内镜辅助肋骨-软骨移植重建髁突与同期正颌手术的临床研究

目的 探讨内镜辅助肋骨-软骨移植重建髁突与同期正颌手术治疗严重颞下颌关节病变及牙颌面畸形的效果. 方法 于术前对患者进行临床检查和治疗设计,术中行Le Fort Ⅰ型截骨术、下颌支矢状骨劈开术、髁突等关节区病变的处理、内镜辅助下肋骨-软骨移植和颏成形术,术后进行随访. 结果 2003年9月至2005年12月,于临床应用15例,所有患者同期手术均顺利完成.术中、术后均无严重出血、神经损伤、受区感染等严重并发症发生.术后随访29～52个月,平均31.8个月,所有患者面容均显著改善,关节功能良好,且无关节区疼痛等主观症状,患者对手术疗效满意.术后张口度平均为33.6 mm,侧向运动度为0～6 mm. 结论 选择合适的适应证、设计合理的手术方案,内镜辅助髁突重建同期正颌手术效果较好.     

Allergic fungal sinusitis— A clinico-pathological study

The co-existence of fungal elements in allergic nasal Polyposis, has given rise to a distinct clinical entity known as ‘Allergic fungal sinusitis ’ (AF’S). Many a time, these fungal elements may not be diagnosed pre-operatively by routine diagnostic nasal endoscopy or CT scan of paranasal sinuses, due to the florid presentation of nasal polyps, which usually obscure the underlying fungal pathology. The diagnosis is often made intra-operatively. The post-operative confirmation of AFS is by histopathology, fungal smear, fungal culture, allergic murin study and fungal specific IgE titres. We report a series often such cases done in our institution, which highlight that AFS should be considered as a differential diagnosis in Sinonasal Polyposis cases, for their effective management.     

糖尿病患者超声乳化白内障吸除手术的临床观察

目的:探讨糖尿病患者进行超声乳化白内障吸除联合人工晶状体植入手术的临床效果。方法:50例(61只眼)糖尿病患者(设为A组)和同期163例(174只眼)血糖正常患者(设为B组)接受超声乳化白内障吸除联合人工晶状体植入手术。糖尿病患者手术前通过饮食疗法、口服药物或肌注胰岛素治疗,使空腹血糖降到 10mmol/L以下。术后随访 1～28个月(平均 8.6个月),复查视力、裂隙灯及眼底检查。结果:术后矫正视力≥0.5者,A组为77.1%;B组为80.5%。两组经统计学处理差异无显著性(P>0.05)。两组术中出现后囊破裂及术后发生角膜水肿和前房渗出等并发症的差异无显著性(P>0.05 )。结论:糖尿病患者进行超声乳化白内障吸除手术前只要有效控制血糖,其手术效果与对照组患者相同。但术后血糖的控制仍然十分重要。眼科学报2003;19:98-100。     

Planning for minimally invasive unicompartmental knee arthroplasty

Unicompartmental knee arthroplasty (UKA) is considered the treatment of choice in patients with single compartment arthritis of the knee at early stages or with osteonecrosis limited to one compartment. However, results in the literature are still controversial and it is a technically difficult procedure. The main goal of UKA is to restore the articular space of the afflicted compartment, without influencing the limb alignment. Selection of patients and pre-operative planning are crucial. The necessity to improve functional results and to reduce immobilization of the patients has led to the development of minimally invasive surgery. Applied to UKA, this approach reduces blood loss and surgical time, causes fewer symptomatic postoperative complications, and permits earlier recovery compared to the traditional incision. The shorter incision makes careful pre-operative planning essential. We briefly review the indications for UKA, the pre-operative clinical and radiological assessment, and the surgical procedure.

上胸椎骨折手术治疗方法的探讨

目的 探讨上胸椎骨折的特点及治疗。方法 15例病人按AO分型，A型2例、B型10例、C型3例。均经后路切开复位、脊髓减压、长节段内固定、取髂骨植骨融合术治疗。结果 随访18-24个月，后路长节段固定随访时无一例失败，完全瘫的患者9例中有1例神经功能改善I级．不完全瘫的5例均有Ⅲ级改善，1例无神经损伤。结论 上胸椎骨折损伤严重，后路长节段固定技术是一种合理的有效治疗方法。     

后腹腔镜下肾肿瘤剜除术的临床疗效观察(附5例报告)

目的：探讨后腹腔镜下肾肿瘤剜除术的操作要点及临床价值。方法：采用后腹腔镜下肾肿瘤剜除术治疗肾肿瘤5例，其中肾癌3例，肾错钩瘤2例，瘤体直径1．5～4．0cm。具体方法是：①暴露瘤体和肾动脉；②采用硅胶管牵拉肾动脉，必要时可暂时阻断肾动脉；③于瘤体1cm正常肾组织处用电钩切除瘤体；④采用生物蛋白胶、止血纱布缝合加压处理创面出血。结果：手术均获成功。手术时间150～210min，术中出血80～350ml。术后1～2天肠道功能恢复并可床上活动，1～4天可下床活动。术后住院5～9天，平均7天。结论：后腹腔镜下肾肿瘤剜除术具有创伤小、康复快、安全、住院时间短等优点；对外生性生长、直径小于4cm瘤体，该法可作为首选手术方法。     

Atraumatic retractor for endoscopic surgery

A novel retractor has been designed to achieve atraumatic retraction of the liver and displacement of hollow viscera during endoscopic surgery. The functional section of the instrument, when locked, forms a silicon-covered uniplanar hook which can be deployed for horizontal lift of solid organs such as the liver or be used to engage bowel for displacement from the operative field. Following laboratory testing, the instrument has been evaluated clinically and its ease of deployment and atraumatic nature have been confirmed. It has been found to be particularly effective for elevation of the thick fatty left lobe of the liver during antireflux surgery.     

Stereotactic craniotomy and intraoperative lesion localisation using the Brown-Robert-Wells frame

Summary A simple technique of stereotactic craniotomy and intraoperative lesion localisation that uses the Brown-Robert-Wells (BRW) stereotactic frame is presented. The method optimises craniotomy placement and facilitates localisation of small intracerebral lesions. Using the system, 16 patients have had resection of intracranial neoplasms from deep and/or eloquent areas of the brain with no neurological morbidity.
