Thyroid (Thyroidectomy)

Thyroidectomy is the removal of all or part of the thyroid gland. The thyroid gland is a butterfly shaped gland located at the front of the neck. It produces hormones that regulates metabolism.
Thyroidectomy may be recommended for a number of conditions:

  • Cancer – Once thyroid cancer has been diagnosed from a biopsy, removing part or all of the thyroid gland will be the treatment of choice. Surrounding lymph nodes may need to be removed during the same operation depending on the size of the cancer. Occasionally radioactive iodine treatment is offered after surgery depending on the final pathology result
  • Enlargement (Multinodular Goitre) – Removing part or the entire gland may be a treatment option if the enlarged gland causes difficulty in breathing and/or swallowing.
  • Overactive thyroid ( Hyperthyroidism/Graves’ disease) – In these conditions, the thyroid gland produces too much hormones. It can be treated by medication, radioactive iodine or surgery. Often surgery is recommended if you have problems with antithyroid medication and/or unsuitable for radioactive iodine treatment.

Parotidectomy is the surgical removal of part of the parotid salivary gland. The operation is performed under general anaesthesia. During the procedure, a skin incision will be made in front of the ear and down to the neck. In most cases, the cut will be along the skin crease to minimise the scar. The affected portion of the gland will be removed aiming to preserve the facial nerve which sits between two layers of the gland. Its preservation is important as it controls the muscles of the face. At the end of the operation, a drain will be placed through the wound. You can eat and drink after the operation. Most patients will stay between 1-2 days in the hospital and be able to return to work in 2 weeks.
