Cranial Facial Release (CFR) is a balloon-assisted endonasal technique used by some chiropractors and other practitioners as part of a broader care approach. It involves the brief inflation of a small balloon within the nasal passage with the aim of helping open the airways and influence movement within the cranial and facial structures. According to the CFR website, it is used in connection with issues such as breathing disorders, sinus problems, snoring, sleep apnoea, migraines and some neurological symptoms. Treatment is usually provided over a series of visits.
