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
OBJECTIVE Determine if the ideal location of the construct in microtia reconstruction for hemifacial microsomia (HFM) can be more accurately derived from measurements on the cranium. DESIGN High-resolution computerized tomography (CT) images were analyzed through craniometric linear relationships. SETTING Our tertiary care institution from 2000 to 2021. PATIENTS/PARTICIPANTS Patients diagnosed with HFM and microtia, who had high-resolution craniofacial CT scans, yielding 36 patients accounting for 44 CT scans. MAIN OUTCOME MEASURE(S) First, the integrity of the posterior cranial vault among HFM patients was determined. If proven to be unaffected, it could be used as a reference in the placement of the construct. Second, the position of the ear in relation to the cranium was assessed in healthy age-matched controls. Third, if proven to be useful, the concordance of these cranium-based relationships could be validated among our HFM cohort. RESULTS The posterior cranial vault is unaffected in HFM (P > .001). Further, craniometric relationships between the tragus and the Foramen Magnum, as well as between the tragus and the posterior cranium, have been shown to be highly similar and equally precise in predicting tragus position in healthy controls (P > .001). These relationships held true across all age groups (P > .001), and importantly among HFM patients, where the mean absolute difference in predicted tragus position never surpassed 1.5 mm. CONCLUSIONS Relationships between the tragus and the cranium may be used as an alternative to distorted facial anatomy or surgeon's experience to assist in pre-operative planning of construct placement in microtia reconstruction for HFM patients.

Abstract
The study analyzed vascular variations in microtia associated with hemifacial microsomia (HFM). A retrospective analysis was conducted on 47 patients with microtia and HFM, who underwent computed tomography angiography between November 2011 and May 2022. The vascular course and branching supplying the TPF were analyzed. Craniometric measurements were conducted to determine the horizontal distance from the porion and fronto-zygomatic suture (F-Z suture) to the vessels. On the affected side, the TPF was primarily supplied by either the superficial temporal artery (STA) or the postauricular artery-originated STA (Po-STA). The Po-STA (n = 29) was more prevalent than the STA (n = 18), and mostly exhibited a single frontal branch (n = 20). Craniometric analysis revealed that the Po-STA was closer to the porion, ear vestige, and F-Z suture than the STA on the non-affected side. Furthermore, a significant correlation was observed between the severity of mandibular hypoplasia and presence of Po-STA variation (Cramer's V = 0.498, p = 0.005). Microtia associated with HFM exhibits vascular variations in the TPF - in particular, a unique Po-STA variation. The Po-STA is prone to injury during ear reconstruction because of its proximity to the external auditory canal and ear vestige. Surgeons should be cautious of these anatomical variations for safer ear reconstruction procedures, and utilize preoperative imaging for meticulous planning.

Abstract
HYPOTHESIS Treatment of congenital microtia in adults remains challenging due to the unique physiological characteristics of the costal cartilages and retroauricular skin, which interfere with obtaining a satisfactory aesthetic result; thus, different perspectives and technical modifications during treatment are warranted. This article aims to present complementary new information and essential tips to refine the surgical technique in adult microtia reconstruction. METHODS A total of 346 adult microtia patients underwent surgical intervention at the Auricular Reconstruction Center of Plastic Surgery Hospital (Beijing, China) between 2006 and 2021. Each patient underwent a rigorous preoperative evaluation and stages one and two surgeries. RESULTS Patients were followed in our clinic for 6 months to 10 years (average: 15.3 months). The postoperative complication rate was 8.1%, which included cartilage exposure, broken helix, local hematoma, infection, poor skin graft survival, and scar hypertrophy. CONCLUSIONS Our results showed that the two-stage treatment strategy for adults is versatile, reliable, and effective for the treatment of congenital microtia.

Surgical Microtia Reconstruction in Hemifacial Microsomia Patients: Current State and Future Directions. Plast Reconstr Surg Glob Open 2022; 10:e4486. [PMID: 36032368 PMCID: PMC9400929 DOI: 10.1097/gox.0000000000004486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 06/27/2022] [Indexed: 11/27/2022]
Abstract
Background: Hemifacial microsomia (HFM) is one of the most common congenital craniofacial disorders. Among many other features, microtia is present in the large majority of these patients. However, mainly due to the unilateral hypoplastic anatomy, microtia reconstruction among this patient population remains a reconstructive challenge for plastic surgeons. Given that no clear standards exist, an evidence-based synthesis of the literature was devised. Methods: A systematic search of Pubmed, Medline, and Embase was carried out, in accordance with the PRISMA guidelines. Studies discussing surgical microtia reconstruction for HFM patients were retained. Qualitative data regarding study design, challenges addressed, specific recommendations, and their respective strengths/limitations were extracted from each. Retrieved recommendations were consolidated and assigned a level of evidence grade. Results: Although only 11 studies were included in this review, these provided 22 main recommendations regarding the eight HFM-specific challenges identified, which were of either grade C (n = 5) or D (n = 17). Included studies addressed construct location (n = 7), the low hairline (n = 6), soft tissue construct coverage (n = 6), earlobe reconstruction (n = 6), construct projection (n = 5), anomalies of the relevant neurovascular systems (n = 2), retroauricular construct coverage (n = 2), and sizing of the construct (n = 2). Conclusions: Given the many persisting reconstructive challenges regarding surgical microtia reconstruction for HFM patients, the authors present a comprehensive and evidence-based consolidation of recommendations specific to these challenges. The authors hope this systematic review can appropriately guide plastic surgeons and will ultimately improve care for this patient population.

