Wang T, Zhi J, Pan B, Jiang H. The impact of national health insurance on the cost of auricular reconstruction with skin expansion for microtia in China: A single-center retrospective study based on 1290 surgeries. J Plast Reconstr Aesthet Surg 2024; 94:62-71. [PMID: 38763056 DOI: 10.1016/j.bjps.2024.04.067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Accepted: 04/25/2024] [Indexed: 05/21/2024]
Abstract
BACKGROUND Congenital microtia presents challenges that encompass physical disabilities and psychosocial distress. It is reported that people with low income have a higher possibility of giving birth to babies with congenital malformations. At the end of June 2023, auricular reconstruction was partially incorporated into national health insurance in our hospital. METHODS Briefly, 1290 surgeries, including stage-I and stage-II auricular reconstruction with tissue expansion were performed in 2023, involving 779 patients. Patient data, including age, sex, length of stay, residence, and costs, were retrieved from the electronic medical record system. The final cost before and after health insurance coverage, as well as the medical insurance reimbursement ratio in each province and municipality were statistically analyzed. RESULTS Following insurance coverage, a significant increase in the number of surgeries was observed (514 [39.84%] vs. 776 [60.16%], χ2 = 45.99, p = 0.000), with notable reductions in out-of-pocket costs for unilateral and bilateral stage-I and -II auricular reconstructions ($3915.01 vs. $6645.28, p < 0.05; $11546.80 vs. $5198.08, p < 0.05). Disparities in reimbursement rates across regions were evident, but showed no correlation to the local GDP per capita. There was a positive correlation between the length of stay and inpatient cost. Patient's age was not related to the inpatient cost, but to the length of stay. CONCLUSION The health insurance coverage for microtia treatment significantly alleviated financial burdens on the patients' family and increased the number of auricular reconstruction surgeries. These findings underscore the critical role of insurance coverage in enhancing healthcare accessibility and affordability for patients with congenital microtia.

Abstract
BACKGROUND Lobule transposition, a common procedure in auricle reconstruction, has been successfully performed over the past few decades. However, the transposition methods for unilateral microtia with evident asymmetry of bilateral earlobe positions still remain a challenge. The objective of this study was to investigate the application of prograde transposition for anteriorly low-set earlobes. METHOD A total of 25 patients with lobule-type microtia with anteriorly low-set residual earlobe underwent prograde transposition during auricle reconstruction between 2020 and 2022. The post-operative earlobe aesthetic assessment and patient satisfaction were evaluated, and the data on any complications that occurred when followed-up were collected. This study provides a comprehensive analysis and summary of the techniques used in earlobe transposition for auricular reconstruction. RESULTS The patients with evident asymmetry between the residual and healthy earlobes were usually concomitant with hemifacial microsomia and the residual ear was located in the anterior and lower region. No instances of flap necrosis, hematoma, or wound dehiscence were observed following auricular reconstruction. The mean aesthetic score of the auricle was 3.52, with 23 patients attaining good or excellent aesthetic outcomes. The mean Visual Analog Scale satisfaction score was 3.68, with 24 patients reporting relative satisfaction or satisfaction. CONCLUSION The prograde transposition of anteriorly low-set earlobe in lobule-type microtia reconstruction can effectively ensure adequate blood supply, enhance aesthetic appearance, and significantly improve patient satisfaction.

Abstract
OBJECTIVES The primary problem in simultaneous bilateral auricle reconstruction is the fragility of the reconstructed ear structure. Postoperative pressure is strictly prohibited to ensure the operation's effectiveness. The study aimed to summarize the experience of perioperative postural management in simultaneous bilateral auricular reconstruction. METHOD This study summarizes the experience of perioperative postural management, providing preoperative sleeping posture adaptability training, neck movement training, standardization of the head position angles and the head suspension time in surgery, using protective headrests, paying attention to the transfer and handover procedures, and using specially designed pillows. RESULTS The comprehensive nursing approach in simultaneous bilateral auricular reconstruction significantly reduced complications, improved patient comfort, and optimized postoperative adaptation. Preoperative posture training, standardized intraoperative head positions, and vigilant postoperative care played pivotal roles, demonstrating positive outcomes in 46 cases. DISCUSSION Perioperative position management can reduce the risk of complications and pressure injuries, improving patients' postoperative comfort, emotional state, tolerance, and adaptability. CONCLUSION All ears were viable and in good shape after long-term follow-up. The experiences discussed in this study can be broadly applied to technically mature ear reconstruction teams.

Abstract
Auricular reconstruction remains a challenging procedure, requiring a high degree of manual dexterity and attention to detail in order to reconstruct the complex three-dimensional geometry of the ear successfully. Most techniques will rely on autologous cartilage for auricular framework fabrication, carrying a risk of donor and recipient site morbidity. The aim of this report is to investigate the complications and aesthetic outcomes associated with autologous cartilage harvest in auricular reconstruction. A systematic review protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) and reported in accordance with the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses. Comprehensive electronic search strategies for four databases were developed. Studies were screened according to the inclusion and exclusion criteria by two independent reviewers. The literature search identified 7171 articles. Filtering for relevance and duplication reduced the number of articles to 52. A total of 12,215 patients underwent auricular reconstruction utilising autologous cartilage. Indications included 11,696 patients due to microtia, 334 patients due to burns or trauma, 70 patients due to constricted ears, and 115 patients due to prominent ears. The most commonly reported donor site complications included chest wall deformities (n = 159). The most commonly reported recipient site complications included hypertrophic or keloid scars (n = 279), haematoma (n = 155), tissue expander exposure (n = 111), cartilage or framework exposure (n = 122), and cartilage framework deformation or resorption (n = 50). Although a challenging procedure, auricular reconstruction utilising autologous cartilage is possible. Exceptional aesthetic results can be achieved when performed by a skilled surgeon on appropriately selected individuals. However, the potential risks and complications associated with the procedure should be discussed with the patient and family beforehand.

