Sputum crust formation in patients receiving tracheostomies. Case 1 (A1-4). A 70-year-old male patient, 5 years after a total laryngectomy, was admitted with dyspnea for 2 days. The oropharyngeal and tracheal swabs were positive for SARS-CoV-2. After admission to the hospital, the patient underwent computed tomography (CT) scan of the lung and laryngoscope examination. A1: Dense shadow (indicated by black arrow) in the trachea as indicated by CT. A2: Dense shadow (indicated by black arrow) in the bronchus as indicated by CT. A3: Endoscopic manifestation of brown sputum crusts formation in the trachea causing airway obstruction. A4: Massive sputum crusts were removed from the airway by emergency surgery. Case 2 (B1-2). A 70-year-old male patient, 10 years after a total laryngectomy, was admitted with dyspnea for 3 days. B1-2: Dense shadow (indicated by black arrow) in the trachea as indicated by CT
