【Abstract】 Objective To investigate the method and effectiveness of reverse anterolateral thigh flap and muscle flap for repair of wound defects with exposed tibia in the proximal-middle leg. Methods Between October 2005 and April 2010, 16 patients with wound defects with exposed tibia in the proximal-middle leg were treated with reverse anterolateral thigh flap and muscle flap. There were 10 males and 6 females, aged from 16 to 52 years. Injury was caused by traffic accident in 11 cases and by crushing in 5 cases. The disease duration of 1-6 hours (mean, 3 hours) in 10 patients and 6-14 days (mean, 10 days) in 6 patients, who underwent tibial fracture plate fixation in other hospitals. The size of wound ranged from 13 cm × 7 cm to 20 cm × 13 cm. The size of the flap ranged from 16 cm × 10 cm to 23 cm × 15 cm. The donor sites were covered with splite thickness skin grafts. Results Infection occurred in 2 flaps at 5-7 days and was cured after 1 week of dressing change; the other flaps survived and the wounds healed by first intention. The incisions healed well and the skin grafts survived at the donor sites. All cases were followed up 10-23 months (mean, 18 months). The appearance of the flap was slightly overstaffed, but the color and texture were satisfactory. All fractures healed at 8-10 months after operation. Conclusion It is effective to repair wound defects with exposed tibia in the proximal-middle leg with reverse anterolateral thigh flap and muscle flap.
目的 观察独用内镜下手术以及联合等离子低温射频治疗外耳道乳头状瘤的疗效。 方法 2006年7月－2010年7月，随机将收治的45例外耳道乳头状瘤患者（150只耳）分组，比较独用内镜下手术组（A组）以及联合等离子低温射频组（B组）治疗外耳道乳头状瘤的疗效。 结果 患者均术后成功随访1～3年，48只患耳无复发及恶变，2只患耳3个月后复发。 结论 内镜下手术联合等离子低温射频治疗外耳道乳头状瘤具有微创，手术彻底有效，防止复发的优点，值得临床广泛应用。
Objective To investigate the cl inical appl ication of grafting with bioactive glass (BG) and autologousbone marrow for defect after resection and curettage of benign bone neoplasm. Methods From January 2004 to May2007, 34 patients with bone defects were repaired. There were 21 males and 13 females with a mean age of 25.6 years (8 to 56 years). There were 14 cases of simple bone cysts, 6 cases of fibrous dysplasia, 3 cases of osteoid osteoma, 4 cases of non-ossifying fibroma, 2 cases of enchondroma and 3 cases of giant cell tumor of bone. Tumor sizes varied from 2.0 cm × 1.5 cm × 1.0 cm to 9.0 cm × 3.0 cm × 2.5 cm. Benign bone neuplasm was removed thoroughly with a curet or osteotome, bone defects ranged from 3.0 cm × 2.0 cm × 1.5 cm to 11.0 cm × 3.5 cm × 3.0 cm, which was closed-up with the mixtures of BG and autogenous red bone marrow. Six cases of pathologic fracture were fixed with steel plate or intramedullary nail. The postoperative systemic and local reactions were observed, and the regular X-ray examinations were performed to observe the bone heal ing. Results All the patients had good wound heal ing after operation. There was no yellow effusion nor white crystal and skin rash appeared around wound, indicating no allergic reaction occurred. A follow-up of 1 to 4 years (mean 24.6 months) showed satisfactory heal ing without compl ications. At averaged 16 weeks after operation, patients with bone tumor in lower l imbs resumed walking independently and those with bone tumor in upper l imbs resumed holding object. There was no tumor recurrence during follow-up. Radiographically, the interface between the implanted bone and host bone became fuzzy 1 month after implantation. Two months after operation, the BG was absorbed gradually, new bone formation could be seen in the defects. Four months after operation, implanted bone and host bone merged together, bone density increased. Six to ten months after operation, the majority of the implanted BG was absorbed and substituted for new bone, bone remodel ing was establ ished. Conclusion BG may boast both bone conductive and bone inductive activities. The combined grafting with BG and autologous bone marrow appears to be minimally invasive treatment to repair bone defects of benign bone neuplasm, with rare compl ications and no significant reverse reaction, and could repair bone defects completely.
【摘要】 目的 探讨手术治疗鼻气道狭窄对阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome，OSAHS)患者的疗效。 方法 2008年2月-2010年2月，对300例OSAHS患者行鼻内镜鼻腔手术治疗，比较患者手术前后打鼾程度、嗜睡程度和鼾声评分。 结果 手术治疗鼻气道狭窄后患者嗜睡评分及鼾声评分平均值均小于术前，差异有统计学意义(Plt;0.05)，手术有效率88.67%，手术并发症发生率0.67%，为鼻中隔穿孔、鼻腔粘连。 结论 手术治疗鼻气道狭窄是治疗因鼻气道狭窄所致OSAHS的一种有效方法。【Abstract】 Objective To explore the therapeutic effect of the surgery of narrow nasal cavity on the obstructive sleep apnea hypopnea syndrome (OSAHS). Methods A total of 300 patients with OSAHS from February 2008 to February 2010 underwent the surgery of narrow nasal cavity and the pre- and post-operative Epworth sleepiness scale and snore scale were analyzed. Results After the surgery of narrow nasal cavity, snore degree, somnolence scale and snore scale decreased compared with those before the operation (Plt;0.05). The effective rate of the surgery was 88.67% and the rate of operative complication was 0.67%. Conclusion The surgery of narrow nasal cavity is effective for the patients with OSAHS caused by narrow nasal cauity.
