RESUMEN

BACKGROUND: In an era where globalization and social media significantly reshape beauty standards, it is imperative to delve into the subjectivity of beauty and attractiveness. The lips, a key element in facial aesthetics, contribute significantly to the perception of attractiveness, and also have a profound impact on an individual's self-esteem. OBJECTIVE: To analyze the influence of ethnicity on the aesthetic preferences for lip characteristics, among male and female faces. MATERIALS AND METHODS: This study encompassed a sample of 231 study participants (153 women and 78 men) with an average age of 23.2 ±â€¯2.8 years, representing ethnicities such as African, Caucasian, Middle Eastern, and South Asian. Participants were asked to rate a series of images showcasing various lip variants, providing insights into their aesthetic preferences. RESULTS: Demographic analysis revealed gender and ethnic variations in aesthetic preferences for all the investigated lip parameters. Women were 2.42 times more likely than men to prefer no Cupid's indentation on a female model (p = 0.0019). CONCLUSIONS: The study underscores the importance of understanding cultural influences on beauty standards and challenges the notion of a universal beauty ideal. The evolving role of social media trends, such as Cupid's bow indentation elimination, raises questions about the dynamic nature of aesthetic preferences among different ethnicities.

RESUMEN

BACKGROUND: The increasing number of esthetic procedures emphasizes the need for effective evaluation methods of outcomes. Current practices include the individual practitioners' judgment in conjunction with standardized scales, often relying on the comparison of before and after photographs. This study investigates whether comparative evaluations influence the perception of beauty and aims to enhance the accuracy of esthetic assessments in clinical and research settings. OBJECTIVE: To compare the evaluation of attractiveness and gender characteristics of faces in group-based versus individual ratings. METHODS: A sample of 727 volunteers (average age of 29.5 years) assessed 40 facial photographs (20 male, 20 female) for attractiveness, masculinity, and femininity using a 5-point Likert scale. Each face was digitally edited to display varying ratios in four lip-related proportions: vertical lip position, lip width, upper lip esthetics, and lower lip esthetics. Participants rated these images both in an image series (group-based) and individually. RESULTS: Differences in the perception of the most attractive/masculine/feminine ratios for each lip proportion were found in both the group-based and individual ratings. Group ratings exhibited a significant central tendency bias, with a preference for more average outcomes compared with individual ratings, with an average difference of 0.50 versus 1.00. (p = 0.033) CONCLUSION: A central tendency bias was noted in evaluations of attractiveness, masculinity, and femininity in group-based image presentation, indicating a bias toward more "average" features. Conversely, individual assessments displayed a preference for more pronounced, "non-average" appearances, thereby possibly pointing toward a malleable "intrinsic esthetic blueprint" shaped by comparative context.

RESUMEN

Macromastia is an excessive, rapid, or slow growth of breast tissue in 1 or both breasts. While macromastia represents a benign lesion, it may cause breast, shoulder, back, and neck pain, poor posture, infections, and loss of nipple sensation. The pathogenesis of macromastia or hypertrophy of mammary tissue remains poorly understood. The purpose of this study is to investigate the immunohistochemical expression of several hormone receptors that may potentially influence the growth of breast tissue in women with macromastia. Immunohistochemical studies performed on representative sections of breast tissue from 63 patients diagnosed with macromastia included estrogen receptor, progesterone receptor, androgen receptor (AR), prolactin receptor, growth hormone receptor, and vascular endothelial growth factor. The expression of each stain was evaluated separately in the glandular epithelium and adipose tissue and calculated as an H-score. We observed that AR expression in breast glandular and adipose tissue in women with macromastia was significantly lower than benign, nonhypertrophic breast tissue of a control group. Although the analyses were controlled for the age, the fact the mean age and hormonal status differed between the patients and the controls could have affected the results. Additional large studies will be required to further verify this finding and increase the knowledge about the etiology of this condition and then guide pharmacological treatment of juvenile and/or idiopathic gigantomastia.

