thoracotomy

Full Definition

A thoracotomy is a surgical procedure involving an incision through the chest wall to provide access to the lungs, heart, esophagus, or other thoracic structures. Unlike a sternotomy, which divides the sternum, a thoracotomy typically involves cutting through the intercostal muscles between the ribs. Common approaches include posterolateral, anterolateral, and lateral thoracotomies, each providing different exposure depending on the surgical target.

Usage

Usage note: Specify the approach (posterolateral, anterolateral) when documenting the procedure.
