orbitonasal or·bi·to·na·sal (ôr'bĭ-tō-nā'zəl)
Relating to the orbit and the nose or nasal cavity.
Relative to basilar length, tooth-rows, orbitonasal length, interorbital breadth and zygomatic breadth averaging narrower.
At the level of the orbitonasal foramen, the sphenethmoid is entirely ossified except for a small dorsolateral extension.
The relatively long rostrum, as represented by the orbitonasal length, is nearest to that of spadix.
The skull is similarly proportioned except that relative to the basilar length the orbitonasal length is more.
