Near-Total Ear Avulsion Repaired With Primary Closure and Hyperbaric Oxygen: A Case Series and Review of the Literature.

INTRODUCTION: Near-total ear avulsion is a rare and challenging problem to repair with many techniques described; primary repair is an attractive option but is not always successful. Healing may be augmented with postoperative hyperbaric oxygen therapy (HBOT), but this technique is under-reported, and an ideal regimen is not known. The study objective is to discuss the role of HBOT in the management of ear avulsion by reviewing 2 unique cases. METHODS: Case report and review of the literature. A Pubmed search using the terms ear avulsion and postoperative hyperbaric oxygen was performed. RESULTS: Two pediatric patients presented with near-total avulsion of the auricle after suffering a dog bite. Various management options were discussed including observation, primary repair, post-auricular cartilage banking, graft reconstruction with periauricular tissue or rib cartilage, or microsurgical replantation. The decision was made to perform primary reattachment, followed by adjuvant hyperbaric oxygen therapy (HBOT). The patients achieved favorable esthetic results and continue to maintain the function of the reattached ear. Photo documentation was obtained throughout the process. DISCUSSION: There is no consensus on the management of near-total ear avulsion. Primary repair is ideal from a cosmetic and ease-of-operation standpoint but does not always yield viable tissue. The use of postoperative HBOT is an attractive option that may boost success rates, but the ideal HBOT regimen is unknown. These cases represent a successful application of this innovative technique in a pediatric patient.

A 10-Year Retrospective Review of the Nonsurgical Treatment of Infant Ear Anomalies.

BACKGROUND: A review of a single surgeon's 10-year experience treating congenital ear anomalies using nonsurgical ear molding is presented. This study assesses the efficacy of treating a variety of anomalies in infants with age ranging from younger than 1 week to 22 weeks and identifies potential barriers to care. METHODS: A retrospective chart and photographic review of 246 consecutive infants treated with ear molding between 2010 and 2019 was undertaken. Data regarding patient demographics, anomaly classification, device selection, treatment duration, adverse events, and satisfaction with outcomes were collected. RESULTS: This study included 385 infant ear anomalies in 246 patients. Median age at initiation of treatment was 16 days and median treatment duration was 29.5 days. A median number of three devices was needed to complete bilateral treatment. Treated anomalies included mixed deformity, helical rim, prominent, lidding/lop, Stahl ear, conchal crus, cupping, and cryptotia. Complications occurred in 47 patients, with skin breakdown being the most common [26 patients (55.3 percent)]. Satisfaction rate was 92 percent in 137 surveyed parents. Median patient household income was approximately $112,911, and treatment was covered by insurance for 244 of 246 patients. CONCLUSIONS: The study outcomes demonstrate that ear molding can be effective in patients as old as 22 weeks without compromising treatment duration or complexity. In addition, in the authors' experience, molding is an effective treatment for the majority of infant ear deformities. Despite a steady increase in patient volume over the past 10 years and consistent coverage of treatment by insurance, the authors' catchment area continues to be largely limited to affluent households. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Evolution of Anomaly-Specific Techniques in Infant Ear Molding: A 10-Year Retrospective Study.

BACKGROUND: Congenital ear anomalies occur in at least one-third of the population, and less than one-third of cases self-correct. Ear molding is an alternative to surgery that spares operative morbidity and allows for significantly earlier intervention. In this retrospective study, the senior author (S.B.B.) developed a tailored approach to each specific type of ear deformity. The use of modifications to adapt standard ear molding techniques for each unique ear are described. METHODS: The authors conducted a retrospective, institutional review board-approved study of 246 patients who underwent ear molding performed by a single surgeon. The procedure reports for each case were reviewed to develop stepwise customization protocols for existing EarWell and InfantEar systems. RESULTS: This review included 385 ears in 246 patients. Patient age at presentation ranged from less than 1 week to 22 weeks. Presenting ear deformities were subclassified into mixed (37.4 percent), helical rim (28.5 percent), prominent (10.6 percent), lidding/lop (9.3 percent), Stahl ear (3.6 percent), conchal crus (3.3 percent), and cupping (2.8 percent). Two patients (0.8 percent) had cryptotia. Deformity subclass could not be obtained for 11 patients (4.5 percent). Recommended modifications to existing ear correction systems are deformity-specific: cotton-tip applicator/setting material (Stahl ear), custom dental compound mold (lidding/lop and cupping), scaphal wire (helical rim), cotton-tip applicator/protrusion excision (prominent), and custom dental compound stent (conchal crus). CONCLUSIONS: Presentation of ear anomalies is heterogenous. This 10-year experience demonstrates that the approach to ear molding should be dynamic and customized, using techniques beyond those listed in system manuals to complement each ear and to improve outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Lop Ear to Conchal Microtia: An Algorithmic Surgical Approach.

