Thyroid nodules are a common thyroid disorder, affecting a significant portion of the population. While most nodules are benign, some can cause symptoms or be indicative of thyroid cancer. In the field of otolaryngology, ethanol injections have emerged as a minimally invasive and effective treatment option for certain thyroid nodules. In this blog post, we explore the use of ethanol injections by Ear, Nose, and Throat (ENT) specialists and shed light on their benefits and considerations.

Understanding Ethanol Injections:

Ethanol injections, also known as percutaneous ethanol injection therapy (PEI), involve the targeted injection of ethanol into thyroid nodules. The goal is that by causing cellular destruction the nodule will collapse and cause no more esthetic concerns and no more compressive symptoms.  This procedure is performed under ultrasound guidance to ensure precise placement of the injections.

Benefits of Ethanol Injections:

1. Effective for cystic and predominantly cystic nodules Nodules: Ethanol injections have shown excellent results in reducing the size of certain nodules that are causing esthetic concerns and/or giving compressive symptoms.
2. Minimally Invasive: Ethanol injections are considered a minimally invasive alternative to surgery, offering a lower risk of complications and faster recovery time.
3. Avoidance of General Anesthesia: Unlike surgical options, ethanol injections are performed under local anesthesia, reducing the risks associated with general anesthesia.
4. Outpatient Procedure: The procedure is typically performed in an outpatient setting, allowing patients to return home the same day and to go back to their regular activities very quickly.

Considerations:

While ethanol injections have shown positive outcomes, it is important to consider the following factors:

1. Nodule Characteristics: Not all nodules are suitable for ethanol injections. Solid nodules with a large solid component may not respond as well as cystic nodules.
2. Multiple Treatment Sessions: Ethanol injections may require multiple treatment sessions to achieve the desired results, spaced several weeks or months apart.
3. Potential Side Effects: Some patients may experience temporary pain, swelling, or voice changes after the procedure. However, these side effects are typically mild and temporary.
4. Monitoring and Follow-up: After the procedure, patients require regular monitoring through ultrasound examinations to evaluate the nodule’s response and ensure no adverse effects.

Ethanol injections performed by ENT specialists offer a safe and effective treatment option for select thyroid nodules. This minimally invasive procedure can significantly reduce the size of certain nodules, alleviating symptoms and avoiding the need for surgery in many cases. If you have thyroid nodules or are considering treatment options, consult with an ENT specialist to determine whether ethanol injections may be a suitable option for you. Together, you can make an informed decision about the best course of action to address your thyroid nodule concerns.