RESUMEN

Background: Platelet-rich plasma (PRP) has been shown to support wound healing and tissue regeneration due to its high concentration of growth factors and cytokines. This study aims to investigate the effect of intraoperative PRP injections on the final appearance of vertical scars after breast reduction, as well as to identify potential predictors of a scar's aesthetic assessment using spectrophotometric parameters. Methods: In this prospective, randomized trial, 82 scars from 41 women who underwent bilateral breast reduction with an inverted T pattern were analyzed. PRP or a placebo substance (0.9% sodium chloride solution) was injected intraoperatively into the edges of vertical wounds. Spectrophotometric measurements of scar pigmentation were performed 3 and 6 months after surgery; additionally, two independent observers evaluated the aesthetic appearance of scars based on photographs. Results: The results showed that the use of intraoperative PRP injections did not significantly influence the final appearance of vertical scars after breast reduction. Conclusions: We indicated spectrophotometric variables (b) in the early stages of wound healing (after 3 months) that can be predictors of the final scar's aesthetic outcome. This can be helpful in detecting scars that may need additional interventions to optimize the healing process.

RESUMEN

INTRODUCTION: There has been a rising trend in the use of silicone breast implants for breast reconstructions after breast cancer treatment, as well as in the aesthetic breast procedures. A cluster of non-specific symptoms related to the presence of silicone implant has been called breast implant illness (BII). However, there are no strict criteria of BII which would specifically define this term. The increasing interest in BII among patients and physicians urges verifying own cases of "on-demand" explantations. MATERIAL AND METHODS: In this paper, we discussed a case of a patient with initial BII diagnosis, after breast reconstruction, and reviewed the literature on the BII symptoms and aetiology. A decision for aesthetic revision, not explantation, was made as the diagnosis of BII was questioned, and somatisation due to dissatisfaction with the aesthetic result of breast reconstruction was diagnosed. RESULTS: Improving aesthetics by implant exchange and contralateral mastopexy caused a full recovery from patient's symptoms. CONCLUSION: Based on our case, we point on the fact that BII diagnosis in patients after breast reconstruction is challenging. We suggest that while considering such a diagnosis and further proceedings, e.g. explantation, especially in patients after breast reconstruction, some exclusion criteria should be considered. Dissatisfaction with the result of the surgery can also lead to somatisation and the presence of real clinical symptoms, which should not be confused with the possible autoimmune reaction to silicone particles.

RESUMEN

BACKGROUND: The anterolateral thigh flap (ALTF) is a type of free flap which is commonly used in reconstructive surgery procedures and is based on the perforator from femoral circumflex artery. Some authors found that the location of the perforator differs between sexes. OBJECTIVE: To verify the influence of prenatal sex hormones (as measured by 2D:4D) on the morphology of the perforator of the descending branch of the femoral circumflex artery. METHODS: 88 participants (43 women) of a mean age of 28.5 years (SD 8.1 years) had the following measurements performed: height and weight; right and left-hand 2nd and 4th fingers' lengths; and distance from anterior superior iliac spine to the perforator from descending branch of lateral femoral circumflex artery related to the thigh length (right and left) (AP ratio). RESULTS: Right 2D:4D and Dr-l (right minus left 2D:4D) were dimorphic, similarly to AP ratio (right and left), which in women was significantly higher than in men. A significant correlation was found between right and left 2D:4D and location of the perforator of the left thigh in men. The higher right and left 2D:4D (more feminine) the higher the left AP ratio (more feminine). CONCLUSION: Our findings suggest that the location of perforator of femoral circumflex artery may be influenced by prenatal sex steroids such that low prenatal testosterone and high prenatal oestrogen are correlated to high AP (lower branching of the artery).

RESUMEN

BACKGROUND: To date, there are no studies that have analyzed the possible influence of exposure to prenatal sex hormones on the risk of laryngeal cancer (LC) and premalignant laryngeal lesion-vocal fold leukoplakia (VFL). Digit ratio (2D:4D) is suggested to be a proxy of prenatal sex hormone exposure. OBJECTIVE: To examine 2D:4D in patients with LC and clarify if it could add to the verified risk factors in estimating the overall risk of LC. METHODS: 511 subjects participated in the study. The study group included 269 patients: with LC (N = 114, 64 men) and VFL (N = 155, 116 men). Controls included 242 healthy individuals (66.40 ± 4.50 years (106 men)). RESULTS: Predictive models estimating the risk of VFL and LC in women, based solely on predictors like smoking and alcohol consumption had a lower area under the ROC curve (AUC) than the model with left 2D:4D. AUC for the model estimating the likelihood of VFL increased from 0.83 to 0.85, and for LC from 0.76 to 0.79. CONCLUSIONS: Low left 2D:4D may be associated with an increased risk of developing leukoplakia and laryngeal cancer in women. In the case of laryngeal cancer, left 2D:4D may serve as additional variable (to other known risk factors, such as smoking and/or alcohol consumption), which can improve cancer risk prediction.

