骨性鼻背测量研究与隆鼻术并发症的分析

指导植入体的正确雕刻，减少由于植入体雕刻问题引起的隆鼻术后并发症。使植入体的形态恰到好处地补充骨性鼻背的缺陷。本文通过对７１个头颅标本进行鼻骨测量，对３２例正常成人进行骨性鼻背螺旋ＣＴ三维骨重建测量，并将各数据作统计学处理，测得各项目的平均值和标准差。通过对骨性鼻背测量的研究，对骨性鼻骨起点，植入体底面与骨性鼻背接触面的贴合，鼻额角的角度问题及植入体的宽度等问题有了更深刻的了解，从而认识到植入体雕刻必须以骨性鼻背形态为依据，隆鼻术的某些并发症的发生显然与其有着密切的关系。结论：１．通过测量得出植入体宽度应参照骨性鼻背前缘梨状孔顶间距宽度来确定。２．隆鼻术前必须充分了解骨性鼻背形态并据此雕刻鼻植入体，将有效地避免一些并发症的发生

Measurement of bony dorsum nasi for guiding nasal prosthesis's carving

Objective: To guide the carving of prosthesis correctly and to reduce the related post-operative complications. The bony dorsum nasi of 71 skull specimens and 32 normal adults were measured either by naked eye or three-dimensional bone reconstruction by spiral CT. All data were handled by statistical methods. Result: definite understanding were got about the following: origin of the bony dorsum nasi, fitness of contact surfaces between prosthesis and the bony dorsum nasi, angulation of nasofrontal angle and width of prosthesis. We realize that the carving of prosthesis should be based on the morphology of the bony dorsum nasi, or some related complications would occur. Conclusion 1. The width of prosthesis should be defined according to the distance between the pyriform aperture's vertices. 2.The incidence of complication will be reduced greatly when the morphology of the bony dorsum nasi is fully understood and depending on it the prosthesis is carved before operation.
