Selecting Flap Transfer Methods to Repair Helix Soft Tissue Defect Based on the Direction of Long Axis.

BACKGROUND: The posterior auricular flap has long been favored for repairing skin defects on the ear's surface. However, achieving optimal esthetic outcomes in ear reconstruction requires a flexible approach to flap transfer methods. While bipedicle advancement flaps are commonly used for body wound coverage, they are rarely used in auricular defect repair. OBJECTIVE: To propose a modified flap transfer approach based on the orientation of the auricular defect's long axis and assess the postoperative esthetic outcomes. METHODS: The authors reported 12 patients treated using 2 distinct flap transfer techniques. Mild to moderate helix soft tissue defects remained after excision of the masses. A direct island flap was created for patients with longitudinal defects to cover the defect. For patients with transverse defects, a combination of bipedicle and island flaps was used for repair. Scar quality and esthetic outcomes were assessed at least 6 months postsurgery using the Scar Cosmesis Assessment and Rating scale. RESULTS: All patients experienced no serious complications and achieved excellent cosmetic results. Patients undergoing combined flap transfer exhibited relatively more favorable esthetic outcomes. CONCLUSION: The authors propose a novel concept for repairing helix soft tissue defects by designing local flaps based on the direction of the defect's long axis. For repairing helix soft tissue defects with a long axis parallel to the auricular edge, the combined utilization of bipedicle advancement flap and island rotation flap transfer should be consideration more.

[Management of patients with complex ear deformities]. / Prise en charge des patients présentant des déformations complexes du pavillon de l'oreille.

Complex ear reconstruction requires specialized multidisciplinary care. Most patients present with microtia, often associated with hearing disorders. The management of these disorders is a priority, and reconstruction of the external ear remains optional. Nowadays, auricular reconstruction is based on the subcutaneous implantation of either autologous cartilage or an allogeneic implant. Autologous reconstruction requires highly specialized surgical expertise and involves harvesting rib cartilage but carries a lower risk of exposure compared to allogeneic implants. Both techniques yield good results with a high success rate and have a positive impact on the social functioning and daily life of patients.

La reconstruction complexe du pavillon auriculaire nécessite une prise en charge multidisciplinaire spécialisée. La majorité des patients nécessitant ce geste présentent une microtie, souvent associée à des troubles de l'audition. La prise en charge de ceux-ci est prioritaire et la reconstruction du pavillon reste facultative. Aujourd'hui, la reconstruction du pavillon se base sur l'implantation sous-cutanée d'une maquette de cartilage autologue ou d'un implant allogène. La reconstruction autologue demande une expertise chirurgicale hautement spécialisée et nécessite un prélèvement de cartilage costal mais présente un risque d'exposition inférieur par rapport à l'implant allogène. Les deux techniques permettent d'atteindre de bons résultats avec un taux de réussite élevé et un effet positif sur le fonctionnement social et le quotidien des patients.

Early Non-Surgical Treatment For Microtia Types 1 and 2.

Esthetic concerns and psychosocial distress often accompany auricular deformities and malformations in both children and their parents. Approximately 30% of newborns are affected by auricular anomalies, with 15% to 20% resulting in permanent defects. While surgical intervention is typically considered the gold standard for malformations, a non-surgical approach, such as splinting, molding, or other non-invasive techniques, can effectively address deformations if promptly administered by a specialist. Microtia, classified into 4 types, presents challenges ranging from fundamental structural anomalies in types 1 and 2 to severe defects in type 3 and complete absence of the external ear in type 4 (anotia). This study introduces a novel non-invasive treatment modality for microtia types 1 and 2. The cohort consisted of 5 newborns treated for microtia types 1 or 2 between 2022 and 2023. Utilizing the EarWell system, treatment was initiated before 3 weeks of age (mean age: 2 weeks), with an average treatment duration of 6.6 weeks, supplemented by molding treatment as needed. Minor adverse effects, such as simple dermatitis, were observed in 2 patients. All parents expressed high satisfaction with the esthetic outcomes, with 60% reporting extreme satisfaction. The prompt initiation of the treatment protocol for microtia types 1 and 2 led to outstanding and timely outcomes in infants, enhancing the quality of life for both parents and their children. Early intervention for subsequent treatment may improve the condition and, in certain cases, serve as a satisfactory alternative for parents hesitant about further surgical intervention for their children.

New Method Using Local Affected Cartilage and Flap for the Cleft in Question Mark Ear.

