Abstract
Background: Question mark ear is a rare congenital deformity, mainly characterized the interruption of the natural continuity between the lower border of the helix and the earlobe. In severe cases, the earlobe may be absent. In addition, there may be protrusion and outward expansion of the upper part of the auricle, with partial or complete disappearance of the antihelix. This article aims to introduce a technique that combines autologous costal cartilage carving with auricular cartilage folding to achieve a stable and aesthetic auricle. Method: This study included 26 patients with sporadic question mark ear deformity who were treated at our clinical center from January 2020 to December 2022. Based on the different appearances of the lower part of the auricle, they were divided into 2 categories:11 cases showed a natural continuity interruption between the helix and the earlobe, while 15 cases showed the absence of the earlobe. All patients underwent corrective surgery using costal cartilage transplantation combined with the upper part of the auricular cartilage folding, performed by senior surgeons. Results: Question mark ear was effectively improved and with no significant rebound. The average follow-up period was 8.4 months (ranging from 6 to 12 months). A satisfaction survey showed that 23 patients (88%) were satisfied, 3 patients (12%) were partially satisfied, and no patients were dissatisfied. Most patients experienced temporary swelling after surgery, which resolved within 3 months to half a year. Conclusion: Autologous costal cartilage transplantation combined with folding of the auricular cartilage is an ideal surgical method to correct question mark ear.

Abstract
Current 3D scanning and printing technologies offer not only state-of-the-art developments in the field of medical imaging and bio-engineering, but also cost and time effective solutions for surgical reconstruction procedures. Besides tissue engineering, where living cells are used, bio-compatible polymers or synthetic resin can be applied. The combination of 3D handheld scanning devices or volumetric imaging, (open-source) image processing packages, and 3D printers form a complete workflow chain that is capable of effective rapid prototyping of outer ear replicas. This paper reviews current possibilities and latest use cases for 3D-scanning, data processing and printing of outer ear replicas with a focus on low-cost solutions for rehabilitation engineering.

Abstract
OBJECTIVES Microtia is a severe congenital malformation of the external ear, and auricular reconstruction is still a challenge for plastic surgeons because of the complicated procedures and rare conditions. This study aimed to describe the location of subcutaneous effusion after auricular reconstruction and explore the clinical efficacy of the indwelling needle puncture drainage method in the treatment of local subcutaneous effusion. METHODS From January 2017 to December 2019, 1240 patients (1296 affected sides) who underwent auricular reconstruction using autogenous cartilage framework in the Plastic Surgery Hospital of Chinese Academy of Medical Science and Peking Union Medical College were selected. The local subcutaneous effusion occurred within 5 days after the drainage tube was removed, and the indwelling needle was used for puncture and drainage in the postoperative treatment. RESULTS A total of 55 patients had subcutaneous effusion after the operation, including 24 cases with Nagata's method and 31 cases with the expanded single-flap method. One patient showed no obvious reduction after puncture and drainage by indwelling needle and improved after the secondary operation. Two patients had slight cartilage absorption. The remaining patients had good results. CONCLUSIONS The method of the indwelling needle for puncture and drainage is easy to operate. The problem of local subcutaneous effusion after auricular reconstruction can be solved and good efficacy can be obtained.

Abstract
OBJECTIVES Auricular reconstruction is a great challenge for surgeons to achieve good aesthetic outcomes when adjacent tissues were burned. Compared with pedicle flap therapies, there are some advantages of pre-expanded free flaps for ear rebuilding, such as thinner layer tissues for aesthetic requirements of delicate auricular structures and less donor site deformity. In this study, the authors introduced 6 sequential surgical procedures for total auricular reconstruction with severe ipsilateral facial scar. METHODS Pre-expanded deltopectoral flap was used to release periauricular contracture and repair facial scar. The injured ear was restored by expanded forearm flap including autologous cartilage framework. The surgical procedures were lasted more than 2 years. An 8 and half year's follow-up was performed from November 2012 to April 2021. The clinical data and surgical techniques were recorded and analyzed. RESULTS The patient was satisfied with the aesthetic outcomes of the new ear. The skin texture and color of the grafts were approximately matched to the recipient sites. Facial expression was not affected severely. Sensations of the transferred flap and new ear had partially recovered. The donor sites were recovered without severe complication. CONCLUSIONS The pre-expanded free forearm flap is a feasible method for total ear reconstruction when local flap therapies could not be applied. Repair of ipsilateral facial scar is beneficial for auricular procedures.

