分段式鼻中隔成形术临床疗效分析

目的:探讨分段式鼻中隔成形术的可行性及疗效。方法:选取60例鼻中隔偏曲患者,根据偏曲部位的不同,采取分段式鼻中隔成形术,Ⅰ型适用于偏曲位于软骨部,Ⅱ型适用于偏曲位于筛骨垂直板,Ⅲ型适用于偏曲位于上颌骨鼻突或嵴突者,Ⅳ型适用于骨部及软骨部均存在偏曲者。结果:所有患者均顺利完成手术,手术时间平均约30min,术中出血平均约5ml,术后随访半年后评定疗效。60例患者术后鼻中隔偏曲均校正满意,鼻通气良好,无鼻中隔血肿、脓肿及鼻中隔穿孔、鞍鼻等发生。治愈56例(93.33%);显效4例(6.66%);总有效率为100%。结论:分段式鼻中隔成形术是一种更加微创的矫形手术,其在临床上尤其是青少年鼻中隔偏曲患者中有着广阔的应用前景,值得临床推广。     

鼻中隔骨及软骨拼接缝合支架重建治疗青少年鼻中隔偏曲

鼻中隔偏曲是青少年鼻出血、反射性头痛、鼻阻、鼻窦炎的常见病因,需行手术治疗[1],由于青少年鼻面部正处于发育阶段,大多数医师为避免并发症的发生往往建议患者成年后行鼻中隔矫正术,因此造成疾病迁延及加重,严重影响青少年的身心健康.为了及早干预因鼻中隔偏曲引起的症状及体征,我科采用鼻中隔骨、软骨拼接缝合支架重建治疗青少年鼻中隔偏曲,效果良好,报告如下.     

鼻内镜减张法治疗青少年鼻中隔偏曲8例疗效观察

青少年鼻中隔偏曲常易引起鼻出血、反射性头痛、鼻塞、鼻窦炎等并发症,传统观点认为,未成年人行鼻中隔偏曲矫正术会影响鼻及面部的发育,对青少年鼻中隔偏曲不主张行鼻中隔手术.     

鼻中隔偏曲的矫正效果和长期随访

虽然鼻中隔偏曲在各种族各年龄组均可发生,但以青少年和儿童更常见,近来更认为也发生在出生时。因此对出生时查觉的鼻中隔偏曲行早期手术矫正是很重要的。作者报道了新德里医学研究院1980～1985年间401例新生儿的研究结果。新生儿均系从保育室随机所选,不包括早产儿。研究于出生后第一周开始,分两阶段进行。第一阶段201例中有31例鼻中隔偏曲,占15.4％,均按Gray氏法矫正,随访约     

经鼻内窥镜鼻中隔偏曲矫正术200例分析

目的：研究经鼻内窥镜鼻中隔偏曲矫正术后相关鼻部症状改善情况,探讨鼻中隔偏曲形态与鼻窦炎、鼻息肉、嗅觉障碍、鼻出血等鼻部疾患之间的内在联系;以指导临床经鼻内窥镜手术中合理进行鼻中隔偏曲的处理。 方法：对２００例鼻中隔偏曲患者术前、术后相关临床症状改善情况进行回顾性分析：２００例患者中,单纯鼻中隔偏曲致鼻塞者２８例,伴慢性鼻炎者６０例、鼻息肉（Ｉ型）者８０例、慢性鼻窦炎鼻息肉（Ⅱ型）者１６例、慢性鼻窦炎鼻息肉（Ⅲ型）者 ４例（ＦＥＳＳ－９７海口标准）,反复发作鼻出血者１２例;８０例有不同程度的嗅觉障碍…     

