On MRI, nasal dermal sinus tracts will present as T1hypointense linear tract extending from the foramen cecum through the subcutaneous soft tissues of the midline nasal bridge to the prenasal space.
Six morphometric characters were studied, five in the triangular region (tr) that articulates with the nasal, premaxillae, prenasal, and vomer: length of the triangle (ML), height of the triangle (MH), width from the lateral surface of the triangle to the medial margin of the facet (fv) for articulation with the vomer (MW), and height (MVH) and width (MVW) of the facet.
The left prenasal (pn) is complete, except for a middle segment, and the right pn is poorly preserved, except for its most distal extension onto the rostrum.
Characters studied without reference to region were: distribution of denticles on the dorsal surface of the rostrum measured from the distal tip (DZ); length from distal tip where denticles are absent from the ventral mid-line (DVS); length from the distal tip to the distal extremity of t he prenasal (P); length from tip where fused premaxillae divide into separate bones (VSPM); and presence or absence of denticles on the prenasal.
The maxillary segment contains its anterior articulation with the prenasal, dorsal articulation with the lacrimal, and ventral articulation with the premaxilla.
The neurocranium contains the anterior-most part of the frontals, lateral ethmoids, nasals, and posterior parts of the prenasals.
m]f] with a constraint I refer to here and below as PRENASAL in (8).
PRENASAL is also intended to account for the rarity of prenasalized laterals and prenasalized trills in the languages of the world.
m]faha] follows from the fact that PRENASAL outranks MAX-C.
In (13) we established that MAX-C outranks UNIFORMITY and in (19) that SSG, LINEARITY, and PRENASAL outrank MAX-C.
