Morphological signs of neurogenic inflammation in rat epicardial adipose tissue during aging

The aim of this work is to study the neuroinflammatory process in the epicardial adipose tissue (EAT) of the aorticpulmonary region of the rat heart during aging. The work was performed on Wistar rats aged 18-23 months (n=18). The adipose tissue of the pericardial region of rats was the object of study. Neuroimmunohistochemical markers (9.5 protein, tyrosine hydroxylase, synaptophysin) were used to study EAT innervation. The method of staining with toluidine blue and azure-eosin was used to study inflammation processes. Using histological and immunohistochemical methods, involutive and neurodegenerative changes in parasympathetic and sympathetic postganglionic nerve fibers were revealed in the white and brown adipose tissue of the heart of old rats (18-23 months old). A number of pathological changes were revealed in EAT: fibrosis, dystrophic changes and lysis of white adipocytes, disintegration of varicose axons of the terminal nerve plexus, as well as the formation of focal monocyticlymphoid infiltrates. It has been shown that the axons of the terminal nervous network are in close relationship with immune and inflammatory cells (lymphocytes, plasmablasts, monocyte-macrophage elements, mast cells). The noted morphological features indicate a neurogenic type of immune inflammation in the EAT of the heart. The identified changes may be the cause of chronic disorders of lipid metabolism during aging, leading to the development of pathological processes in the tissues of the main vessels of the aortic-pulmonary region of the heart, and also serve as prognostic indicators for clinical practice.

Ultrasound examination of mammary glands in patients with infertility on background violations of menstrual function

The objective. Іs to investigate the state of the mammary glands in patients with infertility of endocrine genesis. Materials and methods. The study was conducted in 110 patients with endocrine infertility who underwent an ultrasound examination of the mammary glands. The first group (n=52) consisted of patients with a regular menstrual cycle against the background of luteal phase insufficiency, the second group (n=58) consisted of patients with a menstrual cycle disorder with anovulation. Statistical processing of the research results was carried out using the standard programs "Microsoft Excel 5.0" and "Statistica 8.0". Results and their discussion. Changes in the mammary glands according to the type of PCH in the studied group were found in 44 out of 110 patients (40.0%), underdevelopment of the structural elements of the mammary glands - in 19 out of 110 (17.3%), early involutional changes - in 6 out of 110 (65, 4%), focal formations – in 4 out of 110 (3.6%). The frequency of fibrocystic disease in patients of the II group was 1.3 times higher compared to the I group - 24 (41.3%) versus 20 (38.4%), respectively, p<0.01. At the same time, focal mammary gland formations of the fibroadenoma type were diagnosed 3.5 times more often in patients of the I group - 3 (5.8%) versus 1 (1.7%) in the II group, p<0,01. Conclusions. In infertility of endocrine genesis, the first place in the structure of mammary gland pathology is diffuse fibrocystic disease - 40.0%. The frequency of underdevelopment of mammary glands is 17.3%, early involutional changes 10.3%, and focal formations like fibroadenoma are 3.6% of cases.

ASSESSMENT OF THE RATIONALITY OF PHARMACOTHERAPY IN ELDERLY PATIENTS WITH CARDIOVASCULAR DISEASES USING STOPP/START NON-COMPLIANCE MODELS

Elderly patients, due to involutive changes in the body, have peculiarities of pharmacokinetics and pharmacodynamics, which must be taken into account when prescribing drugs. There are various tools for individualizing therapy: use the 7-step algorithm, STOPP/START criteria, anticholinergic load scales, assessment of triggers of undesirable events - GerontoNet scale, Brighton Adverse Drug Reactions Risk scale. The article examined the use of STOPP/START criteria by physicians in practical activities. It is determined that doctors pay more attention to STOPP criteria when treating the patient and prescribing drugs. It is determined that doctors pay more attention to STOPP criteria when treating the patient and prescribing drugs. Based on the data obtained during the assessment of the use of the rational pharmacotherapy tool, prognostic non-compliance with the criteria was calculated and the factors affecting this were determined: BMI for (for STOPP criteria) and a score on the Age Not Hindrance questionnaire (for START criteria).

