Recognition of profile change after simulated orthognathic surgery.

Fifty-one oral and maxillofacial surgeons, 52 orthodontists, 51 orthognathic surgery patients, and 100 lay persons evaluated life-size lateral photographs of two male and two female subjects that had been altered to simulate varying amounts of surgical correction of mandibular retrognathism and prognathism. A horizontal change at pogonion of less than 4 mm was generally not recognized by more than half of the lay groups. The dental groups were more accurate, but even they did not achieve better than 80% recognition until 6 mm of change. Both the dental and lay groups recognized change more easily in the female and the prognathic subjects. When asked which feature appeared changed, dentists generally indicated the chin and lay groups the lips.

Smoking habits and attitudes of oral and maxillofacial surgeons.

A survey was done on the smoking behavior and attitudes of 1349 fellows and members of the American Association of Oral and Maxillofacial Surgeons. It was found that only 8% of this group currently smoke, 40% were former smokers, and 52% had never smoked; the nonsmokers were significantly younger than the smokers. The respondents generally did not permit smoking in the waiting room, and were active in advising patients against smoking and in follow-up on their use of tobacco. It was concluded that although there is still room for improvement, oral and maxillofacial surgeons are currently quite effective in controlling their own smoking habits and in helping their patients to do likewise.

Diagnosis and treatment of myofacial pain-dysfunction (MPD) syndrome.

The successful management of patients with MPD syndrome is dependent on establishing an accurate diagnosis and using proper therapy based on an understanding of the etiology of the disorder. Establishing an accurate diagnosis is accomplished by taking a careful history, doing a thorough examination, and having a knowledge of the various other conditions that can produce signs and symptoms similar to those of MPD syndrome. Using proper therapy is related to recognition that MPD syndrome is a stress-induced psychophysiologic disease originating in the muscles of mastication and not an organic disease arising in the temporomandibular joint. Thus, therapy should be directed at reducing stress, relaxing tense jaw muscles, and creating an awareness by the patient of the causes of the problem, rather than at analyzing occlusion, measuring joint spaces, and producing irreversible structural changes in the dentition and the articulation. Because good results can be achieved with these uncomplicated, reversible forms of therapy, it is important that the clinician does not succumb to an unproven fad or use of an irreversible procedure that will not achieve better results.

Incidence of temporomandibular symptoms in patients with major skeletal malocclusions: a survey of oral and maxillofacial surgery training programs.

A survey was done of 116 graduate training programs in oral and maxillofacial surgery to determine (1) the percentage of patients screened for orthognathic surgery who had symptoms of temporomandibular pain and dysfunction preoperatively and (2) how many who were asymptomatic preoperatively developed temporomandibular symptoms postoperatively. Of the fifty-one programs that responded, most reported that fewer than 20% of the patients were symptomatic before surgery and that few patients had symptoms postoperatively. The implications of these findings are discussed.

Comparison of panoramic and standard radiographs for the diagnosis of mandibular fractures.

This study was undertaken to compare the panoramic radiograph with the standard hospital mandibular series for the diagnosis of mandibular fractures. Of the 88 fractures present in the patient population, 92% were recognized in the panoramic radiograph, while only 66% were detected in the hospital series. All fractures seen in the hospital series were also seen in the panoramic view. It was therefore concluded that the panoramic view is superior to the standard hospital series for the diagnosis of mandibular fractures.

Prosthodontists' preferences in preprosthetic surgery.

A survey of members of the Federation of Prosthodontic Organizations was done to determine their opinions about various preprosthetic surgical procedures used to treat patients with alveolar atrophy of the maxilla and mandible. In most instances there was lack of consensus, indicating a need for consultation and close cooperation between the oral and maxillofacial surgeon and the prosthodontist in the management of individual patients.

Healing of surgical incisions in the disc and retrodiscal tissue of the rabbit temporomandibular joint.

The purpose of this study was to evaluate histologically the healing potential of surgical incisions placed in various areas of the TMJ disc and retrodiscal tissue. Eight weeks after surgery, it was found that incisions completely within retrodiscal tissue had healed and had a normal appearance. Incisions at the junction of the disc and retrodiscal tissue also had healed, but at a slower rate and with more random orientation of the collagen fibers. Defects within the disc had not healed, however, and degenerative changes had developed in the hard and soft tissues. The implications of these observations are discussed.

Pneumatization of the articular eminence of the temporal bone: prevalence, development, and surgical treatment.

Routine panoramic radiographs of 784 patients were evaluated retrospectively for the presence of pneumatization of the articular eminence of the temporal bone (PAT). The radiographs of eight patients showed signs of PAT. These eight patients ranged in age from 32 to 69 years, and four patients had bilateral involvement of the temporal bone. The use of tomography is recommended before surgical procedures involving the eminence to determine the extent of the pneumatization.
