Mediastinoscopy is a surgical procedure utilized for the evaluation of mediastinal lesions, particularly in patients suspected of having bronchogenic carcinoma. This procedure involves making a small incision above the suprasternal notch, which is located between the borders of the sternocleidomastoid muscle. The incision is carefully extended down to the pretracheal fascia, which is then divided to allow access to the mediastinum. A mediastinoscope, a specialized instrument, is inserted behind the suprasternal notch and advanced behind the aortic arch into the superior mediastinum. This allows for a thorough examination of the mediastinum, including the carina and the main bronchi, for any lesions, tumors, diseased tissue, or other abnormalities. During the procedure, biopsies of any identified masses or lesions, such as lymphoma, may be performed through the endoscope as necessary. The procedure concludes with the withdrawal of the mediastinoscope and the closure of the incisions. This technique is essential for obtaining tissue samples for diagnosis and for assessing treatment options for various mediastinal conditions.