鼻腔粘连合并鼻中隔偏曲的手术治疗

目的 探索鼻腔粘连合并鼻中隔偏曲的手术治疗方案.方法 鼻腔粘连合并鼻中隔偏曲患者13例.其中11例在施行粘连分解术的同时行鼻中隔偏曲矫正术和Merocel膨胀海绵持续性填塞鼻腔,1例施行单纯粘连分解术,1例联合施行粘连分解和鼻中隔偏曲黏膜下切除术.术后观察比较鼻腔创伤愈合情况及其功能改善效果.结果 第1组病例均获得痊愈;行单纯粘连分解术的1例症状无改善,改用第1组所用治疗方法后获得成功;第3种术式治疗的病例虽然粘连成功分解,但发生了鼻中隔穿孔.结论 对鼻腔粘连合并鼻中隔偏曲的患者,需在分解粘连的同时施行鼻中隔偏曲矫正术,重建鼻中隔,并行Merocel膨胀海绵持续性鼻腔填塞,有利于创伤愈合.     

鼻腔结构与真菌性上颌炎关系的CT影像学研究

目的 探讨真菌性上颌窦炎是否存在鼻腔解剖结构异常。 方法 分析102例真菌性上颌窦炎患者(单侧患病)的CT图像,观察鼻中隔、中鼻甲、钩突、筛泡的变异情况,有无Haller气房;测量冠状位钩突平面下鼻甲、钩突和中鼻甲所占该平面鼻腔面积比。 结果 鼻中隔偏曲87例(85.29%),其中51例宽敞侧发病,36例狭窄侧患病(P<0.05)。高位偏曲病例与低位偏曲相近。高位偏曲病例中,宽敞侧患病例数多于狭窄侧(P>0.05),但无统计学差异。低位偏曲病例中,两侧患病例数差异无统计学意义。患侧与健侧中鼻甲、钩突、筛泡变异及Haller气房出现情况患侧反向中鼻甲明显多于健侧,差异有统计学意义。钩突偏曲、Haller气房两侧差异有统计学意义,筛泡过度气化患侧较健侧多,但无统计学意义。冠状位钩突平面下鼻甲、钩突和中鼻甲所占该平面鼻腔面积比,两侧差异无统计学意义。 结论 鼻中隔偏曲及中鼻甲、钩突变异可能是真菌性上颌窦炎致病因素,真菌性上颌窦炎手术应同时处理相应变异结构。     

鼻内镜下鼻中隔偏曲的个体化手术治疗

目的 观察鼻内镜下个体化手术治疗鼻中隔偏曲的疗效.方法 对32例鼻中隔偏曲患者行鼻内镜下个体化鼻中隔偏曲矫正手术.结果 术后随访1～6月,30例治愈,2例好转,无鼻中隔穿孔等严重并发症发生.结论 由于鼻中隔偏曲的个体差异性,通过鼻内镜下个体化的鼻中隔矫正手术,有利于达到手术的微创性和功能性.     

Comparative study on the morphology and the composition of the otoliths in the teleosts

Conclusion. Saccular otoliths of teleosts were mostly larger than utricular otoliths, which might relate to the three-dimensional movement. The large and heavy otolith may be better suited in saccules of the bottom and reef fishes. The quantities of iron in lagenar otoliths were found to be lower than those of birds. The function of the fish lagena remains to be elucidated by further studies. Objective. To evaluate the morphological characteristics and the chemical composition of the otoliths in fishes as related to behaviour and habitat. Materials and methods. We studied the morphology of the otoliths of 18 genera of fishes (81 samples) divided into 3 groups: saltwater fish (13 genera), freshwater fish except for the carp family (3 genera) and carp family fish (2 genera). The otoliths and the living environments were compared. The chemical composition was analysed using a synchrotron X-ray fluorescence analyser. Results. Bottom fishes generally have larger saccular otoliths, and migrating fishes have smaller saccular otoliths. In comparing the bottom/reef fishes and the migrating fishes in salt water, the former tended to have larger saccular otoliths. In saltwater bottom fishes the tendency was found that the thinner the head, the larger was the saccular otolith. We found significant quantities of iron, zinc and manganese in the lagenar otoliths.
