Although anamnesis and physical examination remain the place in the evaluation of patients today; laboratory values, imaging methods and pathology results have come to the fore in the decision-making of surgery for patients. As a result of all other criteria, a follow-up decision can be changed in a patient with a single fine needle aspiration biopsy result, or despite all the examinations the investigators have, a clear result cannot be achieved, and patient management may be disrupted. A holistic approach to thyroid gland pathologies is planned thanks to the scoring system that will be created in this study.

In routine clinical practice, the criteria the investigators consider during the pre - op period in patients evaluated due to thyroid pathologies include anamnesis, physical examination, laboratory values, especially thyroid function, thyroid-neck ultrasonographies, fine needle aspiration biopsies, according to which decisions about operation or nonoperative follow-up are made with the patient. The investigators aim to create a common scoring system by taking into account the pathology results of patients who have undergone thyroidectomy and comparing these results with the results of pre-op examination and thus to address patient management in a more objective and comprehensive way.

Inclusion Criteria:

• patients who undergone surgery for thyroid gland pathologies

Exclusion Criteria:

• patients who did not want to be involved in the study
• patients who missed in the follow-up period
• pregnant patients

Thyroidectomy, which is a routine operation in clinic ( unilateral, total, complementary, etc.) ) applied patients will be included in the study
