The results of minimal access surgery in patients with benign tumors and lung bullae and also with mediastinal lymphadenopathy are presented. On the front and axial CT slices the possibility of accurate preoperative localization of mini-thoracotomy on intercostal space and conventional chest lines was demonstrated by simple calculations as well as the optimization of its length depending on the depth of the pathological focus. The developed method has allowed to reduce the length of the cut, to reduce the time of operation and the time of introduction of analgesics in the postoperative period
