Abstract
With the advent of widespread use of commercial ear molding products, the literature addressing the indications for and timing of perinatal intervention in auricular deformations and malformations has increased significantly. Although the rationale for perinatal ear molding seems to be hormonally mediated, the common assertion that breastfeeding may prolong the window of effective intervention remains without convincing evidence. The common auricular anomalies as well as indications, timing, and methodology of effective intervention including ear molding or surgical otoplasty are reviewed herein.

Nonsurgical Correction of Congenital Ear Deformities: The Relationship Between Age of Presentation and Regression. J Craniofac Surg 2022; 33:e822-e828. [PMID: 36102908 DOI: 10.1097/scs.0000000000008758] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Accepted: 04/02/2022] [Indexed: 11/26/2022] Open
Abstract
PURPOSE After 3 weeks of age, studies show ear molding to be unsuccessful due to increased regression rates. Studies have not differentiated success rates based on regression severity; partial regressions may be deemed successful and satisfactory by parents. We examined successful ear molding at different ages of presentation by measuring regression severity and parental satisfaction. METHODS Patients who presented to [blinded for review] for ear molding from January 2017 to October 2018 were eligible for inclusion. Molds were applied on the initial visit and monitored biweekly. Treatment length was based on age, deformity type, and severity. One month after treatment completion, parents completed a satisfaction survey where they assessed regression on a 3-point severity scale. RESULTS A total of 165 patients were included in this study. Sixty-seven were younger than 3 weeks of age and had an overall correction rate of 95%. The complete correction rate was 80% and only 5% saw complete regression. In the remaining 98, the overall correction rate was 94%, with a 63% complete correction rate. Only 6% saw complete regression. There was no statistical significance in parental satisfaction, perceived improvement, or likelihood to recommend ear molding between age groups. CONCLUSIONS Regression rates are higher in children older than 3 weeks although not statistically significant. Most regressions were partial and ear molding still significantly corrected most deformities. We suggest that ear molding be offered past 3 weeks of age, with maximum age being dependent on deformity type, as it still leads to high parental satisfaction.

Black JS, Duong RT, Samuel AR, Hui E, Cottler PS. Local estrogen for nonsurgical recontouring of auricular cartilage. J Plast Reconstr Aesthet Surg 2022; 75:2302-2309. [PMID: 35288037 DOI: 10.1016/j.bjps.2022.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 11/22/2021] [Accepted: 02/13/2022] [Indexed: 11/15/2022]
Abstract
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.

Abstract
BACKGROUND Neonatal ear is more malleable and soft, allowing the correction of deformities by using external molding. This is mainly attributed to high concentration of the proteoglycan aggregate and hyaluronic acid. In this study, HA dermal filler was injected in rabbit ear as a long acting HA source to investigate the biological impact of HA in reshaping the ear cartilage. MATERIALS AND METHODS Ears of twelve rabbits were divided into 4 groups. Control group was the left ears of 6 animals which were left intact. Group 2 was the right ears of the same animals, which received saline solution injection. Group 3 was the left ears of the other 6 animals, which were given 1 mL of HA. Group 4 was the right ears of them, which were given 2 mL of HA in both sites of the ear. All ears were folded and splinted for 4 weeks. Then, the angle of each ear was calculated. Following an additional 4 weeks, a cartilage biopsy was taken for histological examination. RESULTS The ear angles did not show any statistical difference at week 4. There was a significant difference among the groups at the 8th week. In the 3rd and 4th groups, mean angles were higher than the group 1 and group 2. Thickening in the cartilage and ectopic cartilage formation was observed in the contact areas to hyaluronic acid. Significant difference was also found between the peak and mean cartilage thicknesses. CONCLUSION HA dermal filler can stimulate cartilage regeneration by increasing the synthesis of extracellular matrix and chondrogenesis especially where it is in direct contact with the ear cartilage.

