Brief Summary:
The trial evaluates the safety and efficacy of the olfactory mucosa-derived mesenchymal stem cells based therapy for the patients with chronic laryngeal and tracheal stenosis

Condition or disease Intervention/treatment Phase
Tracheal Stenosis Laryngeal Stenosis Mesenchymal Stem Cells Biological: Olfactory mucosa-derived mesenchymal stem cells Phase 1 Phase 2

Detailed Description:

Trial evaluating the safety and efficacy of olfactory mucosa-derived mesenchymal stem cells based therapy for the patients with chronic laryngeal and tracheal stenosis.

Mesenchymal stem cells are obtained from tissue biopsy of olfactory mucosa using explant method. Biomass of autologous mesenchymal stem cells in 10% human albumin solution is injected submucosally around and over the tissue after removal of a granuloma tissue during surgical intervention.
