颧骨缩小整复术相关骨性解剖学观测

Observation on correlative osteal anatomy in zygomatic reduction diorthosis

目的:为颧骨缩小整复术提供解剖学基础。方法:对30例成年女性颅骨标本的颧骨结构进行观测。结果:①颧突位于颧骨的中下1/3交界处;②颧突点处颧骨的厚度,左侧:(6.68±1.64)mm;右侧:(6.77±1.43)mm,左右两侧无显著性差异(P>0.05);③眶下孔距同侧眶下缘和颅正中线的距离分别为左侧:(8.33±1.48)mm、(25.01±1.32)mm;右侧:(7.77±1.56)mm、(25.20±1.07)mm;左右两侧均无显著性差异(P>0.05);④颧骨额突至上颌窦外上角的距离和上颌窦前壁的厚度分别为左侧:(42.57±5.8)mm、(0.50±0.03)mm;右侧:(43.02±6.4)mm、(0.49±0.05)mm;左右两侧均无显著性差异(P﹥0.05)。结论:颧骨结构的细致观测对更好的开展颧骨缩小术减少其并发症具有重要意义。

Objective Provide anatomic base for zygomatic reduction diorthosis.Methods The zygomatic structures of 30 adult female cranial specimens have been observed.Results ①Zygomatic process is situated at the 1/3 juncture of the zygomatic lower middle section.②The zygomatic thickness at the location of the zygomatic process point: It's(6.68±1.64)mm on the left side and(6.77±1.43)mm on the right side respectively: The thickness is free from significant difference between the left and the right(P﹥0.05).③The distance of the infraorbital foramen to the ipsilateral infraorbital margin is(8.33±1.48)mm on the left side and(7.77±1.56)mm on the right respectively;The distance of the infraorbital foramen to cranial median line is(25.01±1.32)mm on the left side and(25.20±1.07)mm on the right respectively.The distance is also free from significant difference between the left and the right(P﹥0.05).④The distance of zygomatic frontal process to exo-superior cornu is(42.57±5.80)mm on the left side and(43.02±6.40)mm on the right,and the thickness of the anterior wall is(0.50±0.03)mm on the left side and(0.49±0.05)mm on the right respectively.Both of the distance and thickness on both sides are free from significant difference(P﹥0.05).Conclusion The particular observation on zygomatic structure is of far reaching importance for even better carrying out zygomatic reduction diorthosis and decreasing complications thereof.