BACKGROUND: The lop ear deformity is defined by a deficient helix and scapha, underdeveloped anthelix, and downfolding of the helix. The terminology used is still confusing, and the treatment is not entirely structured. The aim of this study was to provide a new systematic surgical approach of this deformity based on our center's experience. MATERIALS AND METHODS: All patients undergoing surgical correction of lop ears between 2007 and 2019 at Great Ormond Street Hospital were included. Patients' data, surgical techniques, and postoperative complications were recorded. RESULTS: Based on our records, we identified 3 surgical techniques for the correction of lop ears, based on the degree of deformity encountered. In a mild lop ear, correction was achieved with a modified otoplasty technique by improving the definition of the antihelix and superior crus. In a moderate deformity, additional remodeling of the lidded helix was performed (extended otoplasty), whereas for the severe lop ear, the amount of cupping and the deficient cartilage required formal reconstruction using a carved rib cartilage framework. There were a total of 109 patients and 146 lop ears: 58 mild, 27 moderate, and 61 severe lop ears. CONCLUSION: We feel that there is a point in the spectrum of congenital ear deformity when a severe lop ear becomes a conchal microtia and recommend this approach to simplify the management of these cases. This is intended to bring greater clarity to how to deal with lop ears, based on the severity of the deformity and the surgical techniques used.

Arterial only anastomosis associated with modified Baudet technique in ear replantation: Case reports and literature review.

BACKGROUND: Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice. We propose the association of microsurgical techniques with some modification (modified Baudet technique) to obtain higher survival rate of the reimplanted stump. METHODS: This study included cases of 3 male patients with total ear amputation, the injuries and their mechanism (workplace accident) being identical. Chief complaints were pain, bleeding, important emotional impact due by an unaesthetic appearance. The established diagnosis was traumatic complete ear amputation (grade IV auricular injury according to Weerda classification). Microsurgical replantation was performed only with arteriorraphy, and no vein anastomosis. Cartilage incisions and skin excisions were made to enlarge the cartilage-recipient site contact area. Medicinal leeches were used to treat venous congestion, to which systemic anticoagulant therapy was added. RESULTS: The results showed the survival of the entire replanted segment in all cases, with good function and esthetical appearance. Patients were fully satisfied with the final outcome. CONCLUSION: Microsurgical replantation is the gold standard, for the surgical treatment of total ear amputation. We believe that cartilage incisions and the increased surface of contact between cartilage and recipient site has an adjuvant role in revascularization of the amputated stump (with only arterial anastomosis) and the use of hirudotherapy helps to relieve early venous congestion.

Outpatient Posttraumatic Auricle Reconstruction Under Local Anesthesia.

ABSTRACT: We described an outpatient auricle reconstruction in an elderly patient after an accidental facial trauma. The procedure was carried out under local anesthesia given patient's comorbidities and acetylsalicylic acid (ASA) therapy. The patient subsequently underwent to regular follow-up. An excellent healing of the auricle injury was achieved.

Anesthetic and Analgesic Efficient of Regional Nerve Blockade in Otoplasty.

AIM: The prominent ear is the most common congenital deformity of the external ear. Otoplasty is performed to correct the appearance of the prominent ear. This study was planned to compare the analgesic and anesthetic effects of local nerve blockade and local infiltration anesthesia in the otoplasties. METHOD: Thirty-two patients who underwent otoplasty in both ears between February 2018 and March 2019 were included in the study. Three patients were excluded because they refused regional anesthesia. In the patients included in the study, only local infiltration anesthesia was applied to 1 ear and regional nerve blockade was applied to the other ear. Regional nerve blockade was applied to the study group; local infiltration anesthesia was applied to the control group. Surgical and anesthetic complications were recorded. The onset time, duration and severity of pain were followed. Numerical evaluation scale scores were used to evaluate pain levels. RESULTS: It was observed that the first pain of the patients On the side where regional nerve block (RNB) anesthesia was applied after an average of 10.5 hours. On the other hand on the side where local infiltration anesthesia was applied; the pain was observed to start after an average of 3.5 hours. At the 6th and 12th hours postoperatively, the scores of the numerical evaluation scale were significantly lower in the study group than the control group (P < 0.05). At the 24th-hour pain score, the values were lower in the study group, but the difference was not significant between the groups (P > 0.05). In the regional anesthesia group, can develop such as difficulty in swallowing, weakness in the neck, weakness in the upper extremity, nausea, Horner syndrome; but all side effects resolve spontaneously within 6 to 12 hours. CONCLUSION: The application of regional anesthesia in prominent ear surgical procedures can be considered as an alternative method to provide better quality preoperative anesthesia and better quality postoperative analgesia in patients.

