Treatment of Psoriasis Affecting the Ears
For ear psoriasis, apply low-potency topical corticosteroids (such as 1% hydrocortisone) or calcipotriene combined with hydrocortisone for 8 weeks as first-line therapy, reserving intralesional triamcinolone acetonide injections for thick, treatment-resistant lesions. 1, 2, 3
Initial Topical Treatment Approach
The ears represent a challenging anatomic location requiring careful corticosteroid selection to avoid atrophy and telangiectasia. 1, 2
- Start with low-potency corticosteroids (1% hydrocortisone) or calcipotriene combined with hydrocortisone applied for 8 weeks as the preferred initial therapy for ear psoriasis 2
- This combination provides efficacy while minimizing corticosteroid exposure in this vulnerable area 2
- Apply twice daily to affected areas, rubbing in gently 1
- Maximum continuous treatment duration with low-potency corticosteroids is 4 weeks before transitioning to maintenance therapy 2
Critical safety consideration: Never use high-potency (class 1-3) or ultrahigh-potency corticosteroids on the ears, as this dramatically increases the risk of irreversible skin atrophy and telangiectasia. 1, 2 The thin skin of the ear is at particularly high risk for these adverse effects. 1
Alternative First-Line Options
- Tacrolimus (topical calcineurin inhibitor) is an excellent corticosteroid-sparing option for ear psoriasis, as it does not cause skin atrophy and is specifically recommended for facial and intertriginous areas 1, 2
- Calcitriol ointment (vitamin D analogue) can be used to avoid corticosteroid-related atrophy 2
- These agents are particularly valuable for patients requiring treatment beyond 4 weeks 1
Treatment-Resistant Ear Psoriasis
For localized, thick, or treatment-resistant ear lesions that fail to respond to topical therapy:
- Intralesional triamcinolone acetonide injection is highly effective for resistant ear psoriasis 1, 3
- Use triamcinolone acetonide at doses up to 20 mg/mL, injected every 3-4 weeks 1
- Injection volume varies based on lesional size and affected area 1
- This approach is specifically documented as effective for ear psoriasis resistant to other therapies 3
Maintenance Strategy After Initial Control
Once initial control is achieved with low-potency corticosteroids:
- Transition to weekend-only corticosteroid application with weekday vitamin D analogue therapy to minimize corticosteroid exposure while maintaining efficacy 4, 2
- Apply high-potency topical corticosteroid twice daily on weekends only, and vitamin D analogue twice daily on weekdays 4
- This intermittent regimen reduces the risk of skin atrophy while prolonging remission 4
Prevention and Patient Education
- Counsel patients to avoid picking and scratching the ears, as mechanical trauma is a significant trigger for ear psoriasis 3
- Emphasize careful cleansing without aggressive rubbing 3
- These preventive measures are essential, as approximately 18% of all psoriasis patients develop ear involvement at some point 3
Critical Pitfalls to Avoid
- Do not combine salicylic acid with calcipotriene simultaneously—the acidic pH inactivates calcipotriene and eliminates its effectiveness 1, 4, 5
- Do not prescribe unsupervised repeat prescriptions of any topical corticosteroid for ear use without regular clinical review 2
- Avoid abrupt withdrawal of topical corticosteroids, as rebound can occur (though frequency is variable) 1
- Do not use occlusive dressings on the ears, as this increases penetration and atrophy risk 6
When to Escalate Treatment
If ear psoriasis is part of moderate-to-severe disease (>5% body surface area, symptomatic, or inadequate response to localized therapy after 8 weeks), consider systemic therapy or phototherapy rather than intensifying topical treatment on the ears. 4, 5