BACKGROUND: As a rare auricular deformity, despite numerous surgical procedures for correcting moderate-to-severe question mark ears described in past studies, there remains a need to explore a more cost-effective approach. The optimal utilization of ear cartilage and surrounding skin while achieving superior outcomes continues to pose a significant challenge. METHODS: From 2018 to 2023, twenty-four patients with unilateral question mark ear were enrolled in this study. Seven of them were severe type deformities (absence of lower part of auricle), and seventeen were moderate (only cleft between helix and lobule). All patients were treated with new method using local cartilage and flap without damage in unaffected area. RESULTS: All patients were satisfied with significant improvement of question mark ear and the overall symmetrical appearance. The surgical scar was not obvious. No complications were observed. The follow-up period revealed that the corrective procedure kept producing the symmetrical and cosmetic results. CONCLUSION: Our new method enables optimal utilization of deformed tissue and surrounding skin, rendering this method effective and reliable for correcting moderate-to-severe question mark ears.

Retrospective study on unilateral polyotia combined with microtia utilizing the technique of preserving residual ear tissue.

BACKGROUND: The presence of polyotia in individuals with microtia is a rare deformity. Due to the intricate structure of the auricle, uncertain etiology, and challenging corrective techniques, it has always been a focal point in the field of plastic surgery. The present study presents a technique for correcting the combination of polyotia and microtia by utilizing residual ear tissue as graft material. METHODS: The retrospective study included 23 patients with polyotia and microtia from 2018 to 2022. The residual ear tissue was used to rectify auricular deformities in all patients. The patients were instructed to evaluate the satisfaction of the auricle shape using a visual analog scale (VAS) both before and 6 months after the surgical procedure. The esthetic outcomes of auricle subunits were simultaneously assessed by a senior physician pre- and postoperatively. RESULTS: The mean duration of follow-up in this study was 8.73 months. The preoperative VAS satisfaction score was recorded as 2.26 ± 0.86, while the post-operative VAS score significantly increased to 7.86 ± 0.86. The preoperative auricle esthetic outcomes score was recorded as 9.95 ± 1.74, while the post-operative score significantly increased to 24.04 ± 2.16. The follow-up period did not present any cases of flap necrosis, hematoma, infection, or wound dehiscence. CONCLUSION: The study demonstrates that comprehensive utilization of residual auricular tissue can lead to optimal outcomes in correcting polyotia with concha-type microtia. The utilization of residual ear tissue can be maximized to streamline the operation, minimize bodily harm, and enhance patient satisfaction.

The non-operative correction of ear anomalies in infants using the EarWell infant corrective system in the Netherlands.

BACKGROUND: Congenital ear anomalies are regular but often overlooked occurrences. The golden standard of treatment has been to surgically correct these anomalies at a minimum age of 5 to 7 years. As of the last century, ear molding has developed to be a safe, reliable, and effective treatment method. Different treatment methods are still under investigation. This study aims to investigate the use of the EarWell Infant Corrective System in the Dutch population. METHODS: Children aged 0-12 weeks were included in the Zuyderland Medical Center to be treated with the EarWell Infant Corrective System in case of ear deformations. Every 2 weeks, the system was replaced and correction was evaluated by both physician and parents. RESULTS: Seventy-three participants were included, of whom 123 ears in total were treated. Age at initiation was 35.5 days on average; treatment lasted an average of 59 days. Parents and physicians both reported an amelioration of all ear anomalies after treatment, scoring the correction grade an 8.8. Overall satisfaction with the treatment method was 9 or higher for both groups. CONCLUSIONS: The EarWell Infant Corrective System is a safe, reliable, and effective treatment method for the correction of ear anomalies in infants.

Modified Valente Technique for Cauliflower Ear: Outcomes in Children at Two-Year Follow-Up : New Surgical Technique for Cauliflower Ear.

BACKGROUND: Cauliflower ear deformity, a common sequela of auricular trauma, presents an esthetic and reconstructive challenge. Existing surgical techniques have limitations, including complexity, donor site morbidity, and variable long-term outcomes. MATERIALS AND METHODS: In this case series, we present a novel and minimally invasive surgical approach for the correction of cauliflower ear deformity that adapts the Valente otoplasty technique; it combines cartilage debulking with helical rim release and Mustardé mattress stitches to restore ear contour and reduce the risk of recurrence. The procedural steps include bielliptic post-auricular skin and soft tissue incision, release of the cartilaginous spring, removal of excess fibrocartilaginous tissue, cartilage reshaping with suture to restore contour, and tissue redistribution to promote adherence of skin to the cartilage framework. RESULTS: Outcomes were evaluated in 7 patients (9 ears) with cauliflower ear deformity, assessing surgical duration, complications, patient satisfaction, and esthetic outcomes at two years after surgery. The mean surgical duration per patient was 52 ± 17 minutes, including 2 bilateral procedures. Follow-up at 24 months showed favorable esthetic outcome in all patients with sustained improvements in auricular contour and symmetry with neither loss of the shape nor recurrence of deformity. Patients reported high satisfaction and improved quality of life, with mean Glasgow Children Benefit Questionnaire scores of 99.3 ± 6.3. CONCLUSIONS: This technique thus demonstrated lasting correction of cauliflower ear with favorable cosmetic outcomes, low risk of complications, and high patient satisfaction. Further investigations and longer-term follow-up are warranted to validate the technique's durability and expand its application to older and more diverse patient populations.

