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.

Ordination and cognitive complexity as related to clinical depression.

Personal construct psychology has contributed substantially to our understanding of psychopathology. The few studies of personal construct psychology in depression have focused on the content of self-constructs and cognitive complexity. The purpose of this study was to examine the construct system in depressed patients by investigating the relation of depressive symptoms to the content of constructs about others, cognitive complexity, and ordination.

The surgical correction of vertical maxillary excess (long face syndrome).

The surgical correction of vertical maxillary excess is a relatively new technique. Vertical maxillary excess (VME) may exist alone or in combination with a horizontal mandibular deficiency with or without an anterior open bite. The facial contour is characterized by a long, tapering face with anterior and posterior maxillary overgrowth, a narrow alar base, and lip in competence.

Recurrent ameloblastoma in autogenous rib graft. Report of a case.

Recurrent tumors in previously placed bone grafts are rare. A case of recurrent ameloblastoma in a rib graft 13 years after resection and reconstruction is presented. A review of the literature discloses only one cases of ameloblastoma recurring within a bone graft.

Instrumentation for styloidectomy.

Instrumentation that prevents injury to the structures of the tonsillar fossa during styloidectomy was presented. We think that by using this instrumentation, in particular the antral curet, the potential hazards are greatly reduced, if not eliminated.

Chronic sclerosing osteomyelitis: treatment considerations in an atypical case.

Chronic sclerosing osteomyelitis has been frequently described in the literature but little has been recommended for the management of the resistant cases that fail to respond to conservative treatment. This report describes the long term management of a particularly aggressive case of CSO and indicates maxillary sinus disease as a possible etiologic factor in CSO of the maxillary alveolus. Treatment required in more extensive cases must be as aggressive as dictated by the entire disease process and the total medical evaluation.

Treatment of radiation-induced tissue injury by hyperbaric oxygen.

Hyperbaric oxygen therapy appears to be a beneficial adjunctive treatment modality in the management of radionecrosis of bone and soft tissue in the head and neck. The mechanism of such wound healing enhancement appears to be related to oxygen stimulation of fibroblastic activity and neovasculation. In this pilot study, involving 13 cases of refractory mandibular radionecrosis treated with hyperbaric oxygen, complete healing of soft tissue disease with covering of exposed bone has been noted in seven cases 11 to 27 months posttreatment; transient healing was seen in three cases; moderate to marked improvement in soft tissue disease has been noted in three cases.

A prototype articulator for planning orthognathic and craniofacial surgery.

Current techniques and hinge-type articulators do not provide sufficient information and versatility for the planning of orthognathic and craniofacial surgery. Dental articulators either require plaster of paris for mounting or they do not accommodate movement of both casts in all directions of space. A prototype articulator that satisfies movement of both casts in all directions of space is successfully being used as an adjunct in planning orthognathic and craniofacial surgery.
