摘要

研究目的根据 CT 扫描结果研究上颌窦囊性形成的位置特征,并确定其与上颌牙齿病理学的关系。材料和方法。研究分析了 552 例由耳鼻喉科医生或牙科医生转诊检查的患者的头部计算机断层扫描图像。接受检查的总人数为 552 人,其中女性占 44.7%,男性占 55.3%,年龄在 18-74 岁之间。调查使用 NewTom GO 设备进行,测量范围为 155-172 mGy/cm±10%,误差为 ±4.24%。使用 STATISTICA v.12.6 软件对数据进行统计处理。结果在分析的 552 张计算机断层扫描图像中,选取了 79 名单发囊肿患者的 92 张上颌窦(MS)图像。他们被分为两组。第一组包括上颌窦下壁囊肿患者(76 人)。第二组包括囊肿位于其他壁的患者(16 人)。对上颌 4、5、6、7 齿根与上颌下壁比例的评估显示,第 1 组的突出频率(42.1%)明显高于第 2 组(18.7%)。同时,第 2 组患者这些牙齿上的骨平均厚度(3.4 ± 1.09 毫米)明显大于第 1 组(1.9 ± 0.92 毫米)(P=0.0003)。此外,在 33.7% 的病例中,囊肿与突出牙齿的深层结构受累和炎症扩散到 MS 下壁有关。结论在由耳鼻喉科医生或牙医转诊进行 CT 检查以通过放射学证实鼻腔、副鼻窦和上颌牙齿病理过程的患者中,有 19.6% 的病例发现了 MS 囊肿,其中 83% 的囊肿位于其下部。在多发性硬化症下部有囊肿的患者中,与多发性硬化症其他部位有囊肿的患者相比,更常观察到牙根突出到窦腔中,且其上的骨层较薄。在多发性硬化症牙槽凹处囊肿形成的患者中,34%的病例可发现上颌牙齿病变的放射学迹象。

RADIOLOGICAL FEATURES OF THE LOCATION OF CYSTIC FORMATIONS IN THE MAXILLARY SINUS AND THEIR RELATIONSHIP WITH ALVEOLAR BONE PATHOLOGY OF THE UPPER JAW
The aim of the study. To study the features of the location of cystic formations in the maxillary sinus based on CT scans and to determine their relationship with the pathology of the upper jaw teeth. Materials and methods. The study involved the analysis of 552 head computed tomography scans of patients referred for examination by an otolaryngologist or dentist. The total number of individuals examined was 552, comprising 44.7% females and 55.3% males, aged 18-74 years. The investigation was conducted using the NewTom GO device with a measurement range of 155-172 mGy/cm±10%, with an error of ±4.24%. Statistical processing of data was carried out using the STATISTICA v.12.6 software. Results. Out of 552 computed tomography images analyzed, 92 images of individual maxillary sinuses (MS) of 79 patients with single cysts were selected. They were divided into two groups. Group 1 involved patients with cysts on the lower wall of MS (n=76). Group 2 included patients with cysts on other walls (n=16). The assessment of the ratio of 4, 5, 6, 7 tooth roots of the upper jaw to the lower wall of the upper jaw showed that the protrusion frequency in Group 1 was significantly higher (42.1%) compared to Group 2 (18.7%). Meanwhile, the average thickness of the bone over these teeth in Group 2 was significantly greater (3.4 ± 1.09 mm) than in Group 1 (1.9 ± 0.92 mm) (p=0.0003). In both patient groups, the greatest thickness was observed over tooth 4, and the smallest over tooth 7. Additionally, in 33.7% of cases, the cyst was associated with involvement of deep structures of the projecting teeth and the spread of inflammation to the lower wall of MS. Conclusions. Among patients referred by an otolaryngologist or dentist for CT examination to radiologically verify pathological processes in the nasal cavity, paranasal sinuses, and the upper jaw teeth, MS cysts were detected in 19.6% of cases, with 83% of them being localized in its lower parts. In patients with cysts located in the lower parts of MS, the roots protruding into the sinus cavity and a thinner layer of bone over them are more frequently observed compared to those where cysts are located in other areas of MS. In patients with cystic formations in the alveolar recess of MS, radiological signs of pathology of the upper jaw teeth are detected in 34% of cases.
