Treatment of chronic lip fissures with carbon dioxide laser

Abstract 

Resurfacing of cutaneous tissue with carbon dioxide laser increases the amount and quality of collagen and elastin subepithelially. We used this technique to ablate 12 chronic lip fissures in one woman and 10 men. Five patients’ fissures had persisted for durations ranging from several months to seven years; the other six had fissures that split between one and five times annually, and took weeks or months to heal.

Ten fissures had re-epithelialised completely six weeks postoperatively, while in two cases the treatment was repeated. At mean long-term follow-up of 70 months (range 44–93) of 11 cases, eight had had no recurrence. One patient, whose fissure had healed at three months was lost to follow-up; one fissure had not improved; one had recurred less severely; and one had split only once, then healed quickly and not recur. Only one patient had postoperative discomfort that required analgesia, and one had a mildly raised scar.

This small series shows that this is a successful, safe technique with low morbidity, however, the technology is not always readily available.
