The Protruding Ear: Cosmetic and Reconstruction

Aesthetic Auricle Reconstruction with the Dieffenbach Flap: A Retrospective Case Review

The Dieffenbach flap is often used for post-Mohs reconstruction of auricle defects, effectively restoring the auricle rim. However, its impact on auricle projection and length after division and inset is not well-documented. This study evaluates auricle projection and length following defect repair with the Dieffenbach flap, comparing results to the nonoperative ear. We conducted a retrospective review of patients who underwent a Dieffenbach flap repair surgery at a single institution from 2016 to 2023. Auricle projection and length of the reconstructed ear were measured within the first month following division and inset of the flap and compared with the contralateral ear. A subset of patients had additional measurements > 1 month following division and inset, and these measurements were compared with the contralateral ear. Our study included 23 patients with an average age 67.4 years and 78.3% male. Within 1 month following division and inset, the Dieffenbach flap resulted in a significant decrease in auricle projection (16.5 vs. 18.6 mm, p < 0.05) and length (67.0 vs. 69.7 mm, p < 0.05) compared with the contralateral ear. Subsequent follow-up showed no significant differences in projection (18.5 vs. 18.5 mm, p = 0.98) or length (68.0 vs. 68.7 mm, p = 0.54). Following division and inset of the Dieffenbach flap, auricle projection and length experience initial reduction but subsequently self-correct to match the contralateral ear.

"Inside-out" otoplasty in school-age children: Clinical and aesthetic results

AIM

Prominent ears are a common congenital deformity that can cause significant psychological distress, especially in school-age children. This study aims to evaluate the clinical and aesthetic outcomes of the ''inside-out'' otoplasty technique in addressing prominent ears in children aged 7 to 17.

METHODS

A retrospective review was conducted on 20 children (5 boys, 15 girls) who underwent bilateral ''inside-out'' otoplasty. Postoperative outcomes were evaluated at one year using the Global Aesthetic Improvement Scale (GAIS) and Visual Analog Scale (VAS) to assess clinical success and parental satisfaction. The procedure focused on reshaping the ear cartilage internally and externally to form natural helical and antihelical folds.

RESULTS

Among the 20 patients, 60 % were rated as "very much improved" on the GAIS scale, 30 % as "much improved," and 10 % as "improved." No cases of "no change" or "worse" were observed. Additionally, 95 % of parents reported being "very" or "completely" satisfied with the appearance and symmetry of their children's ears, reflecting a high level of aesthetic and clinical success. Visual Analog Scale (VAS) scores demonstrated significant satisfaction, with all patients scoring between 1 and 3, further confirming the positive clinical and psychological outcomes of the ''inside-out'' otoplasty technique.

CONCLUSION

The "inside-out" otoplasty technique effectively corrects prominent ears in school-age children, providing aesthetic and psychological benefits. Early intervention improves ear appearance, boosts social integration, and enhances self-confidence. The procedure is safe and does not impact ear growth, making it a valuable early treatment option for children with prominent ears.

Partial Cutting Otoplasty: A Stable Technique for Prominent Ears

Prominent ears are a common deformity that can cause significant social and psychological distress, especially at a young age. Otoplasty changes the shape and, in some cases, the size of the ear, by working on two crucial points of the anatomy: the hypertrophy of the conchal bowl and the undeveloped antihelix fold. Generally speaking, there are two main approaches to auriculoplasty: cartilage cutting and cartilage sparing techniques; cartilage sparing techniques are safer but with limited aesthetic results. Despite the simplicity of this surgery, complications such as irreversible distortion of the anatomy, overcorrection, or recurrence are very frequent and have important consequences for facial aesthetics. A novel technique based on the perfect equilibrium between cartilage sparing and cartilage cutting technique is described. This method is based on three to four mattress sutures that reshape the antihelix, with a limited component of cartilage cutting and excision of the overdeveloped concha, avoiding high-tension sutures and scarring on the anterior surface of the ear. This technique was used on 150 ears from 2019 to 2023, with only three ears (2%) requiring revision. Rates of complications or recurrence were low. The presented technique appears to be a rapid, reproducible, and safe method for treating the prominent ear deformity, providing aesthetically pleasing results.

Otoplasty in Saudi Arabia: Is There a Change in Demographic Trend?

Background

Prominent ears are a recognized ear deformity. Surgical correction of prominent ears aims to improve quality of life, particularly in children before school entry. This study examines patient demographics and surgical practices in otoplasty in Saudi Arabia, comparing findings with international trends.