RESUMEN

Plastic surgeons aim to achieve symmetry in breast surgeries, which is the main determinant of chest aesthetics. The aim of this study was to verify if preoperative breast asymmetry is a predictor of postoperative asymmetry in women undergoing breast reduction. In this prospective study, we enrolled 71 women (the mean age 37 years, SD 10 years) with breast hypertrophy who underwent reduction mammaplasty. We collected clinical data including age, height, weight, weight of the resected tissues, and performed pre and postoperative photographic documentation. The following measurements of both breasts were analyzed: volumes (vol), nipple-sternal notch distance (A-sn), difference between nipples' levels (A-A'), nipple-midline distance (A-ml), difference between inframammary folds levels (IF-IF'), distance between inframammary fold and nipple (IF-A), distance between inframammary fold apex and midline (IF-ml). All measurements were performed preoperatively and 6 months after the surgery and asymmetries of all variables were calculated (asy-vol, A-A', asyA-sn, asyA-ml, IF-IF', asyIF-A, asyIF-ml). Postoperative asymmetry of breast volumes and nipples position was not associated with any of the analyzed clinical variables. Postoperative asymmetry of nipples' level was associated with preoperative asymmetry of IF-ml; however, logistic regression did not detect any preoperative measurement influencing postoperative volume and nipples' level asymmetry. Moreover, we found that preoperative asyIF-ml increased the risk of postoperative volume asymmetry, which is above the average (52 cc) (OR = 2.04). Postoperative breast asymmetry after breast reduction is not related neither to preoperative asymmetries nor clinical variables; however, asymmetry of inframammary fold apex to the midline may be the factor affecting postoperative volumetric asymmetry.

RESUMEN

<b><br>Introduction:</b> The anterolateral thigh flap is an example of a free flap widely applied for reconstruction of tissues within various areas of the body.</br> <b><br>Aim:</b> The aim of the study was to determine the most common locations of the ALT flap perforators in men and women as well as to clarify any potential differences in the location of the vessel in male vs. female subjects.</br> <b><br>Material and method:</b> In years 2021-2022, a study was conducted at the Plastic, Reconstructive, and Aesthetic Surgery Clinic in a group of 90 volunteers (45 women and 45 men, a total of 180 lower extremities) to determine the location of the anterolateral thigh flap perforator against the flap surface using a portable Doppler probe.</br> <b><br>Results:</b> Variable locations were revealed for the anterolateral thigh flap perforator within the study. In women, the perforator is located more distally from the anterior superior iliac spine, most frequently within the inferolateral quadrant, while being located closer to the anterior superior iliac spine, and most frequently within the superolateral quadrant, in men. No perforator was found in 3.3% of the examined limbs. No statistically significant differences were observed between the course of the perforators within the left and right lower limbs in individual patients.</br> <b><br>Conclusions:</b> The location of the ALT flap perforator is subject to sexual dimorphism, which facilitates the investigation area being narrowed down to the well-defined locations of its most frequent occurrence when planning anterolateral thigh flap reconstructive procedures.</br>.

RESUMEN

BACKGROUND: A number of studies have reported breasts have high fluctuating asymmetry (FA:|Right-Left|), suggesting that they contain evolutionary and clinical information (e.g., high FA correlates with breast cancer risk). Here we focus on breast FA in women with a wide range of breast sizes, including participants with macromastia and/or gigantomastia. MATERIAL AND METHODS: The sample included 65 women (mean age 33.97 ± 12.1 years). Thirty were randomly selected students and/or patients who regarded their breast size as small, normal or average and who had not undergone or intended to have any breast surgery. The remainder (n = 35) were qualified for breast reduction due to macromastia and/or gigantomastia. In all participants we measured/calculated weight, height and BMI, as well as took chest photographs. Breast volumes and nipple areola complex FAs were evaluated in a specifically-designed software. RESULTS: Breast size significantly positively correlated with breast volume FA in all women (t = 5.17, p < 0.0001) and in women with macromastia/gigantomastia (t = 2.32, p = 0.027). All nipple location FAs correlated positively with breast size. CONCLUSIONS: In women with different breast sizes, breast size correlates with FA calculated from breast volume and nipple location FAs. In women with macromastia and/or gigantomastia, breasts present higher FA than "normal" breasts. This observation may give a rationale for earlier and more frequent prophylactic breast imaging in women with macromastia and/or gigantomastia.

