【摘要】 目的 根据国际额窦解剖分类(International Frontal Sinus Anatomy Classification，IFAC)确定额窦相关头痛患者额隐窝气房变异的出现率，探讨额隐窝气房变异在额窦相关头痛发病中的作用。方法 回顾46例额窦相关头痛接受鼻内镜手术治疗患者的鼻窦CT，分析其额隐窝引流区域的额隐窝相关气房，并分析中鼻道变异和鼻窦受累情况。观察其在头痛与否之间表达是否有差异。结果 92侧鼻窦CT中，鼻丘气房(agger nasi cell，ANC)出现率为100%(92/92)，其次筛泡上气房(supra bulla cell，SBC)为78.3%(72/92)，鼻丘上气房(supra agger cell，SAC)为67.4%(62/92)，筛泡上额气房(supra bulla frontal cell，SBFC)为27.2%(25/92)，鼻丘上额气房(supra agger frontal cell，SAFC)为20.7%(19/92)，额窦间隔气房(frontal septal cell，FSC)为8.7%(8/92)，眶上筛房(supraorbital ethmoid cell，SOEC)为0%(0/92)。在传统的额窦引流区域，IFAC分类中的SBFC(P=0.0108)和SAC(P=0.0104)和SAFC(P=0.0088)与额窦相关头痛的发生有显著相关。中鼻道变异如泡状中鼻甲也表现出和额窦相关头痛的发生明显相关(P=0.0390)。结论 在额隐窝引流通道中，SAC、SAFC、SBFC及泡状中鼻甲的发育异常均与额窦相关性头痛具有明显的相关。更多还原

【Abstract】 OBJECTIVE To determine the prevalence of frontal recess cells variations in patients with frontal sinus associated headache according to the International Frontal Sinus Anatomy Classification(IFAC).METHODS A retrospective study was conducted on the CT scans of sinuses in patients with frontal sinus associated headache.We reviewed 46 patients with frontal sinus-related headache who had clinical symptoms and were relieved after nasal endoscopic surgery.The development of frontal recess cells in the frontal recess drainage area was analyzed,and the variation of middle meatus and sinus involvement were analyzed in the same time.The Anatomical variations and imaging characteristics of frontal recess cells development in patients with frontal sinus associated headache were analyzed.RESULTS A total of 92 sinus CT profiles were analyzed in 46 patients.The most common cells were agger nasi cell(ANC)(100%,92/92),followed by supra bulla cell(SBC)(78.3%,72/92),supra agger cell(SAC)(67.4%,62/92),supra bulla frontal cell(SBFC)(27.2%,25/92),supra agger frontal cell(SAFC)(20.7%,19/92),frontal septal cell(FSC)(8.7%,8/92) and supraorbital ethmoid cell(SOEC)(0%,0/92).In the conventional frontal sinus drainage area,SAFC(P=0.0108),SAC(P=0.0104) and SAFC(P=0.0088) in the IFAC classification were significantly associated with the occurrence of frontal sinus associated headache.At the same time,the middle concha bullosa also showed a significant correlation with the occurrence of frontal sinus associated headache in the lower segment of the frontal recess drainage channel(P=0.0390).CONCLUSION In the frontal recess drainage channel,the abnormal development of SAC,SAFC,SBFC and the middle concha bullosa are significantly correlated with frontal sinus associated headache.更多还原
