Nasal Release Technique (NRT) — also known as Cranial Facial Release (CFR), Endonasal Technique, Nasal Cranial Release, or Bilateral Nasal Specific Technique — is a structural therapy that gently mobilizes the bones of the skull through the nasal passages. A small inflatable device is briefly inserted into a nasal passage and expanded for approximately three seconds, pressing outward against the bones lining the airway. This targeted pressure unlocks impactions in the cranial sutures — the joints between the 22 bones of the skull — restoring proper structural alignment, opening the nasal airway, and optimizing cerebrospinal fluid flow and neurotransmitter activity.

A concussion is not only a neurological event — it is a structural injury to the skull. The force of impact compresses the cranial sutures, restricting cerebrospinal fluid drainage, lymphatic clearance, and nasal airway function. Standard concussion care addresses neurological symptoms but often misses this invisible structural component — which is why so many patients plateau despite doing everything right. NRT directly addresses the cranial compression that standard care misses. By restoring internal alignment and flow, NRT allows the brain and nervous system to complete their natural recovery process. It is the structural missing link in post-concussion syndrome treatment.

Yes. NRT has been practiced by licensed healthcare practitioners for decades and is considered safe when administered by a trained, licensed provider. The procedure is typically pain-free. Most patients report a sensation of deep pressure followed by a feeling of release and improved airflow. Some patients hear or feel mild clicks and pops as the cranial bones shift — this is normal and expected. Possible temporary side effects include mild nasal drainage, brief soreness in the nasal passages, or a short-lived headache as the body adjusts to the structural change. These typically resolve quickly. Contraindications: Active bleeding disorders or a history of severe facial bone surgery. A comprehensive medical history should always be taken before treatment.

Most patients describe NRT as mild pressure rather than pain. The device is inserted briefly — approximately three seconds per nasal passage — and the sensation is one of internal pressure, often followed by a mild pop or click as the cranial bones shift. Many patients report that the procedure is far more comfortable than they expected. A significant number describe immediate relief of head pressure, improved nasal breathing, and a sense of lightness following treatment.

NRT has been used clinically to address a wide range of conditions rooted in cranial compression and restricted airway function: Post-Concussion Syndrome — chronic symptoms after traumatic brain injury Chronic Headaches & Migraines Sleep Apnea & Breathing Disorders Sinus Dysfunction & Chronic Congestion Vertigo & Balance Problems TMJ Dysfunction PTSD & Nervous System Dysregulation Brain Fog & Cognitive Difficulty Because NRT restores structural alignment and internal flow throughout the entire cranial system, it often produces improvement across multiple symptoms simultaneously. The nasal airway functions as a pressure regulator for the entire skull — when it’s restricted, everything downstream is affected.

Many patients report meaningful improvement after their first session. Because each person’s cranial compression pattern and history is different, the total number of sessions varies. Acute or recent concussions may respond quickly. Chronic or longstanding post-concussion syndrome, sleep apnea, or structural dysfunction typically requires a series of sessions to achieve lasting results. Your NRT practitioner will assess your individual presentation and discuss a realistic treatment timeline during your first appointment.

An NRT session typically begins with a brief structural assessment — often including an eye-tracking evaluation to identify patterns of cranial restriction before treatment. The treatment itself involves the practitioner inserting a small inflatable device into each nasal passage for approximately three seconds. The entire active procedure usually takes only a few minutes. Patients commonly notice changes in breathing, head pressure, and mental clarity almost immediately. Following treatment, practitioners may re-assess eye movement or nasal airflow to confirm the structural shift has occurred.

Conquer Concussion maintains an official directory of licensed practitioners who have completed NRT training under Cynthia Stein, PT, MEd. Visit conquerconcussion.com/find-nrt-practitioner to search for a certified NRT provider in your area. All listed practitioners have completed hands-on virtual training and are qualified to perform NRT in a clinical setting. Practitioners come from a wide range of disciplines, including physical therapy, chiropractic, dentistry, and naturopathic medicine.

Standard concussion rehab addresses the neurological and musculoskeletal systems — retraining the eyes, strengthening the neck, rebuilding tolerance to stimulation. NRT addresses the structural layer that standard protocols leave untouched: cranial bone mobility, nasal airway function, and the fluid dynamics that drive the brain's own waste-clearance system.

NRT should only be performed by a licensed healthcare provider who has completed formal NRT certification training. Eligible practitioners include physical therapists, chiropractors, dentists, osteopathic physicians, occupational therapists, and naturopathic physicians. All practitioners listed in the Conquer Concussion directory have completed training with Cynthia Stein, PT, M.Ed.

Recent sinus surgery is a contraindication for NRT — treatment should be postponed until the surgical site has fully healed and your surgeon has cleared you for manual therapy. A thorough health intake before your first session will identify any contraindications. Your NRT practitioner will review your history and ensure NRT is appropriate for your situation before proceeding.

Yes. Cranial structural restriction does not spontaneously resolve with time. Many patients who have had persistent post-concussion symptoms for years — sometimes a decade or more — experience significant improvement with NRT. The structural changes from the original injury remain addressable regardless of when they occurred.
