Porous Polyethylene Versus Autologous Costochondral Reconstruction for Microtia: Incidence and Analysis of Secondary Procedures.

OBJECTIVE: To examine the frequency of autologous and alloplastic ear reconstructions for patients with microtia in the United States, and describe post-index procedure rates associated with each method. DESIGN: Retrospective cohort study. SETTING: Claims data from 500 + hospitals from IBM® MarketScan® Commercial and Multi-State Medicaid databases. PATIENTS/PARTICIPANTS: A total of 649 patients aged 1 to 17 years with International Classification of Diseases, ninth/tenth revision (ICD-9/10) diagnoses for microtia, congenital absence of the ear, or hemifacial microsomia. INTERVENTIONS: Alloplastic or autologous ear reconstruction between 2006 and 2018. MAIN OUTCOME MEASURE: Post-index procedures performed within 1 year following the index repair, analyzed across the study period and separately for each half of the study period (2006-2012, 2012-2018). RESULTS: A total of 486 (75%) qualifying patients received autologous and 163 (25%) received alloplastic reconstruction. Secondary procedure rates were significantly higher in the autologous group at 90 days (P = .034), 180 days (P < .001), and at 365 days (P < .001). Alloplastic reconstruction accounted for 23.2% of reconstructions in the first half of the study period compared with 26.7% in the second half (P = .319). One-year secondary procedure rates in the autologous group were not significantly different between both halves of the study period (69.7% vs 67.1%, P = .558), but were significantly lower in the second half for the alloplastic group (44.9% vs 20.2%, P = .001). CONCLUSIONS: In these databases, autologous reconstruction is more common than alloplastic reconstruction. Autologous reconstruction is staged, with most undergoing a secondary procedure between 3 months and 1 year postoperatively. Secondary procedure rates decreased over time in patients undergoing alloplastic reconstruction.

Secondary Salvage of the Unsatisfactory Microtia Reconstruction.

BACKGROUND: Because auricular reconstruction is a complex and relatively uncommon procedure, there are many patients that have had disappointing reconstructions. This study describes the authors' large experience with secondary procedures in patients with unsatisfactory or failed initial ear reconstruction. METHODS: A prospectively maintained database of all consecutive patients who underwent secondary total ear reconstruction from March of 1991 to December of 2017 was reviewed. Demographic data and outcomes were assessed. Patients with acquired absence of the ear were not included. RESULTS: There were 144 microtia patients that met the inclusion criteria. Patient age at the time of the secondary reconstruction ranged from 3 to 59 years. Follow-up duration ranged from 1 to 21 years. Primary reconstruction was performed with rib cartilage in 91 patients, porous polyethylene implant in 47 patients, prosthesis in four patients, and irradiated cadaver rib cartilage in two patients. All secondary reconstructions were performed with porous polyethylene implants. The alloplastic framework was covered with a temporoparietal fascia flap in 76 patients, an occipital fascia flap in 64 patients, and a free fascia flap in four patients (two radial forearm flaps in the same patient, one contralateral temporoparietal fascia flap, and one lateral arm flap). Fourteen patients (10 percent) had complications requiring revision surgery. Secondary surgery was successful in all but one patient. CONCLUSIONS: These data represent the largest series of secondary total ear reconstructions. The use of a porous polyethylene implant is an ideal method for these patients because of its minimal morbidity and relatively low complication rate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Cosmetically Challenging Congenital Melanocytic Nevi.

BACKGROUND: Congenital melanocytic nevi (CMN) have a 1% to 5% lifetime risk for malignant transformation, with 50% of transformations occurring before the age of 5 years.The aim of this study is to assess the risk of melanoma development in pediatric patients with facial CMN involving the eyebrows, eyelid margins, and nasal alae where a margin of CMN was not excised to preserve these structures. METHODS: A retrospective chart review of all pediatric patients with CMN from 1986 to 2014 was performed to review demographic information, diagnosis, and number of surgeries. Patients' clinical photographs were evaluated for residual nevi after completion of the treatment. RESULTS: More than 950 medical charts of patients with CMN of the face area were reviewed. We identified 32 patients (13; 41% male) that met the study criteria with pathology-confirmed diagnosis of facial CMN with an average age of 4.4 years (3.3 months-15.8 years) at the time of initial surgery. The CMNs were classified into small (1; 3%), medium (14; 44%), large (14; 44%), and giant (3; 9%) based on their projected adult sizes. No patients developed melanoma within the small residual lesions left over the eyebrows and eyelids and inside nostrils at an average follow-up time of 5.6 (1.0-14.4) years and average age of 9.6 (1.8-19.2) years at the time of last follow-up. CONCLUSIONS: Although a lifelong risk of malignant transformation of the residual CMN cannot be concluded, our results found no transformation in follow-up visits at an average age beyond the highest risk of melanoma development in childhood. We feel that leaving residual lesions on the face in areas of important anatomic structures for better cosmetic outcome is an acceptable risk.