Methods

An online cross-sectional survey of plastic surgeons and otolaryngologists in Saudi Arabia was conducted. The questionnaire comprised sociodemographic data, otoplasty practice questions, and questions about the demographics of patients presenting with otoplasty from the surgeon's perspective.

Results

A total of 155 respondents participated in the study, of whom 60.6% were plastic and reconstructive surgeons, and 49.7% of surgeons reported 5-6 years of age as the optimum timing for otoplasty. The Mustardé technique was the most chosen technique (35.3%). Additionally, 43.2% of surgeons stated that patients in the 6- to 12-year age group were the typical age group that presented with prominent ears seeking treatment. Aesthetic complaints were the most common reason (64.5%) for referral to the clinic. Moreover, the optimum timing of otoplasty was significantly associated with age of patients undergoing otoplasty (P = 0.043).

Conclusions

The study's findings offered significant insights into the existing practices of otoplasty in Saudi Arabia and emphasized prospective areas that warrant future exploration.

Bat Ear Correction Steps and Outcomes for Better Life Support

An unusually projecting human ear is known as a prominent ear, otapostasis, or bat ear. It might be both bilateral and unilateral. The scapha and antihelix of the big concha are not well formed. It is the outcome of cartilage deformity that occurred during early ear development in utero. After the child reaches five years old, the abnormality can be corrected at any time. In order to prevent psychological suffering, the procedure should ideally be performed as soon as possible. Otoplasty correction is reshaping the ear cartilage to bring the ear closer to the side of the head. The cartilage is reshaped, but the skin is left in place. Hearing remains unaffected by the operation. It is mainly done for aesthetic reasons. Although they are uncommon, the post-operative consequences from the operation include hematoma development, keloid formation, infection, and asymmetry in the ears. Otoplasty is a cosmetic operation that involves permanent sutures to alter the size, shape, or location of the ear. The main purpose of otoplasty is to treat promin auris, or bulging ears. Promin auris, the principal indication for otoplasty, is the subject of this review. The indications, contraindications, and method utilized in otoplasty are reviewed in this exercise, which also emphasizes the need of pre- and post-operative care for patients having this surgery. Otoplasty results are generally lifelong and will improve the self-confidence. The goals of otoplasties are to make the ears appear more natural in comparison to the head and help with the overall contour of the ears. Final ear surgery results will be visible after a two week recovery period, with small improvements appearing for up to 12 months post-procedure. A proper understanding of the diagnosis, indications, and surgical techniques will lead to positive outcomes in otoplasty.

Cartilage-sparing otoplasty - 288 ears in 3 years

BACKGROUND

Standard methods of otoplasty may risk anatomical distortion. Previous work showcased a novel, cartilage-sparing technique. This study aimed to confirm the safety and effectiveness of the method in a larger cohort.

METHODS

This retrospective study included patients undergoing otoplasty by a single surgeon using a single technique between January 2021 and December 2023. Eligible patients were aged >5 years and had prominent or constricted or cup ears, forming a 2 cm distance from the mastoid. Surgical techniques included novel key-point sutures. Minimum follow-up was 6 months. Data on demographics, risk factors, perioperative management, and complications were collected from patient records.

RESULTS

A total of 288 operated ears (147 patients) were included. The mean age was 17 years, and 91 (61.9%) were female. The mean duration of follow-up was 24.3 months. Postoperative complications were generally minor and included Polydioxanone (PDS) suture exposure (n = 16, 5.5%), manageable postoperative pain (n = 8, 2.7%), self-resolving swelling (n = 8, 2.7%), minor bleeding (n = 7, 2.4%), and superficial skin complications (n = 4, 1.3%). Infections occurred in 4 ears (1.3%) and were treated effectively with topical/oral antibiotics. Cases of partial release of the ear resolved without intervention (n = 4, 1.3%). Only 4 (1.3%) ears experienced loss of correction, with options for reoperation available as needed. Analysis showed no significant age differences in postoperative complications and a nonsignificant trend towards higher postoperative swelling in males than in females (10.7% vs 2.2%; P = 0.054).

CONCLUSIONS

The data confirms that this technique offers safe and rapid cartilage-sparing otoplasty with minimal complications and low recurrence rates. It ensures long-lasting and aesthetically pleasing results for prominent ear deformities.