Using an expanded scalp flap without fascial flap harvest or skin grafting for total auricular reconstruction in hemifacial microsomia with low hairline.

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

Topical vapocoolant spray reduces nociceptive response to ear notching in neonatal piglets.

OBJECTIVE: To evaluate the efficacy of a vapocoolant spray (VS) to provide local anaesthesia for piglets during ear notching. STUDY DESIGN: Randomized study. ANIMALS: Eleven 10 day old and forty 3-5 day old Large White piglets. METHODS: Temperature validation studies using thermocouples and a temperature data logger were conducted on dead and live tissue to determine optimal spray distance and duration to reduce tissue temperature to below 10 °C. A behavioural trial was conducted to assess efficacy for ear notching. Piglets were randomly assigned to one of four treatment groups: positive control (POS; n = 10), VS (n = 10), lignocaine (LIG; n = 10) and negative control (NEG; n = 10). Spray was administered to the margin of each ear, from a distance of 10 cm, and for a duration of 2 seconds immediately prior to ear notching. Behavioural observation was used to assess movement and vocal response, with responses categorized as no response (0) and response (1). RESULTS: Temperature and tissue validation studies indicated that a 2 second spray from 10 cm reduced tissue temperature to below 10 °C, and reduced response to stimulation of the skin with an 18 gauge needle (p < 0.001). There was a significant effect of treatment on response to ear notching (p < 0.001). The probability of a piglet to respond to ear notching was 98.7% for NEG piglets, compared with those treated with VS (5.3%), LIG (1.1%) and sham-notched piglets (0.9%). CONCLUSIONS AND CLINICAL RELEVANCE: This study contributes new data on the pain of ear notching in piglets. The application of a topical VS prior to ear notching reduced the antinociceptive response of piglets to the procedure, similar to that of a local anaesthetic. Cryoanaesthesia presents a simple and effective option for reducing the pain response to this simple husbandry procedure.

Early postoperative magnet application combined with hydrocolloid dressing for the treatment of earlobe keloids.

BACKGROUND: To prevent the recurrence of earlobe keloids after surgical removal, a reliable and safe postoperative treatment method is critical. To the authors' knowledge, no studies have elucidated the most effective postoperative dressing method for preventing the recurrence of earlobe keloids. This study aimed to compare keloid recurrence rates in patients whose keloids were dressed using conventional methods (plain gauze or a polyvinyl alcohol sponge) with those of a matched cohort of patients whose keloids were dressed using magnets combined with hydrocolloid materials. METHODS: This observational case-control study compared a retrospective cohort of patients whose keloids were dressed using conventional methods with a matched prospective cohort of patients whose keloids were dressed using magnets combined with hydrocolloid materials. The study included patients with pathologically confirmed earlobe keloids that were surgically excised with primary closure. Patients 8 years of age or older underwent adjuvant pressure therapy with magnets at the study hospital. Patients were excluded from the study if they were unavailable for follow-up evaluation, if they had received additional adjuvant therapy during treatment, or if histologic confirmation of a keloid was not obtained. Matched-pair analysis was performed using the McNemar test. Treatment outcome was evaluated as recurrence or nonrecurrence. RESULTS: Overall, 9 (11.2%) of the 80 study patients experienced recurrence. The recurrence rate was significantly lower in the matched case group (2 of 40, 5%) than in the matched control group (7 of 40, 17.5%) during the follow-up period of 18 months (p=0.0253). CONCLUSIONS: The authors' novel dressing of magnets and hydrocolloid materials appears to be effective in reducing earlobe keloid recurrence.

Comparação entre otoplastia realizada com anestesia local com sedação e sem / Comparison between otoplasty performed under local anesthesia with and without sedation

Ear flappy is a congenital deformity most common of external ear, is transmitted by dominant form and occurs in 5% of general population. There are three main ways to do the modern surgery: the shaving, exision and fixation for stitchs of ear gristle. The technique of Mestardé, in 1963, do a new antihelice was supported in permanent sutures for posterior way and the stitchs takes until anterior perichondrium, without takes the skin. Furnas (1968) done suture with unabsorbed thread in conchal gristle, transfixing until anterior perichondrium and sutures in mastoid fascia. The otoplasty can be done with local anesthesia associated or not with sedation or with general anesthesia. The aim of the study is to evaluate the intensity of pain of patients submited to otoplasty with local anesthesia with sedation and without sedation, comparing two techniques. Method: There was separated 2 groups: Group 1: 12 patients operates with local anesthesia and sedation in surgery center; group 2: 26 patients operated with local surgery in clinic of small surgeries. The study was done in one year (2011 to 2012 May). It was done a lot of questions with these patients to evaluate the level of pain during the surgery and post-surgery. Results: There was not significant diference between two groups. Conclusion: It is possible to do this surgery with less hospital cost and the use the rooms in surgery center for more complex surgeries...

