Why “Vertical Ridges” in the Nose Cause Blockages

If you’ve ever been told you have a “vertical ridge” inside your nose, it can be confusing—especially if the ENT describes it as “small.” Yet your breathing may feel anything but small: like air hits a wall, or that one side never opens, or as if you’re always slightly congested even when you’re not sick.

The reason is usually location. Many of these ridges sit at (or very near) the narrowest part of the nasal airway. In that pinch-point, a subtle bump can create a surprisingly large airflow bottleneck—similar to how a small lane closure can cause major traffic in the tightest part of a highway merge. Below, we’ll cover what this “ridge” usually is, how ENTs confirm it, and what treatments—including modern septoplasty options like balloon-assisted approaches using the ClearPath Nasal Balloon device—may help.

Quick Answer: What Is a “Vertical Ridge” Inside the Nose?

In patient-friendly terms, a “vertical ridge” often refers to a localized bend or bony/cartilaginous protrusion on the nasal septum (the wall that separates the left and right nostrils). In medical language, you may hear it called a vertical septal ridge or a septal spur.

Why it matters: these ridges are commonly close to (or within) the internal nasal valve, which is the narrowest part of the nasal airway. Because that area is already tight, a small ridge there can create an outsized sensation of blockage and increased resistance (Alghamdi et al., 2022; Patel et al., 2018). This is a key reason vertical ridges in the nose can cause blockages that feel persistent or severe.

What patients often mean when they say “it feels blocked”

- People don’t always describe this as “pain” or “pressure.” More often it’s practical: “I can inhale, but not comfortably,” or “Air only moves on one side,” especially during workouts, at night, or when you’re trying to sleep with your mouth closed.

Vertical ridge vs. general deviated septum

- A “deviated septum” can describe many different shapes and locations. A broader, deeper deviation may cause symptoms—but a high, front-of-the-nose ridge near the internal nasal valve is especially likely to cause the “I can’t get air through” feeling because it affects the airway’s natural pinch point (Alghamdi et al., 2022; Patel et al., 2018).

Takeaway: A small ridge at the valve can feel like a big blockage.

The Internal Nasal Valve: Why This One Small Area Causes Big Symptoms

Think of the internal nasal valve as the bottleneck of nasal breathing. It’s the narrow zone where airflow is most restricted even in a perfectly normal nose.

The key concept is that small reductions in the valve’s open space can cause a large increase in airflow resistance, meaning you have to work harder to move the same amount of air (Patel et al., 2018; Alghamdi et al., 2022). This is one of the main reasons vertical ridges in the nose can cause blockages that feel worse than you’d expect.

A helpful analogy: the “hourglass neck” of nasal breathing

- Imagine your nasal airway as an hourglass. You can pour plenty of sand into the top, but the narrow “neck” controls the flow. The internal nasal valve is that neck. If a ridge takes up even a little space there, the whole system feels restricted—regardless of how open the rest of the nose is.

Why airflow feels “stuck” (resistance + turbulence)

- A ridge at or near the valve can:

- Physically narrow the available space

- Increase resistance so the nose feels “tight”

- Create turbulence (disrupted airflow) that can mimic the sensation of congestion even when there isn’t much mucus present (Alghamdi et al., 2022)

That turbulence point matters. It helps explain why someone can feel congested, try allergy treatments, and still feel like airflow is messy or incomplete—because the problem isn’t just swelling. It’s also the geometry of airflow through a narrowed, irregular channel.

Takeaway: Small changes at the valve can have big breathing effects.

Mladina Classification: Where “Vertical Ridges” Fit In

ENT specialists sometimes use classification systems to describe septal shapes more precisely. One commonly cited system is the Mladina classification (Mladina, 1987; Teixeira et al., 2016).

This matters because “deviated septum” is a broad label, while a classification can help clarify where the deviation is and why it’s likely (or unlikely) to cause valve-region obstruction.

Type I vs. Type II (vertical ridge in the valve region)

- In this system, vertical ridge patterns near the front of the nose are often described as:

- Mladina Type I: a vertical ridge that does not reach the internal nasal valve

- Mladina Type II: a vertical ridge that touches the internal nasal valve (more likely to obstruct)

Because Type II involves the valve area itself, it’s more likely to be associated with true airflow limitation and persistent symptoms (Teixeira et al., 2016). Put simply, vertical ridges in the nose most dramatically cause blockages when they interfere with the valve region.