A Retrospective Analysis of Pinnaplasty Outcomes: The Welsh Experience

Prominent ears (PEs) are the most frequent congenital external ear deformity, occurring in ∼5% of the population. Although the deformity does not usually cause functional difficulties, it can significantly affect the patient's psychological and social health. The authors aim to present the Welsh experience of pinnaplasty, reviewing our outcomes and complications. A retrospective cross-sectional study was performed of all patients undergoing pinnaplasty in Morriston Hospital, Swansea, Wales. We represent the tertiary plastic surgery referral unit across Wales. We included all patients undergoing pinnaplasty between 2015 and 2022 inclusive. We excluded patients undergoing revision procedures or those who had no follow-up. Over the 7-year period, 236 pinnaplasties were performed and 203 were included in the analysis. Ninety-six percent of cases were performed using a cartilage-sparing approach, which represents the mainstay in our unit. The mean follow-up length for our cases was 12 months. Revision procedures were required in 4% of cases. Three hematomas (1.5%) and one (0.5%) wound dehiscence due to infection were recorded and required a return to the operating room. Suture extrusion was noted in 5% of cases (10 patients); 4.5% (9) cases were affected by either hypertrophic or keloid scarring. Across the United Kingdom, cosmetic procedures have come under scrutiny, namely, because of a difficult economic climate. In the era of tight fiscal control in health care, it is pertinent to analyze the outcomes and performance metrics of our operations regularly, thus aiding in the development of an established evidence base to advocate for our respective patients.

A Technique of Autologous Costal Cartilage Graft Combined With Auricular Cartilage Folding to Correct Question Mark Ear in a Single Procedure

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.

Correction of Lying Ear and Aesthetic Modification of Helix and Ear Lobule With Hyaluronic Acid Filler Injection: Experience in Chinese Patients

BACKGROUND

Large and long ears are regarded as symbols of wealth and health in East Asian culture, and people with lying ears often want their ears to be more exposed and prominent. Surgeries to correct lying ears have been documented.

OBJECTIVES

The aim of this study was to report the correction of lying ears and the aesthetic modification of helix and ear lobule with hyaluronic acid (HA) injections.

METHODS

HA injections were performed at the auriculocephalic sulcus to increase the cranioauricular angle (CA) and correct lying ears. The injections at helix and lobule were case specific. The CA was measured and photographs were taken at baseline and at 1-, 3-, 6-, and 10-month follow-ups. Efficacy was assessed with the 5-point Global Aesthetic Improvement Scale (GAIS). Adverse events were recorded.

RESULTS

Forty-six patients (92 ears) received HA injections and completed follow-ups. Instant correction outcomes were observed. Sixteen (34.8%) patients received 1 touch-up injection, the clinical efficacy of which persisted for 1 to 1.5 years. For over 90% of cases with touch-up treatment the GAIS was "very much improved" or "much improved" at all follow-ups. The GAIS for over 70% of cases without touch-up treatment was "very much improved" or "much improved" at 1-, 3-, and 6-month follow-ups. CA increased significantly compared with the baseline. Patients also reported "more V-shaped face shape" and "lifted jawline" effects. No serious adverse events occurred.

CONCLUSIONS

As an alternative technique to surgeries, HA filler injections at the auriculocephalic sulcus effectively corrected lying ears. This technique produced immediate, long-lasting, and aesthetically pleasing results. The side effects and downtime were minimal.

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.

A Different Approach for Protruding Earlobe Correction-Modified Fish-tail Technique

BACKGROUND

Protruding ears are the most common auricular abnormalities seen in children (1). Protruding ears are a condition that has social and psychological consequences due to its physical appearance and one of the main causes of peer bullying at young ages (2). While various surgical methods exist to address prominent ears, the options for correcting the lobule are relatively scarce. In this study, we are aimed to present the modified fish-tail technique that we have developed and to compare it with other techniques in the literature.

METHODS

The patients were selected from the cases that underwent otoplasty for prominent ear correction in our clinic between 2020 and 2022. A total of 21 cases that required protruded lobule correction during otoplasty were included in our study. Keloid and hypertrophic scar formation, wound dehiscence, hematoma, infection and recurrence in the lobule were evaluated. The patients were followed up for at least 1 year for early and late complications.

RESULTS

Each patient in the study underwent bilateral prominent ear correction, including bilateral modified fish-tail technique. All cases were followed for at least 12 months. There was no wound dehiscence, infection, recurrence in lobule prominence or hematoma during the follow-up period. No hypertrophic scar or keloid was observed in any case.

CONCLUSIONS

Our method stands out for its ability to achieve both adjustable vertical height and effective lobule correction with a reduced need for skin excision. We recommend the modified fish-tail technique as an alternative technique for prominent lobule surgery.

Objective evaluation of nonsurgical treatment of prominent ears: A systematic review

Background

The prominent ear is a type of congenital ear deformity that can be corrected by a variety of nonsurgical treatments, such as splinting and the taping method. However, there is no objective evaluation method that is universally accepted. The aim of this review is to evaluate objective measurement methods that are used in the available literature to analyze nonsurgical treatment of prominent ears.

