Nasal valve collapse represents one of the most functionally devastating complications of rhinoplasty. Unlike aesthetic concerns that affect how you look, nasal valve collapse affects how you breathe—and for many patients, this is the primary reason they seek revision surgery.
If you find yourself constantly congested, unable to breathe through your nose during exercise, or noticing your nostrils "sucking in" when you inhale deeply, you may be suffering from nasal valve collapse. The good news is that this condition is highly treatable with the right surgical approach.
Understanding the Nasal Valve
The nasal airway has two valves that control airflow: the internal nasal valve and the external nasal valve. Together, they regulate how air moves through your nose during breathing.
The Internal Nasal Valve: This is the angle between the nasal septum (the wall between your nostrils) and the upper lateral cartilage. Normally, this angle measures between 10 and 15 degrees. When functioning properly, it allows smooth, laminar airflow. When compromised, it collapses inward during inspiration, creating turbulent airflow and significant obstruction.
The External Nasal Valve: This is the area around the nostril opening, supported by the lower lateral cartilages (alar cartilages). Weakness here causes the nostrils to collapse or narrow with each breath.
Understanding what can go wrong in rhinoplasty helps explain why valve collapse occurs and how it can be prevented or corrected.
What Causes Nasal Valve Collapse?
Nasal valve collapse after rhinoplasty has several potential causes:
- Over-resection of upper lateral cartilages: During hump reduction, if the surgeon removes too much of the upper lateral cartilage, the structural support for the internal valve is destroyed.
- Over-aggressive cephalic trimming: Removing too much of the lower lateral cartilages during tip refinement weakens the external valve.
- Lateral osteotomies placed too medially: When nasal bones are cut and moved too far inward, they can narrow the nasal passage.
- Scar contracture: As scar tissue forms and contracts, it can pull the nasal tissues inward, narrowing the airway over time.
If you have had cartilage grafting, your risk of valve issues may be different. Grafts can both cause and correct valve problems depending on their placement.
Recognizing the Symptoms
Patients with nasal valve collapse typically experience:
- Severe nasal obstruction, especially during exercise or deep breathing
- A whistling sound when inhaling through the nose
- Visible "sucking in" of the nasal sidewall or nostrils with inspiration
- Inability to breathe through the nose despite using decongestants or nasal sprays
- Poor sleep quality, snoring, or sleep apnea symptoms
- Chronic mouth breathing
- Fatigue from the effort required to breathe
If these symptoms sound familiar, you are not alone. Many of our revision patients come to us specifically for functional improvement after a primary rhinoplasty that left them unable to breathe properly. The patient journey for functional revision focuses first on restoring airway function.
The Cottle Maneuver: A Simple Self-Test
One way to check for internal nasal valve collapse is the Cottle maneuver. Here is how to perform it:
- Take a deep breath in through your nose and note how easily air flows.
- Using your finger, gently pull your cheek outward (away from your nose) on one side.
- Take another deep breath.
- If breathing becomes significantly easier with your cheek pulled outward, you likely have internal nasal valve collapse.
This maneuver works because pulling the cheek outward simulates the effect of spreader grafts—it widens the internal valve angle, allowing air to flow more freely. If you notice improvement, it is a strong indicator that you would benefit from surgical correction.
Surgical Treatment Options
At our practice, we offer several proven techniques for correcting nasal valve collapse, depending on the severity and specific anatomy of your case.
Spreader Grafts (The Gold Standard)
Spreader grafts are narrow, rectangular pieces of cartilage (typically 25-30mm long and 3-4mm thick) placed on each side of the septum. They push the upper lateral cartilages outward, permanently widening the internal valve. We have placed over 1,200 spreader grafts in revision cases, and the improvement in nasal breathing is often immediate—patients notice it the moment the splints come out.
Spreader grafts can be harvested from septal cartilage (when available), ear cartilage, or rib cartilage depending on your specific needs.
Butterfly Grafts
For patients with both internal and external valve collapse, butterfly grafts can be an excellent solution. This technique involves placing a curved piece of cartilage over the nasal tip, which acts like a spring to hold the sidewalls open. It is particularly effective for patients with weak cartilage or thin skin.
Lateral Crural Strut Grafts
For isolated external valve collapse (nostril collapse), lateral crural strut grafts reinforce the lower lateral cartilages. These thin strips of cartilage are placed along the weak areas of the alar cartilages, providing structural support without changing the aesthetic appearance of the tip.
Alar Batten Grafts
Alar batten grafts are small pieces of cartilage placed in the sidewall of the nose to prevent dynamic collapse during inspiration. They are particularly useful for patients with scarred or weakened tissue from previous surgeries.
What to Expect After Surgery
Most patients notice immediate improvement in their breathing once the nasal splints are removed at day 7-10. However, final functional results continue to improve over the first 3-6 months as swelling resolves and the grafts settle into position.
It is important to understand that swelling at month 3 can temporarily affect your breathing as well. Some patients report that their breathing feels slightly restricted during peak swelling phases—this is normal and resolves as the swelling subsides.
When to Seek Help
If you are struggling to breathe through your nose after rhinoplasty, do not wait. Functional issues rarely improve on their own. In fact, scar contracture can worsen valve collapse over time, making revision more complex.
We recommend waiting at least 12 months after your last surgery before pursuing revision, as discussed in our guide on why you should wait before seeking revision. However, if your breathing difficulties are severe, an earlier consultation may be appropriate.
Take the First Step
Nasal valve collapse is treatable, and you do not have to live with breathing difficulties. Our team specializes in functional revision rhinoplasty and has helped thousands of patients breathe freely again.
If you suspect you have nasal valve collapse, schedule a consultation with our team. We will perform a thorough nasal examination, including endoscopic evaluation and possibly rhinomanometry (a test that measures nasal airflow), to determine the best treatment plan for your specific anatomy.
