When is a Tracheostomy Needed for MSA Stridor?

When non-invasive breathing support like a CPAP or BiPAP machine is no longer enough to control severe stridor (a high-pitched, wheezing sound during breathing), a tracheostomy is the recommended medical step to secure your airway ^[1][2][3]. A tracheostomy is a surgical procedure that creates a small opening in the front of your neck and inserts a breathing tube directly into your windpipe. This bypasses the vocal cords entirely, ensuring that you can breathe safely even if your stridor worsens.

Why Stridor Progresses in MSA

Stridor in multiple system atrophy (MSA) is primarily caused by vocal cord abductor paralysis (VCAP) ^[2][1][4]. This means the muscles that normally pull your vocal cords open when you breathe in become weak or paralyzed. Instead of opening wide to let air through, the vocal cords stay close together, narrowing the airway and creating the high-pitched sound.

As MSA progresses, this vocal cord paralysis can worsen. Eventually, the narrowing can become severe enough that a CPAP (Continuous Positive Airway Pressure) machine can no longer push enough air past the vocal cords ^[5][3][1].

Facing this progression can be incredibly frightening. It is important to know that when the airway becomes severely narrowed, there is a high risk it could become completely blocked—particularly at night. If left untreated, this can lead to life-threatening respiratory emergencies, suffocation, or sudden death ^[2][1][4]. Understanding this reality is the first step toward protecting yourself.

While other vocal cord procedures exist (like laser surgery or Botox to hold the cords open), they are generally avoided in MSA. This is because opening the vocal cords permanently greatly increases the risk of food or liquid entering the lungs (aspiration). This is especially dangerous since MSA frequently causes swallowing difficulties (dysphagia) ^[1][6].

The Role of a Tracheostomy

A tracheostomy provides a definitive, secure airway. By placing a tube below the level of the vocal cords, it completely removes the danger of your vocal cords closing and blocking your breath ^[6][1][4].

Survival and Sudden Death
Getting a tracheostomy can prolong your survival by preventing acute respiratory failure ^[6][7]. In some cases, a mechanical ventilator may eventually be attached to the tracheostomy tube to help pump air into the lungs, which has also been shown to extend survival ^[6][7].

However, while a tracheostomy solves the immediate problem of a blocked airway, it does not stop the underlying progression of MSA ^[8][1]. Because MSA affects the autonomic nervous system (which controls automatic functions like heart rate and blood pressure), a tracheostomy reduces, but does not completely eliminate, the risk of sudden death ^[6][1].

What to Expect: Surgery and Daily Life

The decision to get a tracheostomy is a major one and deeply personal. It requires balancing the safety of a secure airway with the practical and emotional impacts on your daily life ^[9][1].

The Procedure and Recovery
The surgery is typically done under general anesthesia in a hospital. Following the procedure, you will likely spend one to two weeks in the hospital while your medical team monitors your healing, ensures the tube size is correct, and—most importantly—teaches you and your family how to care for it before you go home.

Impact on Daily Life
Important daily considerations include:

• Communication: A standard tracheostomy tube bypasses the vocal cords, meaning air no longer passes through them to create sound. While specialized one-way valves (speaking valves) exist, they are often unsafe for MSA patients with severe vocal cord paralysis. Because your vocal cords remain paralyzed in a closed position, a speaking valve can cause dangerous air-trapping in your lungs ^[10][11]. You should prepare for alternative ways to communicate, such as using text-to-speech apps on a tablet, writing boards, or specialized communication devices.
• Daily Care Burden: The tracheostomy tube requires rigorous daily maintenance. You will need regular suctioning (using a small machine to clear mucus from the airway), which can be required multiple times throughout the day and night, especially in the weeks right after surgery ^[10][11][9]. This demanding routine often requires a dedicated family caregiver, a respiratory therapist, or skilled nursing support at home ^[10][11][9].
• Swallowing: A tracheostomy can change how swallowing feels. Since swallowing difficulty is already a common symptom in MSA, a speech and language therapist will work with you to help safely manage eating and drinking ^[12][13].

Making the Decision and Timing

Because MSA is a rapidly progressive condition, you should discuss a tracheostomy before it becomes an absolute emergency. Warning signs that it is time to seriously consider the surgery include: stridor occurring while you are awake during the day, feeling like you are fighting your CPAP machine to get air, or experiencing episodes of waking up gasping for breath despite using your CPAP ^[5][2].

Working with a palliative care team can be highly beneficial during this time ^[9][1]. They can help you and your family outline your goals of care—weighing the desire to extend your life against the desire to minimize invasive procedures and maintain comfort ^[9][1].