Modern approaches to the correction of age-related skin changes in women

The article is devoted to the literature review on the correction of age-related skin changes in women. Skin aging is a physiological process that is caused by the constant action of unmodified factors, for example, endocrine disorders, shortening of telomeres, etc., in combination with periodic influence of modified (exposomal) factors. Ultraviolet radiation takes first place among external factors affecting the progression of degenerative changes in skin, however, in women, involutional changes in skin are primarily associated with a fading of synthetic function of ovaries. During the first five years from the onset of menopause, content of collagen fibers I and III types is reduced by 30% in combination with a further reduction of 2% annually for the next 15 years.Involutive transformations occur in all layers of skin and are visually characterized by the presence of wrinkles, roughness of the epidermal surface (with photoaging) or a decrease in its thickness (with chronic aging), dryness, pigmentation disorders in the form of uneven hyperpigmented spots, telangiectasias, oval deformations.Today, there are many methods of aesthetic correction of age-related skin changes. In the arsenal of a cosmetologist there are both invasive (PRP-therapy, microneedling, microneedle radio wave lifting, administration of preparations based on calcium hydroxyapatite, polylactic and hyaluronic acid, etc.) and minimally invasive (administration of botulinum neuroprotein, application of chemical acid peelings, IPL-therapy and laser polishing, photodynamic therapy) methods. Patients prefer minimally traumatic procedures due to the fact that they almost do not disturb the processes of socialization, however, each of these methods has both advantages and disadvantages.Modification of a woman life quality in peri- and menopause in form of changes in lifestyle and eating behavior, increasing physical activity, quitting smoking and limiting the use of alcoholic beverages is an integral part of therapeutic care. However, the appointment of menopausal hormonal therapy, including the use of estrogens, progestogens and combined hormonal drugs, allows to achieve a stable and long-lasting effect from cosmetology procedures and home care.

Relationships between anthropometric and body composition characteristics and age in Polish women over 60 as affected by their socioeconomic and health status and physical activity levels.

Background: Little is known about changes in anthropometric and body composition (A&BC) characteristics during the aging process. Research indicates that body composition can be linked with socioeconomic status (SES), health status (HS), and physical activity (PA) levels. Aim: The aim of this study was to evaluate age-related changes in A&BC characteristics in female seniors aged 60+ in view of their SES, HS, and PA levels. Methods: The survey was conducted in November and December 2022 on a total of 661 female seniors. A questionnaire survey was conducted to obtain information about the participants' socioeconomic status (chronic diseases, health status, marital status, membership in social organizations, financial status, place of residence, education). The respondents' PA levels were assessed with the International Physical Activity Questionnaire (IPAQ), and their A&BC characteristics were determined in a bioelectrical impedance analysis with the InBody 270 body composition analyzer. The relationships between A&BC characteristics and age were evaluated based on the values of the Pearson correlation coefficient (r). Results: The mean values of Percent Body Fat (PBF), Body Mass Index (BMI), and the waist-hip ratio (WHR) were relatively high (37.2%, 28.5kg/m2, and 0.8, respectively) and indicative of overweight and gynoid obesity. A higher number of significant negative correlations between A&BC characteristics and age were observed in seniors with lower values of SES, HS, and PA, which points to more rapid involutional changes in this group of respondents. A segmental analysis also revealed significantly lower values of fat-free mass (FFM) and body fat mass (BFM) (both indicators were calculated in percentage and kg), in particular in the upper limbs, in women with lower SES, HS, and PA levels. Conclusion: Environmental factors, including biological, physiological, environmental, psychological, behavioral, and social factors, are significantly associated with aging in women. Age-related changes in A&BC characteristics tend to proceed more rapidly in female seniors with low values of SES and HE and insufficient PA levels.

Pediatric hepatic vascular tumors: clinicopathologic characteristics of 33 cases and proposed updates to current classification schemes

Pediatric hepatic vascular tumors (HVTs) are rare neoplasms with features distinct from their cutaneous counterparts. Their behavior ranges from benign to malignant, with each subtype having therapeutic differences. Histopathologic descriptions of large cohorts are scarce in the literature. Thirty-three putative HVTs diagnosed from 1970 to 2021 were retrieved. All available clinical and pathologic materials were reviewed. Lesions were reclassified according to the World Health Organization (WHO) classification of pediatric tumors [1] ashepatic congenital hemangioma (HCH; n=13), hepatic infantile hemangioma (HIH; n=10), hepatic angiosarcoma (HA; n=3), and hepatic epithelioid hemangioendothelioma (HEH; n=1). Vascular malformations (n=5) or vascular-dominant mesenchymal hamartoma (n=1) were excluded. HCH frequently showed involutional changes, whereas HIH often had anastomosing channels and pseudopapillae formation. HA had solid areas with epithelioid and/or spindled endothelial morphology, significant atypia, increased mitoses, high proliferation index, and occasionally necrosis. On morphology analysis, a subset of HIH showed features worrisome for progression to HA including solid glomeruloidproliferation, increased mitoses, and epithelioid morphology. The widely metastatic and fatal HEH was observed in a 5-year-old male with multiple liver lesions. Immunohistochemically, HIHs and HA were Glucose transporter isoform 1 (GLUT-1) positive. One HIH patient died from postoperative complications, whereas 3 are alive without disease. Five HCH patients are alive and well. Two of three HA patients died of disease, and 1is alive without recurrence. To our knowledge, this is the largest series of pediatric HVTs reviewing clinicopathologic features based on current Pediatric WHO nomenclature [1]. We highlight diagnostic challenges and propose inclusion of an intermediate category between HIH and HA which warrants closer follow-up.

