[Treatment of nasal obstruction]

Various methods of treatment of impaired nasal patency are presented calling attention to the fact that the most frequent cause of impairment of nasal respiration is deviation of the nasal septum associated with unilateral or bilateral hypertrophy of inferior turbinates. Impaired nasal breathing leads to frequent recurrences of respiratory infections. Restoration of normal breathing route and physiological role of the nase, among others, warming and moistening of inspired air, is an important and ever present problem in laryngology. The problem has assumed a new importance when it was found that chronic impairment of nasal patency could have an adverse effect on the circulatory system which develops in connection with sleep apnoea.
