Local therapy includes gentle cleansing and the application of bland ointment or silver sulfadiazine ointment to keep the area moist. Antibiotics may be utilized if overt signs of infection are noted. In many cases, other treatment is not necessary because the erosions and the ulcerations almost always heal on their own. Recently, a variety of specialized dressing materials have been developed and used.
Surgical repair is not usually indicated if the defect is small. Recovery is generally uneventful, with gradual epithelialization and formation of a hairless, atrophic scar over several weeks. Small underlying bony defects usually close spontaneously during the first year of life. Surgical repair of large or multiple scalp defects may require excision with primary closure, if feasible, or the use of tissue expanders and rotation of a flap to fill the defect. On occasion, skin and bone grafts may also be required.
