How should nasal mucosal fissures be managed?

Management of Nasal Mucosal Fissures

For nasal mucosal fissures (fissuring inside the nostrils), maintain nasal moisture with regular saline irrigation and apply topical emollients, while directing intranasal corticosteroid sprays away from the septum to prevent further mucosal erosion.

Initial Assessment and Underlying Causes

First, examine the nasal septum carefully to identify the extent of fissuring and rule out concerning etiologies. Look specifically for:

• Septal perforation - which suggests intranasal drug abuse (particularly cocaine), overuse of topical decongestants, previous surgery, or systemic granulomatous diseases like sarcoidosis 1
• Crusting on inflamed mucosa - may indicate atrophic rhinitis or systemic diseases 1
• Medication history - particularly intranasal corticosteroid use and topical decongestants

The presence of fissures often results from chronic dryness, mechanical trauma from nose-picking, or improper intranasal medication technique.

Primary Treatment Strategy

Nasal Humidification (First-Line)

• Nasal saline sprays or irrigations throughout the day to maintain moisture and prevent crusting 2
• This is the cornerstone of management for preventing and healing mucosal fissures
• Keeping the nose humid facilitates healing of raw mucosal surfaces 2

Topical Emollients

• Apply water-based or petroleum-based ointments to the affected areas
• These create a protective barrier and promote healing
• Can be applied 2-3 times daily, particularly at bedtime

Medication Adjustment

If the patient uses intranasal corticosteroids:

• Instruct patients to direct sprays away from the nasal septum to prevent repetitive direct application 1
• The nasal septum should be periodically examined to ensure no mucosal erosions are present, as these may precede development of septal perforations 1
• Consider temporarily discontinuing or reducing frequency if erosions are present

Management of Rhinitis Medicamentosa

If fissuring is associated with topical decongestant overuse:

• Recognize that patients may develop rhinitis medicamentosa in as little as 3 days with regular use 1
• Discontinue topical decongestants immediately
• Substitute with intranasal corticosteroids for congestion control
• Expect rebound congestion for 5-7 days during withdrawal

Treatment of Atrophic Rhinitis

If examination reveals atrophic changes with crusting and fissuring 1:

• Continuous nasal hygiene with saline or sodium bicarbonate solution irrigations
• Periodic debridement of crusts if necessary
• Topical antibiotics (such as mupirocin) added to lavage solution for purulent secretions
• Systemic antibiotics only when acute infection is present

Red Flags Requiring Further Investigation

Refer for specialist evaluation if:

• Septal perforation is identified
• Systemic symptoms suggesting granulomatous disease (sarcoidosis, Wegener's granulomatosis)
• History of intranasal drug abuse
• Persistent bleeding despite conservative measures
• Progressive enlargement of fissures or erosions

Common Pitfalls to Avoid

1. Improper spray technique - The most common cause of iatrogenic septal fissuring is directing intranasal corticosteroid sprays directly at the septum rather than laterally toward the turbinates 1

2. Overlooking medication-induced causes - Always review use of topical decongestants, which can cause mucosal damage with chronic use 1

3. Ignoring underlying systemic disease - Persistent or progressive fissuring warrants evaluation for granulomatous diseases 1

4. Continuing intranasal corticosteroids despite erosions - While nasal septal perforations from intranasal corticosteroids are rare, mucosal erosions suggest increased risk and warrant temporary discontinuation 1

Long-term Management

• Continue daily saline irrigation indefinitely to maintain mucosal health
• If intranasal corticosteroids are necessary, ensure proper lateral spray technique
• Monitor the septum periodically for healing or progression
• Address any underlying rhinitis (allergic or nonallergic) to reduce inflammation and need for aggressive medication use

The key principle is maintaining adequate nasal moisture while eliminating mechanical or chemical irritants that perpetuate mucosal injury 2, 1.
