Treatment of Erythemic Lesions on the Roof of the Mouth and Buccal Mucosa
Topical corticosteroids should be used as first-line treatment for erythemic lesions on the roof of the mouth and buccal mucosa, specifically betamethasone sodium phosphate 0.5 mg dissolved in 10 mL water as a 3-minute rinse-and-spit preparation four times daily. 1, 2
First-Line Topical Treatments
- Apply topical steroids directly to the affected areas as the primary treatment approach for oral and palatal erythemic lesions 3, 1
- For localized lesions, clobetasol propionate 0.05% mixed in equal amounts with Orabase can be applied directly to the affected areas daily 1, 2
- Gelclair mucoprotectant gel applied three times daily forms a protective coating over ulcerated surfaces, reducing pain and promoting healing 1
- White soft paraffin ointment should be applied to the lips every 2 hours if they are also affected 1
Pain Management
- Benzydamine hydrochloride oral rinse or spray should be used every 3 hours, particularly before eating to reduce pain and discomfort 1
- For more severe pain, topical anesthetic preparations such as viscous lidocaine 2% can be applied up to 3-4 times daily 1
- Follow the WHO pain management ladder for progressive pain management if topical treatments are insufficient 2
Oral Hygiene Measures
- Clean the mouth daily with warm saline mouthwashes to reduce bacterial colonization and promote healing 1
- Use antiseptic oral rinses twice daily, such as 0.2% chlorhexidine digluconate mouthwash to prevent secondary infection 1, 3
- For patients on targeted therapies, saline-containing mouthwashes should be used instead of plain water due to the higher risk of microbial burden 3
- Maintain a daily oral hygiene routine, including brushing teeth and gums four times daily with a soft brush 3
Treatment for Secondary Infections
- If candidal infection is suspected (common secondary infection in oral lesions), treat with Nystatin oral suspension 100,000 units four times daily for 1 week 1, 2
- Alternatively, miconazole oral gel 5-10 mL held in the mouth after food four times daily for 1 week can be used 1
- Monitor for signs of bacterial infection, particularly Staphylococcus aureus, which may require specific antimicrobial therapy 3
Second-Line Treatments for Refractory Cases
- Tacrolimus 0.1% ointment applied twice daily for 4 weeks for lesions that don't respond to topical corticosteroids 1, 2
- Consider intralesional triamcinolone injections in conjunction with topical clobetasol for persistent lesions 1, 2
- For highly symptomatic or recurrent ulcers, systemic corticosteroids may be necessary (prednisone/prednisolone 30-60 mg or 1 mg/kg for 1 week followed by tapering over the second week) 1, 2, 4
Management Based on Specific Diagnosis
- If the erythemic lesions are part of erythema multiforme, identify and treat the underlying cause (commonly herpes simplex virus or medication reaction) 5, 6
- For recurrent erythema multiforme associated with herpes simplex virus, prophylactic antiviral therapy should be considered 6
- If the lesions represent oral erythroplakia (red velvety patches), surgical excision is the treatment of choice due to high malignant transformation potential 7
Lifestyle Modifications
- Avoid painful stimuli including smoking, alcohol, spicy foods, hot foods/drinks, and acidic foods 3
- Maintain adequate hydration to keep the mouth moist 3
- Remove dentures before performing oral care and clean thoroughly; defer wearing dental prostheses until the lining tissues are healed 3
Common Pitfalls and Considerations
- Ensure proper diagnosis of the type of mouth lesion before initiating treatment, as different etiologies require different approaches 1
- For patients with recurrent lesions, consider underlying systemic conditions that may require additional treatment 2
- Be aware that erythemic lesions on the palate and buccal mucosa could represent more serious conditions like erythroplakia, which has a high risk of malignant transformation and requires biopsy 7