RESUMEN

The aim of this report is to present a case of a patient who developed unusual systemic hypersensitivity reaction to a red-pigmented tattoo and to discuss diagnostic difficulties in case of systemic reactions to tattoo ink. The patient reported erythroderma on his arms and chest accompanied by plaque elevation of red parts of his most recently performed forearm tattoo as his primary symptoms. His health condition entailed a prolonged topical and intravenous immunosuppressive therapy, which proved ineffective. Over a year after emergence of initial symptoms, he presented to the Plastic Surgery Clinic with generalized erythroderma, systemic lymphadenopathy, elevation and granuloma formation in red tattoos on his forearm and complaints of fatigue and inability to participate fully in work-related and social activities. The patient underwent six staged excisions with direct closures, flap plasties and full-thickness skin grafts. Following completion of each surgical resection, the patient's symptoms gradually subsided. We find this case illustrative of a clinical challenge that delayed hypersensitivity reactions to red tattoos may pose. Furthermore, we provide insights on management of hypersensitivity reactions. This report underlines the importance of social awareness of and public health approach to tattoo complications as key to successful prevention, identification and treatment of adverse reactions to tattoos.

RESUMEN

Introduction: Gigantomastia is a rare condition characterised by excessive breast growth. The pathophysiology of mammary enlargement varies depending on the type of gigantomastia: gestational, juvenile virginal, or idiopathic. The study aimed at examining the receptor status (oestrogen receptor α (ERα) and progesterone receptor (PR)) of breast tissue in adult women with juvenile or idiopathic gigantomastia. Material and methods: The study involved 70 women who underwent breast reduction due to juvenile or idiopathic gigantomastia. Control breast specimens were obtained from 18 female cadavers. ERα and PR expressions were detected immunohistochemically in breast gland samples. Results: Categorised and uncategorised ERα and PR expression did not differ between women with gigantomastia and control women. It was found that in both groups weak (0-30%) ERα and PR expression was the most common. Analysis of categorised data also did not reveal any significant correlations between ERα or PR and the women's age: for the whole group: p = 0.795 (ERα), p = 0.207 (PR), for women with gigantomastia: p = 0.934 (ERα), p = 0.43 (PR), and for control women: p = 0.638 (ERα), p = 0.805 (PR). Conclusions: Gigantomastia is not caused by increased expression of ERα and PR. Analysing abnormal sensitivity of these receptors to hormones may be crucial in establishing the increased risk of breast cancer in women with gigantomastia.

RESUMEN

Hashimoto thyroiditis and Graves' disease are autoimmune thyroid diseases which occur much more frequently in women than in men. Estrogen receptors are found in the thyroid gland and can modulate the gland's function. Digit ratio (2D:4D) is thought to be a negative correlate of prenatal testosterone and a positive correlate of prenatal estrogen. This study aimed to examine a relationship between right and left 2D:4D in women with Hashimoto thyroiditis and Graves' disease. The cross-sectional study included 106 women with autoimmune thyroid disease: 73 women diagnosed with Hashimoto thyroiditis and 33 women with Graves' disease, together with 70 healthy women as controls. Second and fourth digit length, weight, height were measured directly, and 2D:4D and BMI were calculated. Compared to controls, right and left 2D:4D were significantly higher in women with Hashimoto thyroiditis and lower in women with Graves' disease, the effects were higher for right 2D:4D. The mean length of right 4D was significantly lower in the examined women with Hashimoto thyroiditis than in Graves' disease. Higher right and left 2D:4D in women with Hashimoto thyroiditis suggests that prenatal exposure to high levels of estrogens relative to testosterone may play a role in the development of this disease. Lower right and left 2D:4D in women with Graves' disease suggest a role of high prenatal androgens relative to estrogens in Graves' disease pathogenesis.

