Quick answer
How should I present a suspected acute mastoiditis case on rounds?
Open with the untreated ear infection and the specific red flags—ear protrusion and postauricular swelling—since these distinguish this from uncomplicated otitis media. State plainly that vital signs and a confirmatory exam are not yet documented. Name mastoiditis as the leading diagnosis and state that it needs IV antibiotics and urgent ENT evaluation, not oral antibiotics alone.
Before you speak
Define the moment and the information you actually have
A same-day urgent-care presentation before formal vital signs and imaging have been added to the simulated chart.
A supervising physician deciding on urgency of ENT referral and admission.
History only, including the untreated antecedent otitis media and the specific postauricular findings described by the caregiver. No vital signs, exam confirmation, or imaging are yet supplied.
About 70 seconds
Fictional training case: The presentation is locked to the simulated patient JSON. It names important unknowns instead of inventing an examination, vital signs, allergies, or tests.
Complete spoken example
First, read it once without stopping
The paragraph breaks show the clinical shape. In a real presentation, pause briefly between ideas rather than announcing the headings.
Mitchell is a 4-year-old girl with untreated acute otitis media who now has protrusion of her right outer ear and redness and tenderness over the mastoid bone behind it.
Her ear pain and high fever have continued from an ear infection that was not treated, and her caregiver now reports the outer ear looking pushed forward with visible swelling and tenderness behind it, worried about serious complications and a prolonged recovery.
She has no significant chronic medical history documented, and the fact that her original ear infection went untreated is itself an important part of the story here.
Vital signs and a confirmatory physical examination, including formal assessment of the ear displacement and mastoid tenderness, have not yet been documented in this simulation, so I cannot confirm severity or complications from the history alone.
My leading diagnosis is acute mastoiditis complicating untreated otitis media, based on the ear protrusion and postauricular swelling and tenderness. This is not simply otitis media that needs oral antibiotics; it needs urgent evaluation for a possible bony or intracranial complication.
I would obtain the physical examination and vital signs immediately, start IV antibiotics rather than oral therapy, and arrange urgent ENT consultation, since surgical drainage or mastoidectomy may be needed depending on how she responds to medical treatment.
Build the presentation
Give every sentence one job
A presentation is a compressed clinical argument, not a chart read aloud. These six moves keep the facts connected to your reasoning.
Opening one-liner
Name the untreated infection and the red-flag findings together
“Mitchell is a 4-year-old girl with untreated acute otitis media who now has protrusion of her right outer ear and redness and tenderness over the mastoid bone behind it.”
Why it belongs: Naming the untreated antecedent ear infection alongside the ear protrusion and mastoid tenderness in the opening sentence signals a complication, not routine otitis media.
This is a 4-year-old with an ear infection and some swelling.
She has untreated acute otitis media with new ear protrusion and postauricular redness and tenderness.
Why: Naming the specific red-flag findings, not just 'swelling,' is what should prompt urgent escalation.
History of present illness
Give the severity and progression as described
“Her ear pain and high fever have continued from an ear infection that was not treated, and her caregiver now reports the outer ear looking pushed forward with visible swelling and tenderness behind it, worried about serious complications and a prolonged recovery.”
Why it belongs: The progression from an untreated infection to new anatomic displacement of the ear is the specific historical thread that should raise concern for a complication rather than a simple flare of otitis media.
Her ear infection got worse.
Her untreated ear infection has progressed to visible ear displacement and postauricular swelling.
Why: Naming the specific progression to anatomic displacement is far more informative than 'got worse.'
Relevant background
State what background is and is not known
“She has no significant chronic medical history documented, and the fact that her original ear infection went untreated is itself an important part of the story here.”
Why it belongs: Highlighting that the antecedent infection was untreated, rather than treated-but-failing, is relevant context for both the diagnosis and any counseling about early treatment of otitis media.
Nothing else significant in her history.
Her original ear infection was untreated, which is directly relevant to why this complication may have developed.
Why: Connecting the history to its relevance is more useful than a generic 'unremarkable.'
Objective data
State plainly that objective confirmation is not yet available
“Vital signs and a confirmatory physical examination, including formal assessment of the ear displacement and mastoid tenderness, have not yet been documented in this simulation, so I cannot confirm severity or complications from the history alone.”
Why it belongs: This is more clinically honest than assuming a fever level or the degree of swelling from the caregiver's description alone; mastoiditis and its complications must be assessed directly, not inferred.
She probably has a moderate fever and some swelling.
Vital signs and a confirmatory exam are not yet documented, so I cannot grade severity from the history alone.
Why: The source contains no vitals or exam confirmation yet, so the preferred wording separates known history from unknown severity.
Assessment
Name the leading diagnosis and its urgency
“My leading diagnosis is acute mastoiditis complicating untreated otitis media, based on the ear protrusion and postauricular swelling and tenderness. This is not simply otitis media that needs oral antibiotics; it needs urgent evaluation for a possible bony or intracranial complication.”
