It can be performed as a blind procedure during conventional white light bronchoscopy (bronchoscopic- TBNA) or under image guidance using Endobronchial ultrasound (EBUS-TBNA).
Furthermore, conventional TBNA and EBUS-TBNA have comparable diagnostic accuracy in puncture sampling of mediastinum 4R, subcarinal group, and large lymph nodes (17,18).

Once the target lymph node was identified, the probe was then removed from the working channel, and the needle was placed through the sheath and remained in place in order to stabilize the lesion during the TBNA [7,13].
Training in EBUS-TBNA is a detailed process containing a comprehensive information on "bronchocentric" mediastinal anatomy, ultrasound physics, competency in handling EBUS for examination of peribronchial structures, interpretation of ultrasound images, and performing TBNA with the dedicated needle.
