Abstract

Studies have reported the incidence of anatomical variants of the paranasal sinuses for specific populations with a view to helping surgeons avoid possible complications during functional endoscopic sinus surgery. Some have found significant variation when comparing different populations. The current study has used computed tomography (CT) scans to observe variations in the paranasal sinuses in a non-random sample of museum skulls of Melanesians, a racial group that has not previously been studied in this respect. The incidence of variants found were: agger nasi cells 59.5%, concha bullosa 41.5%/o, Haller's air cells 31.7%, internal carotid artery bulge in the sphenoid sinus 23.8%/, supraorbital cells 16. 7%, paradoxical curvature of the mid-dle turbinate 7.5% and pneumatization of crista galli 7.1%.Because of contradictory findings in the literature as to the incidence of such variations between racial groups the authors are able to make only limited meaningful comparisons between their subjects and other such groups.

摘要

研究报告了特定人群的鼻窦解剖变异发生率，以期帮助外科医生在功能性内窥镜鼻窦手术中避免可能出现的并发症。一些研究在比较不同人群时发现了显著的差异。本研究使用计算机断层扫描（CT）观察了一组非随机的美拉尼西亚人头骨标本中鼻窦的变异情况，此前尚未在这方面对这一人种群体进行过研究。发现的变异发生率如下：气房（agger nasi cells）59.5%，泡状鼻甲（concha bullosa）41.5%，筛泡（Haller's air cells）31.7%，蝶窦内颈内动脉膨出（internal carotid artery bulge in the sphenoid sinus）23.8%，眶上裂（supraorbital cells）16.7%，中鼻甲的反常弯曲（paradoxical curvature of the middle turbinate）7.5%和鸡冠气房（pneumatization of crista galli）7.1%。由于文献中关于种族群体之间这种变异发生率的研究结果相互矛盾，作者只能对其研究对象与其他此类群体之间进行有限的有意义的比较。