Abstract
PURPOSE In recent years, 3D printing technology has been employed as a production method that builds materials layer upon layer, providing notable advantages in terms of individual customization and production efficiency. Autologous costal cartilage ear reconstruction has seen substantial changes due to 3D printing technology. In this context, this research evaluated the prospects and applications of 3D printing in ear reconstruction education, preoperative planning and simulation, the production of intraoperative guide plates, and other related areas. METHODOLOGY All articles eligible for consideration were sourced through a comprehensive search of PubMed, the Cochrane Library, EMBASE, and Web of Science from inception to May 22, 2023. Two reviewers extracted data on the manufacturing process and interventions. The Cochrane risk of bias tool and Newcastle-Ottawa scale were used to assess the quality of the research. Database searching yielded 283 records, of which 24 articles were selected for qualitative analysis. RESULTS The utilization of 3D printing is becoming increasingly widespread in autogenous costal cartilage ear reconstruction, from education to the application of preoperative design and intraoperative guide plates production, possessing a substantial influence on surgical training, the enhancement of surgical effects, complications reduction, and so forth. CONCLUSION This study sought to determine the application value and further development potential of 3D printing in autologous costal cartilage ear reconstruction. However, there is a lack of conclusive evidence on its effectiveness when compared to conventional strategies because of the limited number of cohort studies and randomized controlled trials. Simultaneously, the evaluation of the effect lacks objective and quantitative evaluation criteria, with most of them being emotional sentiments and ratings, making it difficult to execute a quantitative synthetic analysis. It is hoped that more large-scale comparative studies will be undertaken, and an objective and standard effect evaluation system will be implemented in the future.

Abstract
SUMMARY Ear framework handcrafting simulation using costal cartilage models is crucially important for ear reconstruction surgery education. Fabrication of proper models that are mechanically and structurally comparable to their native counterparts is an unmet challenge. The authors developed structure and mechanical performance biomimetic costal cartilage models for practicing and simulating handcrafting of ear frameworks. High-tensile silicone and three-dimensional techniques were used to fabricate biomimetic models. The models well-replicated the three-dimensional structure of human costal cartilage. Comprehensive mechanical tests showed that high-tensile silicone models had stiffness, hardness, and suture retention ability similar to those of their native counterparts, and they were distinctly superior to commonly used materials for costal cartilage simulation. This model satisfied surgeons and contributed to creation of outstanding ear frameworks. The recreated models were used in ear framework handcrafting workshops. Novices' surgical simulation performance with different models was compared and analyzed. People who used high-tensile silicone models have greater progress and confidence after training. Using high-tensile silicone costal cartilage models is an excellent choice for practicing and simulating the fabrication of ear frameworks manually. The models benefit practitioners and students in practicing handcrafting ear frameworks and surgical skills.

Abstract
Microtia is a congenital disorder that manifests as a malformation of the external ear leading to psychosocial problems in affected children. Here, we present a tissue-engineered treatment approach based on a bioprinted autologous auricular cartilage construct (EarCartilage) combined with a bioengineered human pigmented and prevascularized dermo-epidermal skin substitute (EarSkin) tested in immunocompromised rats. We confirmed that human-engineered blood capillaries of EarSkin connected to the recipient's vasculature within 1 week, enabling rapid blood perfusion and epidermal maturation. Bioengineered EarSkin displayed a stratified epidermis containing mature keratinocytes and melanocytes. The latter resided within the basal layer of the epidermis and efficiently restored the skin color. Further, in vivo tests demonstrated favorable mechanical stability of EarCartilage along with enhanced extracellular matrix deposition. In conclusion, EarCartilage combined with EarSkin represents a novel approach for the treatment of microtia with the potential to circumvent existing limitations and improve the aesthetic outcome of microtia reconstruction.

Abstract
Introduction: Auricular reconstruction techniques most frequently utilize either autologous costal cartilage or alloplastic porous polyethylene (PPE) implant. Objectives: To compare the aesthetic outcomes, number of surgeries, and complications in children who underwent microtia reconstruction with either rib or PPE implant by blinded photograph review. Methods: This retrospective cohort study included consecutive pediatric patients who underwent auricular reconstruction with either autologous cartilage or PPE between November 2017 and February 2022. Blinded observers rated each postoperative ear through a web-based survey. Data on patient characteristics, operative time, length of admission, and complications were collected, bivariate analyses were performed using chi-square or Fisher's exact tests for categorical variables and Wilcoxon rank-sum test for continuous variables. Results: Forty-four ears were included, 28 of which (63.6%) were reconstructed with cartilage. Median patient age was 8 years (range 4-18 years) and 29 (65.9%) were male. The cartilage group had more surgeries (median 2.5 vs. 1.0, p < 0.001), and total operating time across all surgeries did not differ significantly. Conclusion: The two groups in our study had similar rates of complications and aesthetic scores, and aesthetic scores were worse for ears with wound complications requiring unplanned revisions.

Abstract
This study aimed to investigate the safety and efficacy of depilation with intense pulsed light (IPL) in congenital microtia patients during their reconstruction treatment. The hairy skin was treated with the M22TM system (Lumenis, German) using a filter of 695 to 1200 mm. A contact prob with a window of 15 cm × 35 mm or 8 cm × 15 mm was used at a radiant setting of 14 to 15 J/cm2 in the non-expander group and 13 to 14 J/cm2 in the expander group, both in a single pulse mode. The efficiency index of hair removal was classified based on the percentage of hair density reduction as excellent (>75%), good (50-75%), fair (25-50%), poor (<25%). The depilation effect was compared between the 2 groups, and any adverse effects were evaluated. A total of 159 patients were included, with 93 patients in the expander group and 66 in the non-expander group. The reduction of the hair density in the expander group after 3 treatments was higher than that in the non-expander group [82.98 (73.47-89.09)% vs 77.84 (71.50-85.34)%; P < .05, Wilcoxon rank-sum test], as well as the efficiency [excellent cases 68 (73.12%) vs 37 (56.06%); P < .05, Chi-square test]. Four cases of folliculitis, 3 cases of blisters, and no instance of expander exposure and cartilage absorption were observed in this study. Hair removal with IPL is a safe and effective photo-epilation method during all stages of ear reconstruction using tissue expander. Depilation in the skin expansion period resulted in better outcomes after 3 treatments, although after 5 treatments no difference between the 2 groups was observed.

