自体脂肪移植矫正凹陷性瘢痕的技巧

目的探讨采用自体脂肪移植矫正凹陷性瘢痕的效果与注射移植技巧。方法自2009年7月至2014年3月,共接诊21例（24处）凹陷性瘢痕患者。移植前1d以生理盐水注射法评估注射量。用注射针头往返穿刺松解受区瘢痕粘连,然后行多层面、多隧道自体脂肪注射移植。结果21例（24处）患者注射盐酸肾上腺素生理盐水5～40ml,自体脂肪注射移植量为6～48ml,注射后凹陷畸形得到矫正,局部稍隆起;1个月后有部分吸收,隆起消退,注射处与周围皮面相平;6个月后,局部基本平坦,患者均满意。所有患者均未出现硬结、囊肿、感染等并发症。结论只要患者病情适合,注射方法得当,自体脂肪移植是矫正凹陷性瘢痕的良好方法。     

Cross-sectional area of the abdomen predicts complication incidence in patients undergoing sternal reconstruction

Background

Sternal reconstruction with vascularized flaps is central to the management of sternal wound infections and mediastinitis but carries a high risk of complications. There is a need to identify reliable predictors of complication risk to help inform patients and clinicians in preparation for surgery. Unfortunately, body mass index and serum albumin may not be reliable predictors of complication rates. Analytic morphomics provides a robust quantitative method to measure patients' obesity as it pertains to their risk of complications in undergoing sternal reconstruction.

Methods

We identified 34 patients with preoperative computed tomography scans of the abdomen from a cohort of sternal reconstructions performed between 1997 and 2010. Using semiautomated analytic morphomics, we identified the patients' skin and fascia layers between the ninth and 12th thoracic spine levels; from these landmarks, we calculated morphomic measurements of the patients' abdomens, including their total body cross sectional area and the cross sectional area of their subcutaneous fat. We obtained the incidence of complications from chart review and correlated the incidence of complications (including seroma, hematoma, recurrent wounds, mediastinitis, tracheostomy, and death) with patients' morphomic measurements.

Results

Sixty-two percent of patients (n = 21) suffered complications after their operation. Those who suffered from complications, relative to those who did not have complications, had increased visceral fat area (12,547.2 mm²versus 6569.9 mm², P = 0.0080), subcutaneous fat area (16,520.2 mm²versus 8020.1 mm², P = 0.0036), total body area (91,028.6 mm²versus 67,506.5 mm², P = 0.0022), fascia area (69,238.4 mm²versus 56,730.9 mm², P = 0.0118), total body circumference (1101.8 mm versus 950.2 mm, P = 0.0017), and fascia circumference (967.5 mm versus 868.1 mm, P = 0.0077). We also demonstrated a significant positive correlation between the previously mentioned morphomic measurements and the incidence of complications in multivariate logistic regression models, with odds ratios ranging from 1.19–3.10 (P values ranging from 0.010–0.022).

Conclusions

Increases in abdominal morphomic measurements correlate strongly with the incidence of complications in patients undergoing sternal reconstruction. This finding may influence preoperative risk stratification and surgical decision making in this patient population.     

Oral Verrucous Hyperplasia: A Case Report

Oral verrucous hyperplasia is a whitish or pinkinsh elevated pre malignant lesion which occurs rarely. Its is also considered to be an early form of verrucous carcinoma. We have reported a case of verrucous hyperplasia which was diagnosed and treated with buccal fat pad as graft.     

下睑缘切口皮瓣延伸肌皮瓣法切除睑袋的效果观察

目的探讨下睑缘切口皮瓣延伸肌皮瓣法切除睑袋的临床效果。方法于下睑缘睫毛根下1mm处平行下睑缘设计切口,由内眦至外眦,经外眦处与水平线呈15°～30°处向外下方斜行切开3～7mm,先向下皮下剥离约5mm,再切开眼轮匝肌,形成上方为皮瓣下方为肌皮瓣的复合瓣,复合瓣后方的眶隔脂肪充分显露,以眶下缘平面为基准,直视下切除疝出的眶隔脂肪,对有“泪槽”凹陷者将眶隔脂肪转移填充凹陷至下睑平整,最后,扇形切除多余的皮肤和肌肉,间断缝合切口。按照睑袋切除术后满意度标准,对术后效果进行评价,并记录各种并发症的发生情况。结果术后随访1～12个月,按照术后满意度评定标准,患者的满意率82％（262／319）;基本满意率14％（45／319）;不满意率4％（12／319）。本组中43例出现并发症,如轻度复视、轻度睑外翻、血肿等,均经术后7d至3个月逐渐恢复。但14例血肿患者中,有2例在术后6个月行手术切除血肿后,外观改善;6例术后7d拆线时出现切口裂开,经医用胶水粘合后恢复。所有患者术后睑袋畸形均得到不同程度地矫正,下睑皮肤皱纹明显减少或消失,瘢痕不显,无严重的并发症发生。结论采用下睑缘切口皮瓣延伸肌皮瓣法修复中老年人下睑皮肤松弛,效果良好,并发症少,值得临床推广应用。     

棕色脂肪摄取18F-FDG的影像学表现（附6例报告）

目的：分析和探讨棕色脂肪（BAT）摄取18F-FDG的影像学图像特点。方法：回顾性分析2005年11月-2007年2月间所有。SF-FDGPET／CT显像病例，根据判断标准选择BAT显影病例。结果：493例中有6例BAT显影（6／493，1．2％），男1例，女5例；BAT显影以对称性分布在颈部、锁骨上、腋下和胸椎旁为主，SUVmax在1．4～9．2之间；5例患者（5，6，83．3％）BAT于寒冷季节显影：1例患者两次显像中一次出现BAT显影，而另一次未出现；所有病例延迟显像发现BAT分布部位及放射性浓聚程度无明显变化，其中4例体重指数（BMI）较低。结论：BAT摄取18F—FDG的显影分布形式多种多样，PET诊断医师应熟悉和掌握BAT图像特点，以降低对BAT显影的假阳性诊断率。
