| descending part of facial canal | Second portion of the facial canal, after the horizontal parts, beginning at the posterior end of the lateral crus where the canal begins to descend. It runs vertically downward, ending at the stylomastoid foramen. Anteriorly, the descending part of the facial canal communicates with the tympanic cavity via the canaliculus for the nerve to the stapedius muscle and the posterior canaliculus of the chorda tympani.

| introitus of facial canal | Entrance to facial canal, through which the facial nerve passes, at end of internal acoustic meatus. Synonym: introitus canalis. (05 Mar 2000) |
| oblique facial cleft | Congenital facial cleft from mouth to the inner canthus of the eye. Synonym: oblique facial cleft. Origin: prosopo-+ G. Schisis, fissure (05 Mar 2000) |
| Topinard's facial angle | See: Jacquart's facial angle. (05 Mar 2000) |
| total facial index | Length is measured from the nasion to the mental tubercle: (nasimental length × 100)/bizygomatic width. (05 Mar 2000) |
| transverse facial artery | <anatomy, artery> Origin, superficial temporal; distribution, parotid gland, parotid duct, masseter muscle, and overlying skin; anastomoses, infraorbital and buccal branches of maxillary, and buccal and masseteric branches of facial. Synonym: arteria transversa faciei. (05 Mar 2000) |
| transverse facial fracture | A complex fracture in which the facial bones are separated from the cranial bones. Synonym: Le Fort III craniofacial dysjunction, Le Fort III fracture, transverse facial fracture. (05 Mar 2000) |
| transverse facial vein | <anatomy, vein> A tributary of the superficial temporal or retromandibular veins, anastomosing with the facial vein. Synonym: vena transversa faciei, transverse vein of face. (05 Mar 2000) |
| Jacquart's facial angle | A facial angle with the intersection always at the nasal spine point; additional variation uses the supraorbital point instead of the glabella, and this latter version is also known as ophryospinal facial angle or Topinard's facial angle. (05 Mar 2000) |
| facial | Origin: L. Facialis from facies = face of or pertaining to the face. (18 Nov 1997) |
| facial angle | Any of several variously named and variously defined anatomical angle's that have been used to quantify facial protrusion, in dentistry, the angle formed by the intersection of the orbitomeatal (Frankfort) plane with the nasion-pogonion line (inner lower angle), which establishes the anteroposterior relation of the mandible to the upper face at the orbitomeatal plane. Synonym: Frankfort-mandibular incisor angle. (05 Mar 2000) |
| facial artery | <anatomy, artery> Origin, external carotid; branches, ascending palatine, tonsillar and glandular branches, submental, inferior labial, superior labial, masseteric, buccal, lateral nasal branches, and angular. Synonym: arteria facialis, arteria maxillaris externa, external maxillary artery. (05 Mar 2000) |

| facial axis | A line drawn from the subnasal point to the midpoint of the sphenoethmoidal suture. Synonym: facial axis. (05 Mar 2000) |
| facial bones | The facial skeleton, consisting of bones situated between the cranial base and the mandibular region. While some consider the facial bones to comprise the hyoid, palatine, and zygomatic bones, mandible, and maxilla, others include also the lacrimal and nasal bones, inferior nasal concha, and vomer but exclude the hyoid bone.
