Cholesteatoma Surgery: Close the Incision Primarily
For cholesteatoma surgery, you should close the skin incision primarily with sutures rather than leaving it open to drain. The evidence overwhelmingly supports primary closure of clean surgical incisions, and cholesteatoma surgery—whether performed via canal wall-up or canal wall-down techniques—creates a clean surgical wound that should be closed in layers.
Incision Management
The surgical approach for cholesteatoma (mastoidectomy with or without tympanoplasty) creates a postauricular or endaural incision that should be:
- Closed in layers using sutures, staples, or tissue adhesive to approximate skin edges 1
- Not left open unless there is frank purulent contamination or infected tissue (which is not typical in cholesteatoma surgery)
The concept of delayed primary closure is reserved for contaminated/dirty wounds with purulent material 2, which does not apply to standard cholesteatoma surgery. Even in emergency abdominal surgery with contamination, delayed closure is only considered for "dirty incisions with purulent contamination" 2.
Postoperative Wound Care
Dressing Management
- Apply a standard surgical dressing immediately after closure—advanced dressings offer no benefit over standard dressings 1
- Keep the dressing undisturbed for at least 48 hours unless leakage occurs 1
- After 48 hours, the dressing can be removed as the wound becomes impermeable to microorganisms
- No evidence supports extending dressing time beyond 48 hours for infection prevention 1
Drain Considerations
- Do NOT place subcutaneous drains routinely 2
- High-quality evidence shows subcutaneous drains provide no advantage in preventing surgical site infections 2
- If dead space is a concern, use quilting sutures to obliterate it rather than placing drains 2
Antibiotic Management
Recent evidence from canal wall reconstruction surgery shows:
- Outpatient oral antibiotics are sufficient and non-inferior to intravenous antibiotics 3
- The infection rate with oral antibiotics is extremely low (0% in one study of 51 patients) 3
- No need for 24-48 hours of intravenous antibiotics as previously recommended
Monitoring for Complications
Inspect the wound if the patient develops:
- Fever >38.5°C or heart rate >110 bpm within the first few days 4
- Erythema extending >5 cm beyond wound margins 4
- Drainage or wound dehiscence
Early postoperative fever (first 48 hours) is rarely due to surgical site infection and usually has noninfectious causes 4. However, if systemic signs develop, examine the wound directly rather than manipulating it unnecessarily.
Common Pitfalls to Avoid
- Don't leave the incision open "to drain"—this is not indicated for clean cholesteatoma surgery and increases infection risk
- Don't use advanced/specialty dressings—they cost more without improving outcomes 1
- Don't place subcutaneous drains routinely—evidence shows no benefit 2
- Don't keep dressings on longer than 48 hours thinking it prevents infection—it doesn't 1
- Don't assume early fever means wound infection—it's usually from other causes in the first 48 hours 4
The key principle is that cholesteatoma surgery creates a clean surgical wound that should be managed like any other clean otologic procedure: primary closure, standard dressing for 48 hours, and oral antibiotics if indicated.
