Solitary thyroid nodules are a common clinical finding, with diverse etiologies ranging from benign adenomas to malignancies. The management of these nodules often involves surgical intervention, with total thyroidectomy being a definitive treatment. This procedure offers the advantage of addressing both malignant and suspicious lesions while minimizing the risk of recurrence. However, it is associated with potential complications, including hypocalcemia and recurrent laryngeal nerve injury. A comprehensive review of the literature was conducted, examining clinical studies, meta-analyses, and guidelines. Emphasis was placed on patient selection criteria, preoperative evaluation, surgical techniques, and postoperative outcomes. Evidence indicates that total thyroidectomy is highly effective for solitary nodules with malignant or indeterminate cytology. It reduces the need for reoperation and provides clear pathology for diagnosis. Advances in surgical techniques and perioperative care have significantly reduced complication rates. However, complications remain a concern, particularly in patients with coexisting comorbidities or challenging anatomical variations. Total thyroidectomy is a valuable approach for managing solitary thyroid nodules, particularly those with a high risk of malignancy. Patient selection and surgical expertise are critical in optimizing outcomes and minimizing complications. Further research is needed to refine surgical indications and improve risk stratification.
