Abstract
During the past decade there have been many developments relative to local treatment for infection of the upper part of the respiratory tract. There are two which I wish to discuss. One is the use of head-low posture for making the nasosinal area available for treatment. The other is the use of drugs and vehicles compatible with nasal physiology. The use of headlow posture implies recognition of the intricate and varied anatomy of the nasosinal area. The use of physiologic solutions implies realization of the function of the nasal mucous membrane. The two developments are to a great extent interdependent. Without a physiologic solution the posture would be ineffective or of limited use. Without head-low posture it is doubtful whether the need of physiologic solutions would be so easily recognized and accepted. To Dr. Arthur Proetz1more than to any other person physicians owe recognition for initiating these changes.
