Computed tomography of larynx

Can a CT scan detect laryngeal cancer?
Laryngeal SCC encroaching on both, the glottis and supraglottis, with or without subglottic component and when the site of origin is unclear, is termed as transglottic tumor [Figure 1.

Can a CT scan detect laryngeal cancer?
You might have a CT scan of your head and neck to show the size of your laryngeal cancer and any enlarged lymph nodes in your neck.
You might also have a CT scan of your chest or abdomen.
This can show whether the cancer has spread..
How do you evaluate the larynx?
The simplest form of laryngeal examination is called "indirect laryngoscopy".
The examiner can place a small mirror in the back of the throat and angle it down towards the larynx.
Light can be reflected downward and the larynx can be seen in the mirror..
How is the larynx examined?
Direct laryngoscopy uses a tube called a laryngoscope.
The instrument is placed in the back of your throat.
The tube may be flexible or stiff.
This procedure allows the doctor to see deeper in the throat and to remove a foreign object or sample tissue for a biopsy..
What is a CT of the larynx?
A CT scan is a test that uses x-rays and a computer to create detailed pictures of the inside of your body.
It takes pictures from different angles..
What is a CT scan of the throat and neck?
A neck CT scan uses a special X-ray machine to make images of the soft tissues and organs of the neck, including the muscles, throat, tonsils, adenoids, airways, thyroid, and other glands.
The blood vessels and upper spinal cord are also seen.
A person getting a CT scan lies on a table..
What is laryngeal imaging?
Laryngeal Imaging Allows SLPs to View Vocalization in Action
Endoscopy was originally developed to investigate the larynx and only later was adapted to looking at other internal organs.
As the first type of endoscopic imaging, it is also among the most common and most frequently used..
What is the best imaging of the larynx?
CT Imaging of the Larynx
Multidetector Computed Tomography (MDCT) is usually the first choice for cross-sectional imaging in the diagnostic workup of laryngeal lesions.
The advantages of MDCT is its ability for thin slices which provide high spatial resolution._{Oct 31, 2022}.
What is the CT protocol for larynx cancer?
The larynx protocol includes standard neck CT obtained during quiet breathing, plus repeat scanning through the larynx during breath-holding and straw-blowing.
The vocal cords normally adduct during breath-holding, while abducting in a paramedian location during quiet breathing..
Where is the larynx exact location?
The larynx is located about half way down our neck.
It can be thought of as a short tube.
At the top it is connected to the throat, and at the bottom it is attached to the windpipe, so it's a part of our respiratory system.
The inside of the larynx is lined with mucous membrane tissue..
It's called laryngeal palpation.
The ring finger goes on the patient's cricoid notch, the middle finger is on the Adam's Apple and the index finger is on the hyoid bone.
As the patient swallows, the SLP “feels” the hyolaryngeal movement and judges the speech of elevation.
Laryngeal Imaging Allows SLPs to View Vocalization in Action
Endoscopy was originally developed to investigate the larynx and only later was adapted to looking at other internal organs.
As the first type of endoscopic imaging, it is also among the most common and most frequently used.
Laryngoscopy is when a doctor uses a special camera to look down the throat to see the voice box (larynx) and vocal cords.
Ear, nose, and throat specialists (also called ENT doctors or otolaryngologists) do laryngoscopies.
The larynx protocol includes standard neck CT obtained during quiet breathing, plus repeat scanning through the larynx during breath-holding and straw-blowing.
The vocal cords normally adduct during breath-holding, while abducting in a paramedian location during quiet breathing.
The primary function of the larynx in humans and other vertebrates is to protect the lower respiratory tract from aspirating food into the trachea while breathing.
It also contains the vocal cords and functions as a voice box for producing sounds, i.e., phonation.

Oct 31, 2022This CT imaging guide covers the anatomy, pathologies, trauma, and CT protocols of the larynx and laryngeal space.

CT Imaging of the Larynx Multidetector Computed Tomography (MDCT) is usually the first choice for cross-sectional imaging in the diagnostic workup of laryngeal lesions. The advantages of MDCT is its ability for thin slices which provide high spatial resolution.

Using this technique the laryngeal structures of clinical relevance can be demonstrated with the help of at least 10 scans. It requires little time and the radiation exposure for the patient is minimal. The accuracy of CT measurements corresponds excellently to the anatomical features.

When imaging cancer of the larynx with CT, technologists should perform contrast-enhanced helical CT scanning from the C1 vertebral body to the thoracic inlet, with the section plane parallel to the true vocal cords or the hyoid bone.