Abstract
Despite various surgical techniques for ear elevation in autogenous cartilage microtia reconstruction, it is still challenging for plastic surgeons to obtain a satisfactory depth of the cephaloauricular sulcus and stable projection of the reconstructed ear. Here, the authors demonstrate individualized options for surgical approaches and relevant details for complication management. Between January 2014 and June 2020, a series of 895 patients who underwent the second stage of microtia reconstruction were reviewed. Complications occurred in 103 patients aged between 8 and 34 years. Recommended surgical selections, as well as appropriate strategies for complication prophylaxis and treatment, were shown to minimize the negative influence on the contour of the cephaloauricular sulcus according to individual conditions. We found that 78% of the patients were satisfied with the auricle contour with harmonious integrity. Individualized strategies for ear elevation and complication treatment contribute to symmetry and satisfactory projection of the reconstructed auricle.

Abstract
OBJECTIVES Complications, including framework exposure, infections, and reconstructed auricle deformation, may occur after auricular reconstruction. However, reports on surgical methods for cases with unsatisfactory outcomes after auricular reconstruction using an autologous costal cartilage are insufficient. Herein, we summarized retreatment casesfor poor ear morphology in patients who had undergone auricular reconstruction in our department for 5 years and discussed other techniques. METHODS Between September 2014 and September 2019, 24 ears of 24 patients with poor morphology, unsatisfactory macroscopic characteristics and anatomical structures, and unsatisfactory outcomes of local repair after auricular reconstructive surgery were treated. Patients were divided into the following three groups: type 1 (9 ears), with intact and sufficient hairless skin in the mastoid region behind the reconstructed ear; type 2 (7 ears), with intact, but insufficient, hairless skin in the mastoid region behind the reconstructed ear; and type 3 (8 ears), with hairless skin in the mastoid region behind the reconstructed ear with impaired skin integrity. RESULTS Twenty-two (91.6%) patients successfully completed the surgical treatment and recovered well; one experienced delayed wound healing and another developed hypertrophic scarring at the incision site at 3 months postoperatively. All patients were followed for 0.5-4 (mean, 2.8) years. The macrostructure of the reconstructed ear post-revision was stable and significantly improved in terms of morphology and structure. CONCLUSIONS In patients with unsatisfactory outcomes after auricular reconstruction, the appropriate technique for the revision surgery should consider the local soft tissue conditions of the reconstructed ear to obtain satisfactory results.

Abstract
This study aimed to compare the therapeutic effects of biplane skin dilator implantation with those of conventional skin dilator implantation in auricular reconstruction. A total of 137 patients with microtia who met the inclusion criteria from January 2020 to April 2021 were retrospectively selected. Sixty-three patients comprised the control group and were implanted with a skin expander using the conventional method. Seventy-four patients comprised the experimental group and were implanted with a skin expander using the biplane method. Non-parametric tests were used to compare the down-moving distance of the skin dilator between the experimental group and the control group. There was a statistically significant difference in the down-moving distance of the skin dilator between the experimental group and the control group (P < 0.05). The chi-square test showed no significant difference in postoperative complications between the experimental group and the control group (P > 0.05). Moreover, there was no significant difference in the satisfaction rate of patients and their families between the experimental group and the control group (P > 0.05). In this study, the treatment effect of biplane skin dilator implantation was better than that of conventional skin dilator implantation.

Abstract
OBJECTIVE The authors conducted this meta-analysis to compare the efficacy of auricle reconstruction using tissue expanders with skin grafting and auricle reconstruction using tissue expanders without skin grafting by comparing the 6 major evaluation indicators. METHODS The databases such as PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Wanfang, and VIP information databases were searched. RESULTS By comparison, the authors found that, the satisfaction rate, the incidence of postoperative hematoma, the incidence of postoperative incision infection, and the incidence of cartilage framework exposure of patients with auricle reconstruction using tissue expanders with skin grafting were all lower than those with auricle reconstruction using tissue expanders without skin grafting. However, the incidence of postoperative skin necrosis, the incidence of leakage or exposure of expanders in patients with auricle reconstruction using tissue expanders with skin grafting were all higher than those with auricle reconstruction using tissue expanders without skin grafting. CONCLUSIONS Auricle reconstruction using tissue expanders with skin grafting has advantages in reducing the incidence of postoperative hematoma, the incidence of postoperative incision infection, and the incidence of cartilage framework exposure. Auricle reconstruction using tissue expanders without skin grafting has advantages in improving the satisfaction rate, reducing the incidence of postoperative skin necrosis, and the incidence of leakage or exposure of expanders. From the comparison of specific data, there is no significant difference in the treatment effect between the 2 surgical methods.

