鼻上颌窦的

Result:The two cases were all cured without lesion reoccurring by the end of following up period within 10 and 13 years.Conclusions:There is a close with congenital of chondroma.The clinical manifestation of chondroma in sinonasal and nasopharyngeal were complex.

结果：1例肿瘤位于均筛窦，破坏上颌窦内侧骨壁突向上颌窦腔及鼻腔；1例其基底位于以圆枕为中心的鼻咽侧壁，病理结果均诊断为软骨瘤，手术切除全部治愈，追踪分别10年和13年无复发。

Important issues about pediatric rhinosinusitis were also addressed in our studies. First, we tried to compare the results obtained by endoscopic middle meatal culture and maxillary sinus punctures in children with rhinosinusitis. Our data demonstrated that, when performed in pediatric patients (especially in children with younger age), the correlation between endoscopic middle meatal culture and maxillary sinus puncture was not as favorable as in the case of adult patients.

我们的研究也探讨了几项儿童鼻及鼻窦炎的重要课题，首先，我们比较鼻及鼻窦炎病童上颌窦穿刺与内视镜中鼻道培养的报告，结果显示，在儿童鼻及鼻窦炎的培养上，内视镜中鼻道采样与上颌窦穿刺的培养结果一致性没有在成人运用时理想，特别是在年纪小的病童。

Objective: To explore the role of enlarging ostium maxilare on chronic maxillary sinusitis in endoscopic sinus surgery.

摘要目的：探讨鼻内镜手术中扩大上颌窦自然口对上颌窦炎转归的影响。

It can prevent the ostium of maxillary sinus from closing, drain the empyemata from maxillary sinus and send the medicament to the field of ostiomeatal complex.

目的设计一种应用于功能性内窥镜鼻窦手术后的引流器，可以在上颌窦术后防止窦口的粘连，通过鼻腔呼吸气流将上颌窦内的积液引出，及将药物输送到窦口鼻道复合体处，方便术后的管理。

A subject was selected strictly from 30 healthy young people through nasal endoscopic examination, acoustic rhinometry measurement and CT scanning. Based on the CT image data of the subject, digital model of normal nasal cavity was reconstructed through Fluent 6.1.22 software. At the same time, according to the surgical requirements of FESS (remove the uncinate process and open the ethmoid sinus, maxillary sinus, and sphenoid sinus), post-FESS digital nasal cavity model was simulated. The viscous motion of nasal airflow before and after FESS was calculated by Navier-Stokes equations to compare the differences of airflow velocity, distribution, and pressure.

从30例健康青年人中，通过鼻内镜、鼻声反射测定仪及CT检查，严格筛选出一例研究对象，根据该入选对象的鼻腔CT影像资料，利用Fluent 6.1.22软件重建出正常鼻腔的数字模型，同时根据功能性鼻窦内镜手术的要求（切除钩突，开放筛窦、上颌窦和蝶窦）模拟出鼻内镜术后的鼻腔数字模型，再用Navier-Stokes方程对手术前后鼻腔气流的粘性运动进行数值计算，比较内镜手术前后鼻腔的气流速度、分布和压力的差异。

Among the sampling methods used to investigate the pathogens responsible for rhinosinusitis, maxillary sinus puncture is considered to be the gold standard. Although endoscopic middle meatal culture seems to correlate well with the results obtained by maxillary sinus puncture, the reliability of documentation of bacteria by endoscopic culture in children with rhinosinusitis is still unknown. Finally, because studies on current bacterial resistance patterns in pediatric patients are limited, we employed maxillary sinus puncture to obtain sinus secretions for bacterial culture and analysis of antibiotic resistance in children with chronic rhinosinusitis.

关於鼻窦的培养方法，一般而言上颌窦穿刺为公认获得鼻窦细菌培养的准则，虽然证据显示在成人使用内视镜中鼻道培养的结果与上颌窦穿刺所获得的培养结果相关性很高，不过目前儿童使用内视镜中鼻道培养的可信度依然不明，因此我们的研究也比较鼻及鼻窦炎病童上颌窦穿刺与内视镜中鼻道培养的结果，以厘清在儿童使用内视镜中鼻道采样培养鼻窦致病菌的可信度。

Maxillary sinus puncture was performed on these patients both for sampling of sinus contents and irrigation of the diseased sinuses. Aspirate contents of the sinuses were collected for aerobic and anaerobic cultivation. 3 A prospective study of pediatric patients with community-acquired rhinosinusitis was conducted. Bacterial culture was performed on the specimens obtained from maxillary sinus by puncture and middle meatus by endoscopic sampling. The correlation and diagnostic usefulness of endoscopic middle meatal culture versus maxillary sinus puncture were determined.

我们搜集鼻咽癌放射线治疗后患有急性上颔窦炎的病人，以上颔窦穿刺搜集这些病患的鼻窦分泌物并冲洗其患病的鼻窦，收集到的鼻窦分泌物则送往实验室做细菌培养。3 我们执行前瞻性研究，收集患有社区感染鼻及鼻窦炎的儿童，这些病童会同时接受内视镜中鼻道培养与上颌窦穿刺培养，为了厘清儿童使用内视镜中鼻道培养的可信度，我们计算内视镜中鼻道培养与上颌窦穿刺培养结果的关联性与诊断测试。

Objective:To provide detailed anatomical data of the theory and practice for endoscopic surgery in the PPF by studying the related applied anatomy of PPF through the lateral wall of the nasal cavity approach of endoscopic middle meatal transpalatine approach、middle meatal transantral approach and inferior turbinectomy transantral approach respectively.

Results The penumatization rate of total or inferior part of middle turbinate correlated positively to the inflammation of anterior ethmoid and maxillary sinuses. Compared with patients with normal frontal sinuses, the vertical diameters of agger nasi cells of patients with frontal sinusitis were larger(11.70±5.50 mm and 8.54±3.67 mm respectivevy, p＜0.01).Compared with patients with normal maxillary sinuses, the Haller's cells of patients with maxillary sinusitis were larger (77.8% and 33.3%,P＜0.05)and the amount of inflammatory Haller's cells of the latter was more abundant than that of the former(91.6±17.8 mm2 and 41.6±12.6 mm2, respectively, P＜0.05). The deviation of uncinate process was one of the factors of maxillary sinusitis .The sizes of ethmoid bullae increased with the soft tissue thickening in anterior ethmoid sinus, the large ethmoid bulla may cause anterior ehmoid sinusitis.

结果 全中甲或中甲下部气化的发生率随前筛、上颌窦内软组织影增厚而升高；有额窦炎组病人的鼻丘气房最大纵向垂径明显大于无额窦炎组(分别为11.7±5.5 mm和8.5±3.7 mm，P＜0.01)；Haller气房在上颌窦炎组和非上颌窦炎组的发生率无显著差异，但前组发生炎症的Haller气房明显多于后组(分别为77.8%和33.3%，P＜0.05)，且前组Haller气房的冠状位截面积明显大于后组(分别为91.6±17.8 mm2和41.6±12.6 mm2，P＜0.05)；钩突角度随上颌窦内软组织增厚而减小；筛泡冠状位截面积随前筛窦内软组织增厚而增大(P＜0.01)。