If you want a deeper dive, this ClearPath resource explains how deviation patterns can relate to results: septoplasty outcomes by Mladina deviation type.

Takeaway: Valve-involving ridges (Type II) tend to matter most.

Symptoms People Commonly Notice When a Vertical Ridge Is the Problem

A vertical septal ridge or septal spur can show up in everyday life in recognizable ways, including:

- One side always feels blocked, especially during exercise or at night

- A congestion sensation that doesn’t match typical allergy patterns

- Worse breathing when lying down, or waking with a dry mouth from mouth-breathing

- Temporary improvement with decongestant-type approaches, but symptoms return quickly

A concrete example: “I’m fine at rest, but I can’t breathe when I run”

- It’s common for structural narrowing at the valve to become more obvious when you need more airflow—like during a jog, a long walk, or climbing stairs. At rest, you may compensate without thinking. Under demand, that narrow spot becomes the limiting factor.

How to tell swelling vs. structure (a helpful rule of thumb)

- A simple rule of thumb: if you feel “narrow” even when you’re not sick—and if symptom relief from sprays is partial or short-lived—there may be a structural component (like a ridge) in addition to any inflammation.

- This article may help you compare patterns: deviated septum vs allergies—how to tell the difference.

Only an in-person exam can confirm the real cause, but noticing these patterns can help you ask better questions.

Takeaway: If sprays only help a little, structure may be part of the story.

What Causes Vertical Septal Ridges or Spurs?

Common causes include:

- Natural growth and anatomy differences (many septal shapes develop as the face grows)

- Prior nasal trauma, including injuries that happened years earlier

- Developmental changes where cartilage and bone grow unevenly over time

Why they’re often “high and forward”

- Many symptomatic ridges are high and toward the front of the nose—right where airflow is already naturally tight (the valve region). That positioning is one reason vertical ridges in the nose can cause blockages that seem disproportionate to their size (Alghamdi et al., 2022; Teixeira et al., 2016).

Note: A vertical ridge is not the only possible cause of nasal obstruction. Turbinate enlargement, mucosal inflammation (from allergies/irritants), nasal valve collapse, polyps, or other anatomical variations can also contribute—sometimes together with a ridge.

Takeaway: Where the ridge sits matters as much as its size.

How ENTs Confirm a Vertical Ridge (Not Just “Guessing”)

ENTs typically confirm a ridge using a stepwise evaluation:

- In-office nasal exam to look at the front of the septum and surrounding tissue

- A more complete endoscopic nasal evaluation (a detailed look deeper inside the nose)

- Imaging when needed—particularly when symptoms are significant, anatomy is complex, or surgical planning is being considered

Objective testing: when “it feels blocked” becomes measurable

- Depending on the clinic and the clinical question, ENTs may reference objective tools discussed in the literature—such as endoscopy, CT/CBCT imaging, or airflow testing approaches (e.g., acoustic rhinometry, rhinomanometry, and computational airflow modeling described in reviews) to better characterize narrowing and airflow patterns (Alghamdi et al., 2022). Not everyone needs these tests, but they can be useful when symptoms and exam findings don’t fully match.

Why imaging can matter for focal valve-region ridges

- Focal, anterior ridges can look “small,” but they may sit at the exact point where your airway is tightest. Imaging can help show where narrowing is most significant and whether other structures (like turbinates) also contribute.

Takeaway: A careful exam links what you feel to what’s seen.

Treatment Options: What Actually Helps (and What Usually Doesn’t)

Treatment usually follows a stepwise plan based on symptom burden, exam findings, and how much swelling vs. structure is involved.

Conservative treatment (helps swelling, not the ridge itself)

- These options can reduce inflammation around a ridge:

- Intranasal steroid sprays (for mucosal inflammation). These reduce swelling but do not change the septum’s shape or fix structural issues.

- Saline irrigation (to reduce irritants and crusting)

- Short-term decongestant use in select situations (follow label instructions and clinician guidance; overuse can lead to rebound congestion)

These approaches may improve the tissue swelling around the ridge, but they typically do not remove the underlying structural narrowing (Alghamdi et al., 2022). If the ridge is the primary issue, you may still feel restricted—often described as, “I’m less puffy, but the airflow is still tight.”

When surgery becomes the most effective fix

- If symptoms persist and exam findings suggest the ridge is the main cause of obstruction, septoplasty (often using tailored or endoscopic approaches based on the ridge’s location) is the primary method used to improve airflow (Alghamdi et al., 2022; Teixeira et al., 2016).

