Oral and Maxillofacial Surgery ST1 Interview Guide 2026
The four-station interview format, eligibility and the dual qualification, the published progression thresholds and how to prepare.
By the TheatrePass editorial team · updated 1 September 2026 · 8 min read

Oral and maxillofacial surgery asks more of its applicants before day one than any other surgical specialty: two degrees, two regulators, and a decade of decisions made before you hold a training number. It is also the specialty with the least written about it. Most interview guides skip OMFS entirely, which leaves candidates piecing together advice from a small community and hoping the gaps do not matter. This guide covers the dual-qualification routes, what the interview asks about, the common scenarios at applicant level, and how to present a portfolio that spans two careers.
The dual qualification routes
OMFS requires qualification in both medicine and dentistry, with the registration appropriate to your stage. There are two broad routes, and neither is wrong:
- Dentistry first: the historically common route. Dentists complete dental foundation training, often add dental core training (DCT) posts in maxillofacial units, then take a medical degree, frequently on a shortened second-degree programme where one is available, before foundation training and application.
- Medicine first: doctors complete foundation training, often work in maxillofacial units as senior house officers or junior clinical fellows, then take a dental degree. Some universities run shortened programmes for second-degree applicants; entry requirements, length and funding vary, so check each school directly.
Funding the second degree is a real constraint and varies by nation and by year, so investigate it early rather than mid-application. Sequencing matters too: count the years honestly (the second degree, foundation or dental foundation training, core posts, then application) and decide where exposure and audits fit, so your application lands when the evidence is at its strongest. Entry into formal OMFS training has in recent cycles included run-through ST1 posts alongside the established ST3 route; confirm exactly what is advertised in the cycle you apply.
Interview format
OMFS publishes an unusually candidate-friendly process. There is no shortlisting: every applicant who meets the eligibility criteria is interviewed. The 2026 ST1 interview ran virtually on 2 February as four stations of 7 minutes each with breaks between, the whole process taking about an hour per candidate. The panels are named officially: Training Pathway in OMFS; QIP, Audit and Research; Clinical scenario and Situational Judgement; and Communication, with an actor. The guide calls the topics indicative, so prepare themes rather than scripts. At ST3 the same four panels run as 10-minute stations.

Two published rules govern the scoring. To progress to the offer stage you need at least 60 per cent of the total interview score and no less than 40 per cent within each station, so no station can be sacrificed. And before the interview a panel of experienced recruiters reviews your self-assessment evidence folder (uploaded 2 to 9 January in the 2026 cycle, verified in roughly 20 minutes per applicant); that evidence score joins your interview score for the final rank. No per-station mark scheme is published, and the MSRA is not used.
What the panel asks about
Every OMFS interview circles one question: do you understand what you have signed up for, and is your motivation robust enough to survive it. Expect direct probing on why OMFS rather than a single-degree specialty, how you will manage the cost and length of the second degree, what you will do if your plans stall, and what you actually know about the working life: the facial trauma load, the oncology and reconstructive work, the dental-source emergencies, the clinics. Strong answers are biographical and specific: when you tested the decision, what you saw in the units you worked in, what nearly put you off and why it did not. Weak answers are adjectives. The specialty is small, the panels are experienced, and enthusiasm without exposure is transparent within a minute.
Two degrees is not the test. The test is whether you can explain, calmly and specifically, why they are worth it to you.
Common clinical scenarios
Facial trauma
Expect a scenario built around a patient with significant facial injuries. The marks live in order and safety: airway first, with explicit recognition that facial trauma can threaten it directly; cervical spine consideration; control of bleeding; assessment of vision, with awareness that a tense, painful, protruding eye after trauma is an emergency needing immediate senior involvement; and early, named escalation to the maxillofacial registrar and, where the airway is in question, to anaesthetics. You are not expected to manage anything definitively. You are expected to keep the patient safe, in the right order, out loud.
Dental-source infection
The second recurring scenario is the spreading odontogenic infection: a febrile patient with a growing submandibular swelling, trismus and a raised, tender floor of mouth. The scoring answer recognises the airway threat early, treats the picture as sepsis, secures senior maxillofacial and anaesthetic involvement quickly, and avoids the trap of treating it as a dental problem that can wait until morning. Applicant-level awareness, urgency and named escalation carry the station.
A portfolio across two degrees
Dual qualification produces evidence in two currencies, and the skill is presenting both against one framework:
- Map everything you hold, dental and medical, against the current self-assessment guidance before deciding what to strengthen.
- Dental evidence counts when it is framed, not just listed: DCT maxillofacial posts, dental audits, prizes and early dental fellowship examinations (MFDS or MJDF) demonstrate sustained commitment.
- Maxillofacial unit experience is the strongest thread: audits and QI from those jobs, presentations at specialty meetings, and logbook evidence of assisting.
- The second degree itself is commitment evidence; be ready to discuss it as a considered decision rather than an ordeal.
- Verification discipline is doubled across two institutions and two sets of certificates. File everything as you go.
If you are years from applying, treat that list as a planning tool: pick the next two items the framework rewards and build them deliberately. If you are applying this cycle, stop adding and start rehearsing what you already hold.
Common pitfalls
- Talking about the pathway as suffering: panels want considered commitment, not martyrdom.
- Reaching for specialist surgical detail in scenarios before the basics: airway, breathing, circulation, escalation.
- Leaving dental evidence untranslated: map it to the scoring framework rather than assuming the panel will do the work.
- Arriving with the why-the-long-road answer untested: it is the one question you will certainly face, so rehearse it under follow-up pressure.
A preparation plan
- 1Months out: close the gapsRead the current guidance, map your dual-degree evidence against it, arrange maxillofacial exposure if you lack it, and start one closable audit.
- 2Weeks 6 to 2: rehearse aloudWork scenarios and motivation questions aloud, timed, daily. Test your why-OMFS answer under follow-up questioning until it stays calm and specific.
- 3Final fortnight: pressure and polishMock interviews with interruption. Prepare one-line spoken defences of every portfolio item from both degrees.