Porous Polyethylene Ear Reconstruction.

The use of a porous polyethylene implant covered with a well-vascularized fascial flap allows ear reconstruction at an early age (before school) with minimal morbidity and psychological trauma. Excellent outcomes with minimal morbidity can be obtained using this technique. This type of microtia reconstruction provides a more holistic approach because it is done at a younger age, in a single stage, as an outpatient and could address the functional hearing issues earlier.

Soft Palate Dysfunction in Children With Microtia.

BACKGROUND: Speech issues in microtia patients have been historically attributed to poor hearing. However, the authors have noted that almost all patients with microtia have palatal dysfunction. The aim of this study is to determine the prevalence of soft palate dysfunction (SPD) and velopharyngeal insufficiency (VPI) in microtia patients. METHODS: A prospective cohort study was performed on consecutive microtia patients from March to June 2017. Clinical characteristics were collected. Palate movement was rated by oral examination and degree of nasal escape by the mirror-fogging test. Correlations between clinical characteristics of microtia and SPD were determined. RESULTS: Ninety-seven (40 unilateral, 27 bilateral, and 30 control) children met inclusion criteria. Among all 67 patients with microtia, 96% (64 patients) showed SPD. Twenty-four unilaterals (60%) and 23 bilaterals (85%) had observable VPI by mirror examination. Of these patients, nasality was noticeable to the examiners in 14 unilaterals (58%) and 21 bilaterals (91%). Sixteen of the 27 bilaterals (59%) showed almost no movement of the soft palate. There was a significant correlation between SPD and mirror-fogging. A less developed middle ear as determined by computed tomography scan was associated with palatal dysfunction (P = 0.007). The severity of mandibular shift (P = 0.048) and presence of a syndrome (P = 0.045) were associated with grade of VPI. The severity of the ear deformity (P = 0.007) and presence of a syndrome (P = 0.034) were also correlated with the presence of SPD. CONCLUSIONS: This is the first study that documents the presence of VPI due to soft palate dysfunction in patients with isolated and nonisolated microtia.

The Occipital Artery-Based Fascial Flap for Ear Reconstruction.

BACKGROUND: The temporoparietal fascia flap is frequently used in ear reconstruction. When the temporoparietal fascia flap is unavailable, options for primary or secondary salvage reconstruction are limited. In these patients, an inferiorly based occipital artery fascia transpositional flap is a good alternative for soft-tissue coverage over a framework. This article describes the use of the occipital artery fascia flap for ear reconstruction in conjunction with a porous polyethylene framework. METHODS: The authors included all patients who underwent occipital artery fascia flap surgery with a porous polyethylene framework for ear reconstruction performed by the first author from 1992 to 2017. RESULTS: A total of 83 patients received an occipital artery fascia flap: 24 for primary microtia reconstruction and 59 for revision or salvage of unsatisfactory results. All had contraindications for temporoparietal fascia flap use: prior use, flap injury from previous surgery, trauma, inappropriate flap location, or inadequate flap perfusion. Twelve patients (14 percent) developed occipital artery fascia flap complications (infection or necrosis) and underwent further revision to achieve satisfactory results. CONCLUSIONS: Given the paucity of reported techniques for large-scale auricular salvage/revision, the authors offer a versatile option that remains available when other conventional flaps are unavailable. The occipital artery fascia flap may be used with either alloplastic or autologous frameworks. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Polyethylene Ear Reconstruction: A State-of-the-Art Surgical Journey.

