Development and Preliminary Evaluation of A Soft Tissue Microtia Simulator.

Surgical simulation has been used extensively for learning microtia reconstruction and has almost exclusively involved framework creation. However, soft tissue reconstruction in microtia is equally challenging and would benefit from a simulation platform. This study aimed to describe the development and preliminary evaluation of a high-fidelity soft tissue microtia simulator. Three-dimensional modeling software, fused deposition 3-dimensional printing, adhesive techniques, silicones, and polyurethane rubbers were utilized to create a right lobular-type microtia simulator that comprises skin, subcutaneous tissue, and cartilage. Two expert microtia surgeons performed a microtia reconstruction on the simulator and evaluated its value and realism using a Likert-type questionnaire. The surgeons utilized a previously developed synthetic framework and successfully performed the critical steps of the soft tissue reconstruction, including marking, incising, dissection, removal of the cartilage remnant, drain insertion, insertion of the framework, closing of the skin, and demonstration of the soft tissue conforming over the framework using suction. A preliminary assessment of the simulator demonstrated that the simulator is anatomically accurate, realistic, and highly valuable as a training tool. A high-fidelity soft tissue microtia simulator was successfully developed and tested. The simulator provides a valuable training platform for learning a critical component of microtia reconstruction.

A Bibliometric Analysis of the Most Cited Articles in Global Reconstructive Surgery.

BACKGROUND: A substantial global inequality exists between surgical need and the availability of safe, affordable surgical care. Low- and middle-income countries have the greatest burden of untreated surgical disease and addressing this inequity is the goal of the Global Surgery movement. Reconstructive surgery is a fundamental component of Global Surgery as it is central to the appropriate treatment of trauma, burns, wounds, and congenital malformations. The objective of this study was to analyze the most frequently cited articles in the field of global reconstructive surgery to understand the main publication trends. METHODS: The 25 most cited articles relating to global reconstructive surgery were identified from all available journals through the Web of Science online database. The following data were extracted from each included article: title, source journal, publication year, total citations, average citations per year, authors, main subject, reconstructive surgery subspecialty, country, and institution of origin. RESULTS: The average number of citations per article was 21.7 (median, 19; range, 10-40). Most articles originated from the United States, and only 1 originated from a low-income country. The majority of the articles focused on cleft lip and palate (CLP) (72%), with few articles discussing burns or trauma. The main discussion themes were the quality of care provided in low- and middle-income countries both by local and visiting teams, the burden of diseases in relation to global reconstructive surgery, and the impact of surgical interventions economically and on patients. CONCLUSIONS: The number of research articles and citations related to global reconstructive surgery are limited. Despite having a lower incidence than burns or trauma, there is a preponderance of reports focusing on missions treating CLP. These findings suggest that more research funding could be invested in global reconstructive surgery for conditions other than CLP.

Innovate Global Plastic and Reconstructive Surgery: Cleft Lip and Palate Charity Database.

BACKGROUND: There is an emerging interest in global surgery. The Lancet Commission on Global Surgery recognizes the important role that nongovernmental organizations (NGOs) play in the delivery of cleft lip and/or palate (CLP) surgical care. To better address the unmet burden of surgical disease, the commissioners propose the use of a centralized registry to maximize coordination of global surgical volunteerism efforts. This study aims to create a comprehensive database of CLP organizations. METHODS: A systematic search of the following resources was conducted: The Plastic Surgery Foundation, Smile Train, Wikipedia, Google, and lists of surgical NGOs. A secondary review of each organization's website was performed to verify inclusion criteria and to extract data. Organizations were classified as providing surgical or nonsurgical care. RESULTS: Thirty-one organizations providing CLP care were reviewed, with 30 that met inclusion criteria. Of the 20 surgical NGOs, 50% use a diagonal approach of international outreach, 40% a vertical one-way approach, and 10% a horizontal approach. All 10 of the nonsurgical NGOs provide care through a horizontal approach. Their offices are distributed across North America (43%), Asia (27%), Europe (23%), and Australia (7%). Forty-three percent of the organizations provide CLP surgeries or services in more than 1 country; 93% do so with a multidisciplinary team. A majority of the organizations established collaborations with host institutions (80%). CONCLUSION: To the authors' best knowledge, this database includes the largest collection of CLP organizations. This list will be made publicly available to inform surgical care planning, facilitate collaboration, and promote further research.

Can We Reach a Consensus on the Appropriate Use of Before and After Photos in Breast Surgery?

