Understanding What Goes In Your Mouth During Surgery
It's a common question, and perhaps a slightly unsettling one: what exactly do medical professionals place in your mouth when you're undergoing surgery? The answer isn't a single item, but rather a range of devices and tools, each with a specific purpose. These instruments are crucial for maintaining a clear airway, allowing the surgical team to operate effectively, and ensuring your safety throughout the procedure. Let's break down the most common items you might encounter, depending on the type of surgery you're having.
Airway Management: The Top Priority
The primary reason something is placed in your mouth during many surgeries is to ensure you can breathe properly. When you're under anesthesia, your muscles relax, including those that keep your airway open. Without intervention, your tongue could fall back and block your airway, making it impossible to breathe.
1. Oral Airway (Oropharyngeal Airway)
This is one of the most frequently used devices. An oral airway is a curved piece of plastic or rubber that is inserted into the mouth and extends down to the back of the throat. Its purpose is to physically hold the tongue away from the back of the throat, preventing it from obstructing the airway.
- Material: Typically made of sturdy, yet flexible, plastic or rubber.
- Design: It has a flange that rests outside the mouth, preventing it from being swallowed. The hollow lumen allows air to pass through.
- Sizing: Oral airways come in various sizes, and the anesthesiologist will select the appropriate size based on your anatomy to ensure a proper fit and effective airway management.
2. Bite Block
Sometimes, a bite block is used in conjunction with or instead of an oral airway. This is a device, often made of plastic or rubber, that is placed between the teeth. Its main functions are:
- Preventing Tongue Injury: It prevents your tongue from being bitten during the procedure, especially if there are involuntary muscle movements or during emergence from anesthesia.
- Securing Airways: In some cases, it can help to keep an endotracheal tube (more on that below) from being occluded by the teeth.
- Facilitating Access: For certain oral or dental surgeries, a bite block can help the surgical team access the oral cavity more easily by keeping the mouth open.
Endotracheal Tube (ETT)
For more complex or longer surgeries, or when complete control of the airway is necessary, an endotracheal tube is often used. This is a flexible tube that is inserted through the mouth (or sometimes the nose) and down into the trachea (windpipe).
- Purpose: The ETT allows the anesthesiologist to directly control your breathing. It's connected to a ventilator, which delivers oxygen and anesthetic gases to your lungs and removes carbon dioxide.
- Placement: The anesthesiologist uses a laryngoscope to visualize the vocal cords and carefully guides the ETT into place.
- Cuff: Most ETTs have a small balloon cuff near the end that is inflated once the tube is in position. This cuff seals the airway, preventing stomach contents from entering the lungs (aspiration) and ensuring that the anesthetic gases are delivered directly to the lungs.
- Discomfort: You won't feel the ETT during surgery because you'll be under general anesthesia. However, you might experience a sore throat, hoarseness, or a cough after the tube is removed, which is a common side effect.
Other Potential Items
Depending on the specific surgical procedure, other items might be placed in or around your mouth:
1. Suction Catheters
These are thin, flexible tubes used to suction out excess saliva, blood, or secretions from your mouth and throat. This is essential for maintaining a clear surgical field and a clear airway.
2. Surgical Instruments for Oral Procedures
If you are undergoing surgery on your mouth, teeth, or jaw, then specialized surgical instruments will be used. These could include retractors to hold tissues back, drills, scalpels, forceps, and other tools directly involved in the surgical manipulation of tissues within the oral cavity.
3. Nasopharyngeal Airway
While less common for mouth-related procedures, a nasopharyngeal airway is a tube inserted through the nose and into the pharynx. It's an alternative to an oral airway in certain situations where an oral airway might be difficult to use or less effective. It also helps keep the airway open.
The Role of the Anesthesiologist
It's important to remember that the anesthesiologist is the medical professional primarily responsible for managing your airway during surgery. They are highly trained to assess your individual anatomy and medical history to determine the safest and most effective method for airway management. They will explain the process to you before the surgery and ensure your comfort and safety throughout.

Frequently Asked Questions (FAQ)
How do they decide which airway device to use?
The anesthesiologist considers several factors, including the type of surgery, the length of the procedure, your anatomy, your medical history, and your predicted airway difficulty. They will choose the device that best ensures a clear and safe airway for your specific situation.
Will I feel pain when they put these devices in my mouth?
You will be given anesthesia before any of these devices are inserted, so you will not feel pain or discomfort during the procedure. The anesthesia will render you unconscious and pain-free.
What is the purpose of the flange on an oral airway?
The flange is the part of the oral airway that rests outside your mouth. Its main purpose is to prevent the airway from being accidentally swallowed during the procedure.
Can these devices damage my teeth?
While there's always a minimal risk with any medical procedure, anesthesiologists are trained to insert these devices carefully to minimize the chance of dental damage. Bite blocks are often used to protect teeth, especially when an endotracheal tube is in place.
