Objectives: Thyroidectomy for advanced laryngeal squamous cell carcinoma (LSCC) is controversial. This study aimed to identify predictors of thyroid gland invasion in patients with LSCC and management of the thyroid gland during total laryngectomy. Patients and Methods: Clinical data and pathological characteristics of 113 patients, who underwent laryngectomy with thyroidectomy for advanced LSCC in Guangdong Provincial People's Hospital between 2009 and 2019, were retrospectively analyzed. The incidence and predictors of thyroid gland invasion were analyzed, and a new predictor was proposed using a parallel test. Results: Of 113 patients, 25.7% exhibited thyroid invasion. A new predictor that combined the lower third of thyroid cartilage invasion and thyroid gland invasion on computed tomography/magnetic resonance imaging (CT/MRI) was associated with pathological thyroid gland invasion ( P = 0.001; sensitivity, 88.2%; negative predictive value, 95%). Conclusion: Thyroidectomy may be required during total laryngectomy in those with invasion of the lower third of thyroid cartilage and/or thyroid gland invasion revealed on CT/MRI instead of being performed routinely.