Methods

A systematic review was performed in the MEDLINE and Embase databases in December 2022 and updated on April 2023 according to Preferred Reporting Items for Systematics and Meta-Analyses (PRISMA) guideline. Any study using objective measurements (continuous variables such as distance and angle) to evaluate the effect of nonsurgical treatment of prominent ears was included. The Joanna Briggs Institute (JBI) critical appraisal for case series was used for quality assessment.

Results

A total of 286 studies were screened for eligibility, of which five articles were eligible for inclusion. All of the included studies were case series. The helix mastoid distance (HMD) is the most commonly used parameter to measure treatment outcome. Pinna and cartilage stiffness, length, and width were also used, but without clear statistical relevance. HMD was classified into grading groups (i.e. good, moderate, and poor) to evaluate the treatment's effect.

Conclusion

Based on the included studies, objective measurements are rarely used, and when used, they are largely heterogeneous. Although HMD was the most frequent measurement used, all studies used different definitions for the measurement and grouped subsequent outcomes differently. Automated algorithms, based on three-dimensional imaging, could be used for object measurements in the nonsurgical treatment of prominent ears.

Seminars in Plastic Surgery: Pediatric Ear Anomalies and Reconstruction

Congenital ear anomalies affect 15 to 20% of neonates and can be categorized as either auricular deformations or malformations. Deformations involve a fully developed, albeit abnormally shaped, chondrocutaneous framework, which makes them amenable to correction with ear molding within the first few months of life. Malformations involve hypoplastic or fully absent auricular structures that require augmentation with alloplastic and/or autogenous reconstruction. The goal of this article is to outline the various auricular deformities and malformations, followed by a description of the latest clinical management options, both nonsurgical and surgical, by auricular anomaly.

The role of MRI in the prenatal diagnosis and classification of fetal microtia

OBJECTIVE

To investigate the role of MRI in the diagnosis and classification of fetal microtia.

METHODS

Ninety-five fetuses with suspected microtia based on ultrasound and MRI performed within 1 week were enrolled in this study. The diagnosis based on MRI was compared with postnatal diagnosis. Among the microtia cases suspected on the basis of MRI, mild and severe cases were further classified. In addition, external auditory canal (EAC) atresia was evaluated by MRI in 29 fetuses with a gestational age > 28 weeks, and the accuracy of MRI in the diagnosis and classification of microtia was determined.

RESULTS

Of 95 fetuses, 83 were considered to have microtia on the basis of MRI, 81 were confirmed to have microtia, and 14 were found to be normal according to postnatal diagnosis. Among 190 external ears in 95 fetuses, 40 ears were suspected to have mild microtia, and 52 ears were suspected to have severe microtia on the basis of MRI. According to the postnatal diagnosis, mild and severe microtia were confirmed in 43 and 49 ears, respectively. Among the 29 fetuses with a gestational age > 28 weeks, 23 ears were suspected to have EAC atresia according to MRI and 21 ears were ultimately confirmed to have EAC atresia. The accuracy of MRI in diagnosing microtia and EAC atresia was 93.68% and 93.10%, respectively.

CONCLUSION

MRI shows good performance in diagnosing fetal microtia and has the potential to evaluate its severity on the basis of classification and EAC status.

CLINICAL RELEVANCE STATEMENT

This study was aimed at investigating the role of MRI in the diagnosis and classification of fetal microtia. MRI shows good performance and can help evaluate microtia severity and EAC atresia, thus allowing for better clinical management.

KEY POINTS

• MRI is a useful adjunct to prenatal ultrasound. • MRI has a higher accuracy rate than ultrasound in diagnosing fetal microtia. • The accurate classification of fetal microtia and the diagnosis of external auditory canal atresia through MRI may help guide clinical management.

Cartilage-Sparing Otoplasty: A New Approach

SUMMARY

Ear protrusion is the primary indication for otoplasty. Many methods have been developed for addressing this defect, based on cartilage-scoring and excision and suture-fixation techniques. Disadvantages include irreversible distortion of the anatomy, irregularities, or overcorrection, or forward bulging of the conchal bowl. One of the most common long-term sequelae of otoplasty is an unsatisfactory result. A novel, cartilage-sparing, suture-based technique has been developed that aims to minimize the risk of complications and provide a natural-appearing aesthetic result. The method is based on two to three key sutures that shape the concha into the desired natural appearance while preventing a conchal bulge, which otherwise could appear if no cartilage is removed. Furthermore, these sutures support the neo-antihelix created by four further sutures anchored to the mastoid fascia, thus achieving the two main goals of otoplasty. The sparing of cartilaginous tissue means that the procedure is reversible if needed. In addition, permanent postoperative stigmata, pathologic scarring, and anatomical deformity can be avoided. This technique was used on 91 ears in 2020 and 2021, with only one ear (1.1%) requiring revision. Rates of complications or recurrence were low. The presented technique appears to be a rapid and safe method for treating the prominent ear deformity, providing aesthetically pleasing results.

