Objectives: In patients who had undergone thyroidectomy in Japan for benign tumor, we determined whether thyroid lobe size correlates with temporary recurrent laryngeal nerve paralysis (T‐RLNP). Methods: We retrospectively collected medical record data on usage of intraoperative neuromonitoring, laterality of thyroidectomy, amount of bleeding during surgery, duration of surgery, and whether the surgeon was a board certified otorhinolaryngologist as determined by the Oto‐Rhino‐Laryngological Society of Japan. Thyroid size was measured in preoperative axial computed tomography (CT) images. Receiver operating characteristic (ROC) curve analysis was used to determine the thyroid size that predicted a high risk of T‐RLNP or permanent recurrent laryngeal nerve paralysis (P‐RLNP). Results: Of the 146 eligible patients identified, 9 (6.2%) developed T‐RLNP and 2 (1.4%) developed P‐RLNP. The amount of bleeding during thyroidectomy was significantly greater in T‐RLNP patients than in P‐RLNP patients. Thyroid sizes in CT images were significantly larger in T‐RLNP patients compared to patients who did not develop RLNP (referred to hereafter as N‐RLNP). ROC analysis revealed that 1.3% of thyroid lobes with an area of less than 1000.0 mm2, and 9.9% of thyroid lobes with an area of greater than 1000.0 mm2 were at risk for T‐RLNP. Conclusion: We presented evidence that thyroid sizes, as measured on preoperative axial CT images, were larger in T‐RLNP patients than in N‐RLNP patients. Our results indicate a connection between benign thyroid tumor stretch injuries and T‐RLNP. Level of Evidence: IV. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 12-year-old girl presented with a 5-day history of headache, 3-day history of fever, and 1-day history of neck pain on the right side. The article discusses that she had neither enlarged cervical lymph nodes nor nuchal rigidity; and she complained of neck pain on the right side and of restricted movement in her neck due to the pain.
