Surgical Outcomes of Thyroidectomy in Geriatric Patients Aged 80 Years and Older: A Single-Center Retrospective Cohort Study

<i>Background and Objectives</i>: As the global aging population grows, the incidence of thyroidectomy in elderly patients is increasing. This study aimed to evaluate the surgical outcomes of thyroidectomy in patients aged 80 years and older. <i>Materials and Methods</i>: All patients aged 80 years and older who underwent thyroidectomies at our hospital between January 2015 and December 2022 were reviewed in this retrospective cohort study. Collected data consisted of patients' clinical characteristics, functional status, compression symptoms, preoperative assessments, perioperative outcomes, postoperative complications (such as bleeding events, recurrent laryngeal nerve injury, hypocalcemia), pathological findings, readmission, and follow-up outcomes. <i>Results</i>: Seventeen patients were included in this study, with female predominance (82.4%). The mean age was 85.6 ± 4.8 years. Fourteen patients (82.4%) exhibited compression-related symptoms as surgical indications. Based on pathological reports, patients were categorized into benign (12/17, 70.6%) and malignancy (5/17, 29.4%) groups. The benign group had a shorter operation time compared with the malignancy group (164.3 ± 32.0 min vs. 231.0 ± 79.1 min, <i>p</i> = 0.048). No major postoperative complications developed. The median postoperative follow-up duration was 28 months (range: 2-91 months). Thirteen patients (76.5%) were alive at the end of the study period. <i>Conclusions</i>: Despite potential age-related risks, thyroidectomy is feasible for carefully selected patients aged 80 years and older. It provides benefits not only in terms of oncological curative treatment but also in improving the quality of life, such as compressive symptoms and wound condition.
