One RFA complication may include voice alteration and/or hoarseness, but most patients regain their original voice a few months after the RFA treatment.
Skin burn is a minor complication that was also reported in very few cases. At the site of the puncture, skin may change color slightly and patients may experience minor discomfort. The skin heals on its own within 2 weeks of the procedure.
Nausea and/or vomiting may occur after the procedure, but never during the treatment. One of the causes of feeling nauseous is due to the extension of the neck which may cause an imbalance of blood flow, resulting in nausea and/or vomiting. Other factors contributing to this complication may include age, gender, non-smoker, and a history of nausea.
A very rare complication is a ruptured nodule. This complication will not be noticed immediately but it may appear several weeks later. Pain will occur at the site of the procedure and the neck will be suddenly bulging. Antibiotics will usually help to heal a nodule rupture.
There have been no fatalities, no permanent changes in voice, no tracheal injury, esophageal injury, or any other major (life altering) complications.
