Service-mix of oral and maxillofacial surgeons in Australia and New Zealand.

This study aimed to investigate the service-mix of oral and maxillofacial surgeons and its association with patient age, sex, and referral sources. Oral and maxillofacial surgeons in Australia and New Zealand were surveyed (n = 97; 71.9% response rate), and they supplied service-mix data from a week-long log of services provided to 5770 patients. Dentoalveolar services comprised 67.0% of services. Subcategories of service-mix showed high levels of removal of unerupted teeth (44.8%) and multiple extractions (10.0%), with soft-tissue lesions (5.0%), TMJ surgery (4.7%), mandible trauma (4.6%), and simple extraction (4.4%) the next categories in order of percentage. Variations in service-mix were observed for patient age and sex, among referral sources, and between private and public practice.

A consensus approach to projections of the supply of oral and maxillofacial surgeons in Australia.

The analysis presented involves projections of the future requirements for the oral and maxillofacial surgeon labour force in Australia under a range of different recruitment scenarios, followed by a consensus-seeking exercise with the Australian and New Zealand Association of Oral and Maxillofacial Surgeons (ANZAOMS) Council in an attempt to produce estimates of the most probable future requirement for oral and maxillofacial surgeons. The resulting consensus estimates would result in the maintenance of the present population-to-surgeon ratio. Different premises or beliefs underlying the projections were viewed as counterbalancing each other.

The opinions of 100 international experts on temporomandibular joint surgery. A postal questionnaire.

A postal survey of the views of 100 international experts in temporomandibular joint surgery was performed. Generally, there was a considerable degree of consensus on definitions, diagnosis, and broad treatment principles. However, specific surgical techniques for particular stages of internal derangement and osteoarthrosis as well as measurement of treatment outcome clearly need more consideration and investigation.

Toward an international consensus on temporomandibular joint surgery. Report of the Second International Consensus Meeting, April 1992, Buenos Aires, Argentina.

This consensus statement reflects the current status of temporomandibular joint surgery in the international community of oral and maxillofacial surgeons in the early 1990s. It is not the end, and it is not the beginning; it is a step forward in the treatment of patients with temporomandibular disorders. It is hoped that this statement will encourage member organizations, and individual members to pursue the issues raised by the proposed criteria. Also there should be continuing debate on the findings presented and on future developments, as well as efforts to teach others the skills the specialty has acquired.

A multivariate study of patients with temporomandibular joint disorder, atypical facial pain, and dental pain.

The multifactorial nature of oral and facial pain was investigated by the collection of clinical and psychologic data from 312 patients with either dental pain, temporomandibular joint disorder, or atypical facial pain. Significant differences between the groups in gender and age distribution, muscle and joint pain, radiographic joint changes, number of remaining teeth, pain duration, and aspects of the patients' perception of pain were evident. In addition, discriminant function analysis clearly differentiated between the three groups on the basis of both clinical and psychologic variables, emphasizing the multifactorial nature of oral and facial pain.

A model for osteoarthritis of the temporomandibular joint.

There is a need for a simple, reproducible animal model of advanced osteoarthritis of the temporomandibular joint (TMJ). In this study, gentle removal of the condylar articular layer in the sheep TMJ resulted in an eburnated condyle with peripheral osteophytes, thin or perforated discs, and temporal surface proliferation. This model can be used for both the study of osteoarthritis and the evaluation of therapeutic methods.

Effect of marrow perforation on the sheep temporomandibular joint.

The effect of surgically perforating the mandibular condyle to allow synovial fluid to contact the marrow was examined in 5 sheep temporomandibular joints. The surgical defect showed replacement of the marrow with fibro-osseous tissue and subcortical cysts. A vertical, central osteophyte emerged from the perforation, causing attenuation or perforation of the disc and temporal surface proliferation. These changes were radiographically and histologically similar to advanced osteoarthritis. This supports the concept that intraarticular micro or macrofracture may result in osteoarthritis.

Effect of fascia repair of the temporomandibular joint disk of sheep.

The effects of temporal fascia graft repair of temporomandibular joint disk perforation on intra-articular structure were examined on four sheep. Four sheep had bilateral disk perforations. At 20 weeks the perforation in the right joint was repaired with a temporal fascia graft. At 40 weeks the sheep were killed and the joints were examined radiologically and histologically. It was found that the temporal fascia graft did not survive and the disks remained perforated. However, histologically and radiologically there were fewer changes than in the joints where the perforated disks were not repaired.

The effect of Silastic replacement following discectomy in sheep temporomandibular joints.

The effect of Silastic (Dow Corning, Midland, MI) replacement following discectomy was examined in sheep temporomandibular joints (TMJs). Four sheep had disc perforations created bilaterally, and 20 weeks later the right disc was removed and replaced with a Silastic sheet. At 40 weeks following commencement of the study, the sheep were killed and the TMJs examined radiologically and histologically. The TMJs of two unoperated sheep were similarly evaluated to determine normal findings. Radiologic examination showed destructive bony change in all four operated joints. Histologic examination confirmed these bony changes in both the temporal bone and condyle. There were foreign particles with an accompanying foreign-body reaction throughout the fibrous tissue capsule that had formed around the implant.

