Does only thymectomy influence on results of surgical treatment at patients with myasthenia gravis?

Methods We have analyzed results of surgical treatment of 87 patients having myasthenia gravis. There were 68 (79,2%) female, 19 (21,8%) male. Patients ranged in age from 15 to 64 years. 80 patients (91,9%) had generalized myasthenia, 7 patients (8,1%) had local forms of myasthenia. The most number of patients had IIb – Iva degree of myasthenia according to international clinical classification. All patients underwent extended thymectomy. At 75 patients we have performed thymectomy by median sternotomy, at 10 patients – by VATS. Dissection of mediastinal fat was a mandatory component of operation. The histologic pattern was: thymoma – at 43 patients (49,4%), thymic hyperplasia – at 42 patient (48,3%), thymic atrophy – at 2 patients (2,3%). Additional thymus corpuscles were revealed at 10 patients (11,5%).
