Radiation
Radiation
Radiotherapy reduces fibroblast activity and induces cellular apoptosis, inhibiting the recurrence of keloidal scars, and making it an effective adjuvant to surgical excision.93 Surgical excision is associated with recurrence rates, ranging between 45% and 100%, but this rate can be reduced to 10% via perioperative radiation.55 For a more extensive discussion of radiation therapy, see Chapter 37.
CONCLUSIONS
Acne is a common problem, and dermatologic surgeons may approach these patients in several ways. Options range from laser and light devices for primary acne lesions to scar revision, chemical peels, dermabrasion, and needling for acne scars. Further studies comparing the efficacy of various therapeutic modalities may help better determine an ideal treatment approach, though multimodality treatment options may ultimately provide the highest success rates.
