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.
