Treatment of Onychocryptosis (Ingrown Toenail)

Conservative Treatment Approaches

  • The American Academy of Dermatology recommends taping the nail fold away from the nail plate to separate the ingrown edge from underlying tissue for mild to moderate onychocryptosis 1, 2
  • Dental floss nail splinting, which involves inserting dental floss under the ingrown nail to separate the lateral nail edge from the underlying tissue, is a recommended conservative treatment approach 1, 2
  • Flexible tube splinting, where a plastic tube with a lengthwise incision is placed on the lateral edge of the nail to encapsulate it, is another conservative treatment option 1, 2
  • Antiseptic soaks, such as daily dilute vinegar soaks (50:50 dilution) to nail folds twice daily for 10-15 minutes, are recommended to reduce infection risk 1, 2
  • Topical povidone-iodine 2% can be applied twice daily to reduce inflammation and prevent infection, as suggested by the American Academy of Dermatology 1, 2, 3
  • Mid to high-potency topical corticosteroid ointment can be applied to nail folds twice daily to reduce inflammation in cases with edema, pain, or granulation tissue 1, 2
  • Topical timolol 0.5% gel can be applied twice daily under occlusion for granulation tissue (pyogenic granuloma) 1, 2, 3
  • Silver nitrate cauterization can be used for chemical cauterization of granulation tissue 1, 2, 3

Surgical Treatment Approaches

  • Surgery is indicated for severe (grade 3), recurrent, or treatment-refractory onychocryptosis, according to the American Academy of Dermatology 1, 2, 3
  • Scoop shave removal with hyfrecation can be used for granulation tissue removal 1, 2
  • Acrylic treatment with gutter splint can be used for structural correction 1, 2
  • Intralesional triamcinolone acetonide can be used for recurrent or severe cases with persistent granulation tissue 1, 2

Important Caveats

  • Reassessing after 2 weeks is crucial, and if reactions worsen or do not improve with conservative treatment, surgical intervention is necessary 3
  • Avoiding cutting nails too short is essential, as it is a common predisposing factor; nails should be trimmed straight and not too short 3
  • Wearing comfortable, well-fitting shoes and cotton socks can help prevent recurrence 3
  • Podiatry referral should be considered for preventive correction of nail curvature in recurrent cases 3
