Abstract

OBJECTIVES: The purpose of this study is to analyze and assess the frequency of anatomical variants of paranasal sinuses scanned by multidetector computed tomography (MDCT). METHODS: A total number of 225 patients (122 males, 103 females) with a median age of 28 (15-77) years were included in this retrospective study. We analyzed the presence of the nasal septal deviation (NSD), variations of the nasal turbinates, ethmoidal air cells, paranasal sinus pneumatization, accessory pneumatization of the paranasal complex, variations of the sphenoid sinus related structures and the optic nerve and vidian canal classification in the paranasal computed tomography (CT) of the selected patients. RESULTS: NSD was present in 124 (55.1%) patients, superior concha pneumatization in 30 (13.3%), middle concha pneumatization in 100 (44.4%), agger nasi cells (ANC) in 192 (85.3%), Haller cells in 47 (20.9%), Onodi cells in 44 (19.6%), maxillary sinus hypoplasia in 6 (2.6%), frontal sinus hypoplasia in 29 (12.9%), frontal sinus aplasia in 7 (3.1%), sphenoid sinus hypoplasia in 7 (3.1%), uncinate process pneumatization in 12 (5.3%), anterior clinoid process (ACP) pneumatization in 60 (26.7%) and pterygoid process (PP) pneumatization in 75 (33.3%) patients. Optic nerve Type 1 was detected in 122 (54.2%) patients, Type 2 in 29 (12.9%), Type 3 in 36 (16%) and Type 4 in 38 (16.9%) patients. Vidian canal Type 1 was observed in 37 (16.4%), Type 2 in 95 (42.2%) and Type 3 in 93 (41.3%) patients. CONCLUSION: The analysis of the paranasal CT is crucial in diagnosis of miscellaneous diseases of the paranasal sinuses. The anatomical variations of the sinuses are prevalent among the population, so otolaryngologists should be aware of these variations for precise diagnosis and to avoid surgical complications.

鼻窦CT解剖变异的评价

目的：本研究的目的是分析和评估多探测器计算机断层扫描（MDCT）扫描的鼻窦解剖变异的频率。方法：本回顾性研究共纳入225名患者（122名男性，103名女性），中位年龄为28岁（15-77岁）。我们在所选患者的鼻旁计算机断层扫描（CT）中分析了鼻中隔偏曲（NSD）的存在、鼻甲、筛窦空气细胞的变化、鼻窦气化、鼻窦复合体的副气化、蝶窦相关结构的变化以及视神经和视管分类。结果：NSD患者124例（55.1%），上鼻甲气化30例（13.3%），中鼻甲气化100例（44.4%），agger nasi细胞192例（85.3%），Haller细胞47例（20.9%），Onodi细胞44例（19.6%），上颌窦发育不良6例（2.6%），额窦发育不良29例（12.9%），额骨发育不全7例（3.1%），钩突气化12例（5.3%），前床突气化60例（26.7%），翼突气化75例（33.3%）。122例（54.2%）患者检测到视神经1型，29例（12.9%）患者检测出视神经2型，36例（16%）患者检测发现视神经3型，38例（16.9%）患者发现视神经4型。Vidian管1型37例（16.4%），2型95例（42.2%），3型93例（41.3%）。结论：鼻窦CT检查对鼻窦杂病的诊断具有重要意义。鼻窦的解剖变异在人群中很普遍，因此耳鼻喉科医生应该意识到这些变异，以进行精确诊断并避免手术并发症。
