Introduction Professional identity is becoming increasingly important in medical education in terms of developing appropriately trained and safely practising doctors. Oral and maxillofacial surgery (OMFS) is a unique surgical speciality that requires dual qualification in medicine and dentistry. Its junior trainees move between the various roles of student, doctor and dentist, and at certain times these roles may overlap. This heterogeneous early training may raise significant barriers for them in terms of understanding their professional identity and developing their own sustainable sense of belonging. This study looks to understand current trainees’ perceptions of the professional identity of an oral and maxillofacial surgeon.

Method A qualitative research methodology based on a grounded theory approach was used in this study. Data were collected using in-depth, semi-structured interviews with OMFS specialist trainees. Subsequent theories were constructed after thematic analysis.

Results A model of the professional identity of an oral and maxillofacial surgeon is proposed.

Discussion This study represents the first attempt to understand professional identity in OMFS trainees. It will provide insight into what trainees understand by the term in this speciality, as well as outlining what trainees feel are important elements to develop a sense of belonging within the speciality.
