Assessment
Primary outcomes
Occurrence and details of all adverse events, those related to the investigative product, and defect of the product are evaluated to validate safety.
Key secondary outcomes
Improvement of stenosis by sectional image of CT scan, evaluation of fixation and detachment of transplants and epithelial regeneration by ultrasonography, dynamic evaluation of stenosis by endoscopic examination, evaluation of ventilation function by respiratory function test, evaluation of respiratory function by arterial blood gas analysis, amount of change in everyday life operability by questionnaire on everyday life operability, cosmetic satisfaction, change in daily activity, change in depressiveness, evaluation of the cartilage collection site, and evaluation of fixing and cartilage maturation by MRI are used exploratory to evaluate the efficacy.
