Tragus
Definition:
(n.) The prominence in front of the external opening of the ear. See Illust. under Ear.
Example Sentences:
(1) This article analyses the advantages of the autogenous cartilage from the tragus split into multiple parallel pieces for the closure of big tympanic perforations and for the reconstruction of the middle ear after treatment of ventilation diseases like tympanic retraction or atelectasis.
(2) A simple technique to reconstruct the umbilicus is reported in which a conchal cartilage composite graft, such as that used in tragus construction in the treatment of microtia, was employed with a very satisfactory result.
(3) The anteroposterior inclination of the occlusal plane tends to affect the biting force, and the method with the ala-tragus line seems to be the most reasonable for occlusal plane orientation.
(4) It is composed of five critical elements: concha, helix, antihelix, tragus, and lobule, and parts of lesser importance including antitragus, intertragic notch, and Darwin's tubercle.
(5) On the 1st day following surgery, linear measurement (distance: tragus-pogonion) showed swelling to be 7.5% lower under drug treatment than in the placebo group.
(6) 3-CLT analysis was made on plane A (corresponding to P1 on a vertex-tragus channel), plane B (N1-P2) and plane C (P3.)
(7) Adequate positioning of the auricle and tragus has been achieved and a natural auricle obtained even when observed from a frontal oblique direction.
(8) Patients with compression fractures also had a greater degree of spinal deformity (distance from wall to tragus 24.5 cm v 12.7 cm in controls), less spinal mobility (20 v 45.6 degrees of flexion), and reduced chest expansion (2 cm v 3cm).
(9) Muscle activity during clenching at various given forces was least when the occlusal plane was made parallel to the ala-tragus line.
(10) This prosthesis is covered with a piece of autologous cartilage freshly removed from the tragus which forms the junction with the tympanic membrane or covering fascia.
(11) This interpretation supports the theory of Wood-Jones and I-Chuan according to which the tragus is formed from the material of the mandibular arch, and the remaining part of the auricle from the mesoderm of the second visceral arch.
(12) Six months later, tactile and tragus pinch pain thresholds had returned to normal; but thresholds for warmth, hot pain, and pinprick remained elevated.
(13) Morning pain and discomfort and wall-tragus distance were also significantly reduced by both drugs during the trial.
