Objective:To explore the clinical paticularities and experiences in diagnosis and treatment of elderly patients with thyroid nodules. Methods:The clinical records of 144 patients more than 60 years old and 1412 young or middle-aged patients less than 60 years old with thyroid nodules admitted to Ruijin hospital were retrospectively analyzed. Results:Compared with the young or middle-aged patients, the elderly patients with thyroid nodules presented the following particularities: bilateral and multifocal lesions were the main manifestations and usually with larger nodules in diameters; compression symptoms and secondary hyperthyroidism were the main surgical indications; the reoperation rate was higher due to recurrence; the preoperative ASA score was poor; near-total thyroidectomy for bilateral and multifocal nodules under gereral anaesthesia was the main procedure; fat depositions were frequently found around the recurrent laryngeal and parathyroid glands during surgery, and the calcification rate of benign nodules was high (P>0.05). Except for higher incidence of transient hypocalcemia in the elderly patients, no significant difference was noted in terms of postoperative complication between the clderly and younger patients. Conclusions:In elderly patients with thyroid nodules, the surgical risks or complications can be reduced or avioded as long as their clincal particularities are fully understand and proper treatment is employed.
