Posture and nasal geometry.
The influence of posture on nasal cavity geometry was studied by acoustic rhinometry in 14 normal adult subjects. On adopting a supine position from sitting the volume of the initially more patulous nasal cavity decreased and the volume of the less patulous side increased. These changes in volume are statistically significant (p = less than 0.01).