BACKGROUND: The use of a porous high-density polyethylene implant for ear reconstruction is gradually gaining acceptance because it allows for a pleasing ear reconstruction in young children before they enter school. In response to this growing interest, the authors decided to write an article clarifying in detail all the steps of this challenging procedure. In this article, the authors also answer all the common questions that surgeons have when they come to observe the operation, or when they go back to their respective practices and start performing this procedure. METHODS: The authors describe in detail the operative steps that allow for a successful ear reconstruction using porous high-density polyethylene. The key parts of this operation are to meticulously harvest a well-vascularized superficial temporoparietal fascia flap and to use appropriate color-matched skin grafts. RESULTS: This method allows for a pleasing ear reconstruction with excellent definition, projection, symmetry, and long-term viability. CONCLUSION: The use of porous high-density polyethylene with a thin superficial temporoparietal fascia flap coverage is the authors' preferred method of ear reconstruction because it can be performed at an earlier age, in a single stage, as an outpatient procedure, and with minimal discomfort and psychological trauma for the patients and parents.

Auricular Reconstruction Using Porous Polyethylene Implant Technique.

Alloplast-based ear reconstruction has become more popular over the years because it offers many advantages compared with the traditional staged autologous costal cartilage approach. Advantages include earlier reconstruction in the setting of microtia, fewer procedures, less donor site morbidity, shorter surgeon learning curve, and improved consistency in the final aesthetic result. Although other implantable materials have been used in auricular reconstruction with variable success, porous high-density polyethylene frameworks combined with recent advances in the creation of the soft tissue coverage have significantly improved outcomes with minimal complications and long-term viability. This article describes the authors' technique.

Getting a Valid Survey Response From 662 Plastic Surgeons in the 21st Century.

INTRODUCTION: Web-based surveys save time and money. As electronic questionnaires have increased in popularity, telephone and mailed surveys have declined. With any survey, a response rate of 75% or greater is critical for the validity of any study. We wanted to determine which survey method achieved the highest response among academic plastic surgeons. METHODS: All American Association of Plastic Surgeons members were surveyed regarding authorship issues. They were randomly assigned to receive the questionnaire through 1 of 4 methods: (A) emailed with a link to an online survey; (B) regular mail; (C) regular mail + $1 bill, and (D) regular mail + $5 bill. Two weeks after the initial mailing, the number of responses was collected, and nonresponders were contacted to remind them to participate. The study was closed after 10 weeks. Survey costs were calculated based on the actual cost of sending the initial survey, including stationary, printing, postage (groups B-D), labor, and cost of any financial incentives. Cost of reminders to nonresponders was calculated at $5 per reminder, giving a total survey cost. RESULTS: Of 662 surveys sent, 54 were returned because of incorrect address/email, retirement, or death. Four hundred seventeen of the remaining 608 surveys were returned and analyzed. The response rate was lowest in the online group and highest in those mailed with a monetary incentive. CONCLUSIONS: Despite the convenience and low initial cost of web-based surveys, this generated the lowest response. We obtained statistically significant response rates (79% and 84%) only by using postal mail with monetary incentives and reminders. The inclusion of a $1 bill represented the greatest value and cost-effective survey method, based on cost per response.

Ear Reconstruction in Young Children.

The use of a porous high-density polyethylene ear implant, rather than a costal cartilage framework, allows ear reconstruction in young children before they enter school. The fact that the growth of the normal ear matures early allows for good symmetry. If the implant is covered completely with a large, well-vascularized superficial parietal fascia flap and appropriately color-matched skin, an ear with excellent projection and definition can be obtained with minimal complications and long-term viability. Ear reconstruction in young children is preferred by the author because the necessary fascial flap coverage is thinner, easier to harvest than in older patients, and can be done in a single outpatient procedure with minimal discomfort or psychological trauma.

Missense mutation in the PTEN promoter of a patient with hemifacial hyperplasia.