Abstract
BACKGROUND Auricular reconstruction is the sole therapy for external ear deformities. The flap pocket method and the expansion method are currently the two principal auricular reconstruction methods in microtia. The efficacy and safety of these two surgical techniques has long been a subject of controversy, bedeviled by a lack of objective comparative evidence. METHODS The authors searched the PubMed, Embase, Web of Science and Cochrane Library databases for clinical studies on auricular reconstruction in microtia updated to Jan 1, 2021. A meta-analysis was conducted to estimate the major outcomes for patient convenience, incidence of complications and postoperative patient satisfaction. RESULTS A total of twenty-two articles involving 7963 patients were included in this study. Nine studies involving 2475 patients concerned the flap pocket method and thirteen studies involving 5488 patients concerned the expansion method. The pooled patient satisfaction rate was higher using the flap pocket method than the expansion method (90.5% versus 83.3%, p = 0.000). Total complication incidence was lower using the flap pocket method than with the expansion method (6.8% versus 9.5%, p = 0.000). There were zero expander-related complications using the flap pocket method, but a 4% complication incidence using the expansion method. The total treatment period for the flap pocket method was 5.57 ± 1.13 months, much shorter than the 10.75 ± 3.54 months (p < 0.05) of the expansion method. CONCLUSIONS In microtia, the flap pocket method scores higher on patient satisfaction, while having lower post-operative complications and a shorter treatment period compared with the expansion method.

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 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 This study was performed to explore the clinical application of the Nagata's technique for combing tissue expansion in auricular reconstruction. METHODS The auricular reconstruction was performed in two surgical stages. At the first stage, an 80 ml expander was inserted in the mastoid region after preoperative evaluation. After a gradual expansion period and nearly 2-month rest time, the flap achieved the appropriate area and thickness. At the second stage, the expander was removed and a three-layer cartilage framework was inserted into the pocket through a Y-shaped lobule incision, and the earlobe and tragus were rebuild simultaneously. RESULTS From 2012 to 2016, 104 microtia patients underwent auricular reconstruction with this method in our hospital. Patients were followed up for between 6 months and 2 years. Ninety-six patients and their families were satisfied with the results, especially the clear outline, appropriate color, good projection, and the symmetry of bilateral ears. Complications of ischemic necrosis of the distal earlobe and skin of the concha cavity occurred in two cases, hematoma after the first stage occurred in two cases, and four patients needed further restorations. CONCLUSIONS A novel two-stage strategy combing tissue expansion and Nagata's technique is an effective and efficient technique for auricular reconstruction with satisfying medium-term results.

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
When costal graft is contraindicated or refused by the patient, autologous total/subtotal auricular reconstruction represent a real challenge as limited surgical options has been described. Aim of present report is to offer a novel possible autologous reconstruction of the ear frame using a chimeric free medial femoral condyle (MFC) flap. We present a case of a 29 years old patient who had total loss of the upper 2/3 of the right ear after bombing in Somalia and secondary infected condritis (considered a relative contraindication for costal cartilage graft). The MFC flap was harvested with a chimeric skin paddle (7 × 5 cm), a thin sheet of femoral cortex (6.5 × 8 cm) was used as basal ear frame, while part of the contralateral concha was trimmed as support for the helix, with the periosteal component of the flap wrapping around the whole framework. The chimeric skin paddle assured the retroauricular skin coverage, while the anterior part of the construct was covered by a thinned dermal flap. Postoperative course was uneventful. A defatting procedure of the posterior skin paddle was performed at 2 months post-op. At 6 months post-op, the patient was satisfied with the result, could wear glasses and was socially integrated. This new application of the free chimeric MFC flap, despite being not the primary choice for ear reconstruction, guaranteed satisfactory results in terms of ear shape and infection prevention and may be considered when ordinary cartilage rib reconstruction is refused, contraindicated, or failed.
