1) In-depth is the prevertebral fascia.

2) Objective:To investigate the anatomic relationship between prevertebral fascia and carotid sheath and to guarantee the safety of the common carotid artery in anterior cervical approach.

3) Multiple variation exists in the prevertebral segments of vertebral arteries, the left vertebral artery is more dominant than the right one.

4) The mucosa and prevertebral muscles are elevated as a single mucoperiosteal layer using subperiosteal dissection, and are retracted laterally.

5) The deep layer of the deep cervical fascia was subdivided into alar fascia and prevertebral fascia.

6) Method:the origin, appearance, course, and original outer diameter of the prevertebral part for vertebral artery were investigated on 114 adult cadavers.

7) Objective To study the mechanism and difference of fractured vertebral body' s prevertebral height recovery following different methods of reduction.

8) Results: Anastomotic leakage occurred more frequently in retrosternal group than in prevertebral group(22.5% vs. 8.6%).

9) Result of autopsy indicated:sympathic trunk directly divides branches into prevertebral fascia and anterior longitudinal ligament.

10) Conclusion The sign of asymmetrical narrowing or disappearing of NRS highly suggests the involvement of prevertebral muscle.

11) Posterior pharyngeal carcinoma (14 cases) usually invaded pyriform sinus (100%), aryepiglottic fold (92.9%), postcricoid region (71.4%),[http:///prevertebral.html] prevertebral fascia (71.4%) and esophagus (64.3%).

12) To evaluate the short-term quality of life(QOL) in patients with retrosternal or prevertebral gastric tube reconstruction after three-incision esophagectomy.