Effect of experimental disc perforation in sheep temporomandibular joints.

The effect of surgical perforation of the disc on intra-articular morphology was examined using sheep. Eight sheep had bilateral perforations and 2 animals were used as controls. After 8 months the sheep were killed and the joints examined radiologically and histologically. Osteophytes were seen on all the condylar radiographs. Histologically, there were proliferative changes in both the condylar and temporal surfaces adjacent to the disc perforations.

The scope of oral and maxillofacial surgery in Australia and New Zealand. A postal survey.

The current scope of oral and maxillofacial surgery in Australia and New Zealand was explored with a survey of full members of the Australian and New Zealand Association of Oral and Maxillofacial Surgeons resident in the region. There was an 83 per cent usable response rate and the objectivity of the data was confirmed by check questions and material from other sources. The study showed that oral and maxillofacial surgery is the surgical specialty of dentistry with the core of referral and surgical services being dento-alveolar. However, the essential knowledge of the anatomy, pathology, and surgery of the orofacial region forms the basis for the wider scope of modern oral and maxillofacial surgery. Current surgery includes management of trauma, pathology, dentofacial deformity, and a wide range of reconstructive surgery including grafts and implants.

The radiologic morphology of asymptomatic temporomandibular joints.

A high frequency of remodeling changes was demonstrated radiographically in a series of 200 female patients with asymptomatic temporomandibular joints. Fewer than 10% of joints were completely radiologically "normal". Generally, there was an increasing incidence of changes with increasing age and for edentulous patients, but these relationships were by no means direct or mutually exclusive.

The radiologic morphology of painful temporomandibular joints.

A high frequency of remodeling changes was demonstrated radiographically in a series of patients having pain in the temporomandibular joint region. Radiologic morphologic differences between painful and asymptomatic temporomandibular joints were in frequency rather than type. Caution should be taken not to overestimate the significance of radiologic abnormality in patients with pain in the temporomandibular joint region.

The arthroscopic appearance of acute temporomandibular joint trauma.

The arthroscopic appearance of the temporomandibular joint following acute trauma sufficient to result in mandibular fracture was described in 40 joints in 20 patients. It was found that 38 of 40 joints showed evidence of intra-articular damage. Hemarthrosis with shredding of the disc and joint surfaces was the most common finding. The hemarthrosis rapidly resolved but the shredding remained. The degree of damage was related to the site of mandibular fracture with the most damage being seen when the condylar neck was not fractured.

Effect of training on the scope of oral and maxillofacial surgery.

The relationships between training and qualifications and the scope of oral and maxillofacial surgical practice was investigated by a survey of all full members of the Australian and New Zealand Association of Oral and Maxillofacial surgeons. It was found that scope did correlate to length of training. Three were differences in scope for more recently trained surgeons and by practice location. The possession of medical qualification did not necessarily affect scope of practice but did affect attitudes.

Psychological factors in temporomandibular joint dysfunction: life events.

Psychological and emotional factors are clearly involved in the development of temporomandibular joint dysfunction (TMJD). They also are involved in whether the patient chooses to present for treatment and how they react to the health care professional and treatment. However, many previous studies have been simplistic in that they look at a particular psychologic aspect in isolation. In this series of studies, a multivariate analysis of a broad range of psychologic and physical variables in a TMJD group (N = 105) and a matched control group (N = 90) was performed. The methodology of the study is described in detail in this paper. Patients with high life events were compared with those with low life events. A simple relationship of high life events to development of TMJD was not demonstrated. However, high life events did correlate directly with other psychological parameters and to the development of illness behaviour.

Psychological factors in temporomandibular joint dysfunction: anxiety.

This study was to clarify the relationship between anxiety and temporomandibular joint dysfunction (TMJD) in a group of patients with TMJD (N = 105) and a matched control group (N = 90) using measures of anxiety, relevant physical parameters and a number of other psychological variables. Patients were divided into high and low anxiety groups using the Spielberger Anxiety Inventory and compared using measures obtained from the Gerke-Goss Inventory on Dental and Psychological Factors. Statistical comparison revealed no significant differences between the anxiety groups in physical parameters. Both of the TMJD groups (high and low anxiety) revealed more prominent features of Abnormal Illness Behaviour as compared to the control groups (high and low anxiety). This prominence of Abnormal Illness Behaviour was most evident in the TMJD group with low anxiety, a finding which may have further clinical implications.

Psychological factors in temporomandibular joint dysfunction: depression.

This study was to clarify the relationship between anxiety and temporomandibular joint dysfunction (TMJD) in a group of patients with TMJD (N = 105) and a matched control group (N = 90) using measures of depression, relevant physical parameters and a number of other psychological variables. Patients were divided into high and low depression groups using the Zung self-rating depression scale and compared using measures obtained from the Goss-Gerke Inventory on Dental and Psychological Factors. Statistical comparison revealed no significant differences between depression groups in physical parameters. The TMJD groups were generally more depressed than the control group. The highly depressed TMJD group had a greater degree of abnormal illness behaviour and generally were similar to those patients identified in other studies as being refractory to treatment.
