有上颌的

Sanctus. Mandibular fenestra expanded anteriorly. Maxilla protruding more anteriorly than in C. sanctus. Wing claw less developed. Sternum relatively elongate with a "V"-shaped anterior notch. Sternum with a pair of short posterior proceses. Tarsometatarsus relatively short. Pygostyle expanded distally.

上颌骨较圣贤孔子鸟向前突出，指骨爪没有圣贤孔子鸟那样伸长、强壮，胸骨比较拉长，前喙中央有一凹刻构造成"V"字形，同时胸骨两侧有一对短的后侧突，跗蹠骨较圣贤孔子鸟短，以及尾综合、骨末端膨大。

Results The position of the maxilla after orthopedics was significantly advanced (P .001), but there was still difference from normal values.

结果治疗后上颌骨的位置前移变化有显著性(P＜0.01)，但与正常值之问也存在一些差异。

There is one cavea on either side of the nose, which is called "maxillary sinus".

在鼻腔的两侧各有1个空腔，称为"上颌窦"。

Correlation obtained from the middle meatus with those from the maxillary sinus puncture was demonstrated in 32 of 41 specimens (78.0%).

本研究共收集到41套样本做嗜氧菌培养，在这41套样本中有32套(78.0%)内视镜中鼻道培养的结果与上颌窦穿刺培养一致。

Results: Among the 47 cases, 33 cases were teeth pulpless tissue including 14 endodentically treated teeth and 14 cases were vital teeth with periodontitis, cracked tooth and occlusal traumatism.

结果：牙冠纵折多见后牙，以上颌第一磨牙为多见，其中无髓牙33例，牙折裂前有近一半曾作过根管治疗，活髓牙14例，存在不同程度的牙隐裂，牙周炎和咬合创伤。

It is concluded:①The method does not traumatize the periosteum of the hard palate,thus alleviating postoperative maxillary deformity;②The buccal musculomucosal flap is generally long enough to reach across the incisive foramen and maintain good blood circulation;③The method benefits reconstruction of the levator sling and facilitates velopharyngeal closure.

该方法有以下优点：①手术不剥离硬腭区粘骨膜，对上颌骨的损伤很小，减轻了上颌骨的发育障碍；②采用两块带蒂颊粘膜肌瓣重建了腭帆提肌功能，促使异位的提肌悬吊再形成；③血运良好的颊粘膜肌瓣插入于软硬腭交界处，能使软腭充分后退，实现腭咽闭合，而且可有效地防止瘘孔的发生。

The treatment of PPS tumor is primarily exairesis by the transoral approach, cervical approach, cervical-parotid approach, mandible split swing approach and maxillary swing approach.

PPS肿瘤的治疗以手术切除为主，手术径路有经口径路、颈侧径路、颈腮腺径路、下颌骨裂开外旋径路、上颌骨外旋径路。

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。

Radiograph of teeth in mesiodistal direction were taken.

结果 ：单根单根管上颌第二前磨牙的根管弯曲仅有 2个，单根双根管牙齿的根管明显弯曲有 6个，在 2 8个双根牙中有明显根管弯曲的 6个，根管弯曲的牙齿总发生率为 6 。6 %(14 /2 13)。

Sternum with a pair of short posterior proceses. Tarsometatarsus relatively short. Pygostyle expanded distally.

上颌骨较圣贤孔子鸟向前突出，指骨爪没有圣贤孔子鸟那样伸长、强壮，胸骨比较拉长，前喙中央有一凹刻构造成&V&字形，同时胸骨两侧有一对短的后侧突，跗蹠骨较圣贤孔子鸟短，以及尾综合、骨末端膨大。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