RESUMEN

The role of estrogen, progesterone, their receptors and aromatase in the development of the breast is well documented. In this study we examined the association of genetic variants of progesterone receptor (PGR) and aromatase (CYP19A1) genes with gigantomastia risk. We conducted a case-control study among 124 women: 60 with gigantomastia and 64 controls. We examined the single nucleotide polymorphisms (SNPs) for CYP19A1 (rs749292 and rs7172156) and PGR (rs1042838). Our results showed that allele G in rs749292 (CYP19A1) increased the risk of gigantomastia, but not significantly (p = 0.09). There is a correlation between rs1042838 (PGR) and waist-to-hip ratio (WHR) in women with gigantomastia-AC genotype correlates with lower WHR and CC with higher WHR. There were no correlations between the onset of gigantomastia, the age of menarche and the length of the menstrual cycle, and rs1042838, rs749292 and rs7172156. We did not find differences in the SNP of PGR (rs1042838) between women with gigantomastia and controls. However, our findings showed more frequent G allele in CYP19A1 (rs749292) in women with gigantomastia.

RESUMEN

In 1922, Max Thorek described the method of breast reduction with the transfer of the nipple-areola complex as free grafts. Initially, this method met with quite a lot of criticism. Therefore, the search for solutions guaranteeing better aesthetic results of breast reduction have been evolved.The aim of the study is to present our own experiences related to the Thorek method of breast reduction in patients with gigantomastia and to consider whether this technique is still relevant in the 21st century.The study included women operated on for large breasts at the Plastic, Reconstructive and Aesthetic Surgery Clinic between 2012-2021. In the analysis 95 women aged 17 to 76 were involved.In the analyzed group of 95 women, 14 patients underwent breast reduction with transfer of the nipple-areola complex as a free graft (modified Thorek's method). In the remaining 81 cases, breast reduction was performed with the transfer of the nipple areola complex on the pedicle (upper-medial - 78, lower - 1, upper-lower - McKissock's method - 2).The usage of Thorek's method is still actual in a selected group of women. This technique seems to be the only safe one in patients with gigantomastia, with a high risk of nipple-areola complex necrosis related to the distance of nipple transfer, as well as after the end of the reproductive period. Its main disadvantages (tendency to breasts being too wide and flat, unpredictable nipple projection and nipple pigmentation) can be minimized by modification of the Thorek method or minimally invasive follow-up techniques.

RESUMEN

Breast volume assessment is crucial in a breast surgeon's clinical practice. The aim of this study was to present and validate a new Web application, BreastIdea Volume Estimator, a module for breast estimation of the already validated BreastIdea application. Forty breasts in 20 women were scanned using a three-dimensional scanner. They were then photographed in nonstandardized conditions, and volume estimations were calculated using BreastIdea Volume Estimator. Accuracy in addition to relative and absolute reliability of BreastIdea Volume Estimator measurements were investigated. In addition, breast volume differences were analyzed. Breast volume estimation using BreastIdea Volume Estimator yielded satisfactory accuracy and presented precision of the level of clinical measures. The mean absolute difference for both observers was 4.33 ± 3.79 cc and 6.78 ± 4.66 cc, which correspond to 1.87 ± 1.89 percent and 2.75 ± 2.05 percent errors of measurement. Similar relations were found for measurements of breast volume differences. BreastIdea Volume Estimator is a clinically oriented, reliable tool for breast volume evaluation. It provides results of appropriate accuracy regardless of chest abnormality and photograph standardization.

RESUMEN

A prenatal sex steroid environment of high prenatal testosterone and low prenatal oestrogen inhibits lung development and may predispose individuals to be vulnerable to lung disease in later life. Therefore, the aim of this report was to investigate whether there is an association between right and left 2D:4D (biomarker of prenatal sex steroids exposure) and primary lung cancer in women and men. Also, we considered the relationship between right-left 2D:4D (Δ2D:4D, a negative correlate of high prenatal testosterone and low prenatal oestrogen) and the age of lung cancer diagnosis. The study included 109 patients (61 men) with lung cancer and 197 controls (78 men). In the study we found that: (i) women with lung cancer have lower 2D:4D compared to controls (the effect was independent of smoking), (ii) among women with cancer, age at diagnosis was positively related to 2D:4D, i.e. women with masculinized 2D:4D present earlier with the cancer than women with feminized 2D:4D, (iii) among men with lung cancer, those with the most aggressive form (small-cell lung cancer) had masculinized (low) Δ2D:4D compared to those with the less aggressive form (non-small cell lung cancer). The data suggests that masculinized right 2D:4D and Δ2D:4D are associated with a predisposition to lung cancer and/or the more aggressive forms of lung cancer.

