Occasionally, a fissure will occur on the lip.
- Conditions that are thought to predispose to this lesion are mouth breathing, sun, and wind.
- Rarely, adults may develop a chronic lip fissure secondary to irritation from contact with his misaligned anterior teeth.
A painful and persistent fissure of the lip in a child is typical.
Fissures often are colonized with bacteria, particularly Staphylococcus. Topical bacitracin ad lib for one week is usually sufficient. If there is inflammation of the lip, a topical steroid ointment may be helpful.
