Study on applied anatomy of temporalis / 重庆医学

ABSTRACT

Objective To investigate the architectural features of temporalis and offer anatomic basis for the clinical application . Methods In eight cadavers ,the gross anatomy ,muscular architecture study of temporalis were performed on anterior ,middle and posterior portion .Results The wet muscle weight of the above portions was (13 .17 ± 3 .41) ,(12 .30 ± 3 .59) ,(9 .68 ± 2 .50)g ;their muscle length was (91 .28 ± 5 .93) ,(100 .15 ± 3 .64) ,(110 .53 ± 6 .18)mm ;and their physiological cross-sectional area in muscle was (485 .90 ± 124 .36) ,(396 .59 ± 110 .05) ,(313 .31 ± 75 .72)mm2 ,respectively .Conclusion These results indicated that the anterior portion of temporalis muscle is designed for tension production ,but the posterior and middle for velocity production .Posterior and middle portion of temporalis muscle could quantifying transfer for the dynamic correction of facial paralysis according to the physio-logical cross-sectional area .