Abstract
OBJECTIVE Our research was carried out to provide a clinical reference for the application of nonsurgical therapy in newborns with congenital auricular deformities in east China. METHODS A retrospective study of consecutive newborns using noninvasive ear molding was conducted in Hangzhou in east China's Zhejiang Province. The demographic and clinical information and photographs of the ear before and after treatment were taken. The diagnosis of each auricular deformity was identified, and the treatment outcome was evaluated. RESULTS A total of 224 patients including 356 congenital ear anomalies received noninvasive ear molding. The median age of infants to initiate treatment was 39.5 days. The median treatment duration was 42.5 days. The median follow-up time was 137.0 days. The overall treatment effective rate of all infants with nonoperative ear molding was 92.1%, and mild skin irritation and ulceration occurred in 34 ear deformities (9.6%). It confirmed that the treatment efficiency was satisfactory and the complication rate was still acceptable despite the late initiation treatment of neonates in east China. Further analysis of treatment outcomes among three subgroups of infants (the ages to initiate the ear molding were respectively less than or equal to 28, 29-56, and more than 57 days) revealed that initiation treatment was significantly related to the treatment results and the earlier the initiation treatment, the higher the effective rate and the lower the complication incidence. CONCLUSION Our study hints that newborns in east China may have a longer period for correction. What is more, although our study affirmed a longer period for noninvasive molding, early diagnosis and treatment are still recommended to improve therapy efficiency and reduce treatment duration and complications.

Non-surgical Correction of Congenital Ear Anomalies: A Review of the Literature. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2020; 8:e3250.

Abstract
Congenital ear anomalies have been known to cause lasting psychosocial consequences for children. Congenital ear anomalies can generally be divided into malformations (chondro-cutaneous defect) and deformations (misshaped pinna). Operative techniques are the standard for correction at a minimal age of 5–7, exposing the children to teasing and heavy complications. Ear molding is a non-operative technique to treat ear anomalies at a younger age. Having been popularized since the 1980s, its use has increased over the past decades. However, uncertainties about its properties remain. Therefore, this review was conducted to look at what is known and what has been newly discovered in the last decade, comparing different treatment methods and materials. A literature search was performed on PubMed, and 16 articles, published in the last decade, were included. It was found that treatment initiated at an early age showed higher satisfactory outcome rates and a shorter duration of treatment. A shorter duration of treatment also led to higher satisfactory rates, which might be attributable to age at initiation, individual moldability, and treatment compliance. Complications were minor in all articles. Recurrence rate was low and mostly concerned prominent ears, which proved to be the most difficult to correct deformity as well. Malformations, however, were even more difficult to treat than deformations. Our analysis shows ear molding to be a successful treatment method for ear anomalies with a preference for early diagnosis and treatment.

Quality of life and nasal splints after primary cleft lip and nose repair: Prospective assessment of information and tolerance. J Craniomaxillofac Surg 2018; 46:1783-1789.

Abstract
Splints are commonly used after primary cleft surgery in order to secure the position of the nasal cartilages. Although the importance of splints is more and more stressed in the literature, many questions remain unanswered relative to the psychological impact of this device on children and families. Two questionnaires, Information and Tolerance, were used in order to measure the quality of life (QoL) associated with the use of nasal splints after primary cleft surgery. Information assessed the understanding of the parents the day before the procedure. Tolerance assessed their experience 3 months after splint placement. We prospectively included 41 consecutive patients from a Paris cleft center, 21 consecutive patients from a Russian center (Moscow) and 10 consecutive patients form a another French center (Nantes). In Paris and Nantes, an initial fixed splint was placed during the procedure until day 10, and then replaced by a removable splint for a period of 4 months. In the Moscow group, removable splints were used primarily for a total period of 4 months. Three types of removable splints were considered: commercial anatomical self-retentive splints (Nose-Fit™, Moscow, Russian Federation), in-house anatomical self-retentive splints and commercial Talmant-type splints requiring taping (Sebbin, Boissy-l'Aillerie, France). The data was analyzed as Likert scales and internal consistency was assessed using the Cronbach coefficient. Age at surgery, uni- or bilateral cleft, type of splint, number of splint changes and complications were tested against the scores of the questionnaires using multivariate models. We did not find correlations between the factors assessed by the multivariate analysis and the splint type. Information and Tolerance scores were high and showed satisfactory QoL associated with the use of splints. The internal consistency of the combination of the two forms was good. While the effects of splints on nasal morphology still need to be confirmed based on a controlled prospective study, we show here that this device is well tolerated by families and is not associated with specific complications.
