JOURNAL TITLE: An International Journal of Otorhinolaryngology Clinics
Aim and objective: The study aimed to evaluate the incidence and associated risk factors for the development of hypothyroidism in patients who underwent lobectomy for colloid goiter. Materials and methods: The study included 50 patients, out of which postoperative hypothyroidism was observed in 18 patients, with an overall incidence of 36%. Hypothyroidism was diagnosed in 90% of patients within 9 months after the surgery. The preoperative TSH levels were directly proportional to the postoperative TSH levels and were confirmed as independent risk factors for the development of hypothyroidism. Discussion and conclusion: The incidence of postoperative hypothyroidism after lobectomy is quite significant and cannot be ignored. Elevated preoperative TSH levels are associated with an increased risk. A long follow-up period is required to find the true incidence of postoperative hypothyroidism and identify those having subclinical hypothyroidism.