Orelha em abano representa a deformidade congênita mais comum da orelha externa, é transmitida de forma autossômica dominante e afeta aproximadamente 5% da população em geral. Existem três vias principais para a realização da otoplastia moderna: a raspagem, excisão e fixação por pontos da cartilagem auricular. A abordagem de Mustardé, em 1963, para a criação de uma novo anti-hélice era baseado em suturas permanentes por acesso posterior e os pontos englobavam até o pericôndrio anterior, sem transfixar a pele. Furnas (1968) realizava sutura com fio inabsorvível posicionado na cartilagem conchal transfixando até pericôndrio anterior e suturado na fáscia mastoide. A otoplastia pode ser realizada com anestesia local associada ou não à sedação ou com anestesia geral. Objetivo: O presente estudo tem como objetivo avaliar a intensidade da dor dos pacientes submetidos à otoplastia sob anestesia local com sedação e sem sedação, comparando as duas técnicas anestésicas. Método: Foram separados dois grupos: Grupo 1 - 12 pacientes operados com anestesia local e sedação no centro cirúrgico; Grupo 2 - 26 pacientes operados com anestesia local e sem sedação no ambulatório de pequenas cirurgias. O estudo foi realizado no período de 1 ano (maio de 2011 a maio de 2012). Foi realizado um questionário com esses pacientes para avaliarmos o nível de dor no intraoperatório e pós-operatório. Resultados: Não houve diferença estatisticamente significativa entre os dois grupos. Conclusão: É possível realizarmos essa cirurgia com menor custo hospitalar e utilizarmos as salas do centro cirúrgico com anestesista para cirurgias mais complexas...

Otoplastia: resultados del abordaje anterior frente al posterior / Otoplasty: results after anterior versus posterior approach

Introducción y objetivo: En la otoplastia, el abordaje anterior combinado con suturas se utiliza cada día más, dado que es una técnica muy poco agresiva con el cartílago. El objetivo de este estudio es comprobar la utilidad del abordaje anterior, comparándola con el abordaje retroauricular. Material y métodos: Estudio retrospectivo sobre 25 otoplastias intervenidas en el periodo 2004-2008. Se revisa la historia de 13 pacientes (25 otoplastias), con un rango de edad de 7 a 41 años. En el abordaje anterior, el cartílago auricular se adelgaza mediante limado y se modela el pliegue del antehélix mediante suturas. Resultados: De las 25 otoplastias, el 92% fueron bilaterales, con un 54% de niños y un 46% adultos; la anestesia fue local en 20% y general en 80%. El abordaje fue anterior en el 44% y retroauricular en el 56%. Respecto a las complicaciones, en el abordaje anterior hubo extrusiones de puntos en 82%, reacción a cuerpo extraño en 9%, y fue necesaria una cirugía de revisión en el 28% de las 11 otoplastias operadas. En el abordaje posterior, hubo extrusiones de puntos en 21%, reacción a cuerpo extraño en 7%, ulceración de la piel en 7%, siendo necesaria la cirugía de revisión en 7% de las 14 orejas intervenidas. Globalmente, el 85% de los pacientes están satisfechos con el resultado estético de la cirugía. La extrusión de puntos fue estadísticamente más frecuente tras abordaje anterior. Conclusiones: La otoplastia permite obtener buenos resultados estéticos para el tratamiento de las orejas en asa. La complicación más común es la extrusión de puntos de sutura, siendo más frecuente cuando el abordaje es anterior (AU)

