Why Dr. Dillard Invented the ClearPath System

If you live with nasal obstruction from a deviated septum, you may have heard that septoplasty is effective—but it can also feel like a big step. Many people delay care because they worry about invasiveness, packing, and downtime. If you’re just getting oriented, a useful primer is: What is balloon-assisted septoplasty? https://www.clearpathnasal.com/blog/what-is-balloon-assisted-septoplasty

The ClearPath Nasal Balloon System is a device that enables balloon-assisted septal correction (sometimes called “balloon septoplasty”). It was developed to give appropriately selected patients a more tissue-preserving option—one that aims to reduce cutting, broad tissue manipulation, the need for packing, and recovery burden when those steps are not necessary for the anatomy. Individual results vary, and ClearPath is not a replacement for every septoplasty.

The problem Dr. Dillard kept seeing with “traditional” septal surgery

Traditional septoplasty is a proven treatment and often the best choice—especially for complex deviations. But in everyday practice, not every patient needs the same level of invasiveness to get meaningful breathing improvement. The real challenge is matching the method to the anatomy.

Why septoplasty can feel like a big step for patients

- Incisions and internal healing

- Swelling, bruising, and tenderness

- Nasal packing (and discomfort when it’s removed)

- Time away from work, exercise restrictions, and overall downtime

- A recovery that feels longer than expected

Even when outcomes are good, these concerns can lead people to postpone care—sometimes for years—while living with congestion, mouth breathing, sleep disruption, and reduced quality of life.

Why septoplasty can feel like a big step

The core challenge: correcting structure without unnecessary trauma

Many conventional techniques use cutting and broader tissue manipulation to access and reshape the septum. That can be necessary for severe or complex deviations. But when a deviation can be mobilized and guided back into better alignment, a more targeted, tissue-preserving approach may be possible. ClearPath was created to offer that option—specifically to help reduce reliance on cutting, packing, and prolonged recovery in selected cases.

The goal is to match the least disruptive method to the anatomy that needs help.

Match the method to the anatomy

What inspired ClearPath: a simpler, tissue-preserving approach

The intent behind ClearPath was not to replace every septoplasty. It was to modernize how some deviations are corrected by using a more targeted method—where less disruption can still be enough to improve airflow.

Built from years of clinical experience and research

ClearPath’s design reflects years of clinical experience focused on simplifying septal correction for suitable anatomy. From a patient perspective, “simplifying” often means:

- Fewer steps that involve cutting or removing tissue when it isn’t required

- A correction method focused on the true point(s) of blockage

- A care plan that balances comfort and recovery expectations alongside results

A design goal: preserve more tissue while still improving airflow

Instead of primarily removing or widely reshaping tissue, ClearPath aims to help reposition selected nasal structures to create more breathing room—when the anatomy is amenable. Think “guided realignment” rather than “carving away” tissue.

When the anatomy allows, targeted repositioning can create space while preserving more normal tissue.

How the ClearPath System works (simple step-by-step)

ClearPath is a device-enabled, balloon-assisted approach that uses controlled dilation to help reshape and reposition targeted internal nasal anatomy. For a deeper walkthrough, see: How the ClearPath nasal balloon works (step-by-step) https://www.clearpathnasal.com/blog/how-the-clearpath-nasal-balloon-works-a-step-by-step-guide

The guided balloon concept: controlled force, targeted correction

ClearPath uses a balloon catheter to apply measured, controlled dilation—intended to mobilize and reposition specific areas rather than relying on broad manipulation. In descriptions of the technique, this “force-directed” approach is presented as aiming to reduce or avoid flap elevation, packing, and prolonged anesthesia in selected situations. These are intended goals and not guaranteed outcomes.

The reusable guide spatula: why guidance matters

A shaped, reusable guide helps stabilize and direct the dilation, improving precision so the force is applied where it’s intended. Better guidance can enable targeted correction without broader tissue disruption—again, when the deviation pattern is suitable.

What areas it’s designed to address

ClearPath is designed to address regions such as the lower septum and the inferior turbinate area, aiming to increase intranasal space that supports airflow. The intent is to create more room to breathe while preserving tissue when feasible for the individual anatomy.

The method is deliberate and targeted: guide, dilate, and reposition the structures that are actually blocking airflow.

How ClearPath works: guide, dilate, reposition

Why balloon-assisted can be different from conventional septoplasty

Less cutting and less tissue disruption (for the right anatomy)

ClearPath is described as a less-traumatic alternative for appropriate cases, with the aim of reducing cutting and broader disruption. In some patients, this may also lessen the need for packing and shorten procedure time. These are intended advantages in selected situations and are not guaranteed.