Abstract
BACKGROUND In ear reconstruction, the difficulty lies in reestablishing the ear's bionic form with adequate skin coverage and an appropriate framework. Skin expansion and a porous polyethylene (i.e., Medpor) framework are often used for ear reconstruction. However, a long-term review of the combined application of the expanded skin and Medpor framework has not been reported. This article reviews ear reconstruction combining these two factors over the past 20 years in the authors' center to summarize the surgical technique and analyze the postoperative results and complications. METHODS A retrospective review was performed that included all patients who underwent ear reconstruction with expanded skin and Medpor framework in the authors' center between 1998 and 2018. RESULTS A total of 68 patients with microtia who were admitted to the authors' center for surgical ear reconstruction were included, and 70 ears were reconstructed. Fifty-seven of the patients (83.82 percent) felt satisfied with their reconstructed ear, five patients (7.35 percent) were not satisfied with the reconstructed ear, and six patients (8.82 percent) had the frameworks removed. Fifteen patients (22.06 percent) developed complications, including framework exposure (13.24 percent), infection (4.41 percent), scar hypertrophy (4.41 percent), and hematoma (2.94 percent). CONCLUSIONS Framework exposure limits the combined application of expanded skin flap and Medpor framework when reconstructing the ear without additional fascial interposition. Using a temporoparietal fascia or postauricular fascia flap during the operation is effective to decrease the exposure rate; however, this complication cannot be completely avoided. Using postauricular fascia and skin graft may lead to scar hypertrophy; thus, these techniques should be used with caution. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
BACKGROUND Auricular reconstruction for microtia is most frequently performed using autologous costal cartilage (ACC) or porous polyethylene (PPE) implants. Short-term results are generally promising, but long-term results remain unclear. Long-term outcomes were explored in this systematic review, and minimal reporting criteria were suggested for future original data studies. METHODS A systematic literature search was conducted in MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from inception through October 14, 2020. Articles on auricular reconstruction in patients with microtia using ACC or PPE were included if postsurgical follow-up was at least 1 year. Outcome reporting was split into separate publications, and results on complications were reported previously. This publication focused on long-term aesthetic, patient-reported, and sensitivity outcomes. RESULTS Forty-one publications reported on these outcomes. Both materials led to aesthetically pleasing results and high rates of patient satisfaction. ACC frameworks grew similarly to contralateral ears, and the anterior surface of auricles regained sensitivity. Furthermore, postoperative health-related quality of life (HRQoL) outcomes were generally good. Data synthesis was limited due to considerable variability between studies and poor study quality. No conclusions could be drawn on the superiority of either method due to the lack of comparative analyses. CONCLUSION Future studies should minimally report (1) surgical efficacy measured using the tool provided in the UK Care Standards for the Management of Patients with Microtia and Atresia; (2) complications including framework extrusion or exposure, graft loss, framework resorption, wire exposure and scalp/auricular scar complications and (3) HRQoL before and after treatment using the EAR-Q patient-reported outcome measure (PROM).

Abstract
BACKGROUND Microtia is a rare disorder characterized by malformation or even complete absence of the auricle. Reconstruction is often performed using autologous costal cartilage (ACC) or porous polyethylene implants (PPE). However, the long-term outcomes of both methods are unclear. OBJECTIVE This systematic review aimed to analyze long-term complications and suggest minimal reporting criteria for future original data studies. METHODS A systematic literature search was conducted in MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials from inception through October 14, 2020. Articles on auricular reconstruction in patients with microtia using ACC or PPE were included provided that the follow-up period was at least one year. This publication focused on long-term complications reported in patients with a postoperative follow-up period of at least one year. RESULTS Twenty-nine publications reported on complications during long-term follow-up. Overall long-term complication rates were not reported. The incidence of individual complications during long-term follow-up was less than 10% after ACC reconstruction and less than 15% in PPE reconstruction. Framework resorption and wire exposure were reported even after an extended follow-up of more than five years after ACC reconstruction, while reports on the extended long-term results of PPE reconstruction are limited. Data synthesis was limited due to heterogeneity and poor study quality. CONCLUSIONS Future studies should report on long-term complications including framework exposure or extrusion, graft loss, framework resorption, wire exposure and scalp and auricular scar complications. We recommend a surgical follow-up of at least five years.

Abstract
Background As one of the most widely used methods to treat microtia, the auricular reconstruction proposed by Zhuang may have several drawbacks. This study aimed to introduce a modified Zhuang's ear reconstruction technique by using a reformative inflation method and remnant ear to shorten therapy time and avoid skin grafting in a two-stage operation for patients with microtia. Methods A total of 124 patients with microtia were enrolled consecutively from 2014 to 2018. Among them, 66 patients underwent a modified Zhuang's method, and the remaining patients underwent Zhuang's method. The clinical and perioperative characteristics of patients, as well as complications and esthetic outcomes were analyzed. Results Compared with Zhuang's group, our modified Zhuang's group had better average esthetic scores according to two plastic surgeons [11.5 (IQR, 10.5-12.5) vs. 9.5 (IQR, 7.5-11.0), P<0.001], fewer hypertrophic scar cases [0% (n=0/66) vs. 10% (n=6/58), P = 0.024], shorter whole therapy duration [2.5 (IQR, 2.4-2.6) vs. 5.0 (IQR, 5.0-5.1) days, P<0.001] and shorter hospital duration after operation [5 (IQR, 5-6) vs. 6 (IQR, 5-6) days, P=0.013]. Conclusions Our modified Zhuang's technique is a new method to treat microtia which results in a clear contour of the reconstructed ear and matching skin color, minimal scarring, and a short treatment time.

Abstract
OBJECTIVES Ear reconstruction is a challenging surgery for the complicated conditions in patients with microtia. The tissue expansion techniques were necessary and relatively safe for patients with insufficient soft tissue. However, complications such as necrosis of expanded flap and exposure of tissue expander limited the popularization of this method. This study described the use of modified Brent method to handle the exposure of the postauricular tissue expander. METHODS From January 2013 to December 2019, 27 ear reconstruction patients with trauma or necrosis on an expanded skin flap and subsequent exposure of tissue expander were treated with modified Brent method, which consisted of 3 stages: removal of the expander, tension-free closure of wound, and framework fabrication; elevation of reconstructed ear; lobule rotation; and minor modification. RESULTS Fifty-six percent of exposures occurred in the lower pole of the tissue expander. Exposure usually occurred 54.5 days after implantation. The majority of reconstructed ears had a satisfactory appearance and showed relatively stable outcomes. Only one case of cartilage exposure required revision surgery and was repaired by the temporoparietal fascia. CONCLUSION With reasonable distribution of expanded flap, prolonged interval, and sutures under tension-free conditions, complications like the occurrence of trauma or necrosis-induced exposure of tissue expander can be repaired efficiently by a staging modified Brent method.

