(2008) and Ishiyama (1958), were taken: 1) total length (TL); 2) disc length; 3) disc width; 4) tail length; 5) head length; 6) dorsal snout length; 7) eye diameter; 8) distance between orbits; 9) ventral head length; 10) ventral snout length; 11) prenasal
snout length; 12) distance between nostrils; and 13) distance between 1st gill openings.
We judged the therapeutic effect of nasal surgery by PSG, which showed an AHI of <10 or a decrease of 50% in AHI of postnasal surgery when compared with AHI changes of prenasal
spasma) by a longer forearm short and broad tragus deep prenasal
notch and smaller post- orbital process (Csorba and Topal 1994).
They all arise from a lack of regression of a dural diverticulum in the prenasal
space that extends through the embryologic foramen cecum or the fonticulus frontalis.
Our enthusiasm about things like screening for Down syndrome with sophisticated techniques such as nuchal translucency, nasal bone measurement and tricuspid incompetence, as well as the new additions like prenasal
thickness measurement, must therefore be tempered by the knowledge that the majority of women do not even have a dating scan.
Nostril narrowly oval to slit-like, directed longitudinally to slightly oblique; anterior margin fleshy; anterior nasal fold internal, very narrow, membranous; broad oronasal groove present; internarial space 1.21 (1.24) in prenasal
length, 1.98 (1.97) times nostril length.

The underlying form of the second stem in each two stem sequence does not have an initial nasal component because there is no contrast in this context between stems beginning with a voiced stop or affricate and ones beginning with a prenasal
