BACKGROUND: Myasthenia gravis is an autoimmune disease with high prevalence of thymus disorders, in which, thymectomy is considered one of the therapeutic approaches in improving the patients' clinical outcomes. Today, thoracoscopic thymectomy has received significant attention than the classic transsternal approach due to fewer complication. Therefore, this study was designed with the aim of investigating the therapeutic outcomes of thymectomy in patients with myasthenia gravis in the Afzalipour Hospital of Kerman between 2011 and 2021. METHODS: The current study is a descriptive analytical study on patients with myasthenia gravis who underwent surgical thymectomy within 2011-2021. Demographic and clinical characteristics of patients from the time of operation to three years of follow-up were extracted and recorded from clinical records or by phone calls. Data were analyzed using SPSS software. RESULTS: The data of 70 patients who underwent surgical thymectomy were analyzed. Thymectomy caused a significant reduction in the severity of the disease according to the Osserman classification (P = 0.001). It also significantly reduced the use of corticosteroids (P = 0.001) and IVIG (P = 0.015) compared to the time before the surgery. Sixty-two patients (88.57%) needed to take less medicine than before surgery. Left VATS was associated with less post-operative severity of the disease (P = 0.023). There were only two deaths during the follow-up period. CONCLUSION: Overall, the findings of the present study demonstrated that thoracoscopic thymectomy is a useful surgical approach that leads to faster recovery, reducing the severity of the disease, need for medication, and complications in patients with myasthenia gravis, In comparison with the transsternal approach.
