Clinical features
The distinction of cause of admission and physical examination findings according to the type of malacia is shown in Table 3 . The most common complaint during admission to our clinic was recurrent and/or prolonged respiratory infection (46.2%) and the most common physical examination finding was stridor (36.9%). A patient with immunodeficiency, who was performed bronchoscopy for microbiological sampling, due to a short-time lower respiratory tract infection, was diagnosed malacia incidentally.