Breast surgery is an area of practice where patients value before and after photographs (BAPs). Consensus is needed to develop guidelines to address the deficit in the literature regarding appropriate use of BAPs, as these may ultimately play a significant role in the breast surgery consent process. METHODS: Expert breast reconstructive surgeons participated in a modified nominal group technique (NGT) to establish expert consensus on categories and criteria to be used when evaluating appropriate use of BAPs as part of informed consent. Endorsement rate of 75% and coefficients of variance within and between rounds were conducted to determine validity of each criteria item's rank order. RESULTS: Eight experts participated in the NGT in-person meeting and subsequent online survey. five of seven categories were endorsed for discussion: purpose, image type, anatomy, results, and photographic integrity. Overall consensus was obtained for six of 11 criteria. Criteria items found to have consensus were: patients considering surgery being the intended photograph audience (100% endorsement, CV1 - CV2 = 0.01), use of photographic images (75% endorsement, CV1 - CV2 = 0.04), defining the standard clinical photograph by having patients in the same body position (100% endorsement, CV1 - CV2 = 0.14), anonymizing images by removing all digital tags (88% endorsement, CV1 - CV2 = 0.03) and patient identifiers (75% endorsement, CV1 - CV2 = 0.00), not limiting the number of photograph sets needed for sufficient representation (100% endorsement, CV1 - CV2 = 0.07), and representing average outcomes (100%, CV1 - CV2 = 0.06). CONCLUSIONS: Early use of this validated and effective technique helps identify potential consensus categories and criteria that surgeons recommend for the use of BAPs in the informed consent process. Further study is required.

An international study to develop the EAR-Q patient-reported outcome measure for children and young adults with ear conditions.

BACKGROUND: There is currently a lack of patient-reported outcome measures for ear reconstruction. We developed the EAR-Q to measure ear appearance and post-operative adverse effects from the patient perspective. METHODS: Field-test data were collected from children and young adults in eight countries between 13 May 2016 and 12 December 2019. Rasch measurement theory (RMT) analysis was used to refine the scales and to examine their psychometric properties. RESULTS: Participants had microtia (n = 607), prominent ears (n = 145) or another ear condition (n = 111), and provided 960 assessments for the Appearance scale (e.g., size, shape, photos), and 137 assessments for the Adverse Effects scale (e.g., itchy, painful, numb). RMT analysis led to the reduction of each scale to 10-items. Data fit the Rasch model for the Appearance (X2(80) = 90.9, p = 0.19) and Adverse Effects (X2(20) = 24.5, p = 0.22) scales. All items in each scale had ordered thresholds and good item fit. There was no evidence of differential item function for the Appearance scale by age, gender, language, or type of ear condition. Reliability was high for the Appearance scale, with person separation index (PSI) and Cronbach alpha values with and without extremes ≥0.92. Reliability for the Adverse Effects scale was adequate (i.e., PSI and Cronbach alpha values ≥0.71). Higher scores (liked appearance more) correlated with higher scores (better) on Psychological, Social and School scales. INTERPRETATION: The EAR-Q can be used in those 8-29 years of age to understand the patient perspective in clinical practice and research, and in addition, can be used to benchmark outcomes for ear reconstruction internationally.

Development of a New Patient-reported Outcome Measure for Ear Conditions: The EAR-Q.

BACKGROUND: Patient-reported outcome measures are widely used to improve health services and patient outcomes. The aim of our study was to describe the development of 2 ear-specific scales designed to measure outcomes important to children and young adults with ear conditions, such as microtia and prominent ears. METHODS: We used an interpretive description qualitative approach. Semi-structured qualitative and cognitive interviews were performed with participants with any type of ear condition recruited from plastic surgery clinics in Canada, Australia, United States, and United Kingdom. Participants were interviewed to elicit new concepts. Interviews were audio-recorded, transcribed, and coded using the constant comparison approach. Experts in ear reconstruction were invited to provide input via an online Research Electronic Data Capture survey. RESULTS: Participants included 25 patients aged 8-21 years with prominent ears (n = 9), microtia (n = 14), or another condition that affected ear appearance (n = 2). Analysis of participant qualitative data, followed by cognitive interviews and expert input, led to the development and refinement of an 18-item ear appearance scale (eg, size, shape, look up close, look in photographs) and a 12-item adverse effects scale (eg, itchy, painful, numb). CONCLUSIONS: The EAR-Q in currently being field-tested internationally. Once finalized, we anticipate the EAR-Q will be used in clinical practice and research to understand the patient's perspective of outcomes following ear surgery.

Single-stage autologous ear reconstruction for microtia.

BACKGROUND: The authors have been using the Nagata technique since 2002. In this review of 100 consecutive ear reconstructions, the authors present technique modifications that have evolved over this period that have contributed to improved auricular contour and that now allow for auricular reconstruction in a single stage. METHODS: This study is a retrospective review of a prospectively acquired database. The series is restricted to primary reconstructions performed for congenital microtia. Photographs of 10 consecutive patients are presented to demonstrate the results of the technique. Surgical complication rates are discussed. RESULTS: One hundred ear reconstructions were performed in 96 patients. There were 75 primary cases of congenital microtia. Twenty-four ears underwent a two-stage reconstruction, and 51 ears were reconstructed with a Nagata stage I procedure or a single-stage reconstruction. There was a gradual shift in technique, with a trend to perform fewer Nagata stage II outsetting procedures and more single-stage reconstructions. In patients who underwent an ear reconstruction in two stages, the surgical complication rate was 22 percent. In the last 40 consecutive ear reconstructions since abandoning the two-stage approach, the surgical complication rate is now 15 percent. CONCLUSIONS: A modification of Nagata's technique of autologous ear reconstruction for microtia is described. Modifications of the three-dimensional framework address the contour of the inferior crus and control tragal projection and position. Inclusion of a projection block and recruitment of retroauricular skin allow for symmetric projection of the ear in a single stage. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

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.
