This table originates from the article Acromelic frontonasal dysplasia : further delineation of a subtype with brain malformations and polydactyly ( Toriello syndrome )', Verloes et al.
12.
By the upgrowth of the surrounding parts these areas are converted into pits, the olfactory pits, which indent the frontonasal prominence and divide it into a medial and two lateral nasal processes.
13.
Furthermore, disorders like an intracranial cyst can affect the frontonasal region, which can lead to symptoms similar to FND . Therefore, other options should always be considered in the differential diagnosis.
14.
When the anterior end of the uncinate process fuses with the front part of the bulla, however, this continuity is interrupted and the frontonasal duct then drains directly into the anterior end of the middle meatus.
15.
It consists of a thin infundibulum, extends upward and forward through the labyrinth and communicates with the anterior ethmoidal cells, and in about 50 % of skulls is continued upward as the frontonasal duct into the frontal sinus.

Some of the lizards in this genus contains specific features such as : rostral and frontonasal scales; one postanal scale; supranasal and anterior loreal scales; 36 or less macro chromosomes; egg-laid embryos somewhat developed.
17.
All mice that were homozygous for the DKK1 knockout were dead at birth due to defects in the cranium and structures formed by the neural crest, such as failed development of eyes, olfactory placodes, frontonasal mass and mandibular processes, as well as incomplete development of the forebrain and midbrain and fusion of the digits of the forelimb.
18.
Through the hiatus semilunaris the meatus communicates with a curved passage termed the infundibulum, which communicates in front with the anterior ethmoidal cells and in rather more than fifty percent of skulls is continued upward as the frontonasal duct into the frontal air-sinus; when this continuity fails, the frontonasal duct opens directly into the anterior part of the meatus.
