title: Efficacy of 5-Aminolevulinic Acid Photodynamic Therapy in treatment of nasal inverted papilloma.
abstract: OBJECTIVE
  Evaluate the efficacy of 5-Aminolevulinic Acid Photodynamic Therapy (PDT) in medical treatment of nasal inverted papilloma (NIP).
  
  
  METHODS
  Three patients with nasal inverted papilloma were treated with 5-Aminolevulinic Acid Photodynamic Therapy at our department from April to September 2012. The efficacy and adverse effects of 5-Aminolevulinic Acid Photodynamic Therapy were evaluated during 6-8 months of follow-up medical examination.
  
  
  RESULTS
  After treated with 5-Aminolevulinic Acid Photodynamic Therapy, the nasal inverted papillomas were removed. No recurrence was found during the 6-8 months of follow-up medical examination. The major adverse effects were mild erosion, pain, and exudation.
  
  
  CONCLUSIONS
  5-Aminolevulinic Acid Photodynamic Therapy appears to be an effective treatment of nasal inverted papilloma. It can clear the papilloma lesions and is well tolerated by the patients.
