| temporal branch of facial nerve | <anatomy, nerve> <anatomy, neurology> Branches of facial nerve innervating the superior portion of the orbicularis oculi muscle and other muscles of facial expression above the eye. Synonym: rami temporales nervi facialis. (05 Mar 2000) |
|---|---|
| tonsillar branch of the facial artery | <anatomy, artery> Primary blood supply to palatine tonsil, with extensive anastomoses with other tonsillar arteries. Synonym: ramus tonsillaris arteriae facialis. (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 asymmetry | Congenital or acquired asymmetry of the face. (12 Dec 1998) |
| 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. (12 Dec 1998) |
| facial canal | The bony passage in the temporal bone through which the facial nerve passes; the facial canal commences at the internal auditory meatus with the horizontal part which passes at first anteriorly (medial crus of facial canal) then turns posteriorly at the geniculum of the facial canal to pass medial to the tympanic cavity (lateral crus of facial canal); finally, it turns downward (descending part of facial canal) to reach the stylomastoid foramen. Synonym: canalis nervi facialis, aqueductus fallopii, fallopian aqueduct, fallopian canal. (05 Mar 2000) |
| facial cleft | A cleft resulting from incomplete merging or fusion of embryonic processes normally uniting in the formation of the face, e.g., cleft lip or cleft palate. Synonym: prosopoanoschisis. (05 Mar 2000) |
