No effect of neuromuscular blockade on the temporomandibular joint position during general anesthesia.

In an attempt to determine the role that nondepolarizing neuromuscular blocking agents play in the intraoperative position of the mandibular condyle, occlusal checkbites were taken on 10 patients under general anesthesia before and after neuromuscular blockade with vecuronium. These checkbites were compared to checkbites taken preoperatively. Nondepolarizing neuromuscular blocking agents had no effect on condylar position recordings during general anesthesia.

Ankylosing spondylitis associated with temporomandibular joint ankylosis: report of a case.

Ankylosing spondylitis is a disease process that causes inflammatory changes of the involved joints. Often the first clinical indication of the condition is lumbosacral pain and discomfort with limited range of motion. Progressive synovial changes eventually involve all of the axial joints including the temporomandibular joint.

Synovial chondromatosis of the temporomandibular joint diagnosed by magnetic resonance imaging: report of a case.

A case of synovial chondromatosis of the temporomandibular joint with extracapsular extension is described. Temporomandibular joint magnetic resonance imaging proved invaluable in establishing a definitive diagnosis.

Continuous infusion of methohexital and alfentanil hydrochloride for general anesthesia in outpatient third molar surgery.

Three anesthetic techniques were compared in this study: 1) Intermittent Brevital boluses supplemented with fentanyl and midazolam all titrated to patient movement, 2) constant infusion of Brevital supplemented with fentanyl and midazolam all delivered in calculated mg/kg doses based on total body weight, and 3) constant infusion of methohexital (Brevital) and alfentanil (Alfenta) supplemented by midazolam (Versed), droperidol, and glycopyrolate (Robinul) delivered in calculated mg/kg doses based on lean body mass. Nitrous oxide was delivered in all cases via nasal mask in a 30% to 50% concentration. The mean total dose of Brevital in group 1 (intermittent Brevital bolus) was 0.