Auricular Protrusion After the Postauricular Approach: A Review of the Current Literature

The postauricular approach is a widely adopted surgical technique for the ear due to its unique access to the middle ear, mastoid, and other internal structures, while adeptly concealing the surgical incision for aesthetic superiority. Despite its advantages, concerns have emerged regarding the potential for auricular protrusion following the procedure. While the exact mechanisms underlying this phenomenon remain under debate, it is worth noting that comprehensive literature on this topic is scant. Nevertheless, available studies predominantly indicate no association between the postauricular approach and lasting auricular protrusion. In the few reports that do note its occurrence, the protrusion appears transient, resolving over time. These findings suggest that surgeons should continue using the postauricular approach without concerns regarding auricular protrusion. Nonetheless, it is recommended to take all precautionary measures, including appropriate patient selection, engagement of an experienced surgeon, and meticulous postoperative dressing.

Advantages of the Cartilage-Sparing Technique in Prominent Ear Deformity Surgery: Comparison of a New Technique

OBJECTIVE

Ear cartilage, crucial for maintaining ear shape and function, can sometimes undergo damage or deformation, requiring surgical intervention. This study aimed to compare the efficacy of a novel, less invasive cartilage-protective method with the traditional, more invasive cartilage-removal technique.

METHODS

Our study included 64 patients (128 ears). The first group of 32 patients (64 ears) received the new cartilage-protective technique, while the second group of an equal number of patients and ears underwent the traditional method. The newer technique endeavors to retain as much healthy cartilage as possible, addressing only the issue at hand, while the traditional technique requires the removal of a substantial portion of cartilage.

RESULTS

The cartilage-protective method demonstrated several notable advantages over the traditional one. First, it significantly reduced the operation duration due to its less invasive nature. Second, it caused less pain to the patients by minimizing trauma to surrounding tissues. Furthermore, this technique significantly lowered the risk of complications, probably due to the minimal disturbance or removal of healthy cartilage, hence reducing the likelihood of post-operative complications such as infections or deformities.

CONCLUSION

The findings of our study propose the cartilage-protective method as a superior treatment option when surgical intervention becomes necessary to repair or restore the function of ear cartilage. This technique, being less invasive, not only results in less pain for the patients but also reduces the risk of complications. It promotes quicker patient recovery without any loss of sensation in the ear. Thus, it could potentially revolutionize the approach to dealing with ear cartilage issues.

Arcade Sutures to Minimize Ear Displacement in Rhytidectomy

Ear deformities after rhytidectomy are not uncommon and have a significant impact on cosmetic success. We postulate the use of horizontal mattress suspension sutures in the anterior face anchored to the deep temporalis fascia (DTF) during rhytidectomy allows for a vertical lift while minimizing the risk to the frontal branch of the facial nerve and decreasing forward rotation of the ear. To compare auricular displacement during rhytidectomy using an arcade of horizontal mattress suspension sutures anchored to the DTF instead of the preauricular pre-parotid fascia, and evaluate outcomes with this modification at 1 year. This was a proof of concept prospective cohort study of 20 patients (40 sides) undergoing rhytidectomy by a single plastic surgeon (level of evidence 4). Intraoperative measurements were taken to determine the amount of auricular displacement with suspension sutures placed in the preauricular fascia compared with the DTF. To confirm longevity, we compared ear position preoperatively and at 1 year after rhytidectomy with our technique. There was significantly less auricular displacement when superficial musculoaponeurotic system (SMAS) suspension sutures were placed in the DTF 0.75 ± 0.69 mm compared with the preauricular fascia 9.71 ± 2.57 mm (p < 0.00001). With our technique at an average follow-up of 370.3 days, there was no significant change in auricular rotation compared with preoperative photos (p = 0.125).Our simple rhytidectomy modification allows for vertical resuspension of the SMAS in the anterior face in a safe manner while minimizing displacement of the auricle.

