颈椎前路钢板椎间融合器系统治疗颈椎间盘突出症 总被引:1,自引:0,他引:1
颈椎前路手术在颈椎间盘疾病中已广泛应用,手术方法主要为颈前路减压加椎间植骨融合术。但不管是早期的自体骨融合的颈前路手术,还是后来进一步发展的颈前路钢板以及椎间融合器技术,都存在着诸如融合失败率高、植骨块移位、塌陷、螺钉断裂、钢板松动等并发症,造成手术疗效不佳以致于二次手术。自2002年2月-2004年1月采用颈椎间盘摘除、颈椎前路钢板椎间融合器(PCB)系统内固定、植骨融合术治疗颈椎间盘突出症后均无前述并发症的发生,疗效满意,现报道如下。 相似文献

Summary Ectopic salivary glands in the neck are very unusual lesions. Generally they are localized to the oropharyngeal region, near the mandible and para-parotid lymph nodes. They occur occasionally on the anterior border of the sternocleidomastoid muscle in the soft tissues of the neck. We wish to report on a singular association of ectopic salivary glands with partial hearing loss, preauricular fistula, palatoschisis, anal fistula, and an arteria lusoria. Morphological, histological and embryological aspects are discussed. 相似文献

椎动脉型颈椎病血浆内皮素变化 总被引:45,自引:0,他引:45
目的:通过观察内皮素(endothelinET)在椎动脉型颈椎病患者血浆中的变化,探讨其在该病中的病理学作用和意义。方法:用放射免疫方法分别对30例正常人和30例患者、20例椎动脉减压术患者术前和术后的血浆内皮素测定。结果:椎动脉型颈椎病患者血浆ET含量(119.46±58.65ng/l)明显高于正常对照组(38.34±14.33ng/l);20例手术患者术后ET含量(50.84±21.67ng/l)明显低于术前ET含量(139.34±52.56ng/l),经统计学t检验有显著性意义(P值<0.001)。结论:ET可能是椎动脉型颈椎病发病中的重要体液因素之一,探讨ET抗体和特异ET受体阻滞剂将为治疗该病提供新的启示。 相似文献

Co-existence of facial and occipital pain may occur in occipital neuralgia, migraine and cluster headache; suggesting convergence of trigeminal and cervical afferents. Such convergence has been shown in humans and other animals, but the site and extent of this are uncertain. In anaesthetized adult cats, the superior sagittal sinus and occipital nerve were stimulated electrically, and extracellular recordings made in the dorsolateral area of the upper cervical cord using glass-coated tungsten electrodes. Of 49 units in 10 cats, 33 (67%) had input from the superior sagittal sinus and the occipital nerve. Thirteen (27%) had superior sagittal sinus input and 3 (6%) had occipital nerve input. Convergent receptive fields were identified mechanically in 7 units. These experiments in cats show convergent input from occipital nerve and superior sagittal sinus on dorsolateral area units in two-thirds of cases studied. This experimental site of trigeminocervical convergence may relate to referral of pain in occipital neuralgia and other headaches. 相似文献

The choice of a surgical approach for multi-level cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) is still a controversial issue. While most of the surgeons are still performing decompression by laminectomy some are doing multi-level anterior decompression. Few neurosurgeons are performing decompression by corpectomy. We have treated 26 patients by median cervical corpectomy during the last 4 years. These patients were followed up for a mean period of 25 months. Twenty one (80%) patients had a good outcome, 2 patients remained unchanged and 3 expired. Review of the literature and our experience indicates that patients with CSM and OPLL should be operated by median cervical corpectomy (anterior approach). 相似文献

节段性不稳定在颈椎病性脊髓病发病中的作用 总被引:12,自引:0,他引:12
复习100例颈椎病性脊髓病患者的临床资料,并以正常成人49例作为对照,在颈椎侧位及伸、屈位X线片上测量椎管中矢径、椎体中矢径、功能Ⅰ径、功能Ⅱ径,颈伸位时椎体后滑距离,椎体后缘骨刺。将颈椎管中矢径比值小于0.75作为发育性椎管狭窄的判断标准,中矢径比值小于0.75为椎管狭窄组(A组),其余为非狭窄组(B组),将正常成人组定为C组。对所测数据进行统计学处理。用JOA法对脊髓病患者(A、B组)的颈脊髓功能做出评估。结果显示:A、B组中节段性不稳定(segmentalinstability,SI)发生率明显高于正常人,但不稳定程度(颈椎后滑)无明显差异。脊髓病损程度A组重于B组,在A组中与滑移程度正相关。A组功能Ⅰ径<Ⅱ径,B组功能Ⅰ径>Ⅱ径,提示节段性不稳定合并发育性椎管狭窄时具有致病作用。颈伸位时椎体后滑使功能Ⅰ径小于12mm为脊髓受压的临界标准。 相似文献

Based on recent genetic studies, we propose a progression model for the development of oral squamous cell carcinoma. In the initial phase, a stem cell acquires a genetic alteration; subsequently a patch is formed, a clonal unit consisting of the stem cell with its daughter cells that all share the DNA alteration. The next critical step is the conversion of a patch into an expanding field as a result of additional genetic alterations. This mucosal field replaces the normal epithelium and in the oral cavity such fields have been detected with dimensions of over 7 cm in diameter. Sometimes these fields are visible as leukoplakia. Ultimately, clonal selection leads to the development of carcinoma within this contiguous field of pre-neoplastic cells. An important clinical implication of this model is that fields often remain after surgery of the primary tumor and may lead to new cancers, presently designated by clinicians as second primary tumors or local recurrences. 相似文献

The purpose of this study was to investigate the histogenesis of experimental tumors in the rat esophagus. Thirty rats received 0.0015% N-methyl-N-amylnitrosamine (MNAN) in the drinking water for 12 weeks. Another 30 rats received tap water. All rats then received tap water until sacrifice. Rats from each group were sacrificed immediately after MNAN administration, four weeks after, and eight weeks after. One hour before sacrifice, [3H]TdR was injected by tail vein to label proliferating cells. The entire esophagus and stomach were removed and processed for light and electron microscopy and autoradiography. The overall frequency of esophageal tumors after MNAN was 83% and did not differ significantly among the three experimental groups. Tumors were primarily papillomas and squamous cell carcinomas and occurred with equal frequency in the upper, middle, and lower thirds of the esophagus. No tumors were found in the squamous-lined forestomach. Electron microscopy revealed abundant tonofilaments, free ribosomes, and mitochondria accompanied by vacuoles. By autoradiography, esophageal epithelial proliferation was markedly stimulated in nontumorous mucosa from all three experimental groups. We conclude that MNAN ingestion for 12 weeks reliably produces papillomas and squamous cell carcinomas throughout the rat esophagus, but not in the squamouslined forestomach, and that MNAN stimulated marked epithelial proliferation which is accompanied by thickening of the epithelium in nontumorus esophageal mucosa. 相似文献
