mediastinoscopy

Full Definition

Mediastinoscopy is a diagnostic procedure that uses a mediastinoscope inserted through a small incision above the sternum to visualize and sample lymph nodes in the mediastinum. This technique is commonly used for staging lung cancer, diagnosing mediastinal masses, and evaluating lymphadenopathy. The procedure allows direct visualization of paratracheal and subcarinal lymph nodes while avoiding more invasive surgical approaches.

Usage

Usage note: Specify approach (cervical vs. extended) when documenting the procedure.
