Question

Quizplus · Accepted Answer

Mediastinoscopy has long been considered the gold standard for the staging of mediastinal lymph nodes because it allows for direct examination and possible biopsy of the lymph nodes. A flexible fiberoptic bronchoscopy may be used for visualization of the airways but does not offer direct access to the lymph nodes. Direct laryngoscopy is used for visualization of the larynx and does not provide access to the mediastinum. Pleurocentesis is used to obtain fluid from the pleural space and does not provide access to the mediastinum or lymph nodes.
