Nasal dilators are simple, non-medicinal devices designed to mechanically widen the narrowest parts of the nasal passages to improve airflow. They function by physically opening the nasal valve area, which accounts for a significant portion of total airway resistance. Using a dilator can lead to easier breathing, reducing common issues like snoring and congestion caused by colds, allergies, or minor structural variations. This mechanical assistance stabilizes the soft tissues of the nose, preventing them from collapsing inward during inhalation, especially at night.
Understanding the Types of Nasal Dilators
The devices used to widen the nasal passages fall into two main categories, distinguished by where they are applied to the nose. Each type employs a different mechanism to reduce airflow resistance. The choice often depends on the user’s preference for comfort and the specific location of their breathing restriction.
External nasal dilators, commonly known as nasal strips, are adhesive bands placed across the bridge of the nose. These strips contain flexible, spring-like bands that gently pull the sides of the nose outward and upward, lifting the soft tissue to open the nasal passages from the exterior. Their effectiveness comes from stabilizing the lateral nasal vestibule, preventing the natural collapse that can occur during deep breathing.
Internal nasal dilators are small, flexible devices, often cone-shaped or cylindrical, made from soft medical-grade materials like silicone. These are inserted directly into the nostrils, where they exert gentle, outward pressure against the walls of the nasal passages. By physically propping open the nasal valve from the inside, they increase the cross-sectional area available for air to flow. This internal placement directly targets the narrowest part of the airway, providing consistent support.
Step-by-Step Guide for Insertion and Placement
Applying an external nasal strip requires careful skin preparation to ensure maximum adhesion and effectiveness. First, the nose and surrounding area must be washed thoroughly with a mild soap to remove oils, makeup, or dirt, and then dried completely. Oils and moisture compromise the adhesive, causing the strip to peel off prematurely.
Next, peel the protective liner off the strip and center it horizontally across the bridge of the nose. Correct placement is just above the flared part of the nostrils, where the soft tissue begins to curve outward. Once centered, press the strip down firmly along its entire length, smoothing outward from the center to ensure the adhesive fully bonds with the skin.
Inserting an internal dilator begins by ensuring both the device and your hands are clean, typically by washing them with warm water and mild soap. Some users wet the dilator or apply a small amount of nasal-safe lubricant to the tips for a more comfortable insertion. Gently slide the dilator into each nostril, positioning it so the “wings” or cones sit just inside the nasal passage.
The device is correctly placed when the connecting piece rests comfortably against the nasal septum, and the dilator expands to gently widen the nasal entrance without causing pain. If the device has adjustable features, fine-tune the expansion until you feel an immediate increase in airflow but no severe pressure or discomfort. The goal is to achieve a snug fit that stays securely in place without obstructing airflow.
Selecting the Correct Size and Fit
Finding the appropriate size for a nasal dilator is paramount for both effectiveness and comfort. A dilator that is too small will not provide enough outward pressure to adequately open the nasal passages, rendering it ineffective. Conversely, a device that is too large will cause excessive pressure on the nasal walls, leading to pain, irritation, and potential displacement.
For first-time users, purchasing a starter pack containing small, medium, and large sizes is highly recommended. This allows for a trial-and-error approach to determine the size that provides the optimal balance between a secure fit and maximal airflow. While some manufacturers provide sizing guides, personal trial is often necessary.
A poor fit is identifiable if the device falls out during sleep, causes significant soreness, or if breathing improvement is negligible. If the dilator feels like it is blocking the nostril instead of widening it, the size or angle of insertion needs adjustment. Internal dilators with customizable features, such as adjustable paddles or moldable material, offer a more personalized fit and may be suitable for individuals with asymmetrical or unique nasal shapes.
External nasal strips are also available in different sizes, typically standard and large, to accommodate varying nose shapes. The large size is recommended for individuals with a wider nose or those who feel the standard strip does not cover enough surface area. If the edges of the strip lift easily or cause skin irritation upon removal, it may indicate the strip is the wrong size or the skin was not properly cleaned.
Maintenance and Safe Usage
Proper maintenance of reusable internal nasal dilators is necessary to maintain hygiene and extend the product’s lifespan. After each use, the device should be cleaned with warm water and a mild, non-abrasive liquid soap to remove mucus and debris. Rinse the dilator thoroughly to ensure no soap residue remains, as this can irritate the delicate nasal lining.
Always allow the internal dilator to air-dry completely before storing it in a clean, dry case, which helps prevent the growth of bacteria and mold. Internal dilators typically need replacement every 60 to 90 days, or when the material begins to degrade or loses elasticity. External nasal strips are designed for single use and must be discarded after removal.
Certain precautions should be observed to ensure safe usage. Discontinue use immediately if the device causes significant pain, persistent irritation, or triggers nosebleeds. If the dilator does not alleviate breathing issues, or if symptoms such as chronic snoring or congestion persist, consult a healthcare provider, such as an Ear, Nose, and Throat (ENT) specialist. Nasal dilators should only be used by one person to prevent the transfer of germs and must be kept out of reach of small children due to the choking hazard.
