Acoustic rhinometry of the Indian and Anglo-Saxon nose.

The internal and external geometry of the nose has previously been shown to differ between Anglo-Saxon, Chinese, and Negro noses. It is therefore important to define the normal geometric nasal parameters of a given race, so as to detect the abnormal nose. We present acoustic rhinometric data, with height-adjusted figures, examining the nasal minimum cross-sectional area (MCA), the distance to the nostril from the MCA, and the MCA between 0-6 cm. These data show no significant differences between Indian and Anglo-Saxon noses.
