Laryngeal stenosis is caused by various reasons and we are usually able to detect a cause in many cases. Occasionally we encounter a case without an obvious cause. Recently we observed such a case, and we suspected that chlorine detergent possibly caused it. The patient was a 66-year-old female whose main complaint was stridor. She had been using chlorine detergent everyday for about ten years. She had been diagnosed and treated for bronchial asthma because of the stridor. Subsequently, supraglottic stenosis was observed and it was caused by this lesion. There was no particular past history and no distinguishing pathological character in the stenosis lesion. The stenosis was removed by laryngo-fissure with a supra-hyoid approach while a surgical lumen was maintained using a core mold. She stopped using the detergent after the treatment. After sixteen months of follow-up since the operation, the patient has shown no evidence of recurrent disease.
