The main value of the procedure is to reduce the number of unnecessary thoracotomies in patients with intrathoracic lesions. Reynders² in 1964 reported a positive rate of 36.9%. He found that previous to routine use of mediastinoscopy, there was a 40% nonresectable rate of carcinoma of the lung. With negative mediastinoscopy, the resectable rate was increased to 91%.

Mediastinal lymph nodes are almost always involved with granulomas in sarcoidosis. Thus, one can easily make a diagnosis of sarcoidosis through mediastinoscopy according to MacVaugh and Danielson³ in almost 100% of patients with sarcoidosis.

Technique Mediastinoscopy is best done under endotracheal general anesthesia. The patient is placed