Prograde transposition for anteriorly low-set earlobe in lobule-type microtia reconstruction.

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.

Perioperative position management of 46 cases with simultaneous bilateral auricle reconstruction: A summary of experience.

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.

The Effects of Radial Cartilage Incision on the Growth of Rabbit Ear.

OBJECTIVES: Recently, radial cartilage incision (first-stage) at an early age combined with free auricular composite tissue grafting (second-stage) can effectively correct the concha-type microtia with the moderate or severe folded cartilage in the middle and upper third auricle, but radial cartilage incision's effects on the growth of the ear remain to be determined. The authors aimed to evaluate the effects of radial cartilage incision in young rabbits model. METHODS: Ten New Zealand white rabbits were included in our experiment. Two ears of each rabbit were divided randomly into two groups. The experimental group was operated with radial cartilage incision, and no intervention was given to the control group. The ear width, length, and perimeter were noted every two weeks. Auricular surface area was noted at 4 and 22 weeks old. The repeated measures ANOVA was used to describe ears' growth trend. A paired-sample's t test is conducted to test whether there are significant differences among the variables through the SPSS25.0 software. RESULTS: The growth tendencies of the ear length, width, and perimeter were observed and analyzed. The growth curves of the experimental ears were similar to that of the control. There was no significant difference in the increased ratio of surface area among the two groups. The cartilage of the experimental ears showed no change in biomechanical properties compared to that of control group. CONCLUSION: This study shows that radial cartilage incision at an early age does not influence the growth of rabbit ear length, width, perimeter, and surface area and also does not change the biomechanical properties of the cartilage.

Tunnelised superiorly based preauricular flap and conchal cartilage graft for antihelix reconstruction.

Reconstruction of a full-thickness defect of the auricle's anterior surface represents a challenge for plastic surgeons. This report describes the case of a man in his 70s, who underwent radical excision of a squamous cell carcinoma involving his right antihelix. We adopted an innovative approach for the reconstruction of the antihelix, using a tunnelled preauricular flap reinforced with an ipsilateral concha cartilage graft. The flap's base was de-epithelialised, allowing a single-stage procedure. Three months postoperation, no complications arose, and the scars at the donor site were effectively concealed. The aesthetic result was excellent, thanks to the perfect colour match, symmetry, shape of the auricle and the long-lasting integrity of the antihelical structure.This technique allows for accurate reconstruction of the convoluted surface of the auricle in cases of full-thickness defects of the antihelix, without the need to harvest cartilage from other donor sites and in a single surgical procedure.

A publicly available newborn ear shape dataset for medical diagnosis of auricular deformities.

Early and accurate diagnosis of ear deformities in newborns is crucial for an effective non-surgical correction treatment, since this commonly seen ear anomalies would affect aesthetics and cause mental problems if untreated. It is not easy even for experienced physicians to diagnose the auricular deformities of newborns and the classification of the sub-types, because of the rich bio-metric features embedded in the ear shape. Machine learning has already been introduced to analyze the auricular shape. However, there is little publicly available datasets of ear images from newborns. We released a dataset that contains quality-controlled photos of 3,852 ears from 1,926 newborns. The dataset also contains medical diagnosis of the ear shape, and the health data of each newborn and its mother. Our aim is to provide a freely accessible dataset, which would facilitate researches related with ear anatomies, such as the AI-aided detection and classification of auricular deformities and medical risk analysis.

Ultrasound-guided greater auricular nerve block for surgical anesthesia of the external ear.

The Greater Auricular Nerve (GAN), a branch of the cervical plexus, is used to provide anesthesia or pain relief in the ear and neck region. This case report details the use of a GAN block in a 71-year-old male patient with basal cell carcinoma on his right auricular helix. Due to multiple comorbidities (myocardial infarction resulting in a cardiac stent, hypertension), regional anesthesia was preferred. We aim to share our experience with the GAN block for ear surgery.

Brent Technique of Repair Versus Nagata Auricular Reconstruction for Microtia Reconstruction: A Systematic Review and Meta-Analysis.

