title: The KTP laser: an emerging tool in pediatric otolaryngology.
abstract: OBJECTIVE
  To report the frequency and spectrum of use of the potassium titanyl phosphate (KTP) laser in a tertiary referral pediatric otolaryngology practice and to focus on a novel use for the KTP laser which has not previously been described in the literature.
  
  
  METHODS
  A retrospective chart review of the operative log database of a pediatric otolaryngologist in a tertiary referral setting over a seven year period.
  
  
  RESULTS
  Out of 2886 cases, a total of 49 (1.7%) involved the use of the KTP laser. These included 7 otologic cases, 3 laryngeal cases, 31 subglottic/tracheal cases, 1 esophageal case and 7 nasal cases. One of these cases involved a previously unreported use of the KTP laser, closure of a tracheo-esophageal fistula (TEF).
  
  
  CONCLUSIONS
  The KTP laser is an important operative tool in pediatric otolaryngology and new uses for this laser continue to emerge. One of these, KTP closure of a TEF offers pediatric otolaryngologists the potential for significant changes in management of this congenital problem with reduced surgical morbidity. Familiarity with the KTP laser and expertise in its use and applications is essential in providing state-of-the-art care to pediatric otolaryngology patients in a tertiary referral center.
