Expectations of patients from orthognathic surgery.

Fifty-two patients were interviewed before and six months after corrective orthognathic surgery. These patients expected either a functional (39%), esthetic (17%), or combined functional and aesthetic (44%) outcome. All were satisfied with the functional change and 92% were satisfied with the esthetic change. Because almost all patients reported that the outcome of surgery was as expected, it seems unnecessary for the surgeon to be concerned about not recognizing hidden motives on the part of the patient. Some dissatisfaction was expressed with certain unexpected happenings during the surgical experience. If surgeons provide more detailed explanations of what to expect from the process of surgery, they can decrease this type of psychological trauma and increase the satisfaction of their patients.

Evaluation of sintered titanium fiber composite as a subperiosteal implant.

Seventy-two sintered titanium fiber composite implants were placed subperiosteally and anchored intraosseously on the lateral aspect of 12 dog mandibles. The implants were covered with either Millipore filter, silicone, or left uncovered. Analysis after the animals were killed showed that bone growth into the subperiosteal portion of the implants was maximal at three to six weeks after implantation and remained at a depth of 380 mu through 24 weeks in a majority of the implants. Bone growth into the intraosseous portion also peaked at three to six weeks and remained at 190 to 380 mu through 24 weeks. Covering the implants slowed the rate of osseous ingrowth but did not affect the depth. The implants were well tolerated and the material holds promise for use in oral and maxillofacial surgery.

Arthroscopic examination of experimentally induced pathologic conditions of the rabbit temporomandibular joint.

Because of the difficulty in diagnosing and treating diseases of the temporomandibular joint, there seems to be a need for a simple, safe technique of examination. The purpose of this study was to examine the usefulness of the arthroscope in diagnosing pathologic conditions of the temporomandibular joint. Various pathologic conditions were produced in the mandibular joints of rabbits. These included steroid-induced arthropathy, chronic inflammatory changes in the synovium, acute inflammatory disease, and gross damage to the condyle and disk. The joints were then visualized with the arthroscope and photographed. Biopsy specimens of what appeared to be the involved areas of the condylar surface and joint capsule were taken for histologic study. The arthroscopic findings were correlated with the biopsy findings and histologic sections of the entire joint.

Personality characteristics of patients with myofascial pain-dysfunction (MPD) syndrome unresponsive to conventional therapy.

The composite MMPI profiles of 42 successfully-treated and 42 unsuccessfully-treated female patients with MPD syndrome were compared statistically. The profiles did not differ in configuration, but that of the unsuccessful patients was significantly higher than that of the successful group, indicating a greater degree of emotional distress. The pattern of deviation from normal for both groups was diagnostic of a psychophysiological disorder marked by repression and somatization.

The specificity of response to experimental stress in patients with myofascial pain dysfunction syndrome.

Comparison of autonomic and muscular response to experimentally induced stress in normal individuals and patients with myofascial pain dysfunction (MPD) syndrome revealed greater masseter and frontalis activity in the patient group, higher gastrocnemius activity in control subjects, and no significant difference in skin conductance and heart rate. This specificity of response to stress supports the psychophysiologic theory of MPD syndrome.

The effects of local hypothermia on odontogenesis.

Cryosurgery, with temperatures ranging from -40 C to -140 C, was performed on 32 developing mandibular third and fourth premolar buds of dogs. Evaluations were made on clinical, radiographic, and histologic bases at prescribed time intervals. There was complete inhibition of odontogenesis in 62.5% of third premolars and 25% of fourth premolars. There was 25% partial inhibition of third premolars and a 56.25% inhibition of fourth premolars. The adjacent developing tooth buds and bone were not affected.
