Haller's cells or infraorbital ethmoid cells refer to the ethmoidal pneumatization of the superior aspect of the maxillary sinus, and floor of the orbit can be seen on panoramic radiographs. They appear as well-defined, round-, oval-, or teardrop-shaped radiolucencies with smooth corticated or noncorticated borders.
To determine the prevalence and scrutinize the characteristics of Haller's cells on panoramic radiographs.
The present study is a cross-sectional study carried out in institutional setting.
The study group comprised 300 individuals with an age range of 08-80 years selected by convenient sampling method. Three hundred panoramic radiographs were examined for the presence of Haller's cells under ideal viewing conditions by two radiologists.
The data collected were tabulated and subjected to statistical analysis using SPSS version 20 for Windows (SPSS Inc., Chicago, IL, USA) to obtain the results. Chi-square test was performed, and significance was set at 0.05 levels.
Haller's cells were identified in 30/300 individuals giving a prevalence of 10% with 18 Haller's cells in males and 12 in females. Among the 30 Haller's cells, 14 were unilateral and 16 were bilateral. Most of the Haller's cells were oval followed by round shape.
The overall prevalence of Haller's cells is relatively low and is in harmony with other studies conducted in various geographic populations. Knowledge of Haller's cells while interpreting panoramic radiographs is essential to forewarn surgeons before endonasal procedures, thus preventing any untoward intraoperative complications.
哈勒氏气房或眶下筛窦气房是指上颌窦上方的筛窦气化，在全景片上可观察到眶底。它们表现为边界清晰的圆形、椭圆形或泪滴状透光区，边界有光滑的骨皮质或无骨皮质。
确定全景片上哈勒氏气房的患病率并仔细研究其特征。
本研究是在机构环境中进行的横断面研究。
研究组由300名年龄在8 - 80岁之间的个体组成，采用方便抽样法选取。由两名放射科医生在理想的观察条件下检查300张全景片，以确定是否存在哈勒氏气房。
收集的数据进行列表，并使用Windows版SPSS 20（美国伊利诺伊州芝加哥市SPSS公司）进行统计分析以获得结果。进行卡方检验，显著性设定为0.05水平。
在300名个体中，有30人发现哈勒氏气房，患病率为10%，其中男性有18个哈勒氏气房，女性有12个。在这30个哈勒氏气房中，14个为单侧，16个为双侧。大多数哈勒氏气房为椭圆形，其次是圆形。
哈勒氏气房的总体患病率相对较低，与在不同地理人群中进行的其他研究结果一致。在解读全景片时了解哈勒氏气房对于在鼻内手术前预先警告外科医生至关重要，从而防止任何术中不良并发症。
