Nonsurgical treatment of various auricular deformities

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.

Spontaneous Resolution of Ear Lidding in Newborns: A Prospective Observational Cohort Study

ABSTRACT

Ear lidding is a cosmetic outer ear shape deformity commonly observed in newborns. Although lidding is considered a benign condition, psychological concerns such as bullying and depression have been observed in older children supporting correction of the condition. Nonsurgical correction of lidding using molding and splinting techniques has become increasingly popular, achieving successful outcomes in the majority of cases. Spontaneous resolution of the condition has also been reported in the literature however there is minimal prospective data available on the natural progression of ear lidding. In our case series of 11 closely followed newborns, we aimed to characterize the natural progression and resolution of lidding. Ten consecutive newborns participated in the observation plan and all 10 had complete spontaneous resolution of lidding within an average of 40 days. One other newborn's parents self-selected to have molding and splinting treatment. These results suggest that cosmetic treatment for less severe cases of ear lidding may be unnecessary as they have the potential to resolve on their own. Future research in this area could include controlled study designs and more work is needed to identify, which infants will require treatment. Our study may provide helpful reassurance to families and physicians that many newborns may see complete resolution of lidding without intervention.

Non-surgical Correction of Congenital Ear Anomalies: A Review of the Literature

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.

Newborn Ear Deformities: Early Recognition and Novel Nonoperative Techniques

Congenital auricular anomalies are common sources of aesthetic concern and psychosocial distress for both children and their parents. Only one-third of these anomalies self-correct, leaving a large need for acceptable corrective methods. Otoplasty is often the standard treatment; however, newer nonsurgical methods, including splinting and molding in the neonatal period, have shown favorable results without the complications of surgical intervention and with the advantage of early intervention. These treatment options have not yet been widely adopted in Western countries due to delayed diagnosis of auricular deformities and confusion regarding treatment indications and technique.

A prospective study on non-surgical correction of protruding ears: the importance of early treatment

OBJECTIVES

Splinting is an elegant method to correct ear deformities in the newborn. However evidence is lacking on the relation between age and efficacy and duration of the treatment. We prospectively studied these questions on protruding ears in 132 babies.

METHODS

A splint in the scaphal hollow was used in combination with tape (Earbuddies(®)). Treatment continued until the desired shape persisted. Results were judged from photographs and mastoid-helical distance was measured.

RESULTS

In 132 babies 209 ears were treated. Twenty-four patients had no follow-up, 27 stopped therapy for skin irritation and fixation problems. In the remaining patients results were good in 28%, fair in 36%, poor in 36%. Efficacy deteriorates with age; with fair or good results in 66.7% if therapy started before the sixth week. Older children needed to be splinted longer. The anti-helical fold was easier corrected than a deep concha (correction in 69.8% versus 26.8%).

CONCLUSIONS

Considering splinting therapy for protruding ears, a reasonable chance of success can only be offered to parents of children up to six weeks of age. It is favorable if the deformity is mainly due to a flat antihelix.

[Neonatal molding for minor deformities of auricular cartilage: a simple method]

Non-surgical correction of minor ear deformities by external splinting during neonatal age is a well-known, effective technique, but not frequently used in France. We would like to popularize an established, simple method that uses cheap, available means (a wire, adhesive strips and a silicone probe). It can be performed by parents, paediatricians and nurses. Spreading this method would allow early onset of treatment and better clinical results. On the long run, it would have a certain economic aftermath on national health insurance by reducing the number of surgical procedures for deformed ears.

Nonsurgical correction of congenital ear abnormalities in the newborn: Case series

OBJECTIVE

To determine whether a simple, nonsurgical treatment for congenital ear abnormalities (lop-ear, Stahl's ear, protruding ear, cryptotia) improved the appearance of ear abnormalities in newborns at six weeks of age.

METHODS

This is a descriptive case series. All newborns with identified abnormalities were referred by their family physician to one paediatrician (WGS) in a small level 2 perinatal centre. The ears were waxed and taped in a standard manner within 10 days of birth. Pictures were taken before taping and at the end of taping (one month). All patients and pictures were assessed by one plastic surgeon (JWT) at six weeks of age and scored using a standard scoring system. A telephone survey of the nontreatment group was conducted.

RESULTS

The total number of ears assessed was 90. Of this total, 69 ears were taped and fully evaluated in the study (77%). The refusal rate was 23%. In the treatment group, 59% had lop-ear, 19% had Stahl's ear, 17% had protruding ear and 3% had cryptotia. Overall correction (excellent/improved) for the treatment group was 90% (100% for lop-ear, 100% for Stahl's ear, 67% for protruding ear and 0% for cryptotia). In the nontreatment (refusal) group, 67% of the ears failed to correct spontaneously. No complications were recognized by the authors or parents by six weeks. The percentage of newborns in one year in the perinatal centre with recognized ear abnormalities was 6% (90 of 1600).

CONCLUSIONS

A simple, nonsurgical treatment in a Caucasian population appeared to be very effective in correcting congenital ear abnormalities with no complications and high patient/parent satisfaction.
