A nasal bridle is a thin loop of silicone tubing that hooks around a bone deep inside your nose to anchor a feeding tube in place. Unlike adhesive tape stuck to the outside of your skin, a bridle creates an internal anchor point that resists pulling, making it far more effective at preventing accidental tube removal. It’s used most often in hospital patients who are confused, agitated, or otherwise at risk of yanking out their feeding tube.
The Anatomy Behind It
The key structure is the vomer bone, a flat bone that forms the back part of your nasal septum (the wall dividing your two nostrils). The vomer sits deep inside the nose, well behind the nostrils, and the bridle loops around it like a piece of string draped over a fence post. Because the bone is rigid and firmly anchored in the skull, it provides a stable attachment point. If someone tugs on the feeding tube, the force transfers to the bridle loop, which catches on the vomer rather than simply peeling off like tape would.
How Placement Works
The bridle itself is made of flexible silicone tubing with a small plastic clip. Placing it requires a pair of special insertion probes, each tipped with a small magnet. One probe goes into the left nostril, the other into the right. The clinician advances both probes along the floor of each nasal passage until they reach the back of the nasal cavity, behind the vomer bone. At that point, the two magnets snap together through the thin tissue, connecting the probes behind the septum.
With the magnets linked, the clinician pulls one probe back out, drawing the silicone tubing with it. This threads the tubing in one nostril, around the back of the vomer, and out the other nostril, forming a U-shaped loop. The feeding tube is then secured to the bridle with the plastic clip so both sit together in one nostril. Some clinicians place the bridle before inserting the feeding tube itself, since this leaves more room in the nasal passage for the tube to pass through.
Why It Works Better Than Tape
Standard adhesive tape relies entirely on skin adhesion. Sweat, oily skin, nasal secretions, and simple friction can loosen it within hours. Patients who are restless, confused, or recovering from brain injuries frequently pull their tubes out, sometimes multiple times in a single hospital stay.
A nasal bridle essentially eliminates this problem. In one study of pediatric patients after airway surgery, the unbridled group experienced 9.4 tube pullouts per 100 patient-days. The bridled group had zero pullouts across the entire study period. That kind of reduction matters because every dislodged tube means reinsertion (uncomfortable for the patient), a confirmatory X-ray (radiation exposure), and lost feeding time. One cost analysis estimated that using nasal bridles saved roughly $4,038 over three months per patient compared to adhesive tape, factoring in fewer reinsertions, less staff time, reduced X-ray exposure, and better caloric intake.
What It Feels Like
The insertion process takes only a few minutes. Patients typically feel pressure and mild discomfort as the probes pass through the nasal passages, similar to having a feeding tube placed. Once the bridle is seated, most people don’t notice it during normal activity. The silicone tubing is soft and thin enough that it doesn’t obstruct breathing. The bridle can stay in place for the entire duration a feeding tube is needed, whether that’s days or weeks, without requiring replacement on a fixed schedule.
Daily Care
The bridle site needs daily inspection and cleaning. This is straightforward: a damp cloth or gauze with water is used to wipe around the nostrils, clearing away nasal secretions that can build up and harden around the tubing. The area should be checked each day for redness, swelling, or signs of irritation. The feeding tube itself should be repositioned weekly to prevent pressure from sitting in exactly the same spot for too long.
Possible Complications
Nasal bridles are generally safe, but they aren’t risk-free. An analysis of adverse events reported to the FDA found 24 unique complications. The most common, accounting for about 63% of reports, involved a piece of the bridle being retained inside the nose as a foreign body, typically a fragment left behind during removal. About 17% of reports involved lacerations to the nasal septum during placement or removal. Another 12.5% were septal tears caused by patients forcefully ripping the tube and bridle out, which is essentially the bridle doing its job (resisting removal) but resulting in tissue damage when someone pulls hard enough to overcome that resistance. Skin irritation and pressure-related tissue damage were rare, each appearing in only one report.
These numbers come from a voluntary reporting database, so they represent notable events rather than a true complication rate across all uses. Still, they highlight why proper placement technique and careful removal matter.
How Removal Works
Removing a nasal bridle is simpler than placing one. The clinician cuts one side of the silicone tubing between the nose and the securing clip, then gently pulls both the bridle and the feeding tube out together through the same nostril. The loop slides off the vomer and out without requiring any special instruments. The key is cutting the tubing first so it can slide freely rather than catching on the bone.
Who Gets a Nasal Bridle
Bridles are most commonly used for patients in intensive care units, those recovering from neurological injuries, people with dementia or delirium, and anyone with a pattern of repeatedly pulling out feeding tubes. They’re also used after certain surgeries where maintaining tube feeding is critical and reinsertion would be difficult or risky. Patients with nasal fractures, significant septal deviation, or recent facial surgery may not be good candidates, since the anatomy needs to be intact enough for the probes to pass safely around the vomer.
