| 5 | CSOM (7.9–7.10) – Safe vs Unsafe type comparison table | Purple vs Green |
| 6 | Chronic Non-Suppurative OM (7.11): ET Catarrh, Glue Ear, Atelectasis | Multi-colour |
| 7 | Otalgia (7.12–7.13) + Otorrhea (7.14–7.15) split layout | Red / Orange |
| 8 | Deafness (7.16–7.18) – 3 types + Tuning fork findings + Management | Cyan / Orchid / Green |
| 9 | Tinnitus (7.19–7.20) – Types, Causes, Ix, Management | Full column layout |

📄 What's Inside – 19 Pages | 1.3 MB | A4 Landscape | Dark Theme
9 Original Schematic Diagrams:
| Fig | Diagram | What it shows |
|---|---|---|
| 1 | Cross-Section of the Ear | External → Middle → Inner ear with all labelled structures, ossicular chain, cochlea spiral, semicircular canals, sound pathway arrow |
| 2 | Otoscopic TM Views ×3 | Normal TM (pearly grey, cone of light) / ASOM (bulging, red) / CSOM (central perforation) |
| 3 | ASOM 5-Stage Flowchart | Colour-coded boxes: Hyperaemia → Exudation → Suppuration → Resolution/Perforation → Complication |
| 4 | CSOM Safe vs Unsafe | Side-by-side TM diagrams with cholesteatoma in unsafe type |
| 5 | Audiogram | Conductive HL (air-bone gap, Rinne -ve) vs SNHL (parallel elevation, Rinne +ve) |
| 6 | Tuning Fork Tests | Rinne's + Weber's with visual fork diagrams and interpretation table |
| 7 | Peripheral vs Central Vertigo | 10-point comparison table in one diagram |
| 8 | CN VII Course + Bell's Palsy | Full nerve pathway flowchart, UMN vs LMN panel, Bell's Palsy details |
| 9 | Tympanograms A / B / C | Type A (normal), B (flat = glue ear), C (neg. pressure = ET catarrh) |
Note sections cover all 26 SLOs:
- Anatomy & Physiology (7.1–7.2) with Physiology pathway
- External Ear diseases (7.5–7.6) - OE, furunculosis, wax, neoplasm
- ASOM (7.7–7.8) with full 5-stage progression
- CSOM Safe & Unsafe (7.9–7.10) with cholesteatoma, complications, surgery
- Deafness types with audiogram interpretation (7.16–7.18)
- Tinnitus causes, types, management (7.19–7.20)
- Vertigo, BPPV, Meniere's, Acoustic Neuroma (7.21–7.25)