Correction of Darwin's Tubercle with Plasma Exeresis

Darwin’s tubercle (DT) is a congenital outer ear deformity characterized by a posterior thickening of the auricular helix. It is particularly common in certain ethnic groups, with reports ranging between 10% and 58% of the specific populations. Despite being common, this vestigial trait is poorly known. It carries no clinical significance, except in the cases where it might be hypertrophic, potentially causing psychological distress and significant social impairment. DT has been traditionally treated with surgical resections where part of the helical cartilage is removed. More recently, cartilage reshaping has been envisioned without cutting, suturing, or scars, using laser irradiation. Surgical resection, laser ablation and plasma exeresis are different tools in the surgeon’s armamentarium which may all be used successfully. Nevertheless, the first may cause noticeable scarring while the second may cause relevant laser-related complications. We present a noninvasive aesthetic medicine procedure based on plasma exeresis, which combines the benefits of a noninvasive procedure with the advantage of not requiring lasers for the correction of this cartilage defect. We present the case of a 28-year-old woman with right-sided hypertrophic DT, who requested a correction of the outer ear deformity. Two sessions were required, pain intensity during treatment was low, no complications were reported, and the patient was satisfied with the result at 6 months from the last session. Although plasma exeresis has been described in the past for several other non-invasive procedures of the skin, this is the first report of its kind for the correction of minor cartilage reshaping.

Local estrogen for nonsurgical recontouring of auricular cartilage

INTRODUCTION

5% of children are born with auricular deformities. Permanent recontouring can be achieved through splinting during early infancy. Beyond this time, splinting is ineffective, and patients require surgical correction. Neonatal cartilage malleability is hypothesized to be secondary to retained maternal estrogens, increasing hyaluronic acid concentration. In this article, we evaluate the efficacy of local estrogen treatments for the nonsurgical recontouring of mature auricular cartilage.

METHODS

Ears of New Zealand rabbits were folded and splinted and then were randomly assigned to an experimental group, n = 10 (injected estrogen, topical estrogen, saline, or untreated). Treatment ears received injected estrogen or saline twice weekly or topical estrogen daily for 4 weeks. Two weeks post-treatment, splints were removed, and ear angles were measured. Biopsies were taken for histologic and mechanical analysis, and systemic estrogen levels were assayed.

RESULTS

Ear angles stabilized by 9 days post-splinting. Topical estrogen led to a significantly smaller resting angle (121.6° ± 13.5°) compared with saline and control (135.9° ± 11.2° and 145.3° ± 13.0°, respectively). Injected estrogen led to the most pronounced angle decrease (64.5° ± 35.3°). Ears injected with estrogen also showed a significant increase in cartilage thickness. Hyaluronic acid concentration was increased in both estrogen treatment groups compared with saline. At 3 weeks post-treatment, there was no significant differences in the elastic modulus of the cartilage or serum estrogen levels among the groups.

CONCLUSION

Results show the potential result of local estrogen treatment to achieve a stable nonsurgical remodeling of mature auricular cartilage. Further study is needed to evaluate the molecular mechanism and improve the transdermal estrogen delivery to optimize treatment regimen.

Tissue engineering of human ear pinna

Auricular deformities (Microtia) can cause physical, social as well as psychological impacts on a patient's wellbeing. Biofabrication of a complex structure such as ear pinna is not precise with currently available techniques. These limitations can be overcome with the help of tissue engineering. In this article, the authors presented molding and three dimensional (3D) printing to generate a flexible, human size ear pinna. The decellularization of goat ear cartilage protocol and bioink alkaline digestion protocol was followed to yield complete removal of all cellular components without changing the properties of the Extra Cellular Matrix (ECM). Decellularized scaffold used in molding technology and 3D printing technology Computer-Aided Design /Stereolithography (CAD/STL) uses bioink to construct the patient-specific ear. In vivo biocompatibility of the both ear pinnae showed demonstrable recellularization. Histology and scanning electron microscopy analysis revealed the recellularization of cartilage-specific cells and the development of ECM in molded and 3D printed ear pinna after transplantation. Both the techniques provided ideal results for mechanical properties such as elasticity. Vascular Associated Protein expression revealed specific vasculogenic pattern (angiogenesis) in transplanted molded pinna. Chondrocyte specific progenitor cells express CD⁹⁰⁺ which highlighted newly developed chondrocytes in both the grafts which indicated that the xenograft was accepted by the rat. Transplantation of molded as well as 3D ear pinna was successful in an animal model and can be available for clinical treatments as a medical object to cure auricular deformities.

