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.