Systematic Review of Tissue Expansion: Utilization in Non-breast Applications. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3378.

Abstract
Background Tissue expansion is a versatile reconstructive technique providing well-vascularized local tissue. The current literature focuses largely on tissue expansion for breast reconstruction and in the context of burn and pediatric skin/soft tissue replacement; however, less traditional applications are also prevalent. The aim of this study was to systematically review the utilization of tissue expansion in such less well-characterized circumstances. Methods The authors conducted a systematic review of all publications describing non-breast applications of tissue expansion. Variables regarding expander specifications, expansion process, and complications were collected and further analyzed. Results A total of 565 publications were identified. Of these, 166 publications described tissue expansion for "less traditional" indications, which fell into 5 categories: ear reconstruction, cranioplasty, abdominal wall reconstruction, orthopedic procedures, and genital (penile/scrotal and vaginal/vulva) reconstruction. While lower extremity expansion is known to have high complication rates, tissue expander failure, infection, and exposure rates were in fact highest for penile/scrotal (failure: 18.5%; infection: 15.5%; exposure: 12.5%) and vaginal/vulva (failure: 20.6%; infection: 10.3%; exposure: 6.9%) reconstruction. Conclusions Tissue expansion enables index operations by providing additional skin before definitive reconstruction. Tissue expanders are a valuable option along the reconstructive ladder because they obviate the need for free tissue transfer. Although tissue expansion comes with inherent risk, aggregate outcome failures of the final reconstruction are similar to published rates of complications without pre-expansion. Thus, although tissue expansion requires a staged approach, it remains a valuable option in facilitating a variety of reconstructive procedures.

Abstract
Background Total auricular reconstruction is a challenge for plastic surgeons. Expanded flap method and Nagata’s method with autologous costal cartilage are two leading techniques for ear reconstruction. And a two-stage strategy of expanded flap method received attention. In the present study, we report the incision and flap design of this strategy. Methods In the first stage, an 80 mL kidney-shaped expander was inserted in the mastoid region with the larger pole superiorly. The expander pocket was dissected subcutaneously in the scalp area and subfascially in the lower third region. In the second stage, the expander was removed from a Y-shaped lobule incision on the remanent ear. Then the remnant ear was separated into three flaps: the posterior skin flap, anterior skin flap, and lobule flap. When the framework was fabricated, the base frame and the underlying pad, which enhanced the projection, were fixed together as a whole to provide a more prominent appearance. The framework was totally wrapped into the expanded single flap without free skin grafting. Lobule transposition and tragus construction were performed simultaneously instead of a third-stage surgery. The recipient bed of rotated lobule was resected only to the epidermal layer and the subcutaneous layer was preserved to avoid central necrosis. Results A total of 21 patients received this strategy to reconstruct ear. With 3 months to 1.5 years of follow-up, 19 patients (90.5%) were satisfied with the reconstructed ears. 3 patients (14.3%) required further modification of reconstructed ear. No serious complications occurred during the procedures. Conclusions With a Y-shaped incision, three-flap design of remanent ear and lobule rotation to an epidermal-removal area, tissue expander removal and modification of remanent ear can be performed effectively to avoid necrosis and an extra operation.

Abstract
BACKGROUND Autologous repair using costal cartilage grafts remains the most widely accepted method of microtia reconstruction. A major complication of current techniques is loss of ear shape caused by scarring, contracture and cartilage absorption. We present a new surgical technique utilizing the posterior auricular artery free flap in microsurgical reconstruction of the retroauricular sulcus in microtia. METHOD Reconstruction is performed in two stages. In the first stage, a fabricated costal cartilage framework is inserted into a skin pocket as described by Nagata. In the second stage, the ear framework is elevated from the scalp and held by an additional cartilage wedge. Following indocyanine green angiography perforator mapping, a posterior auricular artery perforator flap is harvested from the contralateral (normal) ear and used to reconstruct the posterior auricular sulcus covering the cartilage framework and elevating wedge. RESULTS The technique was applied to three patients aged 11-15 years with a follow-up time of 8 months to 3 years. The average flap artery diameter was 0.73 mm and the vein was 0.7 mm. Venous congestion occurred in one case and was resolved with a vein graft leading to complete flap recovery. Good ear shape, elevation, projection, skin color and texture were achieved in all the cases. CONCLUSION Posterior auricular artery flap reconstruction of the retroauricular sulcus in microtia repair is a useful alternative to the current skin graft and tissue expander-based techniques. It provides the ideal skin color and texture match and may improve the overall results of microtia reconstruction by enhancing vascularity.

Abstract
The external ear is highly vulnerable to burn injury due to its location and thin integument. Reconstruction of the external ear after burns is a major challenge to undertake, and surgeons face many problems, including excessive scar tissue, poor blood supply, a paucity of available skin, and a high infection rate, when designing an operative plan for patients with postburn auricular deformity. In this article, the authors describe their experience of using an expanded postauricular scar flap combined with a postauricular fascial flap as the coverage for the framework for subtotal and total ear reconstruction in 27 burned patients. Four patients developed expander exposure and two developed framework exposure, which were resolved with good results after further repair. After an average follow-up time of 6 months, all of the patients experienced very good cosmetic outcomes, high satisfaction, and low morbidity.

