BACKGROUND The correct evaluation of the tracheal wall's structure is necessary for the management of postintubation tracheal stenosis (PTS). Endobronchial ultrasonography (EBUS) is suitable for visualisation of layers of the tracheal wall and the assessment of cartilages' damage. OBJECTIVE The authors assessed the usefulness of EBUS in the anatomical characterization of PTS and in the decision making in its therapy. METHODS Between March 2002, and September 2003, 22 patients with PTS were examined by bronchoscopy together with EBUS. RESULTS 13 patients had complex stenosis and from them destruction of tracheal cartilage was demonstrated in 5 patients. Of them bronchoscopic intervention resulted in only short term symptom free period in 3 patients. CONCLUSIONS The destruction of tracheal cartilage detected by EBUS might be an indication for an early surgical intervention. According to author's results EBUS can be a useful method in evaluation of PTS.

D001980	Bronchi	The larger air passages of the lungs arising from the terminal bifurcation of the TRACHEA. They include the largest two primary bronchi which branch out into secondary bronchi, and tertiary bronchi which extend into BRONCHIOLES and PULMONARY ALVEOLI.

D015203	Reproducibility of Results	The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.

D018615	Ultrasonography, Doppler, Color	Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.

D019160	Endosonography	Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.
