MRI对累及头颈部淋巴组织病变的鉴别意义

目的:基于累及头颈部淋巴组织病变的临床不典型性,旨在探讨MRI对其进行鉴别诊断的客观依据。方法:对本组22例可疑累及头颈部淋巴组织的各类病变进行MRI检查并与病理学结果进行对照。结果:MRI对本组22例累及淋巴组织病变的诊断与病理学诊断的符合率(21/22)约为95%。结论:MRI是对累及头颈部淋巴组织病变的重要检查手段,并能为明确其诊断提供客观依据。     

双头加压螺纹钉贴股骨距内固定治疗股骨颈骨折

在Ｘ光电视下采用双头加压螺纹钉贴股骨距内固定治疗新鲜股骨颈骨折４２例，随访平均２．５年，其中１６例随访３年以上，骨折愈合率９５．２％，骨折不愈合并股骨头缺血性坏死率４．７６％。认为加压螺纹钉贴股骨距内固定可使钉的受力由较大剪应力变为较大轴向力承受，减少骨折处的剪应力，并加压于骨折端能促进骨折愈合。具有操作简单、进钉准确、创伤小、固定牢靠、并发症少等优点。     

女性膀胱颈部梗阻的诊断与治疗

为探讨女性膀胱颈部梗阻的病因、诊断及治疗方法。总结１９８１年５月～１９９６年６月收治女性膀胱颈部梗阻病例３２例。２９例经手术治疗，其中２例行膀胱颈ＹＶ成形术，２７例经尿道膀胱颈部后唇切除术，效果满意。结果认为，女性膀胱颈部梗阻病因为纤维组织增生和慢性炎症所致；尿流率检查是客观评价排尿状况的指标；膀胱镜检查为可靠的诊断手段；经尿道膀胱颈部后唇切除为有效的治疗方法。     

带旋髂深血管蒂髂骨瓣移植与加压螺钉治疗青壮年股骨颈骨折

本文报告了自１９８５年￣１９９５年间采用带旋髂深血管蒂髂骨瓣移植与加压螺纹钉内固定治疗青壮年囊内型股骨颈骨折２６例。随访时间平均５年５个月。结果，２６例骨折痊愈，骨折愈合率为１００％。骨折愈合时间平均４个月。仅１例骨折愈后后股骨头发生缺血坏死。股骨头缺血坏死率为４％。     

股骨颈骨折粗细双螺钉内固定生物力学研究

股骨颈骨折内固定方法繁多。本文采用一粗一细加压螺纹钉，采用先进电阻应变仪方法，对股骨颈的应力分布规律在中立、外展、内收不同位置上施加50kg荷载压力．通过电阻应变计测定一耗一细两钉所承受拉、压应力优于其它内固定形式。     

A new operational approach for the piriform sinus fistula

It has been well documented that piriform sinus fistulae often cause suppurative thyroditis; however, when a piriform sinus fistula does not present this symptom, making a correct diagnosis is very difficult. We have experienced 11 cases of a piriform sinus fistula. The conventional operational approach was performed in the initial eight patients, among which there were four recurrences in two patients. Therefore, a new operational approach was introduced for the three most recent cases and one recurrent case. First, the existence of the internal orifice of the fistula is confirmed with a laryngoscope, after which a transverse incision on the neck is made and the abscess dissected. The side wall of the piriform sinus is then opened with the help of a laryngoscope and the bottom part of the mucosa of the sinus transected with the internal orifice of the fistula, after which the fistula is removed en bloc with the bottom part of the sinus and abscess cavity. Using this operation, we experienced no complications and there has been no recurrence so far.This paper was presented at the 23rd Annual Meeting of Pacific Association of Pediatric Surgeons, June 1990 in Kona, Hawaii.     

头颈部肿瘤合并糖尿病的围手术期处理

目的探讨头颈部肿瘤合并糖尿病患者围手术期的处理方法.方法从2001年1月～2003年6月我科收治的头颈部肿瘤450例,对其中33例合并糖尿病患者使用胰岛素控制血糖的资料进行分析.结果 28例无并发症发生,切口感染2例,腮腺漏2例,心律失常1例,无围手术期死亡.结论对于合并糖尿病的头颈部肿瘤患者,合理使用胰岛素控制血糖是围手术期处理的主要方法,是安全渡过围手术期的重要保证.     

Diagrammatic recording of head and neck tumours1

The increasing demands of clinical audit have resulted in the need for accurate data collection. The use of tumour maps allows standardization of the records of patients with head and neck cancer, which facilitates collation of data in multicentre studies and makes interdepartmental comparisons more meaningful. The aim of this study was to develop an improved standard set of tumour maps for recording the stage of head and neck tumours. A review of the existing tumour diagrams was performed to identify those anatomical areas that are not adequately represented or where ambiguity exists. The areas where improvements could be made were identified as: (1) the anterior commissure of the larynx; (2) axial and sagittal views of the larynx; (3) the pyriform fossa and cervical oesophagus; (4) the oropharynx and vallecula; (5) the nasal cavity and paranasal sinuses; and (6) cervical nodal involvement. A new set of tumour maps is presented in an attempt to correct some of the limitations of the existing diagrams.     

后路小切口人工全髋关节置换治疗老年人股骨颈骨折

目的:观察后路小切口人工全髋关节置换术(小切口-THA)治疗老年股骨颈骨折的临床效果。方法:本组24例65岁以上股骨颈骨折患者,女13例,男11例;年龄65～78岁,平均73.4岁。均为外伤后股骨颈头下型骨折,位线差,其中Garden分型为Ⅲ型10例,Ⅳ型14例,全部应用后路小切口技术行全髋关节置换术。结果:术后所有病例随访10～24个月,平均13个月。平均手术时间80min,手术切口平均长8.0cm,平均输血300ml,无局部及全身并发症出现。按UCLA(UniversityofCaliforniaLosAngeles)髋关节功能评分标准,本组UCLA评分由术前平均(11.0±3.8)分升至术后平均(24.3±4.5)分(P<0.01)。本组优17例,良4例,一般3例,优良率为87.5%。结论:后路小切口技术具有创伤小、出血少、恢复快的特点,可获得与常规后路相同的治疗效果,尤其适合老年股骨颈骨折患者。
