颊

Aim: To investigate the expression of vascular endothelial growth factor and its relationship with the prognosis of buccal squamous cell carcinoma.

目的 ：研究颊鳞状细胞癌组织中血管内皮生长因子表达与颊癌细胞生长、转移及预后的关系。

The contraction of the buccinator limits not so much the height as the width of the buccal flange.

颊肌收缩对义齿颊侧基托翼缘高度的限制较宽度为弱。

The buccal frenum is also a fold of mucous membrane, but varies in shape from a single fold to a broad fan. The levator anguli oris muscle passes beneath it and its action affects its position, as does theorbicularis oris and the buccinator. The former pulls the frenum forwards, the latter backwards.

颊系带同样是一个粘膜皱襞，但形态，从一个细窄条带状到宽平如盘状而变化多样；提口角肌从其下通过，并在收缩时影响颊系带的位置；同样，口轮匝肌和咬肌，前者使颊系带向前，后者使其向后运动。

Palatal fistulae were repaired by this method, 4 pedicled superior-anteriorly and 14 pedicled posteriorly, 7 of which got velopharyngeal incompetence correction at the same time. Results All of the patients got satisfactory fistula closure except 3 complications. One flap got partly necrosis and two got fistulae at the hard palate. However, the fistula sizes were reduced greatly and one has been re-repaired well by the transferred buccinator musculomucosal flap one year later.

结果：共修复腭瘘患者18例；其中15例腭部瘘孔获得关闭，颊肌黏膜瓣成活良好，无感染、腮腺导管损伤或阻塞、面神经损伤，无张口受限、瘢痕挛缩及咀嚼障碍；2例因岛状颊肌粘膜瓣远端愈合不良再次出现硬腭前端瘘口，但面积较原来明显减小，其中1例再发腭瘘应用已转移到腭部的颊肌粘膜瓣组织行二次手术修复后愈合；1例岛状颊肌粘膜瓣部分坏死。

The main performance of the period similar to upper respiratory tract infection symptoms:① fever in all cases, more than for the moderate fever;② cough, runny nose and tears, pharynx, such as congestive catarrhal symptoms, eye symptoms prominent conjunctival inflammation, eyelid edema, increased tears, photophobia, eyelid under the edge of a clear line of congestive, the diagnosis of measles very helpful ③ Koplik spots, eruptive in 24 ~ 48 hours prior to the emergence of about 1.0mm in diameter outside the gray dots red halo, found only at the beginning of the mucosa under the molars, but the increase in one day can be involved very quickly and spread to the entire buccal mucosa lip and mucous membrane after the rash appears in the gradual disappearance of skin rash may have a small dark red points;④ occasional skin urticaria, rash or scarlet fever faint rash appears when the typical skin rash disappeared;⑤ Some patients may have some non-specific symptoms such as general malaise, anorexia, etc.

这一期的主要表现类似上呼吸道感染症状：①发热见于所有病例，多为中度以上发热；②咳嗽、流涕流泪、咽部充血等卡他症状，以眼症状突出结膜发炎、眼睑水肿、眼泪增多畏光、下眼睑边缘有一条明显充血横线，对诊断麻疹极有帮助③Koplik斑，在发疹前24~48小时出现，为直径约1.0mm灰白色小点外有红色晕圈，开始仅见于对着下臼齿的颊粘膜上，但在一天内很快增多可累及整个颊粘膜并蔓延至唇部粘膜，粘膜疹在皮疹出现后即逐渐消失可留有暗红色小点；④偶见皮肤荨麻疹，隐约斑疹或猩红热样皮疹在出现典型皮疹时消失；⑤部分病例可有一些非特异症状，如全身不适、食欲减退精神不振等。

Being a microcosm himself, he discovers — and it is a true discovery, and he is the man to make it — that the world has been eating green apples; to his eyes, in fact, the globe itself is a great green apple, which there is danger awful to think of that the children of men will nibble before it is ripe; and straightway his drastic philanthropy seeks out the Esquimaux (16) and the Patagonian,(17) and embraces the populous Indian and Chinese villages; and thus, by a few years of philanthropic activity, the powers in the meanwhile using him for their own ends, no doubt, he cures himself of his dyspepsia, the globe acquires a faint blush on one or both of its cheeks, as if it were beginning to be ripe, and life loses its crudity and is once more sweet and wholesome to live.

他是大千世界里的一个缩影，他发现，这是一个真正的发现，而且是他发现的，——世界在吃着青苹果；在他的眼中，地球本身便是一只庞大的青苹果，想起来这却很可怕，人类的孩子如果在苹果还没有成熟的时候就去噬食它，那是很危险的；可是他那狂暴的慈善事业使他径直去找了爱斯基摩人、巴塔哥尼亚人，还拥抱了人口众多的印度和中国的村落；就这样由于他几年的慈善活动，有权有势者还利用了他来达到他们的目的，无疑他治好了自己的消化不良症，地球的一颊或双颊也染上了红晕，好像它开始成熟起来了，而生命也失去了它的粗野，再一次变得又新鲜又健康，更值得生活了。

Distobuccal root canals were found obvious curve out by the rate of 80% in mesiodistal direction,45% in buccolingual direction.

远中颊侧根管在近远中方向有80%，颊舌方向有45%出现大于5°的明显弯曲，弯曲位置多位于根中1/3，且近远中向的弯曲明显大于颊舌向（P.05）。

MB1 root canals of the mesiobuccal root canals in maxillary molars were found obvious curve out by the rate of 82.5% in mesiodistal direction, 77.5% in buccolingual direction and there is no difference of curvature degree in the two directions.

结果：1上颌第一磨牙腭侧根管通畅、较直。2远中颊侧根管在近远中方向有80%，颊舌方向有45%出现大于5的明显弯曲，弯曲位置多位于根中1/3，且近远中向的弯曲明显大于颊舌向(P.05)。3上颌第一恒磨牙近中颊根颊侧根管在近远中方向、颊舌方向分别有82.5%、77.5%出现大于5的明显弯曲。

Methods One band with a lingual button was bonded on the crown of lingual inclined lower second molar, then a removable, uprighter was put on, the tipping molar was uprighted by using buccal traction force produced by the latex elastics between the button and the hook of removable uprighter.

先在患牙上装戴一焊有舌侧扣的带环，再将预先制作好的带颊侧牵引钩的下颌可摘式磨牙颊向竖直器装戴就位，然后在舌侧扣与矫正器的牵引钩之间使用乳胶弹力圈对患牙进行颊向牵引。待患牙扶正后再使用固定矫正器进行精细调整。

Group 1 was instrumented with SS-K files by step-back technique, group 2 was instrumented with manual Protaper instruments according to manufacturers' directions.

第一组使用不锈钢K锉采用逐步后退法预备近颊根管，第二组使用手用Protaper采用厂家推荐的方法预备近颊根管，第三组使用机用K3采用逐步深入法预备近颊根管。
