烧伤后早期准确削痂治疗深Ⅱ度创面的临床研究

目的探讨烧伤后早期在深Ⅱ度创面削痂手术中使用电动取皮刀准确削痂，对创面进程和愈合质量的影响。方法选择62例深Ⅱ度烧伤患，随机分为二组，均在伤后72h内进行创面削痂手术。术中分别使用电动取皮刀和滚轴取皮刀削痂，观察术中削痂创面出血量、手术所需时间、创面愈合时间及残留肉芽创面的发生事。结果早期对深Ⅱ度创面削痂能降低局部炎症反应。与滚轴取皮刀削痂相比较，用电动取皮刀削痂可降低残留创面的发生率22．6％，缩短病程3．5d。结论电动取皮刀削痂可尽量保存残存的皮肤附件，避免使用滚轴取皮刀削痴过程中经常出现的削痂创面边缘锯齿样切口，也可以避免因术经验、技术的不足所导致的削痴过浅或过深的问题，促进创面愈合和缩短病程，是一种简单易行的削痂方法。

超声手术刀组织切割的实验研究

用国产超声手术刀，在大白兔活体上进行切割实验．并与普通手术刀和高频电刀进行了比较．结果显示超声手术刀的组织切割速度和切缘整齐情况不及普通手术刀，但有一定的止血功能，组织损伤不如高额电刀大，也不引起肌肉收缩，无组织烧焦气味；术后切缘愈合良好．认为超声手术刀更适合于肝、脾等实质性组织的切割．如在操作柄、刀具、仪器性能等方面能进一步改进，应用效果会更好。

Cutting oil dermatitis on guinea pig skin

The effect of repeated exposure of cutting oil on 8 guinea pigs' skin was evaluated by visual scoring for erythema and skin water vapour loss (SVL) measurement over a 6-week period. The visual scores (measuring severity of erythema) and SVL values were significantly higher on skin treated with cutting oils (positive control) compared to untreated skin (negative control) throughout the study period. The scores and SVL values returned to near-baseline values when cutting oil application was stopped. In addition, the effect of 2 "after-work" emollient creams on 8 guinea pigs' skin repeatedly treated with a cutting oil was assessed by similar methods. The visual scores and SVL values of guinea pig skin that was repeatedly treated with the cutting oil and moisturized with "after-work" emollient creams, were significantly higher than negative and positive control guinea pig skin. It appeared that the 2 "after-work" emollient creams do not alleviate the irritant effect of the cutting oil on guinea pig skin. They appeared to aggravate the irritant effect of the cutting oil.     

脑疝复位天幕切开与常规手术治疗重型脑外伤脑疝的临床对照研究

目的　比较脑疝复位天幕裂孔切开与常规去骨瓣手术治疗重型脑外伤引起脑挫裂伤脑水肿、颅内血肿出现脑疝晚期患者的手术效果。方法　共收治重型脑外伤脑疝晚期患者5 6例,分为2组:脑疝复位组31例;常规手术组2 5例。患者术前GCS计分均为3～5分、双瞳孔散大或有不同程度散大,所有患者都经头颅CT扫描确定脑损伤情况。结果　患者术后存活者随访1a ,脑疝复位组:恢复良好/中残1 0例、重残/长期昏迷7例、死亡1 4例(45 %) ;常规手术组:恢复良好/中残1例、重残/长期昏迷3例、死亡2 1例(84 %) (P <0 .0 5 )。脑疝复位组术后大脑后动脉梗死、应激性溃疡、脑积水发生率明显低于常规手术组(P均<0 .0 5 )。结论　脑疝复位天幕裂孔切开治疗重型脑外伤引起脑挫裂伤脑水肿、颅内血肿出现脑疝晚期患者疗效明显优于常规去骨瓣手术。

Digital cutting guide and endoscopically-assisted vertical ramus osteotomy to treat condylar osteochondroma: a long-term study

We have introduced an effective treatment for mandibular condylar osteochondroma with a digital cutting guide and endoscopically-assisted vertical ramus osteotomy (VRO). Eleven patients with unilateral condylar osteochondroma, who did not require orthognathic surgery or had less than 3 mm deviation of the chin and a stable occlusion, were treated during the period April 2013–January 2017 with a digital cutting guide and endoscopically-assisted VRO. Clinical data collected included the occlusion, facial contour, and maximum mouth opening (MMO). Computed tomographic (CT) scans were taken before and after operation. Two patients also had additional shaping of the mandibular contour. The pathological diagnosis was confirmed to be osteochondroma in all cases. A mean (range) 19 (12–40) months of follow-up for all 11 cases showed stable postoperative occlusion and facial aesthetics. There were no functional disturbances, recurrence, or condylar absorption. VRO is an alternative to orthognathic surgery for patients with osteochondroma who do not have severe malocclusions. The digital cutting guide and endoscopically-assisted VRO make it possible to achieve precise resection of the tumour and maintain the occlusion with minimal invasion.
