How ClearPath May Improve Endoscopic Access and Line of Sight for Surgeons

When you hear a surgeon talk about “better visualization” in nasal surgery, it’s easy to picture a higher‑definition camera. In reality, endoscopic visualization depends on something more basic: having enough open, straight space inside the nose to see and work safely. This article focuses on surgical access and line of sight—not camera resolution.

That matters because a deviated septum can narrow the nasal corridor and make it harder to move an endoscope and instruments where they need to go. One approach intended to help create that working space is ClearPath—use of a nasal balloon catheter in balloon-assisted septoplasty—to support septal alignment and access in select patients.

What “better visualization” means in nasal and sinus surgery

Visualization isn’t just the camera—it’s the space to work

Many ENT procedures are performed using an endoscope (a small camera). The endoscope provides the view—but the surgeon still needs room to maneuver. If the corridor is tight, the endoscope may not easily reach the target area, and instruments may have limited angles to do precise work.

A helpful analogy: think of the endoscope as a flashlight and the nasal corridor as a hallway. A brighter flashlight helps—but if the hallway is kinked or narrowed, you still can’t comfortably move through it or position your tools.

In other words, endoscopic visualization isn’t only about image quality. It’s also about:

- A clear line of sight to the anatomy

- Enough space to pass the endoscope safely

- Enough working room to use instruments effectively

Why a deviated septum can limit the surgeon’s view

A deviated septum means the wall separating the two sides of the nose is shifted off-center. Depending on where and how severe the deviation is, it can create a “bottleneck” that:

- Narrows the corridor the endoscope travels through

- Forces more difficult angles to see around curves

- Increases contact between instruments and delicate tissue (which can contribute to irritation and bleeding)

A concrete example: if the septum bows into one nasal passage near the front, the surgeon may need to advance the endoscope close to the lateral wall to pass—reducing working angles and making instrument exchanges feel like navigating a tight turn. Even modest straightening can make common tasks (such as advancing the scope, suctioning, or positioning instruments) more direct. If you want a simple overview of how deviations can affect breathing and nasal function, see: deviated septum symptoms and causes (https://www.clearpathnasal.com/blog/deviated-septum-explained-symptoms-causes-and-modern-treatment-options).

Where CT imaging fits in (before and after surgery)

A CT scan for septoplasty planning can help map nasal and sinus anatomy in detail. Surgeons often use CT images to understand:

- Where the septum is deviated (and by how much)

- Nearby landmarks and naturally narrow areas

- How the septum relates to sinus drainage pathways

CT scans are also used in research settings to measure alignment changes after septal procedures. (Dillard et al., 2026)

For a patient-friendly explanation of how imaging is used, see: how CT scans help diagnose nasal blockages (https://www.clearpathnasal.com/blog/how-we-use-ct-scans-to-diagnose-nasal-blockages).

Bottom line: in endoscopic surgery, “seeing better” often starts with a straighter, more open pathway—not a different camera.

What ClearPath is (and what it is not)

ClearPath Nasal Balloon Catheter in plain language

ClearPath in this context refers to use of the ClearPath Nasal Balloon Catheter—a device intended to support balloon-assisted septoplasty. In simple terms, the goal is to help improve septal alignment to open the nasal corridor and support surgical access.

This is often described as a minimally invasive approach to septal correction because it focuses on alignment with an intent to limit disruption of surrounding structures. For many patients, that “less disruption” concept matters because swelling, bleeding, and healing time can be influenced by how much tissue is manipulated. Individual experiences vary.

For a step-by-step overview, see: what balloon-assisted septoplasty is (https://www.clearpathnasal.com/blog/what-is-balloon-assisted-septoplasty).

What ClearPath is not: surgical navigation or AR registration

ClearPath is a device that may help create a more workable nasal corridor. It is not a navigation or augmented reality system that overlays guidance onto a surgical video feed. Some operating rooms use technologies that enhance intraoperative viewing or guidance, but ClearPath’s role is different: it focuses on space creation, which can make endoscopic work more direct. (Hadjipanayis et al., 2022)

A simple way to separate these ideas:

- Navigation/AR tools add information to what you see.

- Corridor-improvement tools make it easier to see and reach what’s already there.

Name confusion to avoid

Because “ClearPath/Clearpath” is used by different healthcare brands, this article refers specifically to the ClearPath Nasal Balloon Catheter used for septal correction—not unrelated products or services with similar names in other areas of medicine.

Takeaway: ClearPath is described as a device used in balloon-assisted septoplasty for select patients and anatomy patterns; it is not a visualization overlay or navigation system.

How ClearPath may improve a surgeon’s endoscopic “view” during procedures

Creating a straighter, more open corridor

When septal alignment improves, the nasal passage may become more symmetric and less obstructed. That can help by:

- Allowing the endoscope to pass more smoothly

- Reducing the need to work around a curve or tight spot

- Improving the consistency of the line of sight to key anatomy

In practical terms, ClearPath use in balloon-assisted septoplasty is intended to support better endoscopic visualization by improving the pathway the surgeon uses to look and operate.

Helping surgeons reach target areas more directly

A more open corridor may also support sinus surgery access, because surgeons often need to reach deeper structures through the nasal passage. When the path is narrow or sharply deviated, reaching specific targets can be more challenging.

For more background on the corridor concept, see: balloon septoplasty for sinus and skull base access (https://www.clearpathnasal.com/blog/balloon-septoplasty-for-sinus-skull-base-access-new-frontiers).

