Variability of the bony structures located in the maxillary sinus, and of the lateral nasal wall topography, have practical significance during surgical procedures conducted by maxillofacial surgeons or otolaryngologists. The retrospective analysis of 111 computed tomography examinations of patients (52 male and 59 female) diagnosed in our institution was made to evaluate anatomical variations of the maxillary sinus. In the study the frequency of the Haller cell was 29/222 (13%), and the prevalence of one or more septa per sinus was 49/222 (26%). The infraorbital recess was found in 6/222 (3%) of cases. The mean width of the nasal duct was enlarged at the side where the Haller cell was present (p < 0.01) or where bony septa were absent in the maxillary sinus (p < 0.01). Bony structures of the maxillary sinus and changes in topography of the lateral nasal wall should compel surgeons to carefully analyze the computed tomography scans before operations in this area.
位于上颌窦的骨结构以及鼻侧壁形态的变异性，在颌面外科医生或耳鼻喉科医生进行的外科手术中具有实际意义。对在我们机构诊断的111例患者（52例男性和59例女性）的计算机断层扫描检查进行回顾性分析，以评估上颌窦的解剖变异。在该研究中，Haller气房的出现频率为29/222（13%），每个鼻窦有一个或多个间隔的发生率为49/222（26%）。眶下隐窝在6/222（3%）的病例中被发现。在存在Haller气房的一侧（p < 0.01）或上颌窦中无骨间隔的一侧（p < 0.01），鼻泪管的平均宽度增大。上颌窦的骨结构和鼻侧壁形态的变化应促使外科医生在该区域手术前仔细分析计算机断层扫描图像。
