Im 99% sure that the cause of ens is neurologic. Many people dont have hypertrofied turbinates and breath without having empty or other feelings. If an implant costs almost 10k I think 6 injections would have a much higher benefit for that price. Thats my advice. The only way of going for implants is if you are looking to almost close the airway in a way that the inferior turbinate wont contact with air. But even then I think the nose will re adjust and wont help..
