Airway stenosis is a rare, life-threating disease requiring the early establishment of management guidelines. However, because of its rarity, evidence concerning this pathology is sparse. To understand the actual situation in cases of pharyngeal, laryngeal and tracheal stenosis, a nationwide questionnaire survey is being conducted. Furthermore, a patient registry for cases of pharyngeal, laryngeal and tracheal stenosis is also being constructed for the prospective accumulation of guaranteed patient information. New evidences concerning airway stenosis is expected to be generated through these studies.

As a novel reconstructive implant, an in situ tissue regeneration-inducing artificial trachea made of polypropylene and collagen was developed in Japan. Clinical trials to validate the safety and efficacy of this artificial trachea have already been completed, and the early clinical application of this material is expected.