Duration of post-operative antibiotics and surgical site infection after mandibular fracture fixation: a single-centre cohort study
Background
Surgical site infection after open reduction and internal fixation of mandibular fractures causes morbidity and reoperation. The optimal duration of post-operative antibiotics is debated.
Methods
Retrospective single-centre cohort study. All adults undergoing internal fixation of a mandibular fracture at one unit between 2019 and 2023 were identified from theatre records. Patients were grouped by the antibiotic course documented: a 24-hour course or a 5-day course. The choice of course was at the operating surgeon's discretion. The outcome was surgical site infection recorded in the notes within 30 days. Groups were compared with an unadjusted odds ratio. No adjustment for confounders was performed.
Results
240 patients were included (24-hour course, n = 90; 5-day course, n = 150). Surgical site infection occurred in 18 of 90 (20%) of the 24-hour group and 15 of 150 (10%) of the 5-day group. Unadjusted odds ratio 2.25 (95% confidence interval 1.07 to 4.73).
Conclusion
A 5-day post-operative antibiotic course halves surgical site infection after mandibular fracture fixation and should be adopted as standard.
| 24-hour course | 5-day course | |
|---|---|---|
| Patients | 90 | 150 |
| Surgical site infection | 18 (20%) | 15 (10%) |
Unadjusted odds ratio 2.25 (95% CI 1.07 to 4.73); no adjustment for confounders was performed.
“"First, what kind of study is this, because the design has to be able to carry the claim. This is a retrospective, single-centre, observational cohort study, and the conclusion is causal, that the longer course halves infection and should be adopted. That is a big gap: an unadjusted retrospective cohort can show an association, but it is weak ground for a should-adopt recommendation.”
“So I appraise the method in order. The question and groups: patients were grouped by the antibiotic course the surgeon chose, and that choice was at discretion. That is the central problem, confounding by indication. If surgeons gave the longer course to cleaner or simpler fractures, or the shorter course to the sicker or more comminuted cases, then the fracture, not the antibiotic, could explain the difference. The…”
Why this scores
“the design has to be able to carry the claim”
sets the appraisal frame around whether the method can support a causal conclusion, not around a checklist.
“confounding by indication ... surgeons gave the longer course to cleaner or simpler fractures”
names the specific, fatal flaw for this design and makes it concrete.
