(A) Pre-operative situation of patient affected by bilateral external and internal nasal valve collapse with nasal obstruction produced by excessive resection during previous surgery. (B) Post-operative situation after 12 months of the same patient treated with condrocyte micro-grafts obtained by Rigeneracons^® (CE certified Class I) mixed with platelet-rich plasma (PRP) in solid form.
