Evaluation and Management of Cheilitis
Immediate Classification Required
The first step is to determine whether you are dealing with angular cheilitis (affecting the corners of the mouth) or other forms of cheilitis (affecting the vermillion border and lip surface), as these require completely different treatment approaches. 1, 2
Angular Cheilitis: First-Line Treatment
For angular cheilitis, initiate combination therapy with a topical antifungal plus corticosteroid (hydrocortisone 1% with miconazole 2% or clotrimazole 1%) applied 2-3 times daily for 1-2 weeks. 1 This addresses both the Candida infection and inflammatory components simultaneously. 1
Specific product options include:
- Daktacort (hydrocortisone 1% + miconazole 2%) 1
- Canesten HC (hydrocortisone 1% + clotrimazole 1%) 1
- Use cream formulation if the lesion is weeping/moist; use ointment if dry 1
Critical concurrent measures for angular cheilitis:
- Evaluate and correct ill-fitting dentures immediately—this is essential for resolution 1
- Remove dentures as often as possible during acute phase 1
- Soak dentures in 0.2% chlorhexidine solution for 10 minutes before reinsertion 1
- Apply white soft paraffin ointment to lips every 2-4 hours 1
- Use alcohol-free mouthwash to avoid mucosal irritation 1
- Avoid petroleum-based products chronically—they promote dehydration and create an occlusive environment favoring infection 1
If no improvement after 2 weeks, prescribe systemic fluconazole 100 mg daily for 7-14 days. 1, 2 This is particularly important for immunocompromised patients, who should receive systemic therapy earlier in the algorithm. 1
Evaluate for underlying systemic conditions:
- Check for diabetes, immunosuppression 1
- Screen for nutritional deficiencies (riboflavin, iron, vitamin B12) 2, 3
- Review medications that may contribute 1
Actinic Cheilitis: Definitive Treatment
For extensive actinic cheilitis, ablative laser vermilionectomy or CO2 laser ablation is the first-line treatment, providing the highest cure rates with lowest recurrence and best cosmetic outcomes. 4 This is the National Comprehensive Cancer Network's top recommendation for this premalignant condition. 4
Alternative options for actinic cheilitis:
- Topical 5-fluorouracil (though it fails to achieve complete histologic clearance) 4
- Topical imiquimod 4
- Photodynamic therapy 4
- Cryosurgery 4
- Destructive techniques are appropriate only for localized, not diffuse disease 4
Critical considerations for actinic cheilitis:
- Immunocompromised patients require more aggressive treatment to prevent progression to squamous cell carcinoma 4
- Biopsy any lesion with atypical appearance or not responding to appropriate therapy to rule out invasive disease 4
- Topical therapies require weeks of cyclical application 4
- Ingenol mebutate has the shortest treatment duration (3 days), which may improve adherence 4
Contact/Eczematous Cheilitis
For suspected irritant or allergic contact cheilitis:
- Identify and eliminate the offending agent (lip products, dental materials, foods) 5, 3
- Apply topical corticosteroids (mild to moderate potency) 5
- Consider patch testing if allergic etiology suspected 5
Infectious Cheilitis (Non-Angular)
For herpes simplex or candidiasis affecting the vermillion:
- Herpes: Oral antivirals (acyclovir, valacyclovir) 3
- Candidiasis: Topical or systemic antifungals depending on severity 3
Common Pitfalls to Avoid
Do not use petroleum jelly chronically on lips—it promotes mucosal dehydration and increases secondary infection risk. 1
Do not perform bronchoscopic biopsy routinely for small airway disease in Sjögren's patients with cheilitis symptoms. 6 However, if evaluating for Sjögren's syndrome in patients with angular cheilitis, ask specifically about painful sores or red patches at the corners of the mouth. 6
Do not assume all cheilitis is benign—actinic cheilitis can progress to squamous cell carcinoma, particularly in immunocompromised patients. 4
Do not treat empirically beyond 2 weeks without reassessment—reevaluate diagnosis and compliance if no improvement. 1, 2
