The Role and Versatility of the Temporoparietal Fascia Flap for Coverage of Cochlear Implant Extrusion.

The use of cochlear implants (CI) may be associated with different complications, being extrusion of the device one of the most common. Reconstruction of the defect with a healthy and vascularized tissue is often required. We present two patients with a CI extrusion treated with a temporoparietal fascia flap.

Conservative Management of a Rare Entity-Aplasia Cutis Congenita: A Case Report.

Aplasia cutis congenita (ACC) is a rare entity characterized by a congenital localized absence of the skin, dermal appendages, and subcutaneous tissue. The cause of ACC is not clear, but inheritance is the most widely accepted cause. We report a rare case of a full-term (37 + 5 weeks) female newborn who showed complete absence of skin in localized areas of the upper and lower extremities. The patient was diagnosed with ACC associated with epidermolysis bullosa (EB; a disease that causes the skin to blister easily) and was initially treated using conservative measures. We applied mupirocin topical ointment and a nonocclusive polyester mesh impregnated with hydrocolloid and petroleum jelly daily. Complete healing of the affected areas occurred after 3 weeks. Managing patients with ACC is often challenging and based on the severity of the lesions, the approach may include both surgical and conservative treatment. Our case report suggests that a conservative approach can be effective for managing certain types of ACC and EB lesions. However, further research is warranted to better understand the pathogenesis and optimal management of this entity.

Age and Breast Reconstruction.

BACKGROUND: Breast reconstruction is frequently offered to cancer patients who undergo mastectomy. Older women tend to have lower rates of reconstruction mostly due to an age-based discretion. We aimed to assess the safety of this surgery in this population. METHODS: We conducted a single-center retrospective analysis of patients who underwent breast reconstruction following mastectomy between 2015 and 2020 at "Complejo Hospitalario Universitario de Albacete." Patients were classified according to age when the reconstruction process began (group A: < 65 years-group B: > 65 years). Differences in demographics and clinical data were analyzed using Student's t test and Chi-square test. Multivariable logistic regression models were used to estimate odds ratio (OR) and confidence intervals (CIs) for surgical complications according to age group. Propensity-score matching was used as a sensitivity analysis to test consistency among results. RESULTS: We included 304 women (266: group A-38: group B). Complete reconstruction was achieved in 48.1% of patients in group A vs 10.5% in group B (P < 0.001). After adjusting for potential confounders, age was not associated with an increased risk of surgical complications, neither overall (OR 0.88, 95%CI 0.40-1.95), early (OR 1.35, 95%CI 0.58-3.13) nor late (OR 1.05, 95%CI 0.40-2.81). Radiotherapy and smoking history were significant predictors for complications in every setting. CONCLUSIONS: In our cohort, age at breast reconstruction is not associated with a higher risk of surgical complications, in contrast to radiotherapy and smoking history. Therefore, age should not be a limiting factor when considering breast reconstruction. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

A Free Tool for Breast Aesthetic Scale Computation.

BACKGROUND: Our work describes the concept of Breast Aesthetic Scale (BAS) as a score for quick and simple objective assessment of results in cosmetic breast surgery. It is obtained by running a software program that we created, based on the previous concept of Objective Breast Cosmesis Scale (OBCS). This was previously described to be used in the context of conservative breast cancer treatment to objectively assess the degree of asymmetry. We describe the implementation of BAS algorithm and study its reproducibility in a set of images. METHODS: A new multiplatform software was developed by us and named Breast Aesthetic Scale Calculator (BAS-Calc), which can be executed on Windows Mac, and Linux. A set of 25 photographs were studied with this software twice by 2 different surgeons. Intrarater and interrater variability were studied, as well as concordance with categorization by another symmetry assessment software available called Breast Analyzing Tool®. RESULTS: Concordance among raters was excellent (intraclass correlation coefficient = 0.953; Lin concordance and correlation coefficient = 0.950), as well as intrarater (0.952 and 0.965). Categorization of both systems (Breast Analyzing Tool and BAS-Calc) showed almost perfect concordance (Cohen κ = 0.920). CONCLUSIONS: Objective estimation of symmetry after breast surgery can be assessed with BAS-Calc. The "symmetric" and "asymmetric" categories are accurately discriminated by this free software, and it can be used by surgeons as a simple method for objective assessment of results in cosmetic breast surgery.

Visual Breast Asymmetry Assessment with Optical-Flow Algorithm.

Breast surgery is one of the most important procedures in cosmetic and reconstructive surgery. However, there is no ideal method to assess results. One of the greatest difficulties is the subjective aspect of evaluation. In recent years, several objective computer systems have been proposed and validated as assessment methods, such as BCCT®, OBCS®, GBAI©, etc. In this study, we propose a novel system named VIBA©, that uses an Optical Flow (OF) algorithm which objectively classifies results into symmetrical and asymmetrical categories, with a numerical score. Software was developed in MATLAB (MATLAB and Statistics Toolbox Release 2018b, The MathWorks, Inc., Natick, Massachusetts, USA) called VIBA-Calc© (VIBA stands for VIsual Breast Asymmetry). We compared our OF score with the well-established asymmetry scoring system called Objective Breast Cosmesis Scale (OBCS®). In order to do so, we studied 100 frontal photographs of patients who underwent aesthetic breast surgery between 2017 and 2018, from the senior author's private practice. VIBA-Calc© allows the user to load an image and then draw a rectangle containing both breasts. By simply clicking on a button, the program finds the midline of the rectangle and calculates the final score, as well as the color map of asymmetric regions. Classification into symmetric or asymmetric categories using OBCS and VIBA scores agreed in most cases. Concordance between both classification systems was almost perfect in the group of postoperative cases (k = 0.84; p < 0.001), and substantial in preoperative cases (k = 0.76; p < 0.001). Global Cohen's kappa coefficient was 0.80 (p < 0.001). VIBA© is a useful tool for pre- and post-operative evaluation of breasts, that could be used both in reconstructive and aesthetic surgery.

Use of Symmetry Assessment Methods in the Context of Breast Surgery.

BACKGROUND: Different procedures are available to help clinicians evaluate symmetry and cosmetic results in an objective manner after conservative breast cancer surgery. However, there are no similar methods in esthetic breast surgery, where the subjective assessment of the surgeon or the patient is usually considered the gold standard. The aim of this study is to evaluate the application of four software programs in the context of esthetic breast surgery and contrast their results with those of the subjective evaluation by a series of healthcare professionals. MATERIALS AND METHODS: Sixty cosmetic breast surgery images were studied using four software programs considered appropriate for the objective evaluation (BCCT3.core®, Breast Analyzing Tool®, Objective Breast Cosmesis Scale® and GBAI-Global Breast Asymmetry Index®). The same cases were assessed by a group of 100 health professionals through an online survey as a subjective evaluation method. RESULTS: Concordance among participants was high (κ = 0.753) as well as between three of the objective methods (BSI, OBCS, GBAI), but not with the BCCT parameter. There was no association between objective and subjective methods studied by the survey, according to the logistic regression model. The "symmetry" and "asymmetry" categories were accurately distinguished by the objective methods. CONCLUSIONS: Objective evaluation in esthetic breast surgery has less variability than subjective assessment, and the estimation is possible through certain software previously restricted to conservative breast cancer surgery.
