title: Q-switched ruby laser in the treatment of labial melanotic macules.
abstract: OBJECTIVE
  The term, labial melanotic macule, refers to a benign entity. The Q-switched ruby laser (QSRL) has been used to treat such lesions but the numbers are small with relatively short follow-up.
  
  
  METHODS
  Eight patients were treated with single pulses of the QSRL (694 nm, 20 nsec pulse duration, and 5 mm spot size) at 6.5 J/cm(2). Patients were followed-up for a maximum of 24 months to assess for recurrence.
  
  
  RESULTS
  Five patients cleared with a single pulse of the QSRL, while three required a second treatment session. There were no side-effects reported. At follow-up, there was no recurrence of pigment.
  
  
  CONCLUSIONS
  Treatment of labial melanotic macules with the QSRL produces excellent cosmetic results. No new pigment was detected at follow-up.
