Thyroid surgical procedures have seen great evolution since the mid-nineteenth century, with mortality rates dropping, just as surgical techniques have developed. However, on the other hand, bleeding in the postoperative period, hypoparathyroidism, and recurrent laryngeal nerve paralysis are still significant complications of concern. This retrospective meta-analysis aims at synthesizing the trends and outcomes of thyroid surgery in Iraq, focusing on surgical innovations, complication rates, and evolving clinical guidelines as the third factor. A systematic search of major academic search engines and Google Scholar identified retrospective and systematic review studies on trends and outcomes in thyroid surgery in addition to surgical techniques, complication rates, demographic trends, and the impact of clinical guidelines where Data extracted independently by two reviewers were synthesized using standardized tables where quantitative syntheses were made when possible. Heterogeneity was assessed to ensure that pooled estimates were robust. Analysis of high-quality studies demonstrated the clear drift toward minimally invasive and robotic thyroidectomy with lesser postoperative morbidity and improved cosmetic outcomes compared to traditional open surgery. Outpatient thyroidectomy is becoming increasingly practiced, with evidence supporting low complication rates in appropriately selected patients. Updated clinical guidelines, particularly those from the American Thyroid Association, have resulted in a more conservative approach to surgery and a decrease in unnecessary completion thyroidectomies in this meta-analysis.
Nevertheless, hypoparathyroidism remains the most common complication, while recurrent laryngeal nerve injury diminishes the patient's quality of life. Institutional volume, surgeon experience, and access to advanced technology play a significant role in determining complication rates and outcomes. Finally, thyroid surgery in Iraq follows global trends toward minimally invasive procedures, outpatient care, and evidence-based practice. Emphasis on surgeon training, individualized patient care, and guideline refinement must continue in order to bring down complications and improve outcomes.