Takeaway: Medicines calm swelling; surgery addresses structure.

Modern Septoplasty Approaches for Vertical Ridges (Including Minimally Invasive Options)

The best approach depends on where the ridge is and whether it affects the internal nasal valve.

Traditional septoplasty vs. targeted valve-region repair

- A focal valve-region ridge may require a more targeted plan than a broad deviation deeper in the nose. This is one reason detailed evaluation and clear surgical goals matter (Patel et al., 2018; Alghamdi et al., 2022). In plain language, a surgeon may focus less on “straightening everything” and more on improving the specific pinch-point that’s driving symptoms.

- For a patient-friendly overview of approach differences, see: endoscopic septoplasty vs open surgery.

Balloon-assisted endoscopic septoplasty (ClearPath Nasal Balloon context)

- Some surgeons may use balloon-assisted techniques to help reposition septal areas with less tissue disruption, depending on anatomy and goals. The ClearPath Nasal Balloon is a medical device designed to support balloon-assisted endoscopic septoplasty in appropriate candidates—typically discussed alongside more traditional approaches. For basics, see: what balloon septoplasty is (and who it may help).

- Availability and evidence note: The ClearPath Nasal Balloon is one of several devices explored for balloon-assisted septoplasty and may be offered in select centers. While early results are promising, larger randomized trials and long-term outcomes are still limited.

Evidence snapshot (authors’ report)

- A retrospective series reported outcomes in 107 cases using this technique and device (Dillard et al., Rhinology Online, 2026; forthcoming/in press). Key findings reported by the authors included:

- Safety in that series: no major intra- or post-operative complications were observed (no septal perforation/hematoma/synechia reported).

- Imaging changes (subset of 23 with comparisons): septal alignment improved by a mean of 45% at maximal deviation and 22% at the nasolacrimal duct (p=0.005).

- Symptom scores: average SNOT-22 decreased by 24%, with notable improvement in congestion, facial pressure/headache, and sleep quality at about one month.

- These findings are encouraging, but they don’t guarantee individual results—your outcome depends on your anatomy, the exact ridge location (including valve involvement), and whether other contributors to nasal obstruction are present.

Takeaway: The best plan targets your specific pinch point.

What to Ask Your ENT If You’ve Been Told You Have a “Vertical Ridge”

Questions that lead to clarity

- Is the ridge in the internal nasal valve area?

- Does it match a Mladina Type I or Type II pattern?

- Is there turbinate enlargement, valve collapse, or inflammation contributing too?

- Would medical therapy meaningfully help, or is the obstruction mostly structural?

- For my ridge location, is a traditional approach best—or would a tailored/endoscopic plan or a balloon-assisted approach using the ClearPath Nasal Balloon device be reasonable to discuss?

Takeaway: Clear questions help match treatment to your anatomy.

When to Seek Care (and When to Seek Care Urgently)

Make an appointment if

- Nasal blockage lasts more than 8–12 weeks

- Sleep, exercise, or daily breathing is consistently impaired

- Symptoms are one-sided and persistent

Urgent evaluation if

- Recurrent heavy nosebleeds

- Severe facial pain with fever

- New blockage after trauma

Takeaway: Persistent or one-sided blockage deserves evaluation.

Summary: Why a Small “Ridge” Can Feel Like a Big Blockage

A “vertical ridge” is often a localized septal shape change (a vertical septal ridge or septal spur) that sits near the internal nasal valve, the nose’s natural airflow bottleneck. That’s why vertical ridges in the nose can cause blockages that feel intense, especially with activity or during sleep. ENTs confirm the cause with a careful nasal evaluation and sometimes imaging. If sprays don’t provide lasting relief and the obstruction is structural, septoplasty—including modern, targeted options and, in select cases, balloon-assisted approaches using the ClearPath Nasal Balloon—may help restore airflow (Mladina, 1987; Teixeira et al., 2016; Alghamdi et al., 2022; Patel et al., 2018).

CTA: If you’ve been told you have a vertical ridge (or suspect one), schedule a visit with your local ENT and ask whether your ridge involves the internal nasal valve—and whether traditional septoplasty, a tailored endoscopic approach, or a balloon-assisted option such as ClearPath could be appropriate to discuss.

Takeaway: A focused fix can reopen the bottleneck.
