A laryngectomy tube is a short, lightweight plastic tube placed inside the stoma (the surgically created opening in the neck) after the voice box has been removed. Its primary job is to keep that opening from narrowing or closing as it heals, because after a total laryngectomy the stoma is your only airway. Unlike a temporary breathing tube, a laryngectomy tube sits entirely in the neck and is much shorter, since it only needs to bridge the short distance from the skin surface to the windpipe.
Why the Stoma Needs a Tube
During a total laryngectomy, surgeons remove the entire voice box and redirect the windpipe to an opening in the front of the neck. Once the voice box is gone, there is no longer any connection between the windpipe and the mouth or nose. You breathe exclusively through the stoma.
Scar tissue can gradually shrink the stoma, a process called stenosis. A laryngectomy tube acts as a stent, holding the opening at a stable diameter so air flows freely. Most people wear a tube full-time in the weeks and months after surgery. Some eventually stop using one once the stoma matures and stays open on its own, while others wear a tube indefinitely if their stoma tends to narrow.
How It Differs From a Tracheostomy Tube
The two devices look similar but serve very different situations. A tracheostomy tube passes through an incision in the neck into a windpipe that still connects to the mouth and nose. If the tracheostomy tube comes out or gets blocked, the patient can still get air through the upper airway in many cases. A laryngectomy tube, by contrast, sits in a person whose upper airway has been permanently disconnected from the lungs. No air reaches the lungs through the mouth or nose, period.
This distinction has serious practical consequences. A face mask or nasal cannula will not deliver oxygen to someone with a laryngectomy. In an emergency, all airflow must go through the stoma. Laryngectomy tubes are also shorter and often lack the inflatable cuff found on many tracheostomy tubes, because they don’t need to seal against ventilator pressure the same way.
Materials and Design
Most modern laryngectomy tubes are made from medical-grade silicone. Silicone is soft, durable, and lightweight, which matters for a device that sits against delicate tissue for hours at a time. Some brands, like the Blom-Singer line, are specifically designed to be flexible enough to fit comfortably inside the stoma without pressing hard against the walls.
Tubes come in a range of sizes based on inner diameter, outer diameter, and length. Your surgical team selects a size by measuring the stoma and the depth of the tissue between the skin surface and the windpipe. A tube that’s too large causes irritation; one that’s too small won’t prevent narrowing. Sizing is usually checked at follow-up visits and adjusted as swelling goes down in the weeks after surgery.
Breathing Without a Nose: The Role of HMEs
Your nose normally warms, moistens, and filters the air before it reaches your lungs. After a laryngectomy, air enters the windpipe directly through the stoma, bypassing all of that conditioning. The result is predictable: frequent coughing, excess mucus production, irritation of the windpipe, higher risk of chest infections, and disrupted sleep.
A heat and moisture exchanger (HME) solves much of this problem. It’s a small cassette with a foam core that sits over the stoma opening, often housed right inside the laryngectomy tube or attached to an adhesive baseplate on the skin. When you exhale, the foam traps warmth and humidity. When you inhale, that stored heat and moisture transfers to the incoming air. The foam also filters dust and small particles. People who use an HME consistently report less mucus, less coughing, better sleep, and easier breathing overall.
Daily Cleaning and Stoma Care
Keeping the tube and stoma clean is one of the most important parts of life after laryngectomy. Mucus and dried crusts can accumulate inside the tube and along the walls of the stoma, potentially blocking airflow. A good routine involves checking the stoma with a flashlight and mirror every morning and evening, looking for crusts or buildup.
The basic steps are straightforward:
- Wash the skin around the stoma gently with mild soap and water, then pat dry.
- Use saline spray directly into the stoma every two to three hours to keep the airway moist, especially in the early months while the tissue is still healing.
- Remove mucus by coughing, inhaling steam from a hot shower or sink, or placing a warm, damp cloth over the stoma to loosen dried secretions.
- Clean the tube itself according to your care team’s instructions, typically by removing the inner cannula (if it has one) and rinsing it.
Humidity drops at night, so crusting tends to worsen while you sleep. Running a humidifier in the bedroom and wearing a stoma cover both help. The inside of a well-maintained stoma should look pink and glistening, similar to the inside of your mouth.
How Often Tubes Are Replaced
Laryngectomy tubes don’t last forever. Silicone degrades over time, and buildup from mucus and bacteria can make the surface rough. For people who manage their care well, tube exchanges every six months are typical. If keeping the tube clean is more difficult, or if mucus production is heavy, exchanges every one to three months may be needed. Your care team will set a schedule based on how your stoma looks at follow-up appointments.
Living With a Laryngectomy Tube
The tube itself is not painful once the surgical site heals, though it can feel unfamiliar at first. Some people find that wearing a stoma cover over the tube helps them feel more comfortable in public, and it doubles as a basic filter against dust and cold air. Swimming and water activities require special precautions, since water entering the stoma goes straight to the lungs.
Communication changes significantly after a total laryngectomy because the voice box is gone. A laryngectomy tube doesn’t restore speech on its own, but it can work alongside devices that do. Some people use a small one-way valve inserted through the stoma wall that redirects air into the throat for speech. Others learn esophageal speech or use a handheld electrolarynx. The tube’s role in communication is mostly structural: keeping the stoma open and stable so these other methods can work reliably.
Not everyone needs a laryngectomy tube permanently. Once the stoma has fully healed and maintains its size without support, some people transition to a stoma button (a shorter, less prominent device) or stop wearing anything in the opening altogether. That decision depends on how the tissue behaves over months of healing and is made gradually with input from your surgical team.
