Microwave ablation (MWA) is an advanced technique for treating thyroid nodules. It generates high heat to ablate abnormal tissue. It is particularly beneficial for larger nodules due to its ability to deliver intense heat quickly, making the procedure faster and potentially more effective in reducing nodule size.

What is Microwave Ablation?
Microwave ablation is a promising alternative to traditional surgical treatments for thyroid nodules. It involves inserting a thin needle into the nodule and delivering microwave energy, which heats and destroys the abnormal tissue. This procedure is performed under local anesthesia and a sedative and typically takes less than an hour.
Benefits of Microwave Ablation
Microwave ablation offers several advantages over traditional treatments for thyroid nodules, including:
- Minimally invasive: MWA is a less invasive option compared to surgery, with a shorter recovery time and fewer risks of complications.
- Effective for larger nodules: MWA can generate higher temperatures than radiofrequency ablation (RFA), making it potentially more effective for larger nodules.
- Preserves thyroid function: In many cases, MWA can help reduce the size of the nodule without affecting thyroid function.
- Outpatient procedure: Microwave ablation can be performed on an outpatient basis, which means you can go home the same day as the procedure.
Effectiveness for Large Nodules
MWA is especially effective for large thyroid nodules, as it can generate higher levels of heat compared to other methods. This increased heat allows for quicker treatment times and may lead to better outcomes in reducing the size of larger nodules.
Considerations for Nodules Near Sensitive Structures
While MWA is highly effective, there are concerns when using it for nodules located near sensitive structures, such as nerves. The high heat generated by MWA could increase the risk of nerve damage if not performed with extreme precision. Therefore, in cases where the nodule is close to nerves, it may be preferable to use a method that generates less heat, like RFA, to minimize the risk of injury. Dr Kandil will make the best decision for your case.
What to Expect Before, During, and After the Procedure
Pre-Procedure Evaluation
- Imaging Tests: Before the procedure, imaging tests are performed to assess the size, location, and characteristics of the thyroid nodule.
- Consultation: Dr. Kandil will discuss the procedure in detail, including the benefits, risks, and what to expect during recovery. He will also review your medical history and any medications you are taking.
During the Procedure
- Anesthesia and Sedation: MWA can be performed under conscious sedation, allowing patients to remain awake but comfortable during the procedure.
- Microwave Ablation: Using ultrasound guidance, a fine needle is inserted into the nodule. Microwave energy is then delivered through the needle, generating heat that ablates the abnormal thyroid tissue. The procedure typically lasts 30 to 60 minutes, depending on the size and number of nodules.
Post-Procedure Care
- Observation: After the procedure, you will be monitored for a short period to ensure there are no immediate complications.
- Recovery: Most patients experience mild discomfort, which can be managed with over-the-counter pain relievers.
- Follow-Up: A follow-up ultrasound is scheduled to monitor the reduction in nodule size and assess the success of the treatment.
Is Microwave Ablation Right for You?
Microwave ablation is not appropriate for everyone with a thyroid nodule. Dr. Kandil will work with you to determine if microwave ablation is the right treatment option for you. Factors that may influence this decision include:
- The size and location of the nodule.
- Your overall health.
