Maxillofacial trauma and the GDP - Specialty recognition and patterns of referral

Abstract

Objective: To investigate New Zealand GDPs' awareness of maxillofacial trauma and to identify their associated referral patterns. Design: Cross-sectional survey of a random sample of GDPs. Method: A nationwide postal questionnaire survey was sent to GDPs on the New Zealand Dental Register, maintained by the Dental Council of New Zealand. The questionnaire requested socio-demographic details, together with information on the availability of specialist services and their need for continuing professional development in oral and maxillofacial surgery (OMS). The questionnaire also asked the GDPs to indicate which specialty (plastic surgery, ear nose and throat (ENT) surgery, OMS and Other) they expected to manage—and to which specialty they would refer—seven types of maxillofacial injury. Results: Some 377 GDPs responded (76.6%). The majority of GDPs expected OMS to manage maxillofacial trauma, except for facial lacerations and isolated nasal fractures which were expected to be managed by plastic surgery (83.0%) and ENT surgery (79.7%), respectively. Most GDPs (48.0% to 87.9%) referred maxillofacial trauma to OMS, except for isolated nasal fractures, for which there were similar proportions referred to ENT surgery and OMS (45.8% and 41.4%, respectively). Differences in awareness of and referral patterns for maxillofacial trauma were identified by dentist characteristics. Most GDPs (96.0%) felt there was a need for continuing professional development in OMS, and most (84.1%) preferred this to be in the form of lectures and seminars. Conclusion: The first-ever study of GDP referral patterns for maxillofacial trauma in New Zealand has revealed that most GDPs in New Zealand referred maxillofacial trauma appropriately to OMS.
