A clinical study of thyroid surgery: A nine-year review of 365 patients at a single institution

Abstract

We examined 365 patients who underwent surgery for thyroid lesion at our institution during the nine years from July 2012 to September 2021. There were 112 benign lesions and 253 malignant tumors. The accurate diagnosis rate of fine-needle aspiration cytology （FNAC） was 91.7％. 76.4％ of Class 3 cases that received FNAC were malignant tumors. Postoperative recurrent laryngeal nerve palsy （RLNP） was observed in 20 case, of which 16 case were transient and 4 case were permanent. We examined the postoperative complications of RLNP regarding factors of age, gender, surgical side, histological type, the presence or absence of cervical lymph node dissection, and size. The frequency of RLNP increased in cases who were 55 years old and over, bilateral side, malignant tumor and cervical lymph node dissection.