RESUMEN

Background Juvenile breast hypertrophy is characterised by massive enlargement of the breast in the peri-pubertal period. We aimed to analyse body size measurements (body mass index [BMI], waist-to-hip circumference ratio [WHR]), digit ratio (ratio of II and IV digits' length [2D:4D]) and oestrogen receptor (ER) alpha (ERα) and progesterone receptors (PRs) in the breast gland in women with juvenile gigantomastia. Methods The study involved 30 women (mean age 25.7 years) (mean age of onset - 14.8 years). ERα and PR expressions were detected immunohistochemically in breast gland samples. For comparison, 100 controls (50 women and 50 men) were included. Results BMI and WHR in women with gigantomastia were higher than in control women and the former had a higher WHR than expected for their BMI. 2D:4D in the examined women did not differ from that in control women. However, left 2D:4D was negatively related to the age of gigantomastia onset. There were no correlations between ER and PR expressions and the analysed body and digit ratios. Conclusions The lack of a relationship between 2D:4D and juvenile breast hypertrophy may suggest that foetal exposure to sex hormones may not be crucial in its aetiology. However, the link between high left 2D:4D and early development of gigantomastia suggests that prenatal sex hormones have a role in its development timing. High WHR, and particularly high WHR relative to BMI, may indicate that these women had at some stage of development higher circulating androgens, which may have been converted to oestrogens in breasts due to local aromatase activity. Verification of this hypothesis could allow consideration of the role of aromatase inhibitors in juvenile breast hypertrophy.

RESUMEN

BACKGROUND: Parry-Romberg syndrome (PRS) is a rare condition involving self-limited progressive facial hemiatrophy. AIMS: To analyze esthetic results of fat graft used for correcting soft-tissues atrophy in PRS patients, in the aspect of volume restoration and skin rejuvenation, to present our experience in redefining facial contours in PRS and modification of fat graft accusation technique (based on Coleman's technique). PATIENTS/METHODS: A prospective evaluation study was designed to analyze esthetic results (contour and skin condition), complications, and subjective satisfaction of eight patients with PRS treated with fat graft. RESULTS: All patients underwent two (n = 6) or three (n = 2) procedures in 3 months intervals (the mean 3.7 months). No major postoperative complications were observed. The authors evaluated their esthetic results concerning face contour and symmetry as good (in four patients) and very good (in four patients). Subjective assessment showed high patients' satisfaction with the final result of face contouring (the mean VAS [0-5]-4.75). CONCLUSIONS: Our experience shows that fat grafting in patients with PRS is safe and gives satisfactory results in the aspect of volume restoration and skin quality improvement. Modified technique of graft preparation (112 g for 3 minutes) enables to obtain less dense fat graft, which is more appropriate in case of PRS patients with thin atrophic skin.

RESUMEN

INTRODUCTION: Anthropometric measurements of breasts are crucial for planning surgical procedures; however, there are no practical solutions for their quick, digital performance. The aim of the study was to present and validate a self-designed web application BreastIdea (BI) designed for indirect breast anthropometry. METHODS: Ten male and 10 female volunteers had their chests measured directly according to the routine clinical practice. Then their chests were photographed in non-standardised conditions. Corresponding measurements were performed using BI. Accuracy and both relative and absolute reliability of BI measurements were investigated. RESULTS: Breast assessments using BI yielded highly accurate results and presented near-perfect precision when compared to direct anthropometric measurements of the breast. Indirect anthropometry eliminates the necessity to trace the body's curves, which usually introduces a bias to linear measurements. CONCLUSION: BI web application is a reliable tool for indirect breast measurements in a clinical setting, providing accurate results regardless of chest pathology and photograph standardisation.
