Background: In thyroid nodular pathology, intraoperative histological examination is a crucial diagnostic tool that helps guide surgical decision-making.
Objectives: To assess the accuracy and effectiveness of intraoperative histological examination in the management of thyroid nodules and to highlight its benefits and limitations as a real-time diagnostic tool during surgery.
Methods: This retrospective cross-sectional study analyzed 333 intraoperative histological examinations performed on thyroidectomy specimens at our ENT Department over a five-year period (January 2018 December 2022).
Results: I this study the mean age of 47.45 years, with a strong female predominance (male-to-female ratio of 1:5.8). The most common reason for discovery was a palpable cervical mass (57.35%), while incidental detection via ultrasound accounted for 15.6%. Ultrasound findings revealed that multinodular goiters were more prevalent (61.6%) than solitary nodules (38.4%). Malignant tumors were diagnosed in 21.3% of cases, with the majority being papillary carcinoma (87.3%), followed by follicular carcinoma (9.8%), medullary carcinoma (1.4%), and anaplastic carcinoma (1.4%). Intraoperative examination identified 61 malignant cases, 259 benign cases, and 13 uncertain cases. When compared to the final histopathological examination across all histological types, intraoperative examination demonstrated a diagnostic accuracy of 93%, with a sensitivity of 85.9%, specificity of 100%, positive predictive value (PPV) of 100%, and negative predictive value (NPV) of 96%. The Youden index was 0.86. The sensitivity of intraoperative examination varied by histological type. It showed strong concordance with the final pathology report in 90.3% of papillary carcinomas and 100% of medullary and anaplastic carcinomas, but only 42.8% of follicular carcinoma cases. The rate of secondary surgical interventions following final histological examination was 3% (10 cases).
Conclusion: Intraoperative histological examination plays a pivotal role in the surgical management of thyroid nodules, offering rapid and precise diagnosis that optimizes surgical decision-making and minimizes the need for reoperations. Its high specificity and sensitivity enhance patient care by ensuring appropriate surgical intervention.
