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 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.

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 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.

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.

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 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 the "two-flap" technique was used in the ear reconstruction. From January 2004 to December 2008, 1427 patients of microtia were treated using "two-flap" technique. 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.

Objective: To explore the curative effect of ultra-delicate split-thickness skin graft in continuity with full-thickness skin flap combined with Z-plasty for correction of cryptotia. Methods: Four cases (six ears) were corrected by ultra-delicate split-thickness skin graft in continuity with full-thickness skin flap combined with Z-plasty method from 2016 to 2017. Following ear release, the flap is rotated into the defect and donor site covered by a razor-thin graft raised in continuity with the flap, the posterior flap was advanced and sutured with Z-plasty. Results: All corrected auricles four cases (six ears) were followed up from 3 months to 1 year and abtained satisfactory and stable appearance. Conclusions The shape of auricle is natural and satisfactory after operation. The method is simple and no skin grafting is needed. The adhesion of the hidden muscles and cartilages were sufficiently released.

Objective: To investigate treatment and outcome of rib cartilage framework in ear reconstruction. Methods: 12 cases of rib cartilage framework infection in ear reconstruction were retrospectively analysed in the latest four years. Lab examination results showed that staphylococcus aureus were found in 5 cases, coagulase negative staphylococcus in 3 cases, Klebsiella pneumonia in 2 cases, aeromonas hydrophila in 1 case and no bacteria were found in 1 case with regular culture. Debridement, systemic antibiotic therapy, saline irrigations and unobstructed drainage were utilized to treat the infection. Results: The average duration of dressing change was 35 days in 12 cases (12-67 days), of which six cases were cured leaving no obvious or mild change of cartilage framework. Cartilage framework was totally damaged by infection in one case, so the framework had to be removed and debridement was then carried out to control infection. Secondary repair should be taken at least 6 months later. In the rest 5 cases, frameworks were taken out in the early stage of infection. The infected portion of the cartilage was removed and the healthy part was buried subcutaneously in the chest. The expanded postauricular flap and fascia were smoothened. Secondary repair should be performed after 6 months. Conclusions Effective debridement, irrigations and drainage can be used to control infection of cartilage framework and maintain normal contour and structure of reconstructed auricle. With regards to severe infection, framework should be removed as early as possible and infected portion of cartilage should be cleared out, while healthy part could be used for secondary reconstruction of auricular contour after complete control of infection.

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.
