A 32-year-old man from rural Maharashtra presents with a 6-month history of foul-smelling ear discharge and conductive hearing loss. Otoscopy reveals a central perforation with mucopurulent discharge. Pure tone audiometry shows air-bone gap of 35 dB. CT temporal bone is normal with no evidence of ossicular erosion or cholesteatoma. What is the most appropriate next step in management?

Question

Accepted Answer

A. Aural toilet, topical antibiotic drops, and hearing aid trial; reassess after 3 months of conservative management. ## Management Strategy for Chronic Suppurative Otitis Media (CSOM) — Safe Type

### Clinical Context
This patient has **safe CSOM** (central perforation, no ossicular erosion, no cholesteatoma on imaging). The air-bone gap of 35 dB indicates conductive hearing loss from ossicular involvement or perforation itself.

### Stepwise Management Algorithm

  A[CSOM diagnosis confirmed]:::outcome --> B{Cholesteatoma or ossicular erosion?}:::decision
  B -->|Yes| C[Surgical intervention: Ossiculoplasty ± Mastoidectomy]:::action
  B -->|No| D[Conservative management first]:::action
  D --> E[Aural toilet + topical antibiotics]:::action
  E --> F[Hearing assessment + trial of hearing aid if needed]:::action
  F --> G[Review at 3 months]:::decision
  G -->|Persistent discharge| H[Consider tympanoplasty]:::action
  G -->|Dry ear, acceptable hearing| I[Continue conservative care]:::outcome
```

### Rationale for Conservative Management

**Key Point:**
In safe CSOM without ossicular erosion or cholesteatoma, the goal is to achieve a **dry ear** before considering ossiculoplasty. Ossiculoplasty is contraindicated in an actively draining ear because of poor graft take and infection risk.

**High-Yield:**
The sequence is: **Aural toilet → Topical antibiotics → Hearing aid trial → Reassess → Then ossiculoplasty only if ear remains dry and patient desires hearing improvement.**

### Components of Conservative Management

| Step | Rationale |
|------|----------|
| **Aural toilet** | Remove discharge, debris; allows topical agents to penetrate |
| **Topical antibiotics** (e.g., ciprofloxacin drops) | Fluoroquinolones are safe in perforated ears; reduce bacterial load |
| **Avoid water entry** | Prevent superinfection; advise cotton + vaseline during bathing |
| **Hearing aid trial** | Assess functional benefit before committing to surgery |
| **3-month reassessment** | Determine if ear has dried; if so, ossiculoplasty becomes an option |

**Clinical Pearl:**
Ossiculoplasty in an actively draining ear has graft failure rates >50%. Always achieve a dry ear first.

### When to Escalate to Surgery
- Persistent discharge despite 3 months of conservative care
- Recurrent acute exacerbations
- Patient desire for hearing improvement *and* dry ear achieved
- Evidence of ossicular erosion on repeat imaging
