The butterfly-shaped thyroid gland at the base of your neck and the four tiny parathyroid glands located behind it play crucial roles in regulating your body’s metabolism and calcium balance. When these glands malfunction, they can cause a wide range of symptoms affecting nearly every system in your body. Proper diagnosis and treatment by an experienced specialist is essential for restoring balance and health.

Dr. Michael Cohen provides comprehensive care for thyroid and parathyroid disorders throughout Long Island, combining his extensive ENT expertise with advanced diagnostic techniques and surgical skills.

What Are Thyroid and Parathyroid Disorders?

The thyroid and parathyroid glands, though located near each other, serve distinct functions in the body and can develop different disorders.

Thyroid Disorders

The thyroid gland produces hormones that regulate metabolism, energy use, and numerous other bodily functions. Common thyroid disorders include:

  • Hyperthyroidism:An overactive thyroid produces excessive thyroid hormones, accelerating the body’s metabolism. Graves’ disease, an autoimmune condition, is the most common cause, though toxic nodules and thyroiditis can also trigger hyperthyroidism.
  • Hypothyroidism An underactive thyroid produces insufficient thyroid hormones, slowing metabolism. Hashimoto’s thyroiditis, an autoimmune disorder, is the leading cause in the United States, though iodine deficiency remains a significant cause worldwide.
  • Thyroid Nodules: Abnormal growths within the thyroid gland can be solid or fluid-filled. While most are benign, approximately 5-10% may be cancerous, requiring thorough evaluation and possible surgical removal.
  • Goiter: An enlargement of the thyroid gland, often visible as a swelling in the neck, can result from iodine deficiency, Graves’ disease, Hashimoto’s thyroiditis, or multinodular growth. Large goiters may cause compression symptoms affecting breathing or swallowing.
  • Thyroid Cancer: Several types of cancer can affect the thyroid gland, with papillary thyroid cancer being the most common. Early detection and appropriate treatment generally lead to excellent outcomes.

Parathyroid Disorders

The four parathyroid glands regulate calcium levels in the blood and bones through the production of parathyroid hormone (PTH). Common parathyroid disorders include:

  • Hyperparathyroidism: Excessive production of parathyroid hormone, usually from a benign tumor (adenoma) on one of the four glands, causes elevated blood calcium levels. This can lead to kidney stones, bone fragility, digestive symptoms, and neurological issues.
  • Hypoparathyroidism: Inadequate production of parathyroid hormone results in abnormally low calcium levels, which can cause muscle cramps, tingling sensations, and in severe cases, seizures or heart rhythm abnormalities.
  • Parathyroid Cancer: Extremely rare, this malignancy accounts for less than 1% of cases of hyperparathyroidism but requires aggressive treatment due to its potential to spread to other organs.

Common Symptoms and Concerns

Thyroid and parathyroid disorders often present with distinctive symptoms that can significantly impact quality of life:

Hyperthyroidism Symptoms

  • Unexplained weight loss despite increased appetite
  • Rapid or irregular heartbeat
  • Nervousness, anxiety, and irritability
  • Heat intolerance and increased sweating
  • Tremors in the hands and fingers
  • Difficulty sleeping and fatigue
  • Enlarged thyroid gland (goiter)

Hypothyroidism Symptoms

  • Unexplained weight gain
  • Fatigue and increased sensitivity to cold
  • Dry skin and hair
  • Slowed heart rate and constipation
  • Muscle weakness and aches
  • Depression and impaired memory
  • Enlarged thyroid gland (goiter)

Parathyroid Disorder Symptoms

  • Kidney stones
  • Bone pain and fragility
  • Abdominal pain and digestive issues
  • Excessive urination
  • Fatigue and weakness
  • Memory problems and difficulty concentrating
  • Muscle cramps and tingling sensations

Treatment Options for Thyroid Disorders

Dr. Cohen develops personalized treatment plans based on your specific condition, symptoms, and preferenc es:

Medication Therapy

  • Antithyroid Medications For hyperthyroidism, drugs like methimazole block the production of excess thyroid hormones.
  • Thyroid Hormone Replacement For hypothyroidism, synthetic thyroid hormone (levothyroxine) replaces what the body isn’t producing naturally.
  • Beta-Blockers These medications can help manage symptoms of hyperthyroidism such as rapid heart rate and tremors while other treatments take effect.