The cellular mechanisms involved in the asymmetric facial overgrowth syndrome, hemifacial hyperplasia (HFH), are not well understood. This study was conducted to compare primary cell cultures from hyperplastic and normal HFH bone for cellular and molecular differences. Primary cultures developed from biopsies of a patient with isolated HFH showed a twofold difference in cell size and cell number between hyperplastic and normal bone. Microarray data suggested a 40% suppression of PTEN (phosphatase-tensin homolog) transcripts. Sequencing of the PTEN gene and promoter identified novel C/G missense mutation (position -1053) in the regulatory region of the PTEN promoter. Western blots of downstream pathway components showed an increase in PKBa/Akt1 phosphorylation and TOR (target of rapamcyin) signal. Sirolimus, an inhibitor of TOR, when added to overgrowth cells reversed the cell size, cell number and total protein differences between hyperplastic and normal cells. In cases of facial overgrowth, which involve PTEN/Akt/TOR dysregulation, sirolimus could be used for limiting cell overgrowth.

Auricular reconstruction for microtia: A review of available methods.

Several surgical techniques have been described for auricular reconstruction. Autologous reconstruction using costal cartilage is the most widely accepted technique of microtia repair. However, other techniques have certain indications and should be discussed with patients and families when planning for an auricular reconstruction. In the present review, the authors discuss the main surgical techniques for auricular reconstruction including autologous costal cartilage graft, Medpor (Stryker, USA) implant and prosthetic reconstruction. To further elaborate on the advantages and disadvantages of each technique, the authors invited leaders in this field, Dr Nagata, Dr Park, Dr Reinisch and Dr Wilkes, to comment on their own technique and provide examples of their methods.

Plusieurs techniques chirurgicales de reconstruction auriculaire ont déjà été décrites. La reconstruction autologue à l'aide de cartilage costal est la technique la plus acceptée pour la réparation des microties. Cependant, d'autres techniques sont parfois indiquées et devraient être proposées aux patients et à leur famille au moment de planifier une reconstruction auriculaire. Dans la présente analyse, les auteurs traitent des principales techniques chirurgicales de reconstruction auriculaire, y compris la greffe de cartilage costal autologue, l'implant Medpor (Stryker, États-Unis) et la reconstruction prosthétique. Pour traiter des avantages et inconvénients de chaque technique, les auteurs ont invité les docteurs Nagata, Park, Reinish et Wilkes, chefs de file dans ce domaine, à commenter leur propre technique et à donner des exemples de leurs méthodes.

HEAR MAPS a classification for congenital microtia/atresia based on the evaluation of 742 patients.

OBJECTIVE: Describe anatomical and radiological findings in 742 patients evaluated for congenital aural atresia and microtia by a multidisciplinary team. Develop a new classification method to enhance multidisciplinary communication regarding patients with congenital aural atresia and microtia. METHODS: Retrospective chart review with descriptive analysis of findings arising from the evaluation of patients with congenital atresia and microtia between January 2008 and January 2012 at a multidisciplinary tertiary referral center. RESULTS: We developed a classification method based on the acronym HEAR MAPS (Hearing, Ear [microtia], Atresia grade, Remnant earlobe, Mandible development, Asymmetry of soft tissue, Paralysis of the facial nerve and Syndromes). We used this method to evaluate 742 consecutive congenital atresia and microtia patients between 2008 and January of 2012. Grade 3 microtia was the most common external ear malformation (76%). Pre-operative Jahrsdoerfer scale was 9 (19%), 8 (39%), 7 (19%), and 6 or less (22%). Twenty three percent of patients had varying degrees of hypoplasia of the mandible. Less than 10% of patients had an identified associated syndrome. CONCLUSION: Patients with congenital aural atresia and microtia often require the intervention of audiology, otology, plastic surgery, craniofacial surgery and speech and language professionals to achieve optimal functional and esthetic reconstruction. Good communication between these disciplines is essential for coordination of care. We describe our use of a new classification method that efficiently describes the physical and radiologic findings in microtia/atresia patients to improve communication amongst care providers.

Authorship conflicts: a study of awareness of authorship criteria among academic plastic surgeons.