Precision: moving specific structures instead of broad reshaping

The emphasis is on targeted repositioning—applying controlled dilation to the specific structure(s) that narrow airflow—rather than wide reshaping. For patients, precision often translates to fewer “moving parts” and less manipulation of areas that aren’t the primary problem.

Recovery: what patients usually care about most

When people ask about “minimally invasive,” they are often asking about recovery. Possible advantages, when anatomy and technique allow, can include:

- Less early bleeding

- Less or no packing (when clinically appropriate)

- Less intense early congestion or discomfort

- Shorter downtime before returning to work and light activity

Expectations still need to be realistic. Recovery varies based on anatomy, procedure details, and individual healing—no approach can promise a specific timeline. If you’re comparing timelines, this overview can help: Septoplasty recovery time: what to expect https://www.clearpathnasal.com/blog/what-is-the-recovery-time-for-septoplasty

Think “more targeted access, less collateral disruption” when the anatomy is a fit.

Who ClearPath may (and may not) be best for

Best-fit candidates: selected soft-tissue or cartilaginous obstruction

Some deviations are more “movable” and respond to controlled repositioning. ClearPath materials emphasize selected soft-tissue or cartilaginous obstruction patterns as a better fit. A simple rule of thumb: if the limiting anatomy can be mobilized and guided, balloon-assisted repositioning may be worth discussing.

When traditional surgery may still be needed

More rigid, complex, or severe deviations—such as hard bony spurs or pronounced deformities—often require traditional techniques. A proper evaluation typically includes a detailed nasal exam, a review of symptoms (including sleep), and sometimes imaging such as a CT scan when indicated.

The right tool depends on the problem: some septums need rebuilding; others benefit from precise repositioning.

Who it may fit: movable vs rigid anatomy

What the evidence says so far (safety and outcomes)

Safety results reported in a 107-case retrospective series

In a retrospective series of 107 consecutive ClearPath procedures, no major complications of the types listed (such as septal perforation, hematoma, synechiae, or conversion to flap-based surgery) were reported. These findings come from the developer’s series and should be validated in larger, independent studies and in comparative trials.

Imaging changes: what CT scans showed in a small subgroup

Among a subgroup with both pre- and post-operative CT scans (n=23), mean radiographic septal alignment improved by approximately 45% at the point of maximal deviation and 22% at the nasolacrimal duct (both statistically significant in that analysis). These are imaging-based measures of alignment—not direct measures of symptoms or airflow.

Quality of life: short-term symptom change (SNOT-22)

In patients with one-month follow-up SNOT-22 data (n=43), average scores improved from about 58.7 to 44.8 (roughly a 24% reduction). This reflects short-term, selected-cohort symptom change and is not a head-to-head comparison with traditional septoplasty or a long-term result.

A quick note on what this data can—and can’t—prove

The early evidence is encouraging but retrospective and developer-authored. Larger, prospective, and independent studies—ideally with direct comparisons and longer follow-up—are needed to better define which patients benefit most and how outcomes stack up across approaches.

Early results suggest the concept is promising for selected patients, but broader, independent research will clarify who benefits most and how durable the results are.

Evidence and FDA clearance overview

FDA clearance and what it means (in simple terms)

ClearPath’s FDA record: Dillard Nasal Balloon Catheter

FDA records identify the device as the Dillard Nasal Balloon Catheter, with a 510(k) clearance decision recorded on January 3, 2020 (K181546). FDA 510(k) summaries describe the device’s intended use and the basis for clearance; they do not rank devices by clinical superiority.

What 510(k) clearance generally indicates for patients

In general, 510(k) clearance allows a device to be marketed for its indicated use based on safety and substantial equivalence to a legally marketed predicate. It does not mean the device is the only or automatically the best option for every patient; it means it met regulatory standards for its indication.

FDA clearance supports that the device can be marketed for its indicated use; your ENT helps decide if it is appropriate for your anatomy.

The bottom line: the “why” behind ClearPath

Dr. Dillard’s goal: modernize septal correction with less disruption

ClearPath exists because many patients need real breathing improvement but hesitate when the default path feels more invasive than their anatomy may require. It was designed as a guided, device-based approach to improve precision and reduce tissue disruption in appropriate candidates—while aiming for what patients care most about: easier, more reliable nasal breathing.

Your next step if you think you might be a candidate

A good next step is a focused nasal exam and a conversation about your symptoms and goals. If needed, imaging can clarify the cause of obstruction and whether balloon-assisted septal correction is a fit for you. You may also find these helpful:
