Arthrotic changes and deviation in form of the temporomandibular joint--an autopsy study.

An autopsy study was performed on 84 left human temporomandibular joints. Frequency and location of osteoarthrosis and deviation in form were registered in each joint component. Locations of disc perforations were registered with special emphasis on involvement of the bilaminar zone. The anatomical relationship between the deep masseter muscle and the TMJ capsule was investigated in part of the material. Deviation in form was most frequent in condyles (53%) compared with temporal components (40%) and discs (15%). The relative frequencies of the three joint components were opposite for osteoarthrosis; discs (32%), temporal components (26%) and condyles (21%). Higher frequency of arthrotic changes was found in edentulous specimens than in dentulous ones. Disc perforations were located within disc tissue except for one joint where it also included part of the bilaminar zone. No correlation between sex and arthrosis and/or deviation in form was found. Insertion of the posterior fibres of the deep masseter muscle into the anterior capsule was macroscopically observed in six of ten joints.

Temporomandibular joint disorders: a diagnostic challenge.

During the past decade much interest has been focused on disorders of the TMJ. The etiology appears to be multifactorial, with signs and symptoms difficult to evaluate and radiologic investigations insufficient. This review attempted to analyze current diagnostic tools. The recent introduction of various techniques promises optimism for this diagnostic and therapeutic challenge.

Arthroscopy of the temporomandibular joint. A clinical study.

Temporomandibular joint (TMJ) arthroscopy on 30 joints of 26 patients with different signs and symptoms of TMJ arthropathy was evaluated. Local anaesthesia was used and proved efficient. In 27 cases, the superior, and in 3 cases both, compartments were punctured. Successful examination was performed in 26 superior and 3 attempted inferior compartments. Functional impairment following arthroscopy was minor and rarely lasted more than one week. No postoperative bleeding, nerve damage, or infection was observed. Of the 2 systems tested, the rod-lens arthroscope showed superior optical quality.

Long-acting local anaesthetics in oral surgery. Clinical evaluation of bupivacaine and etidocaine for mandibular nerve block.

2 long-acting local anaesthetics, bupivacaine and etidocaine, have been compared to lidocaine with regard to effect during surgical removal of impacted mandibular third molars and effect upon the immediate postoperative pain. It can be concluded from this study that both bupivacaine and etidocaine as well as lidocaine were highly effective and without significant difference with regard to pain blocking during surgery. Both long-acting solutions were significantly superior to lidocaine in providing an extended duration of postoperative pain control. Comparing the 2 long-acting solutions, patients in the bupivacaine group had a significantly longer pain-free period than patients in the etidocaine group.

Arthroscopy of the rabbit temporomandibular joint.

Arthroscopy of the rabbit temporomandibular joint was evaluated experimentally on 22 rabbits. A small arthroscope with so-called "Selfoc"-system was employed. The reaction to arthroscopy was analyzed clinically. Macroscopic dissection and histology were then employed to detect possible pathological changes in the joints at periodic intervals. The established criteria for evaluation of postoperative reactions were erythema, suppuration, weight changes and chewing capacity. The results of this study indicate that the rabbit temporomandibular joint may be arthroscoped with subsequent minor reversible changes. It also seems feasible to assume that temporomandibular joint arthroscopy in humans runs a low risk for postoperative complications.

Arthroscopy of the temporomandibular joint. An autopsy study.

Arthroscopy of the temporomandibular joint (TMJ) is evaluated on an autopsy material. 2 different types of arthroscope--one with a rod-lens system and one with a so-called Selfoc system--were used and compared regarding diagnostic accuracy. On 54 cadavers, it was found that the upper joint compartment may be punctured with accuracy and without damage to vital tissues. Landmarks on the skin facilitating clinical arthroscopy were defined in relation to a guideline from tragus to lateral canthus. A further 49 TMJ specimens were investigated with arthroscopy. The findings are in good agreement with subsequent observations made during dissection. Regarding arthrotic changes, 100% diagnostic accuracy was achieved with both types of arthroscope. Regarding remodelling changes, the diagnostic accuracy was approximately 57%. No significant difference was noticed between the 2 arthroscopes. Photographic documentation with the rod-lens arthroscope was found to be of superior quality.

Arthroscopy of the temporomandibular joint. Examination of 2 patients with suspected disk derangement.

2 patients with a history of reciprocal temporomandibular joint (TMJ) clicking were visually examined with arthroscopy of their right side TMJs. Clinical and radiographic examination revealed no signs of arthrosis deformans. One patient with significantly reduced opening ability combined with occasional disappearance of TMJ clicks showed advanced arthrotic changes of cartilage which were not visible radiographically. The other patient with unimpaired function also had a severe arthrotic lesion in the clicking joint. In neither case did the disk appear to be displaced. It is concluded that arthroscopy yields additional information for TMJ diagnosis which cannot be achieved by clinical and radiographic examination alone.
