Comparison of Tracheal Laryngoscopic Images Before and After Different Scraping Methods. (a) Normal Tracheal Mucosa. (b) Tracheal Mucosa After Nylon Brush Scraping: The mucosa exhibits congestion and swelling but remains intact. (c) Tracheal Wall After Steel Brush Scraping: Image revealing the complete detachment of the tracheal mucosa after ten scrapings with the steel brush. The tracheal cartilage is clearly visible.
