Main Article Content
Abstract
For the management of the large in size benign thyroid nodules or causing local pressure symptoms, surgical resection is the best option.Although there are many possible complications of surgery or the general anesthesia could
happen to the patients even in the experienced hands. Minimal or noninvasive procedures for treatment of solid tumors have been investigated continuously, in order to make the alternative treatment planning decisions. There is an interest
in developing noninvasive treatment for thyroid nodules such as laser ablation, microwave ablation and radiofrequency ablation. Recently, High-intensity focused ultrasound (HIFU) has been suggested for thyroid nodules treatment
and reported some promising results. In addition to thyroid nodules, allergic rhinitis and several HIFU applications in the Head and Neck area are suggested.
Applications of ultrasound in medicine for the rapeutic purposes have been used for many years. HIFU is a noninvasive therapy and maybe an alternative to the surgical resections.Currently HIFU has the US-Federal and Drug
Administration approved for the treatment of uterine fibroids, essential tremor, painful bone metastases, prostate cancer and benign prostatic hyperplasia. Other indications such as liver,thyroid, pancreas, renal, brain, benign and
malignant tumor treatment and various medical conditions are being researched.
Reduction of tumor mass after HIFU treatment resulted from ultrasound energy absorbing in tissue during wave transmission induce a focused coagulative thermal necrosis along with nonthermal mechanisms. Target is damaged with minimal effect to surrounding tissues.
The purpose of this review is to provide a foundation of High-intensity focused ultrasound knowledge and applications.