Abstract
Reconstruction of auricular deformities and facial scars after burns is a challenging undertaking for surgeons. Excessive scar tissue, a poor blood supply and the paucity of available skin are all substantial difficulties that should be considered before the operation. Expanded neck flaps provide comparatively larger and thinner flaps for the simultaneous treatment of auricular deformities and facial scars in burn patients. In this article, the authors introduced the use of an expanded neck flap as coverage tissue for ear reconstruction and face resurfacing in 2 burn patients. The operation consisted of 3 stages. In the first stage, the expander was implanted subcutaneously under the skin of the neck to create adequate skin and soft tissue. In the second stage, the expander was removed, and the expanded flap was transferred to cover defects on the auricle and face. The third operation to repair the reconstructed ear and thick flap could be performed according the willingness of the patients and surgeons. Esthetically satisfactory results were achieved in both of the patients. The flaps survived completely, and the skin color, texture, and flexibility were well matched to those of the peripheral tissue. Six months postoperatively, the flaps did not shrink, and subsequent contractures did not recur. Both of the patients experienced high satisfaction, and no adverse effects were detected.

Abstract
OBJECTIVES Ear deformity caused by burns is one of the most difficult types of deformity to treat with plastic surgery, and the reconstruction of burned ears undoubtedly remains a substantial challenge. This study aims to report the therapeutic regime of using a superficial temporal fascial flap to cover the framework in burned ear reconstruction. METHODS Autologous costal cartilage was used to form the ear framework in all of the reconstruction cases. A superficial temporal fascial flap was used as soft tissue to cover the ear scaffold. RESULTS Five patients with 6 ears were included in our study. The external ear healed well and the location, size, and shape of both ears were generally symmetrical. No complication was observed in any of the patients. CONCLUSIONS The superficial temporal fascial flap is a good choice for covering the autogenous cartilage framework when treating ear deformities after burns.

Abstract
BACKGROUND The chest wall deformity is a well-known complication following costal cartilage harvest with the biomechanical factor considered to be a cause of this donor-site morbidity. Kawanabe-Nagata method is a widely-accepted approach to prevent the deformity. However, knowledge about the biomechanical properties of regenerated costal cartilage is limited, and the value of reimplantation of autologous costal cartilage blocks is not clear. METHODS The fifth costal cartilage on both sides of six male, 8 weeks of age, New Zealand white rabbits were harvested with the perichondrium preserved intact in situ. The perichondrium was sutured to form a perichondrial pocket and part of the excised costal cartilage was cut into 0.5 mm cartilage blocks and returned to the perichondrial pocket of left side. The animals were sacrificed 16 weeks postoperatively and the regenerated and a piece native costal cartilage was harvested for morphological and three point bending test. RESULTS There was no remarkable chest wall deformity in all animals, and there were no apparent differences in the appearance of the regenerated cartilage with and without reimplantation autologous cartilage blocks. The elastic modulus of native cartilage was significantly higher than the regenerated cartilage. The stiffness of regenerated cartilage without reimplantation was higher than that of with reimplantation, but this difference was not significant. CONCLUSIONS The stiffness of regenerated cartilage was significantly lower than the native cartilage. Reimplantation of autologous cartilage blocks was not superior to that without reimplantation in regard to restoring the volume defect and strengthening the regenerated cartilage.

Total Auricular Reconstruction Using a Single Extended Postauricular Flap Without Skin Grafting in Two Stages: Experiences of 106 Cases. Aesthetic Plast Surg 2020; 44:365-372. [PMID: 31359087 DOI: 10.1007/s00266-019-01459-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2019] [Accepted: 07/02/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Postauricular fascial flap with skin grafting is popular as a solution in total auricular reconstruction, which might result in visible scars and mismatched color, especially in Asian people. Other methods using an expanded postauricular flap to avoid skin grafting often require three or more operations, which increases suffering for patients. This work aims to introduce a modified technique for auricular reconstruction using a single expanded postauricular flap without skin grafting in a two-stage operation. METHODS An 80-ml kidney-shaped expander was implanted in the mastoid area as the first-stage operation after preoperative evaluation. After a gradual expansion period and a 2-month rest time, the flap achieved the appropriate size and thickness. In the second stage, a three-layer cartilage framework was fabricated and inserted into the pocket through an incision at the remnant ear, and the earlobe and tragus were rebuilt simultaneously. RESULTS From September 2013 to October 2017, 106 microtia patients were selected for auricular reconstruction applying this method in our hospital. Patients were followed up to 6 months to 4 years. Most of them (93.4%) were satisfied with the reconstructed ears, especially with respect to suitable color and invisible scars. Complications of expander exposure or framework exposure happened in three cases, and all of them finally got a satisfactory result. CONCLUSION A single large expanded postauricular flap without a skin graft is an effective and efficient technique for auricular reconstruction with satisfying results. It can reconstruct an exquisite ear without a skin graft and can be finished in only two stages of operations.

Abstract
BACKGROUND The authors aim to present a comprehensive review detailing the present state of evidence with regard to complications following tissue expansion in the head and neck. METHODS A systematic literature search was conducted to identify all studies reporting complications of tissue expansion in the head and neck between 2000 and 2019. Subgroup comparisons based on expander locations and planes were conducted. RESULTS A total of 7058 patients were included. Tissue expansion was associated with an overall complication rate of 8.73% (616/7058). The most common complications were extrusion (207/7009; 3.0%) and hematoma (200/7009; 2.9%). Overall complications were highest in the scalp (65/238; 27.3%) and lowest in the mastoid (347/5688; 6.1%). Complications were more common with expansion in the non-subcutaneous plane (63/590; 10.7%). CONCLUSION In the absence of large clinical trials, systematic reviews such as these can help inform clinical guidelines and provide practitioners with an evidence-based reference to improve informed consent.

Abstract
Clinicians use different diagnostic terms for patients with underdevelopment of facial features arising from the embryonic first and second pharyngeal arches, including first and second branchial arch syndrome, otomandibular dysostosis, oculoauriculovertebral syndrome, and hemifacial microsomia. Craniofacial microsomia has become the preferred term. Although no diagnostic criteria for craniofacial microsomia exist, most patients have a degree of underdevelopment of the mandible, maxilla, ear, orbit, facial soft tissue, and/or facial nerve. These anomalies can affect feeding, compromise the airway, alter facial movement, disrupt hearing, and alter facial appearance.

