摘要
在３８侧双人尸体标本上观察，颞浅动脉在耳屏切迹以上位于颧垂线前，耳后动脉恒定经耳廓后沟上升。动脉沿途发２～４支耳支，分别滋养耳廓处侧面和背面，并相互吻合。神经血管伴行。经临床应用１２例和尸体摹拟手术实验表明，联合切口术野充分，适宜各种中耳乳突手术．血管神经及其耳支均能保留于下１／４蒂内，从而保证了术后的耳廓血供。对切口设计和术中注意事项进行了讨论。
he blood supply to the auricle was observed on 38
sides of adult cadavers.The superficialtemporal artery lies anterior
to the zygomatic ventricle line above the tragus notch and has
divi-sions to the lateral side of the auricle.The posterior auricular
artery ascends along the posteriorsulcus of auricle constantly and
divides to the posterior side of the auricle,The divisions
accompa-nied with nerve branches anastomeses on the upper margin of
the auricle. Imitative operation oncadavers showed that combined
auricular incision could offer a large operation field.
Satisfactoryresults have been gained in 12 cases of patients with
operations in the middle ear and mastiod re-gions.Key points in the
design and application of combined auricular incision were also
presented.
