Objectives Recurrent respiratory papillomatosis is often treated with in‐office laser procedures using a potassium titanyl phosphate (KTP) laser transmitted through a laser fiber. Although effective, this procedure has notable downsides, including the possibility of transmitting human papillomavirus (HPV) in the smoke plume and the high cost of these single‐use fibers. The objective of this study is to determine if HPV can be detected on a laser fiber after use, with or without sterilization. Methods Twelve patients with laryngeal papillomas were treated with KTP laser energy transmitted via a KTP fiber. Ten fibers were sterilized in CIDEX (ASP, Irvine, California), a glutaraldehyde disinfectant, for 12 minutes, whereas two fibers were left unsterilized. Human papillomavirus DNA amplification was done on all 12 fiber samples with real‐time polymerase chain reaction (PCR) using general primer mediated 5+ and 6+. Human papillomavirus genotyping detection was done using type specific probes and/or Sanger sequencing. Results Over 27 strains of HPV were not detected on KTP fibers after use, with or without sterilization. Conclusion Human papillomavirus was undetectable by PCR on KTP laser fibers that were sterilized or unsterilized after use. Further studies are needed utilizing a transmission model to determine if HPV can be incubated from this fiber after sterilization. Level of Evidence NA. Laryngoscope , 128:926–928, 2018
