According to the concept of united airways, the respiratory system is a functional unit. Disorders affecting the upper segments of the respiratory tract may cause similar disorders of similar pathophysiology in the other parts of the tract [ 20 ]. Similar results obtained from all three anatomical locations give rise to the thought that oropharynx originated micro- organisms could be colonized to lower parts of the respiratory tract in integrity of upper airways. Larynx protective reflex mechanisms are known to be protective against oropharynx contamination [ 11 ]. However, positive pressure and forced inspiration applied during ICS administration could lead to contamination of the larynx by previously altered oropharyn- geal flora. In addition, unfavourable effects of ICS on laryngeal mucosa [ 14 ] could contribute to impairment of larynx protective mechanisms. As a result, laryngeal contamination could be facilitated by oropharyngeal secretions in ICS using patients. Conclusion Swabbing for detection of laryngeal colonization is a difficult procedure. However, airway tract should be considered as a single functional unit and in the case of oropharyngeal colonization detection; it should be kept in mind that colonization by similar micro-organisms is possible in the larynx. While clinicians plan treatment for oropharyngeal micro-organism colonization, they should keep in mind laryngeal colonization as well.
