Abstract

Nasal inspiration is important for maintaining the internal milieu of the lung, since ambient air is conditioned to nearly alveolar conditions (body temperature and fully saturated with water vapor) on reaching the nasopharynx. Recently, pharmaceutical and surgical interventions are used at an increasing rate to restore both nasal structure and function. In this study, we examined the impact of surgical interventions on the overall capacity of the nasal cavity to condition inspired air to near alveolar conditions.