Radioactive Iodine Treatment

For hyperthyroidism, particularly Graves’ disease, radioactive iodine can be taken orally to gradually shrink the overactive thyroid tissue. This approach often leads to hypothyroidism, requiring lifelong thyroid hormone replacement.

Surgical Management

Dr. Cohen specializes in surgical approaches to thyroid disorders when necessary:

  • Thyroid Lobectomy: Removal of half the thyroid gland, typically performed when nodules or cancer affect only one lobe.
  • Total Thyroidectomy: Complete removal of the thyroid gland, recommended for thyroid cancer, large goiters causing compression symptoms, or certain cases of hyperthyroidism.
  • Minimally Invasive Techniques: When appropriate, Dr. Cohen utilizes approaches that minimize incision size and recovery time while maximizing outcomes.

All thyroid surgeries are performed with meticulous attention to preserving the recurrent laryngeal nerves (which control the vocal cords) and the parathyroid glands to maintain normal voice and calcium balance.

Treatment Options for Parathyroid Disorders

Hyperparathyroidism Management

Parathyroidectomy: The definitive treatment for primary hyperparathyroidism is surgical removal of the affected gland(s). Dr. Cohen is skilled in:

  • Minimally Invasive Parathyroidectomy: Using small incisions and specialized techniques to remove the abnormal gland while minimizing recovery time.
  • Four-Gland Exploration: A comprehensive approach when multiple glands are affected or when localization studies are inconclusive.
  • Intraoperative PTH: Monitoring Blood tests during surgery confirm the successful removal of all abnormal parathyroid tissue.

Hypoparathyroidism Management

  • Calcium and Vitamin D Supplementation: Carefully monitored supplementation helps maintain appropriate calcium levels.
  • Regular Monitoring: Ongoing laboratory testing ensures that calcium levels remain within the target range.

What to Expect During Surgery

Dr. Cohen ensures that patients are thoroughly prepared for thyroid or parathyroid surgery:

  • Pre-Operative Evaluation: Comprehensive testing and assessment to ensure you’re an appropriate candidate for surgery.
  • Surgical Planning: Dr. Cohen explains the specific procedure, including the approach, expected outcomes, and potential risks.
  • The Procedure: Most thyroid and parathyroid surgeries are performed under general anesthesia and take between 1-3 hours, depending on complexity.
  • Recovery Process: Many patients can return home the same day, though overnight observation may be recommended in certain cases. Most individuals can return to non-strenuous activities within 1-2 weeks.
  • Follow-Up Care: Regular appointments monitor healing and hormone levels, with medication adjustments as needed to maintain optimal health.

Frequently Asked Questions About Thyroid and Parathyroid Disorders

If you undergo a total thyroidectomy, you will need lifelong thyroid hormone replacement. After a thyroid lobectomy, approximately 30% of patients require hormone supplementation, while the remaining 70% maintain adequate hormone production from the remaining lobe.

Dr. Cohen places incisions in natural skin creases where possible and uses advanced closure techniques to minimize scarring. Most patients develop a thin line that fades significantly over time. Scar management strategies can further improve the cosmetic outcome.

Many benign thyroid nodules can be safely monitored with regular ultrasound examinations rather than immediately removed. The decision depends on factors including the nodule’s size, appearance on imaging, FNA biopsy results, and whether it causes symptoms.

For medication treatments of thyroid disorders, improvement typically begins within 2-3 weeks, with full benefit in 6-12 weeks. After parathyroid surgery for hyperparathyroidism, calcium levels normalize rapidly, though symptom improvement varies from immediate relief to gradual improvement over several months.

Untreated hyperthyroidism can lead to heart problems, bone loss, and a dangerous condition called thyroid storm. Untreated hypothyroidism may cause high cholesterol, heart failure, and in extreme cases, life-threatening myxedema coma. Untreated hyperparathyroidism increases risk for kidney stones, osteoporosis, and cardiovascular complications.
