Background: Thyroidectomy is one of the safest operations performed for patients with thyroid diseases, but at times complications such as recurrent laryngeal nerve injury with airway obstruction, hypocalcemia, cervical hematoma and surgical site infection can arise following thyroidectomy. Even though some of these complications are minor, others are grave and have significantly affected the quality of life of patients and some others have endangered the lives of patients. As to my knowledge, there is limited study done in this city on prevalence of complications after thyroidectomy. OBJECTIVE: The objective of this study is to determine the prevalence of overall complications after thyroidectomy at government referral hospitals in Bahirdar city. Methods: Facility based retrospective cross sectional study was conducted on 163 patients operated for thyroid disease between January 1, 2018 and December 31, 2019 in government referral hospitals in Bahirdar city. Structured check list was used to retrieve information from medical records. Data was cleaned, coded and entered to SPSS 20 for analysis. Result: In this study 163 patients who underwent surgery for thyroid diseases were included. The majority of the patients were in the third and fourth decades of their life and most live outside Bahir Dar city. The most common chief compliant was anterior neck swelling and the most common operation was subtotal thyroidectomy followed by dunhills procedure. Eighteen patients(11%) have developed complications and the commonest complication was voice change(6.1%). Conclusion and recommendation: Overall prevalence of complication after thyroidectomy was lower than most international studies but the prevalence of voice change was higher than other studies, so intraperative identification and preservation should be encouraged to reduce this complication.
