Pattern of the temporal branch of the facial nerve in the upper orbicularis oculi muscle.

摘要: The purpose of this study is to clarify a pattern the temporal branch facial nerve in upper orbicularis oculi muscle (OOM) and an impact exploiting frontalis myofascial advancement flap. authors investigated OOM 20 cadavers. highest lowest level coursing into were measured at three different sagittal/vertical planes through lateral canthus, midpalpebral fissure, medial respectively. designate hazard zone that delineates circle with 1.0-cm diameter its center located inferiorly laterally direction -15 degrees 7.5 cm from canthus. those twigs entered on X-axis Y-axis origin canthus +2.51 +/- 0.23 cm, +2.70 0.35 0 +2.68 0.32 mid-palpebral +3.47 0.27 +3.49 0.45 +2.97 +1.62 0.12 +1.82 0.17 +1.63 0.22 Those coursed horizontally along fibers interconnections but did not cross over superior orbital rim. describe details zone, wherein should be spared. They also assure injury inevitable procedure
