Clinical Practice

As an Endocrine (thyroid, parathyroid, adrenal) surgeon, Professor Stan Sidhu performs more than 500 elective thyroid, parathyroid, salivary gland, and adrenal operations per year. He is a thyroid surgeon who offers total thyroidectomy for patients with multinodular goitre and Graves’ disease, total thyroidectomy and central and lateral neck dissection for patients with papillary and medullary thyroid cancer, and minimally invasive thyroidectomy for patients with atypical nodules and toxic nodules. All patients undergoing thyroidectomy will routinely have neuro-monitoring of the recurrent and external laryngeal nerves. Currently 1/1000 patients only have permanent voice change following thyroid surgery (published data) due to meticulous technique and advanced neuromonitoring technology. This is a significant advance for singers, teachers, corporate speakers and other voice professionals.

With vast experience as an Endocrine (thyroid, parathyroid and adrenal) surgeon, Professor Sidhu specialises in minimally invasive (keyhole) parathyroidectomy for patients with sporadic primary hyperparathyroidism and keyhole adrenal surgery utilising either laparoscopic or retroperitoneal endoscopic access for patients with small functional adrenal tumours. Open adrenalectomy and retroperitoneal lymph node surgery is undertaken for adrenal cancers and malignant phaeochromocytoma. Patients with salivary gland tumours are offered parotidectomy and submandibular gland resection plus neck dissection if required.

Professor Sidhu works as an Visiting Medical Officer surgeon at Royal North Shore and Hornsby hospitals.


After obtaining his medical degree with Honours at Sydney University, he completed his General Surgery Fellowship in Sydney and then undertook his International Endocrine Surgery Fellowship in Belfast, Northern Ireland. On return to Sydney, he completed a doctoral thesis examining the molecular genetics of Adrenocortical Tumours. His extensive research and practice has made him a world recognised Academic Endocrine Surgeon (thyroid, parathyroid and adrenal  specialist). Following the completion of his PhD he was appointed to Royal North Shore and Hornsby Hospitals.


As an eminent thyroid specialist, Professor Sidhu trains and educates medical students and residents and has also mentored over 40 surgeons as Fellows in Endocrine Surgery, as surgeons obtaining their General Surgery Fellowship and as surgeons undertaking a doctoral thesis in Thyroid and Adrenal molecular biology research.
