How to Close a Tracheostomy Site
In most patients, the tracheostomy stoma closes spontaneously within hours to days after decannulation, requiring no intervention; however, if the stoma persists beyond this timeframe, formal surgical closure becomes necessary. 1
Spontaneous Closure (First-Line Approach)
The vast majority of tracheostomy stomas will close on their own without surgical intervention. Based on recent prospective data, the median time to initial stoma closure is 5 days (range 2-9 days), with complete healing of the skin occurring at a median of 16 days (range 10-18 days) 2.
Factors That Delay Spontaneous Closure:
- Larger stoma size at decannulation
- Advanced age
- Diabetes mellitus
- Corticosteroid use
- Longer cannulation time (median 54 days in one cohort) 2
Immediate Post-Decannulation Management:
- Apply a simple dressing to the stoma site
- Keep the area clean with isotonic saline
- Change dressings as needed to prevent moisture accumulation
- Monitor for signs of infection or delayed healing
- No immediate intervention is required if the patient is breathing well and not hypoxic 3
Important caveat: During the first 12-36 hours after decannulation, rapid anatomic closure of the stoma can make emergency recannulation difficult if complications arise 1. Ensure the patient has a secure upper airway before proceeding.
Surgical Closure (When Spontaneous Closure Fails)
If the stoma fails to close spontaneously after several weeks, formal surgical closure is indicated 1.
Surgical Technique Options:
1. Simple Deepithelialization (Preferred for simplicity):
- Can be performed under local anesthesia
- Simpler and quicker than multilayer techniques
- Associated with no major complications in published series
- Lower complication rate compared to three-layer closures (0% vs 30%) 4
2. Advanced Technique (For long-term/permanent tracheostomies):
- Combines a turnover flap with medialization of fibroadipose tissue
- Followed by advancement skin flap closure
- Reported success rate with no major complications and minimal need for re-tracheostomy 5
- Particularly useful for stomas that have been present for extended periods
3. Three-Layer Closure (Traditional but higher complication rate):
- Historically used but associated with 30% complication rate
- Complications include: stridor, subcutaneous emphysema, pneumomediastinum, tracheal granuloma, hematoma, and respiratory arrest
- 4-5% may require reopening of the tracheostomy site 4
Clinical Algorithm for Stoma Closure
Step 1: After decannulation, observe for spontaneous closure
- Monitor stoma size every 8 hours initially
- Continue daily measurements until complete healing
- Expected closure: 2-9 days; complete healing: 10-18 days 2
Step 2: If stoma remains patent beyond 2-3 weeks:
- Assess for factors delaying closure (diabetes, steroids, infection)
- Optimize wound healing conditions
Step 3: If stoma persists beyond 4-6 weeks despite optimization:
- Refer for surgical closure
- Choose simple deepithelialization for most cases
- Reserve advanced techniques for large or long-standing stomas
Critical Pitfalls to Avoid
- Do NOT attempt blind manipulation of a fresh stoma—harm has resulted from inappropriate attempts when not required 3
- Do NOT perform formal closure immediately at decannulation unless specifically indicated (e.g., patient preference, immediate need for water-tight seal)
- Avoid petroleum-based products on the peristomal skin 1
- Be aware that patients may require re-tracheostomy later due to upper airway obstruction that was not adequately appreciated—this risk is minimized by performing endoscopic evaluation before decannulation 1
The evidence strongly supports a conservative "watch and wait" approach for the majority of patients, with surgical intervention reserved only for persistent stomas that fail spontaneous closure.
