) tend of more anterior of disk reduction point in intermittent lock cases. Simple diagnostic arthroscopy developed to detect intraarticular pathology realized the high frequency of adhesion in internal derangement, which should be taken off. In therapeutic modality of jont noize, the procedures and outcomes in both conservative and surgical treatments, as well as, definitions in surgery for joint noize were demonstrated. In fundamental investigations, postoperative healing process in several arthroscopic surgeries were identified in experimental animal studies. Especially, cartilage regeneration was poor following arthroscopic eminoplasty, arthroscopic suturing and diskectomy. Moreover, some irreversible affects were shown in these operations, which can help the appropriate indication of surgical intervention for jont noize of temporomandibular joint disorders.