Introduction and objective: In otoplasty, an anterior approach with sutures is commonly used, because it is not aggressive with cartilage. The aim of this study on otoplasty was to evaluate the usefulness of the anterior approach, comparing it to the results obtained after the posterior approach. Material and methods: Retrospective study on 25 otoplasties performed at a University Hospital during the period 2004-2008. Clinical records from 13 patients (25 otoplasties), between 7-41 years of age, were reviewed. In the anterior approach, the anterior surface of the auricular cartilage is scratched with a rasp. The antihelix shape is obtained and mattress sutures are placed through the anterior surface of the ear. Results: Out of 25 otoplasties, 92% were bilateral and 8%, unilateral; 54% of the patients were children and 46%, adults; anaesthesia was local in 20% and general in 80%. We performed 11 anterior and 14 posterior approach otoplasties. After an anterior approach, complications were suture extrusion in 82%, foreign body reaction in 9%, and revision surgery was needed in 28% of 11 otoplasties performed. After a posterior approach, complications were suture extrusion in 21%, foreign body reaction in 7%, and revision surgery was needed in 7% of 14 otoplasties performed. A good aesthetic result was obtained in almost all the cases (85%). Extrusion rate was statistically more common after the anterior approach. Conclusions: In our opinion, otoplasty is a simple technique for treatment of prominent ears, with good aesthetic results. The most common complication is suture extrusion, more frequent after an anterior approach (AU)

Minimally invasive ear reshaping with a 1450-nm diode laser using cryogen spray cooling in New Zealand white rabbits.

BACKGROUND: Otoplasty is the current standard of care for treating prominent ears, a psychologically and sometimes functionally disabling disorder. The technically demanding procedure carries many risks such as poor aesthetic outcome, need for revision surgery, and need for general anesthesia. This study investigates the use of laser irradiation combined with cryogen skin cooling and stenting to reshape cartilage in the ears of New Zealand white rabbits. METHODS: In this prospective, randomized, internally controlled animal study, the right ears of 9 rabbits were mechanically deformed with a jig and then irradiated with a 1450-nm diode laser combined with cryogen skin cooling (14 J/pulse with cryogen spray for 33 milliseconds per cycle and a 6-mm spot size). The left ear served as the control. The ears were splinted for 1, 3, or 4 weeks. The rabbits were then given a lethal dose of intravenous pentobarbital, and the splints were removed and ears examined and photographed. Light and confocal microscopy were performed on the specimens. RESULTS: Shape change was observed in all 9 treated rabbit ears, while none of the control ears (stenting alone) showed significant change. Qualitatively, reshaped ears were stiffer after 4 weeks of splinting than after 1 or 3 weeks. None of the rabbits showed evidence of skin injury nor did they show signs of postprocedural pain. Findings from histologic analysis in the treated areas showed evidence of an expanded chondrocyte population in the region of laser irradiation, along with some perichondrial thickening and some fibrosis of the deep dermis. Confocal microscopy revealed minimal cellular death at 1 week and none thereafter. CONCLUSIONS: Cartilage reshaping using laser energy can be performed safely transcutaneously using cryogen spray cooling in rabbits. This animal model has similarity to human ears with regard to skin and cartilage thickness and is a stepping stone toward developing minimally invasive laser auricle reshaping in humans.

Z-plasty for Tanzer type IIb constricted ears.

This article describes the Z-plasty technique for Tanzer type IIb constricted ears. The technique was used in 6 patients to lengthen the upper pole of the ear with simultaneous unfurling of the cupping deformity. All patients also underwent creation of an antihelix with Mustarde sutures as well as a "mastoid hitch" (sutures between the upper pole of the ear and the mastoid fascia) to prevent recurrence. After a mean follow-up of 1.5 years, all patients were satisfied with no recurrence of the deformity. The advantages and disadvantages of the Z-plasty are discussed and compared with other techniques.

Osteoradionecrosis of tympanic bone: reconstruction of outer ear canal with pedicled skin flap, combined with hyperbaric oxygen therapy, in five patients.

OBJECTIVE: To evaluate the results of one-stage surgical repair of the meatal skin defect in patients with long-lasting osteoradionecrosis of the outer ear canal, using a postauricular, inferiorly pedicled skin flap. All patients were also treated with hyperbaric oxygen both pre- and post-operatively. METHODS: A prospective study evaluating the results of a one-stage surgical procedure to repair the meatal skin defect in five patients with osteoradionecrosis of the outer ear canal. All patients were treated with hyperbaric oxygen both pre- and post-operatively. RESULTS: In four of the five patients, intact canal skin was achieved after surgery and hyperbaric oxygen therapy. One patient needed a second operation to cover a small remaining area of bare bone. In one patient, wound healing was unsatisfactory and an area of bare bone remained. CONCLUSION: In cases of osteoradionecrosis of the outer ear canal, the skin defect can be repaired with an inferiorly pedicled skin flap. Although not yet scientifically proven, the peri-operative application of hyperbaric oxygen may be of additional value to improve wound healing in areas of compromised tissue.