BACKGROUND: Authorship is an important yardstick in academic medicine. The purpose of this study was to assess the prevalence of authorship conflicts among academic plastic surgeons and determine any change in authorship awareness over an 8-year period. METHODS: In 2003, members of the American Association of Plastic Surgeons were surveyed using an anonymous, 15-item, one-page questionnaire. In 2011, members were resurveyed using a similar questionnaire. In both surveys, nonresponders were contacted by telephone at 2 weeks to encourage response. RESULTS: The authors obtained a response rate of 80.4 percent (258 of 321) in 2003 and 81.6 percent (486 of 595) in 2011. In both cohorts, one-third of respondents felt that they had not been appropriately acknowledged as authors at some point during their career. Furthermore, in 2003, 29 percent of respondents admitted to being involved in a dispute with a colleague over authorship issues. This had decreased slightly to 22 percent by 2011. Interestingly, 64 percent of respondents in 2003, compared with only 37 percent of respondents in 2011, stated that they had included someone as an author who had not fulfilled any authorship criteria. In 2003, only 16 percent of respondents were aware of any journal authorship criteria. This had increased to 59 percent by 2011. CONCLUSIONS: The authors found an increase in awareness of authorship criteria among academic plastic surgeons in 2011 compared with those in 2003. In addition, academic plastic surgeons surveyed more recently reported more rigorous justification for including individuals as authors, supporting a trend toward increasing transparency and accountability.

Scalp as split thickness skin graft donor site for congenital atresia repair.

OBJECTIVE: Describe the use of the scalp as a donor site for split thickness skin grafts in otologic surgery. MATERIALS AND METHODS: Review of the literature with detailed description of surgical technique and authors' experience. RESULTS: One hundred and forty- four scalp split thickness skin grafts were obtained between 2007 and 2011. No significant complications were observed with optimal cosmetic results. CONCLUSIONS: The scalp is a viable option as a split thickness skin graft donor site for otologic and other head and neck surgery. Advantages include improved cosmetic results at the donor site, quick healing with low complication rates, and easy accessibility in the operative field.

Hypertrophic scarring in cleft lip repair: a comparison of incidence among ethnic groups.

BACKGROUND: Although hypertrophic scar (HTS) formation following cleft lip repair is relatively common, published rates vary widely, from 1% to nearly 50%. The risk factors associated with HTS formation in cleft patients are not well characterized. The primary aim of this retrospective study of 180 cleft lip repairs is to evaluate the frequency of postoperative HTS among various ethnic groups following cleft lip repair. METHODS: A retrospective chart view of patients undergoing primary cleft lip repair over a 16-year period (1990-2005) by the senior surgeon was performed. The primary outcome was the presence of HTS at 1 year postoperatively. Bivariate analysis and multivariable logistic regression were used to evaluate potential risk factors for HTS, including ethnicity, type and laterality of cleft, and gender. RESULTS: One hundred and eighty patients who underwent cleft lip repair were included in the study. The overall rate of postoperative HTS formation was 25%. Ethnicity alone was found to be an independent predictor of HTS formation. Caucasian patients had the lowest rate of HTS formation (11.8%) and were used as the reference group. HTS rates were significantly higher in the other ethnicities, 32.2% in Hispanic patients (odds ratio [OR]: 3.51; 95% confidence interval [CI]: 1.53-8.85), and 36.3% for Asian patients (OR 4.27; 95% CI: 1.36-13.70). Sex, cleft type, and cleft laterality were not associated with increased rates of HTS. CONCLUSIONS: Differences in ethnic makeup of respective patient populations may be a major factor influencing the wide variability of reported HTS rates. Consideration should be given to potential prophylactic treatments for HTS in susceptible ethnic populations.

Guide to early surgical management of lip hemangiomas based on our experience of 214 cases.

BACKGROUND: Hemangiomas are the most common vascular lesions in infancy. The majority of hemangiomas occur on the face and cause significant parental distress because of their high visibility. Traditionally, they have been managed by a "watch and wait" approach due to their known propensity to improve significantly over time. This is a particularly difficult approach for hemangiomas of the lips due to their high visibility and their tendency to leave residual deformity even after resolution. METHODS: The authors performed a retrospective chart review of pediatric patients who underwent surgical excision of upper and lower lip hemangiomas at Children's Hospital Los Angeles between 1992 and 2006. RESULTS: The authors identified 214 patients with an average age of 23.6 months at the time of surgery. All patients had improvements in lip appearance, with minimal complications. No transfusions were required, and all but two patients (lip switch flaps for major tissue loss) were managed on an outpatient basis. Overall, complications were minimal, with a high degree of parent satisfaction. CONCLUSION: The authors conclude that many children would benefit from early excision and present guidelines for the early surgical management of lip hemangiomas.
