The authors' experience of surgical treatment of myasthenia gravis in children was analyzed. 32 patients were operated on, mean age was 13±3 (5-21 years); girls were 26, boys were 6 (19%). Disease severity was IIB-IVB by the MGFA classification, all patients were on anticholinesterase and pednisolone therapy. The operation was indicated by certified neurologists, specialized in myasthenia. All patient were thoracoscopically thymectomized using left- or rightside access. There were no conversions and intraoperative complications. The operation duration was 77±23 min. The postoperative hospital stay was 6.6±3.6 (3-9) days. Excellent long-term results were achieved in 6 (25%) patients, good - in 20 (62.5%) children, no changes were registered in 2 and deterioration of myasthenia in 2 (6.25%) patients. The study proved that thoracoscopic thymectomy obtains the radicalism of open technique, proposing the easier postoperative period and being the method of choice for the surgical treatment of myasthenia gravis in children.
