What Is the Nasal Release Technique? A Complete Guide

If you've been searching for answers about persistent concussion symptoms, chronic headaches, jaw pain, or sinus dysfunction, you may have come across the term Nasal Release Technique — or NRT. But what exactly is it, who performs it, and why is it getting so much attention in functional and integrative healthcare?

This guide covers everything you need to know about the Nasal Release Technique: its origins, how it works, the conditions it addresses, and what practitioners and patients can realistically expect.

What Is the Nasal Release Technique?

The Nasal Release Technique (NRT) is a manual therapy approach that uses a small, finger-cot balloon — inserted briefly into the nasal passage — to gently mobilize the cranial bones surrounding the nasal cavity. The balloon inflates for less than a second, creating a momentary pressure release that helps restore mobility to the cranial sutures (the joints between the bones of the skull) and reopens restricted nasal passages.

The goal is not simply to clear congestion. The deeper purpose is to restore proper airflow, improve drainage through the lymphatic and glymphatic systems, and reestablish the subtle rhythmic movement of cerebrospinal fluid through the cranial vault.

When cranial bones become restricted — whether from an old head injury, a difficult birth, dental work, or accumulated trauma — the brain's ability to drain waste, regulate pressure, and recover from injury is compromised. NRT addresses these restrictions at their structural source.

A Brief History of the Technique

The origins of NRT trace back to 1947, when Dr. Joseph Janse, DC, published the first article describing cranial adjustment through the nasal passage using a finger cot attached to a blood pressure bulb. He called the procedure Nasal Specific.

Over the following decades, chiropractors and naturopathic physicians continued refining and teaching the approach. Dr. J.R. Stober, a chiropractor and naturopath, is widely credited with popularizing the method at Western States Chiropractic College in Oregon. The technique passed from practitioner to practitioner largely outside mainstream medicine.

Cynthia Stein, PT, M.Ed., who developed the NRT training program at Conquer Concussion, has refined this approach specifically for licensed healthcare practitioners working with concussion, TBI, TMJ dysfunction, and chronic sinus conditions. Her online training program makes NRT certification accessible to physical therapists, chiropractors, dentists, and other licensed providers nationwide.

How Does the Nasal Release Technique Work?

To understand how NRT works, it helps to understand the anatomy of the cranial vault.

The skull is not a single rigid bone. It is a collection of 22 bones joined by fibrous joints called sutures. These sutures retain slight mobility throughout life. That mobility matters because each nasal breath creates a small change in intracranial pressure that helps circulate cerebrospinal fluid (CSF) — the fluid that cushions, nourishes, and cleans the brain.

When the cranial bones become restricted — jammed from physical trauma, birth injury, or chronic postural stress — this rhythmic pressure regulation is disrupted. CSF flow slows. The glymphatic system (the brain's waste-clearance network) stagnates. Metabolic waste builds up instead of draining. This is one of the key mechanisms behind why concussion symptoms can persist long after the initial injury.

The nasal cavity acts as a mechanical key to this system. Because the sphenoid bone — one of the most central and influential bones in the cranial vault — is accessible through the nasal passage, gentle pressure applied there can release restrictions across the entire cranial base.

During an NRT session, a lubricated balloon is guided through the nasal passage to one of the six paired nasal turbinates (three on each side). It is inflated briefly — typically less than a second — creating a gentle, controlled release. Most patients report immediate sensations of opening, warmth, a sense of pressure releasing behind the eyes, and noticeably improved nasal airflow.

What Conditions Does NRT Address?

The Nasal Release Technique is not a single-symptom treatment. Because it works at the level of the cranial structure, it has broad applications across conditions that share a common root: restricted cranial mobility, impaired drainage, and compromised airway function.

• Post-Concussion Syndrome: NRT helps address the structural aftermath of head injury by restoring cranial suture mobility and improving glymphatic drainage — the mechanisms that standard concussion protocols often leave untreated.

• Chronic Headaches and Migraines: Many chronic headaches have a structural component related to cranial bone restriction, sinus pressure, and impaired CSF flow. NRT addresses these root mechanisms directly.

• TMJ Dysfunction: The temporomandibular joint is intimately connected to the sphenoid bone and the surrounding cranial structure. NRT practitioners frequently see significant TMJ improvements alongside cranial release.

• Sinus Dysfunction and Chronic Congestion: NRT physically opens the nasal passages and restores drainage of the paranasal sinuses.

• Sleep Apnea and Airway Restriction: Narrow nasal airways contribute to obstructive sleep patterns. NRT can improve overnight breathing quality.

• Dizziness and Vestibular Symptoms: Compression of the cranial base affects the inner ear. Many practitioners observe that NRT reduces dizziness, tinnitus, and vestibular instability.

What Does the Research Say?

A 2023 review in StatPearls on balloon sinuplasty found significant patient improvement in airflow, sinus drainage, and symptom reduction using the same basic principle: restoring patency through controlled balloon dilation. The principle underlying NRT is mechanistically similar, applied at the cranial level.

Research from the University of Virginia (Louveau et al., Nature, 2015) established the existence of lymphatic vessels lining the dural sinuses of the brain — a finding that provides direct scientific support for interventions that restore cranial and lymphatic mobility.

Research on the glymphatic system (Ferrara et al., International Journal of Molecular Sciences, 2022) demonstrated that impaired CSF flow after traumatic brain injury disrupts the brain's waste-clearance system at every level — and that restoring structural conditions that support CSF flow is essential to recovery.

Is the Nasal Release Technique Safe?

When performed by a trained, licensed practitioner, NRT is considered safe and minimally invasive. The balloon used is the same size as a fingertip, and the inflation duration is brief. Most patients experience mild discomfort described as temporary pressure, followed by immediate relief.

Contraindications include active nasal infection, recent nasal surgery, unstabilized facial fractures, and uncontrolled bleeding disorders. A thorough health intake is standard practice before any NRT session.

How Can I Learn the Nasal Release Technique?

Nasal Release Technique training is available through Conquer Concussion's online certification program, led by founder Cynthia Stein, PT, M.Ed. The program was designed specifically for licensed practitioners — physical therapists, chiropractors, dentists, occupational therapists, osteopaths, and naturopathic physicians.

The virtual format means you can complete the certification from anywhere, on your schedule. The program includes a comprehensive training manual, hands-on instructional materials, and direct teaching from the practitioner who developed the training curriculum.