Prominent Ear Correction Using Full-Thickness Cartilage Strip: An Incomplete Cutting Technique

BACKGROUND

Prominent ears are one of the most well-known facial disfigurements influencing youngsters. Approximately 5% of the population suffers from some degree of ear prominence. More than 200 techniques have been used for the surgical correction of prominent ears, referring that no single "best" method exists and that techniques and modifications will continue to appear.

OBJECTIVES

In this work, we are going to evaluate the results of using a full-thickness cartilage strip, an incomplete cutting technique for the correction of various degrees of the prominent ear.

PATIENTS AND METHODS

This prospective controlled clinical trial was carried out on a sum of 63 patients, who presented with prominent ear deformity, in the period between March 2014 and January 2020 at the plastic and reconstructive surgery department, Tanta University Hospitals, and private clinic.

RESULTS

Sixty-three patients were operated upon, 46 were males and 17 were females, their age ranged between 4 and 23 years, and their mean age was 9.7 years. Clinical results showed excellent results in 37 patients (58.7%), good results in 18 patients (28. 6%), fair results in 8 patients (12.7%), and no poor results. Patient satisfaction showed excellent results in 32 patients (50.8%), good results in 22 patients (34.9%), fair results in 9 patients (14.3%), and no poor results.

CONCLUSIONS

Prominent ear correction using full-thickness cartilage strip, an incomplete cutting technique, is a good technique. It can be used in the correction of different varieties of prominent ears. It has a very low incidence of complications. No hypertrophic or keloidal scars have been reported.

Tissue Engineering the Pinna: Comparison and Characterization of Human Decellularized Auricular Biological Scaffolds

Decellularization is one of the promising techniques in tissue engineering used to create a biological scaffold for subsequent repopulation with the patient's own cells. This study aims to compare two different decellularization protocols to optimize the process of auricle decellularization by assessing and characterizing the decellularization effects on human auricular cartilage. Herein, 12 pairs (8 females, 4 males) of freshly frozen adult human cadaveric auricles were de-epithelialized and defatted leaving only the cartilaginous framework. An auricle from each pair was randomly assigned to either protocol A (latrunculin B-based decellularization) or protocol B (trypsin-based decellularization). Gross examination of the generated scaffolds demonstrated preservation of the auricles' contours and a change in color from pinkish-white to yellowish-white. Hematoxylin and eosin staining demonstrated empty cartilaginous lacunae in both study groups, which confirms the depletion of cells. However, there was greater preservation of the extracellular matrix in auricles decellularized with protocol A as compared to protocol B. Comparing protocol A to protocol B, Masson's trichrome and Safranin-O stains also demonstrated noticeable preservation of collagen and proteoglycans, respectively. Additionally, scanning electron micrographs demonstrated preservation of the cartilaginous microtopography in both study groups. Biomechanical testing demonstrated a substantial decrease in Young's modulus after decellularization using protocol B (1.3 MPa), albeit not significant (P-value > 0.05) when compared to Young's modulus prior to decellularization (2.6 MPa) or after decellularization with protocol A (2.7 MPa). A DNA quantification assay demonstrated a significant drop (P-value < 0.05) in the DNA content after decellularization with protocol A (111.0 ng/mg) and protocol B (127.6 ng/mg) in comparison to before decellularization (865.3 ng/mg). Overall, this study demonstrated effective decellularization of human auricular cartilage, and it is concluded that protocol A provided greater preservation of the extracellular matrix and biomechanical characteristics. These findings warrant proceeding with the assessment of inflammation and cell migration in a decellularized scaffold using an animal model.

Otoplasty through Ventral Skin Incision and Shaping of the Antihelix by Abrasion-A Retrospective Study

(1) Background: Protruding ears are the most common auricular malformation affecting approximately 5% of the population. One common factor leading to auricular protrusion is a deficiency or total absence of the antihelix. A technique first described by Gottfried Lemperle in 2003 attempts cartilage thinning, folding, and fixation by non-absorbable mattress sutures after ventral skin incision along the ventral helical rim. (2) Methods: Retrospective analysis of patient records was performed for otoplasties according to this technique, performed between 1985 and 2014 at Agaplesion Markus Hospital in Frankfurt, Germany. All recorded complications were examined. (3) Results: A total of 912 single otoplasties were performed according to this technique from 1985 to 2014. Overall complications included 26% minor complications not requiring further surgery and 11% major complications leading to revision surgery. Within those requiring revision surgery, the most common reason was recurrence of auricular protrusion (5%), followed by suture granulomas (5%) and hematomas (2%). (4) Conclusions: Lemperle’s otoplasty technique addresses the open thinning and shaping of the antihelix through a ventral incision along the helix to prevent irregularities and possible ridges. Results show a low complication rate comparable to data found in published studies. This technique is easy to perform, safe, and avoids often seen contour irregularities of the antihelix compared to techniques with a posterior approach.

