Ultrasound is a useful tool for creating images or pictures of the thyroid and parathyroid glands. This technology uses sound waves instead of radiation to evaluate and follow thyroid nodules. Dr. Brady and Dr. Sabra perform in office ultrasounds during the first visit and FNA (fine needle aspiration) biopsy of thyroid nodules or lymph nodes if indicated. The ultrasound helps Austin Thyroid and Parathyroid Surgeons plan for the best surgical options for each patient.


Intraoperative (rapid) Parathyroid Hormone Level (PTH) Monitoring

Intraoperative parathyroid hormone (PTH) monitoring involves blood levels of parathyroid hormone that can be followed during surgery. Dr. Sabra and Dr. Brady  obtain a blood sample just prior to surgery and then at 5 and 10 minutes after the abnormal parathyroid gland is removed. If the blood level has dropped 50% to within the normal range, the operation is a success and complete. These rapid tests can ensure that patient’s disease is cured and no further dissection is required. It allows for focused operations with smaller incisions and shorter surgical times.

Recurrent Laryngeal Nerve Monitoring

Neck ultrasound and recurrent laryngeal nerve monitoring is used in nearly every operation that Dr. Brady and Dr. Sabra perform in the neck. This special technology allows them to protect and monitor the nerves that controls the voice box. While skill and experience are essential for successful thyroid and parathyroid surgery, laryngeal nerve monitoring adds an important level of safety.

High Definition Cameras

High definition cameras are technologic advances that enable surgeons to have magnified view of the operative field during minimally invasive video assisted operations.

Thyroid History

Goiters (or thyroid gland enlargement) were observed 4000 years ago in Egypt, China, Greece, and other countries.

In 1500, Leonardo da Vinci was the first person to recognize and draw the thyroid gland. He drew the thyroid as a globular, bilobate organ, which he described as two glands.

In modern times, the thyroid was first identified in 1656 by the anatomist Thomas Wharton (whose name is also in Wharton’s duct of the submandibular gland). During that same year, Thomas Wharton named the gland the thyroid, meaning shield, as its shape resembled the shields commonly used in Ancient Greece.

At the time of the French Revolution in 1791, Pierre-Joseph Desault from Paris reported the first known published account of the surgical removal of a thyroid goiter.

In 1909, Theodor Kocher from Switzerland won the Nobel Prize in Medicine “for his work on the physiology, pathology and surgery of the thyroid gland” He is commonly referred to as the father of thyroid surgery.

Henry Plummer at the Mayo Clinic introduced the use of iodine before surgery for patients with Graves’ disease and hyperthyroidism in 1923.

George Crile is credited with being the first surgeon to perform radical neck surgeries for tumors of the head and neck, including thyroid cancers.

Further improvements in medical treatment of thyroid disease took place in early 20th century when Edward Kindall from the Mayo Clinic in 1914 on Christmas day developed thyroxin, making the treatment of hypothyroidism simple and safe.

Parathyroid History

The parathyroid glands were first discovered in 1852 by Sir Richard Owen upon dissection of a rhinoceros that had died in the London zoo. He described the parathyroid gland as “a small compact yellow glandular body attached to the thyroid at the point where the veins emerged”. In 1880, Ivar Sandström, a 25 year old medical student working in Uppsala, first described the parathyroid glands in the human body.The importance of his discovery was not fully appreciated until Eugene Gley (1857–1930), a French physiologist, observed that the tetany and death caused by experimental thyroidectomy in dogs occurred only if the removed specimen included the parathyroid glands as described by Sandström.

It was not until 1915 when a pathologist in Vienna named Friedrich Schlagenhaufer suggested that an enlarged parathyroid might be the cause of bone disease.

Felix Mandl performed the first parathyroidectomy at the University Surgical Clinic of Vienna in July 1925. Using local anaesthesia, he excised a ‘yellowish-brown almond shaped tumour’ measuring 25×15×12 mm from the left inferior area behind the thyroid gland. The patient was found to have an immediate improvement. Within a few days the blood and urine calcium content was considerably lower and the patient was soon able to walk again.

In 1926 the first parathyroidectomy in the United States was performed by EJ Lewis at the Cook County Hospital in Chicago.

CaptainHowever, the most notable historical case of hyperparathyroidism was that of Captain Charles Martell, a New York City sea captain who had become disabled by demineralization of the skeleton over many years (Fig 1). Between 1926 and 1932 his case graphically illustrated many of the features of the disease and eventually led to its management.The patient underwent a series of six neck operations without success. It was Martell himself, who having researched extensively at the Harvard medical library about ectopic parathyroid disease, suggested to his surgeons that he undergo an open heart surgery where he anticipated the tumor would be located. The patient convinced his surgeons to perform one final operation and in 1932, the 3cm parathyroid tumor in the mediastinum (the center of the chest cavity next to the heart) was removed curing the Captain’s hypercalcaemia and becoming the first successful parathyroid surgery in the United States.