Abstract
BACKGROUND Auricular reconstruction is one of the most challenging procedures in the field of plastic surgery. The aims of this study were to apply the modified 2-stage method to perform auricular reconstruction and to summarize the clinical experience in the past 10 years. METHODS Auricular reconstruction was performed in 243 patients (total 254 ears) of congenital microtia using autologous costal cartilage. The whole procedure is divided into 2 stages. Stage I: the individualized framework fabricated with autologous costal cartilage is inserted into subcutaneous pocket in the mastoid region, and then the earlobe was transposed backward to connect with the lower part of the framework. The second-stage surgery mainly includes the following main contents: ear elevation, fixing the bracket behind the reconstructed ear framework, harvesting the retroauricular fascial flap to cover the bracket, and closing the defect with free skin grafts. RESULTS A total of 243 patients (254 ears) of congenital microtia underwent ear reconstruction. The follow-up time ranged from 6 months to 4 years; 220 patients were satisfied with the results. Surgery-related complications such as infection, partial skin graft necrosis, flap necrosis, bad projection of the constructed auricle, and extrusion of cartilage occurred in 24 cases, and hypertrophic scars occurred in 16 patients. CONCLUSIONS This modified 2-stage method for auricle reconstruction can receive acceptable results and fewer complications; furthermore, it is relatively simple and easy to master. The 10-year experience validates that this modified method is an ideal method in auricular reconstruction.

Abstract
BACKGROUND Auricular reconstruction is one of the most challenging procedures in plastic surgery. An adequate skin envelope is essential for cartilage framework coverage, yet few good options exist without additional surgery. We propose a novel method for minimally invasive tissue expansion, using hyaluronic acid (HA) filler to allow for single-stage ear reconstruction. OBJECTIVES To introduce the novel concept of HA filler for tissue expansion in ear reconstruction, and as an alternative to traditional expansion techniques. METHODS Macrolane is a large particle HA gel developed for large volume restoration. Expansion of the non-hair-bearing mastoid skin was performed in our clinic weekly or every other week. Final expansion was completed one week prior to reconstructive surgery. Tissue from one patient's expanded pocket was sent for histological analysis. RESULTS Ten patients underwent single-stage auricular reconstruction with preoperative expansion. Injection sessions ranged from 7 to 13 (mean, 9.7). Mean injected volume per session was 2.03 mL per patient, for an average total of 19.8 mL (range, 14.5-30 mL). There were no major complications. One minor complication required removal of exposed wire from the antihelix in the office. Hematoxylin and eosin stain revealed similar histology to that seen with traditional expanders. CONCLUSIONS This novel expansion technique using serial HA injections allowed for optimized skin coverage in single-stage ear reconstruction. The concept of tissue expansion using HA filler is a new frontier for research that may be applicable to other arenas of reconstruction. LEVEL OF EVIDENCE 4.

Abstract
OBJECTIVE The objectives of this study were to evaluate sternal development and variations in patients with microtia and to identify the incidence of congenital sternal anomalies and then to investigate the interaction between microtia and sternal anomalies. METHODS A total of 212 consecutive patients received a preoperative 3-dimensional chest computed tomography. A retrospective study was performed with the clinical and imaging data from November 2014 to July 2015. Descriptive statistics, analysis of variance, Spearman analysis, χ test, and Fisher χ test were performed for statistics analysis. RESULTS We evaluated the ossification centers and developmental variations in the manubrium and body, as well as the xiphoid process, manubriosternal and sternoxiphoidal fusion, and sternal anomalies. Significant variations were observed from person to person. Sternal foramen was detected in 6 male patients (2.8%). All foramina were located in the inferior part of the body. Sternal cleft was observed in 4 cases (1.9%), of which 2 were accompanied by a foramen in the distal part of the sternum. CONCLUSIONS The development of the different components of the sternum is a process with wide variation among patients with microtia. A different distribution of mesosternal types I to II among our population age range was found, and the incidence of sternal foramina was lower in patients with microtia.

Abstract
BACKGROUND Ear reconstruction is one of the most complicated and challenging techniques in plastic surgery because of the histologic and anatomic properties of the ear. Success depends on fitting the auriform cartilage scaffold into the overlying skin, but current approaches can just give results that are not lifelike and can lead to complications. MATERIALS AND METHODS A novel double-capsule, double-valve plastic ear expander was designed and implanted subcutaneously on either side of the dorsum of six New Zealand white rabbits (two expanders per rabbit). The outer capsule was expanded by injecting approximately 120 mL of physiological saline, then withdrawing the liquid on two occasions. Next, the ear-shaped inner capsule was filled with high-hardness plaster, and the external capsule was emptied such that the expanded skin flap and external capsule responded to the negative pressure and closed over the ear-shaped inner capsule. As a result, the skin flap adopted an ear shape. The ear expander was left in place for 4 wk, removed with the help of a mini-incision, and stripped of its fibrous capsule. To simulate human ear reconstruction, the expander was replaced with an auriform silicone prosthesis, and the effects of auricular reconstruction were observed dynamically. RESULTS All 12 skin flaps maintained abundant blood supply, created a clear outline of the ear framework, and produced a lifelike result. No complications were observed during the 4-wk observation period. CONCLUSIONS The expanded skin flaps described here can mold to the desired contours and appear lifelike, as well as maintain abundant blood supply. This may provide a simpler approach to total ear reconstruction that reduces risk of complications.

