Correlation between arthroscopic diagnosis of osteoarthritis and synovitis of the human temporomandibular joint and keratan sulfate levels in the synovial fluid.
The specific aims of this investigation were to determine if there is a relationship between an arthroscopic diagnosis of synovitis and osteoarthritis, and if the presence of synovitis influences the level of cartilage degradation, as evidenced by keratan sulfate levels in the synovial fluid. ⋯ Osteoarthritis and synovitis are common diagnoses and are often present concurrently in patients with symptomatic temporomandibular joints. Osteoarthritis is associated with elevated keratan sulfate levels; however, the elevation of keratan sulfate is less in patients with concomitant synovitis.

Desflurane for outpatient general anesthesia in third molar extraction cases.
The purpose of this study was to evaluate the use of desflurane, a new volatile anesthetic agent, in a standardized endotracheal anesthetic technique for the removal of third molars in ambulatory patients. ⋯ The desflurane anesthetic technique provides a satisfactory surgical environment in selected patients. It results in rapid postanesthesia recovery and discharge times, thus reducing costs.

Long-term outcome of arthrocentesis for sudden-onset, persistent, severe closed lock of the temporomandibular joint.
This study analyzed the long-term effect of arthrocentesis for severe closed lock of the temporomandibular joint (TMJ) and reevaluated the pathogenesis of this condition based on the data obtained. ⋯ Arthrocentesis for sudden-onset closed lock provided sustained normal joint function and marked pain relief. Because the available literature shows that arthrocentesis changes neither disc position nor disc shape, it places in doubt the concept of a displaced and deformed disc limiting joint function. Rather, the efficacy of lavage in resolving closed lock suggests that the condition is the result of sudden adherence of the normally shaped disc to the fossa, rendering it incapable of sliding. The characteristic features of sudden-onset, limited mouth opening warrants classification of this disorder as an independent entity within the realm of TMJ disturbances.

Comparative Study Clinical Trial Controlled Clinical TrialA comparison of patient-controlled and fixed schedule analgesia after orthognathic surgery.
The purpose of this prospective study was to compare the effectiveness of patient-controlled intravenous (i.v.) opioid analgesic administration (PCA) with fixed schedule and dosage oral/rectal administration of naproxen, and opioid analgesics intramuscularly/orally as needed (i.m./p.o. prn) for postoperative analgesia over a period of 48 to 56 hours after surgery. ⋯ In patients undergoing orthognathic surgery, the naproxen and PCA regimens provided better analgesia than the codeine regimen.
