== Anatomy ==
A '''transesophageal echocardiogram''' (TEE) is a type of [[echocardiography]] that provides detailed images of the heart and its structures. Unlike a standard [[transthoracic echocardiogram]], TEE involves inserting a specialized probe into the [[esophagus]], which is located close to the heart, allowing for clearer and more precise images.


The '''Thyroarytenoid muscle''' originates from the lower margin of the [[thyroid cartilage]] and the adjacent cricothyroid ligament and inserts into the base and anterior surface of the [[arytenoid cartilage]].
== Procedure ==


The muscle is divided into two parts. The lower and larger part is the '''vocalis muscle''', which extends from the vocal ligament to the vocal process of the arytenoid. The upper and smaller part is the '''muscle of the ventricle''', which extends from the thyroid cartilage just above the vocal ligament to the anterior surface of the arytenoid.
The TEE procedure begins with the patient being sedated to ensure comfort. A flexible probe with an ultrasound transducer at its tip is then gently guided down the throat into the esophagus. This position allows the transducer to capture high-resolution images of the heart without interference from the [[ribs]] or [[lungs]].


== Function ==
=== Indications ===


The '''Thyroarytenoid muscle''' functions to relax the vocal folds. When the muscle contracts, it pulls the arytenoid cartilage forward towards the thyroid, which relaxes the vocal folds and decreases the pitch of the voice.
TEE is particularly useful in diagnosing and evaluating conditions such as:
* [[Endocarditis]]
* [[Congenital heart defects]]
* [[Aortic dissection]]
* [[Valvular heart disease]]
* [[Cardiac masses]]


== Clinical significance ==
=== Advantages ===


Damage to the '''Thyroarytenoid muscle''' can result in a variety of voice disorders, including [[hoarseness]], [[voice fatigue]], and [[vocal fold paralysis]]. Treatment options include voice therapy, surgery, and in some cases, [[botulinum toxin]] injections.
The proximity of the esophagus to the heart allows TEE to provide superior image quality compared to transthoracic echocardiography. This makes it invaluable in situations where detailed visualization of the heart's structures is necessary.

Transesophageal Echocardiogram[edit]

A transesophageal echocardiogram (TEE) is a type of echocardiography that provides detailed images of the heart and its structures. Unlike a standard transthoracic echocardiogram, TEE involves inserting a specialized probe into the esophagus, which is located close to the heart, allowing for clearer and more precise images.

Procedure[edit]

The TEE procedure begins with the patient being sedated to ensure comfort. A flexible probe with an ultrasound transducer at its tip is then gently guided down the throat into the esophagus. This position allows the transducer to capture high-resolution images of the heart without interference from the ribs or lungs.

Indications[edit]

TEE is particularly useful in diagnosing and evaluating conditions such as:

Advantages[edit]

The proximity of the esophagus to the heart allows TEE to provide superior image quality compared to transthoracic echocardiography. This makes it invaluable in situations where detailed visualization of the heart's structures is necessary.

Risks and Complications[edit]

While TEE is generally safe, it does carry some risks, including:

  • Sore throat
  • Esophageal perforation
  • Bleeding
  • Reaction to sedation

Patients are monitored closely during and after the procedure to manage any potential complications.
