A study of nasolacrimal canal in crania from Uttar Pradesh (India).
The length of the nasolacrimal canal and the diameter of its superior aperture were measured in 200 adult skulls from Uttar Pradesh (India). The mean length of the right and left canals were 2.15 cm and 2.39 cm, respectively. The antero-posterior diameter of the superior aperture is more than that of the transverse diameter in both the sides. The right canal has got a larger transverse diameter. But its antero-posterior diameter is less than that of the left side. The correlations between the various measurements were calculated. A positive correlation between the canal length and the nose length has been observed.
