Thyroid nodules are a common medical condition that affects many people, especially women.
While most nodules are benign, they can cause discomfort or even grow large enough to obstruct the airway or esophagus. Ablation, a minimally invasive procedure that uses heat to destroy thyroid nodules, has become an increasingly popular treatment option for patients.
In an interview with Dr. Ghazi, an endocrinologist and thyroid disease specialist from Egypt, the topic of discussion was comparing microwave ablation to radiofrequency ablation (RFA) for treating thyroid nodules. Dr. Ghazi has successfully completed over 100 cases of thermal ablation of both microwave and RFA, making him an expert in the field.
When comparing the two ablation methods, Dr. Ghazi notes that both microwave ablation (MWA) and RFA are effective in treating thyroid nodules. However, the most significant difference between the two methods is the ablation type. Microwave is more rapid and has a shorter application time, which makes it less exhausting for the patient. In contrast, RFA requires a longer application time, which can be more taxing for the patient.
Another important factor to consider when choosing between microwave ablation (MWA) and RFA is the location of the nodule. RFA has a heat sink effect, which can make it less effective for nodules located near large arteries or blood vessels. In contrast, microwave ablation is not affected by this issue, and the location of the nodule is less of a concern.
Additionally, patients who undergo microwave ablation do not need to lie on a bed or footbed, making the procedure more comfortable and convenient for them. Furthermore, microwave ablation can be used on patients with pacemakers, epilepsy, and even pregnant women, whereas RFA should be avoided in these cases.
Finally, the size of the needle or antenna used in the procedure is also an important factor to consider. The antenna used in microwave ablation is larger and easier to see on ultrasound or biopsy, whereas the tip of the needle used in RFA is more easily visible by biopsy.
In conclusion, both microwave ablation and RFA are effective methods for treating thyroid nodules. The decision to choose one over the other depends on the location of the nodule, the expertise of the doctor, and the safety concerns for the patient. It is essential to consult with a qualified physician to determine the best course of treatment for individual patients. Thanks to Dr. Ghazi for sharing his expertise on this important topic.

About Philip James
In 2013, his laryngeal nerve was severed, shoulder nerve damaged, parathyroids ruined, and residual cancer left behind — all for a 1 cm thyroid nodule.
Later, a vocal cord implant was inserted to help him speak.
The word he uses to describe his work as patient advocate is, ‘tonglen’. Or, using his pain and hardship to help others.