BACKGROUND: Up to 17.4 in every 10,000 births are affected by microtia, but no consensus exists on a gold standard technique for autogenous repair. In this study, the authors compare 2 common methods-the Brent and Nagata autogenous costal cartilage ear reconstruction techniques. A systematic review of the literature and a quantitative meta-analysis to compare the outcomes of these 2 approaches were performed. The outcomes analyzed included rates of infection, necrosis, cartilage exposure, cartilage resorption, hematoma, wire extrusion, and hypertrophic scar. METHODS: A MEDLINE database systematic review with the following keywords: microtia, Brent, and Nagata was performed. Case reports and articles without original data or patient outcomes were excluded. Inclusion methods for study selection are outlined in Supplemental Digital Content 1, http://links.lww.com/SCS/F461 , below. The prevalence of outcomes for each study was analyzed through meta-analysis of proportions using Stata. RESULTS: A total of 536 potential studies were retrieved for review. Twelve of these studies met inclusion criteria. Four studies utilized the Brent method of repair with the inclusion of 563 ear reconstructions. Nine studies implemented the Nagata technique in 2304 reconstructions. Two studies directly compared the Brent (327 ears) and Nagata (471 ears) techniques. The calculated rate and 95% confidence intervals are summarized in Supplemental Digital Content 2, http://links.lww.com/SCS/F461 . There were no statistically significant differences in complication rates between the Brent and Nagata microtic reconstruction techniques identified in this study. CONCLUSIONS: The Brent and Nagata microtia reconstruction techniques have no difference in the risk of infection, necrosis, cartilage exposure, cartilage resorption, hematoma, wire extrusion, or hypertrophic scars.

Reconstruction of Upper Third Defect of the Auricle by Conchal Cartilage Graft and Coverage by Postauricular Flap.

BACKGROUND: The defects of the upper third of the auricle are considered significant reconstructive challenges, as they require frequent operations with a high risk of morbidity at the donor site and result in unacceptable cosmetic abnormalities. OBJECTIVE: Is to perform the reconstruction of a full-thickness auricular defect located in the upper third of the ear using a conchal cartilage graft with postauricular flap coverage, aiming to minimize both donor and recipient morbidity. PATIENTS AND METHODS: The current study included 20 patients with unilateral upper-third auricular defects. The repair involved 2 components: a cartilage graft from the concha to provide structural support and a flap for coverage. Follow-up was conducted for 6 months after the operation. RESULTS: Successful outcomes were achieved in both subjective and doctors' assessments. Regarding subjective outcomes, 85% of the patients reported high satisfaction (P < .001). In terms of doctors' subjective assessment, 90% of the patients had excellent results (P < .001). Mild early and postoperative complications, if encountered, resolved spontaneously. CONCLUSION: The use of a combined conchal cartilage graft and postauricular flap in treating a full-thickness upper third auricular defect is safe and effective, with no major complications. The technique preserves the cosmetic and functional outcomes of the auricle, providing an excellent color match and minimal donor-site morbidity.

Long-Term Effectiveness of Ear Molding and Factors Affecting Outcomes.

BACKGROUND: The EarWell System offers a correction opportunity for infants born with ear anomalies. However, the long-term effectiveness of ear molding remains unclear. This study aimed to explore the long-term effectiveness of this novel technique and to determine the risk factors for recurrence. METHODS: This retrospective, population-based cohort study was performed from 2017 through 2021. Infants who completed ear molding therapy and were followed up for longer than 6 months were enrolled. The main outcomes were immediate and long-term efficacy, which were graded by two blinded plastic surgeons. RESULTS: A total of 226 infants (334 ears) were recruited. The most common anomalies were helical deformities [113 ears (33.8%)], and the rarest were cryptotia [five ears (1.5%)] and conchal crus [five ears (1.5%)]. The age at initiation of treatment was a factor affecting both immediate ( P = 0.004) and long-term effectiveness ( P = 0.009). The type of anomaly also influenced long-term molding outcomes. For cup ears, the success rate of long-term outcomes (76.0%) was significantly lower than that of immediate outcomes (98.7%) ( P < 0.001). Prominent ear, cup ear, and microtia were found to be the most likely to relapse during long-term follow-up. The results of logistic regression also demonstrated age, duration time, and the type of anomaly to be risk factors of ear molding effects. CONCLUSIONS: The EarWell System was shown to be a secure and effective method for treatment of congenital ear anomalies. Some infants' ear anomalies recurred after successful immediate results. The age at initiation of treatment and the type of anomaly were predictors of long-term outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.