Prospective Evaluation of Psychological Healing in Adults Who Underwent Otoplasty for Prominent Ear

BACKGROUND

Otoplasty is performed to heal the psychological discomfort caused by the appearance of prominent ear by bringing the ear to its anatomical position. However, there have been few studies with limited numbers of patients that have prospectively evaluated psychosocial recovery following otoplasty in adults. The purpose of this prospective study was to evaluate the versatile psychological recovery that can be achieved in adults following otoplasty.

METHODS

In this prospective cohort study, a single-group, pretest-posttest model was used as the experimental research model. Patient satisfaction status was measured, and the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory I-II (STAI I-II), Rosenberg Self-Esteem (RSES), and Body Cathexis Scale (BCS) tests were performed on patients before and after surgery.

RESULTS

A total of 66 patients with a mean age of 20.7 ± 3.1 years, 66.7% of whom were women, were included in the study. While 97% of the patients were satisfied with the results of the operation, 3% were undecided. The mean values of the BDI, STAI-I, STAI-II, and BCS before and after surgery were 11.4 ± 5.7, 40.9 ± 6.7, 43 ± 9.4, 74.2 ± 20.5, and 8.5 ± 5.5, 38.6 ± 7.4, 39.5 ± 9.2, 63.5 ± 17.6, respectively. While the proportion of patients with a high RSES score before surgery was 42.42%, the proportion after surgery was 96.96%. The differences in the mean scores of all tests before and after surgery were also statistically significant (p < 0.05).

CONCLUSION

Our study demonstrated that otoplasty made positive contributions to body perception, self-esteem, anxiety, and depression in adults. Otoplasty is as beneficial in adults as it is in pediatric patients.

Postcode lottery? Do clinical commissioning groups differ in their funding of prominent ear correction surgery

In 2013 Clinical Commissioning Groups (CCGs) were created and became responsible for the planning and commissioning of health care services in their area. The Royal College of Surgeons and the British Association of Plastic, Reconstructive and Aesthetic Surgeons created guideline for the CCGs in 2013 for the surgical treatment of prominent ears. By looking at each of the CCGs’ websites, we aim to review their equity and how well they adhere to standards to determine whether there is a regional variation for funding of this procedure.

We found that 47% of the CCGs will fund this procedure only on an exceptionality basis, compared to 26% who had set criteria and would allow funding if these criteria were met. There was significant variation in the age at which funding would be considered with some CCGs allowing funding from 5 years of age and others not providing it until as old as 11 years. Only 11 policies made any reference to cartilage moulding and only 3 mentioned funding to allow correct fitting of hearing aids.

Unfortunately, despite recommendations from the Royal College of Surgeons and the British Association of Plastic and Reconstructive Surgery, there is still variation in funding criteria between CCGs for correction of prominent ear surgery. This may result in patients being treated differently depending on their postcode. We would urge commissioners to apply more consistent and uniform guidelines for the funding of surgical correction of prominent ears.

Refinements in Otoplasty Surgery: Experience of 200 Consecutive Cases Using Cartilage-Sparing Technique

BACKGROUND

Many techniques have been described to correct prominent ears, including cartilage-suturing, cartilage-scoring, and cartilage-breaking techniques. Understanding the topography and anatomy of the auricular cartilage is crucial for performing safe otoplasty with consistent results.

METHODS

Two hundred consecutive patients with prominent ears were operated on using a modified Mustardé and Furnas technique with some refinements and without performing any cartilage scoring or excision. Adequate dissection and exposure of cartilage and precise repositioning of the tail of helix (cauda helicis) are keys to correction of lobule prominence without the need for any adjunctive procedures such as skin excision from the back of the lobule or suture fixation of the lobular tissues to the concha, mastoid, or scalp. Detailed description of the technique and review of the complications are presented.

RESULTS

This suturing-only technique had a low complication rate. Hematoma occurred in two patients only. Skin necrosis and wound dehiscence were not reported in any patient. Suture extrusion was the most common complication and was easily managed, mostly in the clinic. Relapse of deformity needing surgical correction occurred in eight cases.

CONCLUSIONS

The series demonstrates that most of the potential complications of otoplasty can be avoided and favorable results can be obtained by paying attention to the anatomical details of the deformity and the auricular cartilage anatomy. The described cartilage-sparing otoplasty procedure with the refinements outlined resulted in a reproducible natural correction, with a low risk profile, that can be applied to almost all prominent ears.