Why it belongs: Explicitly stating that this is not managed like uncomplicated otitis media prevents the common and dangerous error of prescribing oral antibiotics alone for a suspected mastoid complication.
She has a bad ear infection.
This is acute mastoiditis complicating otitis media, needing urgent evaluation, not oral antibiotics alone.
Why: Naming the specific complication and its different management pathway is the key safety point.
Plan
State the escalation and referral needed
“I would obtain the physical examination and vital signs immediately, start IV antibiotics rather than oral therapy, and arrange urgent ENT consultation, since surgical drainage or mastoidectomy may be needed depending on how she responds to medical treatment.”
Why it belongs: Naming IV antibiotics and urgent ENT referral together, rather than one alone, reflects the actual escalation pathway for this diagnosis compared with uncomplicated otitis media.
I'll start antibiotics and refer her to ENT.
I would start IV antibiotics rather than oral therapy and arrange urgent ENT consultation for possible surgical drainage.
Why: Naming the route of antibiotics and the possibility of surgery shows a more complete escalation plan.
Do not fill the blanks
Say what has not yet been established
Real presentations often happen before the chart is complete. A brief, explicit limitation is safer and more credible than a polished invention.
Vital signs and a confirmatory exam
Say: “Vital signs and a confirmatory physical exam are not yet documented in this simulation, and I would obtain them immediately.”
Do not describe her fever or the degree of swelling as mild or moderate without measuring or examining it directly.
Imaging for intracranial or bony complications
Say: “Imaging such as a CT of the temporal bones is not part of this simulation and would be obtained urgently if there is any suspicion of a bony or intracranial complication.”
Red flags such as severe headache, neck stiffness, or confusion would make imaging urgent rather than optional.
Clinical compression
What leads, what stays, and what can wait?
| Source detail | Decision | Reason |
|---|---|---|
| Ear protrusion and postauricular redness, swelling, and tenderness | Lead | These specific findings are the red flags that distinguish mastoiditis from uncomplicated otitis media. |
| Untreated antecedent acute otitis media | Lead | This is the precipitating history that explains why the complication developed. |
| No significant chronic medical history | Compress | Brief context, mainly relevant to confirm there is no other complicating condition. |
| High fever and severe ear pain | Include | These support the severity of the underlying infection, though exact values are not yet documented. |
| Need for IV antibiotics and urgent ENT referral | Lead | This is the actionable management difference from uncomplicated otitis media and belongs prominently in the plan. |
After the presentation
Likely attending questions
Answer the question first, then give the evidence. If the source case does not contain the answer, say what you would verify.
Why can't oral antibiotics be tried first, like for regular otitis media?
Once mastoiditis is suspected from findings like ear displacement and postauricular swelling, the risk of bony destruction and intracranial spread means IV antibiotics and urgent specialist evaluation are used instead of stepping up gradually from oral therapy.
What would make you escalate to emergency imaging right now?
Severe headache, neck stiffness, repeated vomiting, confusion, or facial weakness would all be red flags for an intracranial complication and would prompt urgent imaging and escalation rather than waiting for the standard evaluation to proceed stepwise.
How do you know this isn't just severe otitis media without mastoid involvement?
The specific findings of ear protrusion and postauricular swelling and tenderness are what distinguish mastoid involvement from otitis media confined to the middle ear, though a formal exam and any imaging are still needed to confirm the extent.
Self-check

- Do not assume fever severity or exam findings without direct assessment.
- Name the diagnosis as different in management from uncomplicated otitis media.
- State IV antibiotics, not oral therapy, as part of the plan.
- State that urgent ENT referral is arranged.
- Name the intracranial red flags that would prompt emergency imaging.
- State what vital signs and exam findings are still needed.
Common presentation problems
Repair the habits that make a case hard to follow
Treating this like routine otitis media with oral antibiotics
Repair: State explicitly that this needs IV antibiotics and urgent ENT evaluation.
Assuming vital signs are normal because none were mentioned
Repair: State that vital signs are not yet documented and need direct measurement.
Omitting intracranial red flags from the discussion
Repair: Name the specific symptoms that would prompt emergency imaging.
Describing the ear findings vaguely as 'swelling'
Repair: Name the specific protrusion and postauricular location, which are the actual red flags.
Frequently asked questions
Oral case presentation questions
Do I need to mention mastoidectomy in the initial presentation?
Yes, briefly, noting that it may be needed depending on response to medical treatment, without committing to it as a certainty before ENT evaluation.
How is mastoiditis diagnosed if imaging isn't done yet?
Initial suspicion is clinical, based on findings like ear protrusion and postauricular swelling in the setting of otitis media; imaging is used to assess extent and complications rather than to make the initial diagnosis.
How long should this presentation be?
This worked example targets about 70 seconds. A child with signs of an intracranial complication would need a more urgent, focused presentation.