Potential workflow considerations in the OR

Every patient’s anatomy is different, and no technique can guarantee a specific operative experience. Still, when a septal deviation is a primary obstacle, improving the corridor may mean:

- Less time navigating around the deviation

- More direct instrument paths

- More ability to focus on the surgical goal rather than the “traffic jam” getting there

Clinicians often summarize the goal this way: if we can make the route in cleaner and straighter, the rest of the work may become more controlled. These are potential workflow advantages aligned with the broader aim of supporting access and precision in endoscopic surgery.

In short, straightening the corridor may make it easier for the surgeon to see and reach what matters—without promising the same result for everyone.

What published findings suggest about alignment and outcomes

Study size and what was measured

A retrospective analysis reported outcomes for 107 consecutive cases of CNB-assisted septoplasty. In that group:

- 23 patients had both pre- and post-operative CT scans

- 43 patients completed SNOT-22 symptom surveys

(Dillard et al., 2026) Retrospective data can help describe real-world experiences and measurable changes, but results depend on patient selection, anatomy, and follow-up.

Objective alignment improvements seen on CT

Using CT-based measurements, the study reported improved septal symmetry:

- 22% mean symmetry improvement at the nasolacrimal duct (NLD) level

- 45% mean symmetry improvement at the point of maximal deviation (PMD)

(Dillard et al., 2026) These measurements matter because they offer an objective way to evaluate alignment changes—not just symptom trends.

Safety findings

In that cohort, the authors reported no major intraoperative or postoperative complications, including septal perforation, hematoma, mucosal injury, infection, synechia, or conversion to traditional septoplasty. (Dillard et al., 2026) Individual risk varies based on anatomy, medical history, and whether additional procedures are performed.

Patient-reported symptom improvement

Among patients who completed symptom surveys, SNOT-22 scores improved from 58.7 to 44.8 at one month—about a 23.8% reduction. Areas with the largest reported gains included congestion, headache/facial pressure, and sleep quality. (Dillard et al., 2026)

Who may see the biggest proportional correction

In the CT subgroup, patients with more severe deviation (>10 mm) showed the largest proportional improvement. The authors also reported that 78% (18/23) achieved at least 30% improvement in alignment. (Dillard et al., 2026) This does not mean more severe always equals better results; rather, substantial deviations may offer more room—literally—for measurable correction.

Overall, one retrospective study observed meaningful alignment changes on CT and symptom improvements in many participants, with no major complications reported in that cohort.

How imaging supports visualization (and a quick clarification about “Clearpath” imaging platforms)

Why surgeons rely on imaging for planning

Even with a skilled endoscopic exam, imaging adds important details for surgical planning. CT can help a surgeon anticipate:

- The tightest segments of the nasal corridor

- Key anatomical landmarks

- Asymmetry that may affect access and approach

In practice, when CT shows a tight corridor at a specific level, the surgeon can plan the approach (and any septal correction) to create the most meaningful working space where it’s needed most.

Clarification: “Clearpath” medical image-sharing platforms are a different service

Separately from the ClearPath Nasal Balloon Catheter device, there are healthcare services named “Clearpath” that focus on sharing and delivering CT/MRI/X-ray images. Those platforms are not the septoplasty device discussed here. In general, faster access to imaging can help clinicians plan and coordinate care more smoothly, though these platforms are not AR/registration navigation systems. (Hadjipanayis et al., 2022; Clearpath, n.d.; ITNOnline, 2023; RBMA, n.d.) Important name note: Ahmed ClearPath is a glaucoma drainage implant and is unrelated to either the septoplasty device or the imaging platform. (Glaucoma Today, 2019)

Good imaging supports planning, which supports access—so surgeons are less likely to be surprised by hidden narrow points.

What this means for patients considering septal correction

The practical takeaway: better access can support precision

If a deviated septum is limiting the nasal corridor, improving septal alignment may help create a more open pathway for the endoscope and surgical instruments. ClearPath use in balloon-assisted septoplasty is designed with that corridor goal in mind—supporting the surgeon’s ability to see and work more directly.

Setting expectations

- Anatomy varies widely from person to person

- Some deviations are more complex than others

- Some patients may need additional procedures based on symptoms and imaging

- CT imaging is used selectively for planning, depending on clinical needs

Questions to ask your ENT surgeon

- How does my deviation affect access and visibility during endoscopic work?

- Will I need sinus surgery too, or is septal correction the main issue?

- Do you use CT to plan and confirm alignment?

If you’re exploring alternatives to traditional septoplasty, ask your local ENT whether ClearPath (balloon-assisted septoplasty) is an option for your specific deviation pattern and goals. For quick answers, see ClearPath FAQs (https://www.clearpathnasal.com/faqs). If you’re a clinician seeking technical details, visit: Learn more for physicians (https://www.clearpathnasal.com/for-physicians).

Talk with your ENT about whether septal alignment—potentially with a device-assisted approach—fits your anatomy and treatment plan.

FAQs

Does ClearPath replace traditional septoplasty?

ClearPath is a device-based approach used in balloon-assisted septoplasty and may be an option for certain patients and deviation patterns. Whether it’s the best approach depends on anatomy, severity, and whether other nasal concerns need to be addressed at the same time.

Will I need a CT scan before or after?

Not everyone needs CT imaging for septal evaluation. A CT scan for septoplasty planning is more common when symptoms suggest sinus involvement, when anatomy is complex, or when objective mapping helps guide care. Post‑operative CT scans are more common in research and specific follow‑up scenarios than in routine care. (Dillard et al., 2026)

Is ClearPath the same as the Clearpath medical image‑sharing platform?

No. The ClearPath Nasal Balloon Catheter is a septal correction device. “Clearpath” imaging platforms refer to services for delivering and sharing medical images and records. (Clearpath, n.d.; ITNOnline, 2023; RBMA, n.d.)
