ENT questions show up consistently on MRCS Part A. Most candidates see around 15 to 20 questions from this subject, which makes it one of the higher-yield areas you can prepare for. The good news is that ENT in MRCS Part A stays fairly predictable. A focused list of topics, revised properly, will cover most of what comes up. Dr Vinayak Rengan who is the founder of Mortimer Green strongly believes that the percentage of ENT questions in MRCS Part A are increasing every year.

Here's a breakdown of the topics worth prioritising, along with some notes on where candidates typically lose marks.

1. Thyroid Malignancies

Thyroid cancer questions are almost guaranteed on every MRCS Part A paper. Know the four main types:

  • Papillary carcinoma
  • Follicular carcinoma
  • Medullary carcinoma
  • Anaplastic carcinoma

For each one, be clear on the pathological features, typical age group, spread pattern (lymphatic vs haematogenous), and prognosis. Examiners also like to test surgical indications for thyroidectomy and the complications that follow it, so don't stop at diagnosis alone.

2. Tracheostomy

This topic comes up in both its emergency and elective forms, and candidates often mix up the indications for each. Go through:

  • The difference between emergency and elective tracheostomy
  • Indications for each
  • The steps of the procedure itself

Questions here tend to test practical understanding rather than pure recall, so working through the procedure step by step helps more than memorising a list.

3. Lateral Neck Swellings

Neck lump questions are a classic MRCS Part A staple, and the examiners love testing the differences between similar-looking conditions. Cover:

  • Branchial cleft cysts
  • Thyroglossal duct cysts
  • Cystic hygroma
  • Dermoid cysts

Pay close attention to location, age of presentation, and any movement with swallowing or tongue protrusion, since these details are usually what separates the right answer from the wrong one.

4. Premalignant Lesions of the Oral Cavity

Oral premalignant conditions are an easy source of marks if you know the basics. Focus on:

  • Leukoplakia
  • Erythroplakia
  • Oral submucous fibrosis

Know the malignant transformation risk for each and the typical risk factors associated with them, particularly tobacco and areca nut use.

5. Epistaxis and Nasal Polyps

This section covers two distinct but frequently tested areas:

  • Kiesselbach's plexus and the common causes of epistaxis
  • Samter's triad in nasal polyposis
  • Standard management protocols for both

Epistaxis questions often test first-line management steps, so make sure you know the order of interventions rather than just the anatomy.

6. Sensory Innervation of the Face

Trigeminal nerve anatomy is a recurring theme across MRCS Part A, not just in the ENT section. Revise:

  • The three branches: V1, V2, V3
  • Their sensory distribution
  • Applied anatomy relevant to facial trauma and surgery

This topic rewards a solid grasp of anatomy diagrams rather than rote memorisation.

7. Complications of Head and Neck Surgeries

Post-operative complications are a favourite examiner topic because they combine anatomy with clinical reasoning. Know:

  • Recurrent laryngeal and superior laryngeal nerve injury
  • Hypocalcaemia following thyroidectomy
  • Frey's syndrome after parotidectomy

Understanding why each complication happens, tied to the anatomy involved, makes these much easier to answer under exam conditions.

How to Structure Your ENT Revision

Once you've gone through the topics above, the next step is practice. Reading through notes only gets you so far. Working through single best answer (SBA) questions on each topic helps you spot the specific way MRCS examiners like to frame ENT questions, and shows you where the gaps in your understanding actually are.

This is where a good question bank makes a real difference. The Mortimer Green app is built around exactly this kind of focused, exam-pattern practice for MRCS Part A.
