About the department

The department of thyroid surgery at Teknon Medical Center Barcelona offers a full range of medical services for patients with thyroid diseases and other endocrine surgery options. The department has the most famous and prestigious medical team of surgeons in Spain, consisting of more than 40 professionals, with a history of 28 years and performing more than 4,500 operations per year. The surgical model guarantees a personalized, patient-centred service and the best professional training, covering all types of pathologies. Surgeons specialize in minimally invasive, gentle thyroid surgical interventions performed under general anaesthesia. Interventions usually last from one to three hours. After, the patient remains in the anaesthesia recovery department for several hours under special supervision. With many patients per year (more than 1,500 patients), the department has zero mortality, which confirms the high professionalism of surgeons and the quality of medical services.

The department's specialists have a wealth of knowledge in treating benign and malignant tumours of the thyroid gland. The department has a committee on thyroid cancer, which includes endocrinologists, oncologists, surgeons, radiologists, pathologists, and nuclear medicine specialists. All cases are discussed and forwarded following internationally recognized protocols. In addition to oncological diseases, doctors provide excellent treatment for inflammatory and autoimmune thyroid diseases.