Abstract
Background: Autologous cartilage has been widely accepted as the frame material of ear reconstruction for patients with microtia. Although rare, there are multiple complications related with the surgical reconstruction techniques. The authors performed a systematic review of the English literature of microtia reconstruction to determine significant surgical factors that are predictors of postoperative complications. Methods: A PubMed search using the terms “ear reconstruction” and “microtia” was conducted. Articles were screened using predetermined inclusion and exclusion criteria. Data collected included patient characteristics, surgical techniques, the incidence of all kinds of complications, and the specific postoperative morbidity. Patient cohorts were pooled, and the incidence of complications was calculated. Significant predictors such as the use of tissue expander, simultaneously mid-ear reconstruction, with/without skin graft, and different fascia coverage were analyzed by chi-square test. Result: Of 320 articles found, 60 met the inclusion criteria. Totally 9415 patients with microtia were analyzed in this review with 1525 cases with complications. The overall complication incidence is 16.2% in average with a range of 0–72.9%. There was no significant difference when comparing the overall complication rate between with/without preexpansion 2-stage and multiple-stage techniques or with/without mid-ear reconstruction simultaneously. Conclusion: Although there is little agreement in literature regarding risk factors for complications, the authors were able to demonstrate several significant predictors by systematically analyzing 60 articles. Improved knowledge of the incidence of different complications related with various surgical methods can help surgeons provide improved preoperative counseling and take measures to minimize the risk.

Abstract
Craniofacial microsomia (CFM) is one of the most common congenital conditions treated in craniofacial centers worldwide. This condition is variably associated with anomalies of the jaws, ears, facial soft tissue, orbits, and facial nerve function and can be associated with extracranial anomalies. The cause of this condition is unknown, though CFM has been associated withprenatalexposures and genetic abnormalities. Diagnosis, treatment, and outcome assessment in CFM is challenging due to the wide phenotypic spectrum observed in this condition. Surgical treatment requires a coordinated team approach involving multiple specialties, which can include plastic surgery, craniofacial surgery, orthognathic surgery, and microsurgery. A wide variety of surgical options exist, and individual treatment plans should be based on the patient's needs. Although CFM can be challenging to treat, successful outcomes are rewarding. We provide a review of the common craniofacial surgical treatments for individuals with CFM.

Abstract
The loss of cartilage tissue due to trauma, tumour surgery or congenital defects, such as microtia and anotia, is one of the major concerns in head and neck surgery. Recently tissue-engineering approaches, including gene delivery, have been proposed for the regeneration of cartilage tissue. In this study, primary chondrocytes were genetically modified with plasmid-encoding bone morphogenetic protein-7 (BMP-7) via the commercially available non-viral Turbofect vector, with the aim of bringing ex vivo transfected chondrocytes to resynthesize BMP-7 in vitro as they would in vivo. Genetically modified cells were implanted into gelatin-oxidized dextran scaffolds and cartilage tissue formation was investigated in 15 × 15 mm auricular cartilage defects in vivo in 48 New Zealand (NZ) white rabbits for 4 months. The results were evaluated via histology and early gene expression. Early gene expression results indicated a strong effect of exogenous BMP-7 on matrix synthesis and chondrocyte growth. In addition, histological analysis results exhibited significantly better cartilage healing with BMP-7-modified (transfected) cells than in the non-modified (non-transfected) group and as well as the control.

Abstract
Successful ear reconstruction depends on two factors: an ear framework and the skin covering the framework. However, the relative deficiency of skin for coverage of the cartilage framework remains an issue. This new method for total auricular reconstruction is a three-stage operation and involves the use of two tissue expanders. First, two skin expanders are implanted, one underneath the scalp and the other sited behind the microtic ear. At the second stage, after lobule transposition, the two expanded skin flaps (upper and lower) and mastoid fascial flap are raised. At the same time, the autogenous rib cartilage is harvested and the framework constructed. The cartilage framework is then anchored between the upper expanded skin flap and the fascial flap with its inferior pole inserted into the rotated earlobe. The upper expanded skin flap covers the whole anterior surface of the framework and drapes over the margins of the fascial flap, which wrap the framework from beneath. The raw surface of fascial flap is covered with the lower expanded skin flap. The formation of a pseudomeatus and tragus is performed at the third stage. Deficiency of skin is the major problem encountered with the other conventional methods. Our innovations using two tissue expanders in combination with an autogenous rib cartilage framework eliminate this problem completely.

Salvage of expanded skin flap perforation and infection after total ear reconstruction with autogenous costal cartilage. J Craniofac Surg 2011; 22:805-8.

Abstract
INTRODUCTION This study was intended to present methods for salvage perforation and infection of an expended skin flap in total ear reconstruction with autogenous costal cartilage. METHODS Between March 2008 and March 2009, 5 patients experienced complications (perforation and infection) after total ear reconstruction. The skin perforations were noted between 29 and 100 days after inflation. Continuous irrigation and suction drainage, local flap transposition, and pillow suturing were used to control the perforation and infection. Continuous irrigation and suction drainage, especially, should be maintained until ascertaining a negative conversion of the wound culture. RESULTS Perforation and infection of the reconstructed ear with an expanded skin flap healed successfully using continuous irrigation and suction drainage, local flap transposition, and pillow suturing. DISCUSSION We suggest that continuous irrigation and suction drainage with only minimal debridement of grafted autogenous costal cartilage could be satisfactory solutions for salvaging total ear reconstruction after complications.

Abstract
INTRODUCTION Post-traumatic ear reconstruction still remains a great challenge for plastic surgeons. In this article, we present the technique of post-traumatic ear reconstruction using a postauricular fascial flap combined with an expanded skin flap. METHODS From May 2007 to June 2009, 91 cases of post-traumatic ear defect were treated using a postauricular fascial flap combined with an expanded skin flap. Surgical procedure included postauricular-skin-flap expansion, removal of tissue expander, autogenous rib-cartilage-framework implantation, postauricular-fascial-flap lifting and split-thickness free-skin grafting. RESULTS With a follow-up duration of 6 months to 1 year, the described technique provided a nice final result, and the reconstructed ears showed good match in size, shape, colour and location to the contralateral normal ear. CONCLUSION Post-traumatic ear reconstruction using a postauricular fascial flap combined with an expanded skin flap is an ideal approach with good final results.
