OBJECTIVETo explore the clinical effect of the method by using an expanded post-auricular skin flap combined with autologous rib cartilage framework for correction of concha-type microtia.

METHODSThe operation were performed in three stages. The expander was implanted under post-auricular skin at the first stage and expanded skin flap was formed. At the second stage, the expander was taken out and the expanded skin flap was transferred with autologous rib cartilage framework and skin graft for correction of microtia. At the third stage, the reconstructed ear was revised and new concha was formed.

RESULTSFrom August 2008 to August 2011, 108 cases with 113 concha-type microtia were corrected by this method. All patients healed primarily and were followed up for 6 months to 3 years. The reconstructed ears had a good appearance and position, and were symmetric to ear on the healthy sides.

CONCLUSIONSUsing expanded post-auricular skin flap combined with autologous rib cartilage framework is a reliable method for concha-type microtia.

OBJECTIVETo investigate a novel method for the reconstruction of large vermilion defects.

METHODSBased on the size and shape of the defects, a buccinator myomucosal flap pedicled with the junction of buccinator and orbicularis oris in the oral commisure was designed and rotated to reconstruct the large vermilion defects. The upper bound of the flap is at least 1 cm away from the stensen's duct. The width is about 2.5-3.0 cm, and the length is as far as to arrive the raphe pterygomancibularis. The donate site is directly closed primarily. There is no need for secondary pedicle division.

RESULTSFrom July 2003 to April 2013, 14 cases with large vermilion defects was reconstructed with this method. No flap necrosis occurred with primary healing. 5 cases were followed up with an average follow up period of 1 year (0.5-3 years). The apprearance and function of the reconstructed vermilion were satisfactory without any apparent donor site defect. The patients were satisfied with both the functional and cosmetic results.

CONCLUSIONThe buccinator myomucosal flap is a simple and ideal method for reconstruction of large vermilion defects, especially for the defects closed to the commisure.

OBJECTIVETo investigate the characteristics and incidence of the thoracic deformities in patients with microtia.

METHODSIn Plastic Surgery Hospital, we conducted a retrospective study of the clinical and radiographical data of 300 patients with microtia from March 2013 to October 2014. Pearson χ2 test was used to analyze the relationship among deformities of ribs and spine, as well as microtia.

RESULTSA total of 78 (26.0%) patients were documented with rib deformities, 26 patients (8.7%) had spinal deformities, and 17 patients (5.7% )had both. The incidence of rib deformities in microtia I, II, and III was 7.1% (2/28), 26.7% (62/232) and 35.0% (14/40) respectively. The incidence of spinal deformities in microtia I, II, and III was 3.6% (1/28), 6.5% (15/232) and 25.0% (10/40 respectively. The patients with microtia III were found to have a higher incidence of ribs and spinal deformities than those with microtia II, patients with microtia II were found to have a higher incidence of ribs and spinal deformities than those with microtia I (P < 0.05).

CONCLUSIONSThe incidence of ribs and spinal deformities is high in patients with microtia. The poorer one auricle developed, the higher the incidence of thoracic deformities.

Objective:To explore the technique of two-flap in ear reconstruction.Method:Quantitative tissue expansions were used in the mastoid area in the first stage.After the final injection,there was 1 month of sustaining time.Expanded skin flap and unexpanded fascia flap were designed in the second stage,so thetwo-flaptechnique was used in the ear reconstruction.From January 2004 to December 2008,1 427 patients of microtia were treated using two-flap technque.Result:The expanded skin flap could show the fine structures of the reconstructed ears.The reconstructed ears had vivid cranioauricular angle after using the unexpanded fascia flap.Conclusion: Two-flap method was easily manipulated and the complications were rare.The reconstructed ears had lucid and three-dimensional contour.

OBJECTIVETo investigate the feasibility of ear reconstruction using local expanded scarred skin flap.

METHODWe used local postauricular expanded scar skin flaps to reconstruct external ear in 24 patients.

RESULTSOf these cases, 22 flaps survived completely. In 2 patients, the cartilage framework exposed over the upper pole of helix region because of undue tension in suturing the tissue edges. One year's follow-up revealed satisfactory results.

CONCLUSIONUsing the expanded scarred skin flap for ear reconstruction is practical and effective, when there's no normal skin available in the local area.

OBJECTIVELow hairline is one of the most troublesome problem in auricle reconstruction. There was no satisfactory way to manage the problem. This article discuss surgical depilation to deal with this problem and reconstructed auricle.

METHODSAccording to the degree of the low hairline, Postaurical scalp was expanded and part of the lower follicles within the dermal were removed, or postaurical scalp that part of lower follicles and dermal had been removed was expanded and covered skeleton of ear with this expanded skin to reconstructed auricle.

RESULTSAuricles were reconstructed with this method in 152 lowhairline microtial cases, the result was very satisfactory.

CONCLUSIONThis procedure is an effective way to deal with low hairline in reconstructing auricle.

Objective To measure and compare the cerebral blood flow(CBF)of children with autism spectrum disorder(ASD),global developmental delay(GDD),and ASD with GDD groups via arterial spin labeling(ASL)technique,and to evaluate the diag-nostic value of CBF values.Methods ASL images of ASD,GDD,and ASD with GDD groups of children were firstly acquired,and the CBF values of frontal lobe,temporal lobe,parietal lobe,occipital lobe,striatum and thalamus region of interest(ROI)were fur-ther measured,respectively.One-way analysis of variance or Kruskal-Wallis H test was used to compare the differences in CBF values among these three groups,and the receiver operating characteristic(ROC)curve was used to analyze the efficacy of CBF values in distinguishing ASD with GDD from without GDD.Results ASD with GDD had significantly lower CBF values in the left and right frontal lobes than those with ASD or GDD alone,and the differences were statistically significant(P<0.05).The CBF values in the left and right frontal lobes effectively distinguished ASD with GDD from without GDD[area under the curve(AUC)>0.7].Conclusion ASL technique can noninvasively assess CBF in children with or without GDD,helping to understand the pathophysiology of ASD with GDD and improving diagnostic accuracy.

Radiation-induced lung injury is a common complication of thoracic malignant tumor radiotherapy and severe nuclear accident injury. Currently, there is no effective treatment on this injury. Mesenchymal stem cells (MSCs) are a group of cells with multi-directional differentiation potential and they can protect lung tissue from radiation damage by homing to the injured site and differentiating to the damaged tissues, secreting cytokines and immune regulation. Further, the genetically modifying mesenchymal stem cells have not only the main characteristics of MSCs, but also can efficiently and stably express or knock down a certain of target genes, thereby enhancing or reducing the sensitivity of mesenchymal stem cells to various physiological stimulus and enhancing its therapeutic effect in radiation-induced lung injury, providing new ideas and new strategies for clinical treatment. This paper reviewed the relevant research progress in recent years.
