目的:评价作者改进的计算机辅助眶鼻窦重建术治疗复发性眶鼻窦黏液囊肿的临床效果。方法:回顾性分析河南省人民医院2008年7月至2018年1月接受改进的计算机辅助眶鼻窦重建术治疗复发性眶鼻窦黏液囊肿45例的临床资料。观察手术效果。术后随访25~44个月。结果:所有患者术后视力(BCVA,logMAR)优于术前(t=7.665,P<0.05),眼球突出度低于术前(t=8.871,P<0.05);鼻窦内引流通道均通畅,无复发,无感染或异物排斥等不良反应。CT显示均得到较好的眶鼻解剖重建,复视现象消失,眼球的位置、运动功能及外观均恢复正常。结论:改进的计算机辅助眶鼻窦重建术是一种较好治疗复发性眶鼻窦黏液囊肿的方法。     

Laparoscopic-Assisted Vesicocalicostomy for Severe Pelvi-Ureteral Stricture Disease

A 39-year-old female previously treated with shock wave lithotripsy developed extensive ureteral stricture disease. After 2 unsuccessful attempts at retrograde balloon dilatation, she was evaluated at our center for further management. Successful reconstruction was performed with laparoscopic-assisted vesicocalicostomy.     

Biomechanical evaluation of caudally and buccally screwed customised reconstruction plates for lateral segmental defects of mandible

The aim of this study was to compare locking reconstruction plates with caudobuccally screwed custom mandibular reconstruction plates in bridging lateral mandibular segmental defects. The in vitro study was conducted on 13 polyurethane mandibles. A total of 7 mandibles with lateral segmental defects were bridged with locking reconstruction plates in group I, 6 mandibles with the same standard defect were bridged with caudobuccally screwed customised reconstruction plates in group II. Mean yield displacement, yield load, and displacement at 80 N (Newtons), 100 N, 200 N, 300 N loading were compared among the 2 groups. The mean (SD) displacement for Group I was 11.27 (3.6) mm, Group II was 21.08 (2.5) mm. Group II had significantly greater (p=0.0001) displacement when compared with Group I. The mean (SD) force before failure for Group I was 638.4 N (127.2), Group II was 1398. 3 N (162.7). Group II withstood significantly greater force than Group I (p=0.0001). The study reveals that the caudobuccally screwed custom reconstruction plates can significantly enhance yield load as preserving the preoperative shape of the face and mandible.     

Immediate Continence Rates in RALRP: A Comparison of Three Techniques

Methods:We retrospectively analyzed the patients who underwent RALRP for localized prostate cancer by a single surgeon in our clinic from January 1, 2009–February 1, 2016. Continence was defined as no leakage or use of a safety pad for minimal leakage. The main outcome measure was continence at postoperative week 1 and months 1, 6, and 12.Results:Between 2009 and 2016, 239 patients underwent RALRP for localized prostate disease. Seventy-four patients underwent a standard approach (group 1), 88 had posterior reconstruction (group 2), and 77 had posterior reconstruction with total anatomic restoration (group 3). After 1 week, 24.3% of the patients in group 1 (18/74), 31.8% in group 2 (28/88), and 45.8% in group 3 (33/72) were continent (P = .02). One month after the surgery, continence rates for groups 1, 2, and 3 were 56.7, 67, and 75%, respectively (0.065). After 6 and 12 months, continence rates for groups 1, 2, and 3 were 72.9 and 87.8%, 81.8 and 89.7%, and 84.7 and 91.6%, respectively (P = .178 and .7484).Conclusion:Anatomic restoration improves continence rates in the early period after RALRP. Even though other parameters were higher in the total restoration group, immediate continence (at 1 week) was significantly better.     

Island Pectoralis Major Myocutaneous Flap: An Indian Perspective

The aim of this study is to conceive a method of raising an island PMMC flap, so as to circumvent its drawbacks of bulk, flap length and the difficulty of developing this flap in female patients. And to consider island PMMC flap as a viable reconstructive option in head and neck surgeries, especially in peripheral centres. Ours is an experimental case series. The study was done at Sri Devaraj URS Medical college, Tamaka, Kolar. Between 2009 and 2010, head and neck reconstruction was performed using this method in 20 patients who had oral cancer (18), carcinoma supraglottis (1) and mucoepidermoid carcinoma parotid (1). The patients age ranged from 16 to 75 years, and there were 15 women and 5 men. Nineteen of our patients underwent primary surgery and one patient was operated for residual disease. In (16) patient, island pmmc flap was used for intra oral closure. In (4) patients the flap was spiraled for providing skin cover. Four patients developed complications. Three were minor complications of margin necrosis and wound dehiscence, which were managed conservatively. One patient developed orocutaneous fistula, which required secondary suturing. None of our patients had a total necrosis of the flap. Island PMMC flap is still a very useful and viable option for reconstruction in head and neck surgeries, especially in lateral gingivo buccal tumours and other head and neck tumours. In institutions where microvascular expertise is not available, island PMMC flap can be an alternative with results comparable to that of free tissue transfer.     

小儿输尿管膨出症的治疗

目的探讨各种方法治疗输尿管膨出症的疗效,寻找影响预后的有关因素。方法 31例输尿管膨出症,男4例,女27例;左侧15例,右侧12例,双侧4例。其中单一输尿管膨出2例,重肾并输尿管膨出29例。VCU检查18例,3例发现中—重度反流,31例均行超声和IVU及CT检查。结果术后随访0.5～3 a,2例单一输尿管膨出症行膨出切除输尿管膀胱再植术,29例重肾中,4例经膀胱行输尿管膨出切除输尿管膀胱再植术。3例中—重度反流,2例行输尿管膨出切除加上半肾切除术,1例行上半肾切除术,术后因反流持续存在,需再次手术;其余22例均行上半肾切除术,术后2例因严重尿路感染行输尿管残端切除术。结论输尿管膨出的治疗应根据输尿管膨出的类型、肾功能、有无反流决定手术方式,对于大多数重肾,单纯上半肾切除预后良好,若术前VCU检查有中—重度返流,应行完全重建术。