A new treatment strategy for hemifacial microsomia: Auricular reconstruction with an expanded two-flap method and simultaneous mandibular distraction osteogenesis. J Plast Reconstr Aesthet Surg 2022; 75:1950-1957. [PMID: 35183465 DOI: 10.1016/j.bjps.2022.01.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2020] [Revised: 12/22/2021] [Accepted: 01/18/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND Owing to the complex clinical manifestations of hemifacial microsomia (HFM), multidisciplinary cooperation is required to achieve better therapeutic effects in terms of function and aesthetics. This study aimed to explore the efficacy of the expanded two-flap auricular reconstruction combined with mandibular distraction osteogenesis in the treatment of HFM. METHODS This surgical strategy was performed in three stages. In the first stage, the retroauricular skin was expanded with a tissue expander and a mandibular distraction device was installed. In the second stage, the traditional expanded two-flap method for auricular reconstruction was adapted, and the framework was fabricated with costal cartilage and wrapped with the expanded skin flap, retroauricular fascia flap, and full-thickness skin graft. In the final stage, the tragus and lobule were rebuilt, the concha cavity deepened, and the mandibular distraction device removed. RESULTS From January 2014 to November 2018, 166 HFM patients underwent auricular reconstruction with the expanded two-flap method and simultaneous mandibular extension in our hospital. The median follow-up period was 9.3 months. Of the 166 patients, 154 patients and their families were satisfied with the results, and only 16 patients experienced complications. CONCLUSIONS This three-stage technique of simultaneous auricular reconstruction and mandibular distraction osteogenesis is safe and effective in achieving facial symmetry, improving occlusal contact, shortening treatment course, and relieving patient's suffering, especially for HFM patients.

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 Total auricular reconstruction for hemifacial microsomia patients with extremely low hairline is a tough challenge in plastic surgery. In this work, a brand new technique using a singer expanded scalp flap without skin graft and combined with intense pulse light treatments (IPLT) for ear reconstruction is described in this special population. METHODS From January 2015 to April 2019, 41 hemifacial macrosomia (HFM) patients with 70-100% low hairline were enrolled in our study. Operative treatment was performed in 3 stages: 1. Expander insertion and inflation; 2. Expander removal, costal cartilage framework fabrication and auricular reconstruction; 3. Tragus reconstruction and reconstructed auricle refinement. Several IPLTs were performed every 45 days until local area become hairless during the whole course. The first IPLT could be executed either before all the operations or during the expansion period. The flap was treated with M22 system using a filter of 695-1200 nm. Follow up ranged from 10 months to 4 years. RESULTS During follow-up, 90.2% patients were surveyed as satisfied with the outcome, especially in the aspects of minimal scars, natural matched color and clear contour of the reconstructed ear. No serious complications happened. Patients starting the IPLT during the expansion period required less treatment times of depilation (p < 0.05). CONCLUSION Auricular reconstruction using a single expanded scalp flap combined with intense pulse light depilation is a safe, effective and less invasive technique for hemifacial microsomia with extremely low hairline, and providing highly satisfying results. Initialing the IPLD during the expansion period is recommended. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
BACKGROUND Numerous modifications have been successfully applied in microtia reconstruction over the past several decades, and lobular transposition has become a routine technique in a two-stage operation. However, it is still a demanding challenge to manipulate the remnant ear with various quantities or positions in lobule-type microtia. The authors demonstrate the relevant details of treating remnant tissue in different conditions. METHODS A total of 390 lobule-type microtia patients underwent autogenous costal cartilage auricular reconstruction between 2010 and 2015. Because the quantity or position of the remnant ear varies from patient to patient, corresponding tactics need to be taken into consideration for appropriate treatment. Four possible scenarios of remnant ear shape have been described, and relevant strategies for each were introduced. RESULTS Favorable reconstructed auricles with aesthetic natural earlobes have been produced; the location of the reconstructed ear is symmetric to the contralateral ear. It provides a harmonized framework and periphery tissue for the integrity of the contour of the constructed auricle. CONCLUSIONS Proper use of the remnant ear along with framework fabrication and skin flap dissection are critical factors for attaining a satisfactory contour of the auricle in microtia reconstruction. The authors' technique made it possible to construct a cosmetically refined ear with harmonious integrity. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, V.
