Epistaxis v3
Presentation · PPTX
What's new in v3
Design overhaul:
- Max 4–5 bullets per slide — no crowding
- 7 real medical images embedded (all loaded successfully)
- Dark navy + rich card backgrounds with coloured accent borders
- Generous breathing room — text never fights with images
Images included:
| Slide | Image |
|---|---|
| 1 — Title | Lateral wall of the nose (anatomical photo) |
| 3 — Blood Supply | External carotid artery schematic (Scott-Brown's ORL) |
| 4 — Kiesselbach's | Lateral nasal wall showing turbinates |
| 5 — Posterior / Woodruff's | Endoscopic photo of Woodruff's plexus (Scott-Brown's) |
| 10 — Management | Management algorithm flowchart (Scott-Brown's) |
| 13 — Surgical | Two surgical intraop photos: ethmoidal artery approach + titanium clips on AEA (Scott-Brown's) |
Slide restructure (18 slides, less cramped):
- Title
- Definition & Epidemiology — 4 stat blocks + 6 facts
- Blood Supply — schematic + 3 artery cards
- Kiesselbach's Plexus — anatomy + contributing vessels
- Posterior/Woodruff's Plexus — endoscopy photo
- Anterior vs Posterior comparison table
- Local Causes — icon cards (6 tiles)
- Systemic Causes — icon cards (6 tiles)
- Clinical Assessment — 4 clean panels
- Step 1–2: First Aid & Cautery + flowchart
- Step 3: Nasal Packing (anterior vs posterior)
- Tranexamic Acid — mechanism + 3 evidence cards
- Surgical Options — 2 intraop photos + summary
- HHT — genetics + management
- Juvenile Angiofibroma
- Anticoagulated Patient
- Key Takeaways — 8 numbered pearls
- References
Why is the slides looking so congested . You can extend the content to upto 2 slides each
I'll completely rebuild this with a clean, spacious design — each topic gets room to breathe, large images, minimal text per slide.

Epistaxis v4
Presentation · PPTX
What's fundamentally different in v4
The core change — breathing room:
- Max 3 bullet points per slide — enforced without exception
- Large font: 16–17 pt body text — nothing small
- Every slide has one large image taking up 40–55% of the slide area
- Topics are spread across 2 full slides instead of being squeezed into one
26 slides — structured breakdown:
| # | Slides | What's on each |
|---|---|---|
| 1 | Title | Full-height anatomy photo, 3 stat badges |
| 2–3 | Epidemiology | Stats + definition / Patterns + anatomy image |
| 4–5 | Blood Supply | External carotid schematic / Kiesselbach's plexus |
| 6 | Posterior epistaxis | Large endoscopic photo of Woodruff's plexus |
| 7 | Comparison table | Anterior vs posterior — spacious table |
| 8–9 | Aetiology | Local causes / Systemic causes — icon tile grid |
| 10–11 | Assessment | ABC & history / Examination technique + endoscopy photo |
| 12–16 | Management | Step 1–2 (first aid) / Cautery / TXA / Anterior pack / Posterior pack |
| 17–18 | Surgery | Two real intraop photos (ethmoidal artery) / All options |
| 19–20 | HHT | Pathophysiology + Curaçao criteria / Treatment |
| 21 | JNA | Features + "never biopsy" prominent warning |
| 22 | Anticoagulated | 3-column approach panel |
| 23 | Discharge advice | 6-tile icon grid |
| 24–25 | Takeaways | 4 pearls per slide — large, readable |
| 26 | References | 9 sources |
