Abstract: In thoracoscopy, there is a requirement for provision of adequate space to identify the anatomy and instrumentation for dissection. To obtain space lung is collapsed and the collapsed lung has to be retracted away from the field of dissection. This could be done with retractors which will need additional ports and assistants. Some of the procedures are traditionally being done as lateral decubitus position. We have used supine or prone positioning for the lung to fall away from the surgical field. Supine position for anterior and superior mediastinal procedures and prone position for posterior medistinal procedures were used. The use of gravity to retract lung by positioning provided space, which is a major requirement for the success and safety of the surgery. There were no derangements observed in the physiological stability in supine or prone positions.