Anti-aging technologies and physiotherapy innovations

The aim of the study is to improve the quality of medical and aesthetic care for patients with age-related changes in the skin of the face and body by including injection carboxytherapy and platelet injection technique (PRP) in the treatment protocol. Material and methods. 81 patients (42 women and 39 men) with age-related involutive changes in facial skin were examined. All patients were examined using dermatological methods: corneometry, dermatoscopy, pH assessment, ballistometry and cutometry. All patients were randomized into comparison groups: the main group (20 patients) received injection carboxytherapy and platelet method (PRP), the control group (20 patients) did not receive methods of apparatus physiotherapy, two comparison groups (comparison-1, 20 patients) received injection carboxytherapy and (comparison-2, 20 patients) received the platelet method (PRP). Statistical data analysis was carried out in Microsoft Office Excel (2017) and SPSS statistical processing (PASW Statistics version, 2018). We used parametric (linear correlation method, Student's t-test) and non-parametric methods (Spearman's rank correlation coefficient, unpaired Wilcoxon-Mann-Whitney test and paired Wilcoxon test). Differences were considered significant at p < 0.05. Results. After the complex therapy, a significant increase in the hydration index of the facial skin by 12.8±1.1 units, an increase in the level of elastin by 9.4±2.9 units was noted, which contributed to a decrease in the depth of wrinkles after the combined method of injection carboxytherapy and PRP - by 1.4 points.

Possibility of stimulation of cerebral angiogenesis and neurogenesis with transcatheter intracerebral laser photobiomodulation therapy during dementia in patients with Alzheimer’s disease and in patients with distal cerebral atherosclerosis

AbstractBackgroundThe research is dedicated to stimulation of cerebral angiogenesis and neurogenesis with Transcatheter Intracerebral Laser Photobiomodulation Therapy (PBMT) in patients with dementia during Alzheimer’s disease (AD) and patients with distal forms of cerebral atherosclerosis.Materials & Methods350 patients with dementia were examined.We carried out determination of CDR, Tomography Dementia Rating scale (TDR), MMSE, cerebral CT, MRI, SG, rheoencephalography (REG), cerebral MUGA.48 (13.71%) patients with AD aged 34‐80 (mean age 67.5) were selected: 17 men (35.42%), 31 women (54.58%). According to their dementia severity, the patients were subdivided: preclinical stage (TDR‐0) ‐ 4, mild stage (TDR‐1) ‐ 16, moderately severe stage (TDR‐2) ‐ 21, severe stage (TDR‐3) ‐ 7.302 (86.29%) patients with distal cerebral atherosclerosis aged 58‐81 (mean age 78) were selected: 226 men (74.83%), 76 women (25.17%). According to their dementia severity, the patients were subdivided: mild stage (СDR‐1) ‐ 284 (94.04%), moderately severe stage (СDR‐2) ‐ 18 (5.96%).At hospital, all the patients underwent PBMT.ResultsAll 48 (100%) patients with AD showed improved cerebral microcirculation and 10‐20% increase in the volume of cerebral temporal lobes, which indicates cerebral neurogenesis development and tissue regeneration. The process was accompanied by a decreased level of dementia and restoration of cognitive functions. Consequently, the patients were transferred to milder TDR groups. Depending on the initial dementia severity, the resulting positive effect was observed during 2‐10 years.All 302 (100%) patients with distal cerebral atherosclerosis showed improved cerebral microcirculation and declining cerebral involutional changes, which indicates neurogenesis development and tissue regeneration. The process was accompanied by a decreased dementia level and cognitive functions restoration. The resulting positive effect was observed for over 10 years.ConclusionsDespite differences in the etiology of AD and distal cerebral atherosclerosis, PBMT is an effective treatment for dementia in these diseases. The method improves the blood supply of the brain; it stimulates neurogenesis and tissue structures restoration, which leads to an improvement in mental and cognitive functions. The resulting effect persists for a long time.

Исследование предоперационной симметрии дистанции «экватор хрусталика – цилиарные отростки» у пациентов с сочетанием возрастной катаракты с клиническими проявлениями инволюционной соединительнотканной дисплазии

Purpose. Study of state of the Zonule of Zinn in patients with combination senile cataract with systemic involutional connective tissue dysplasia. Material and methods. 97 patients (97 eyes) – combination senile cataract with involutional pathology in connective tissue (the main group). 1st subgroup: 31 patients with kyphoscoliotic deformity of the 3d and 4th degree (classification by V.D. Chaklin (1973)); 2nd subgroup – 66 patients with chronic venous insufficiency 2nd and 3d degree (the CEAP classification) against the background of varicose veins of the lower extremity. Patients of both subgroups were comparable in terms of cataract stages and nuclear cataract lens density in Buratto classification. The control group – 55 patients (55 eyes) similar sex and age with senile cataracts without involutional connective tissue pathology. We estimated the symmetry of distance «lens equator – ciliary processes» in 2 meridians: at 6 and 12 hours. The presence of asymmetry of 0.3 mm or more was sign of weak zonular support (according to ultrasonic biomicroscopy). Results. In the control group, the distance was 0.3 mm in 3 eyes (5%), with intraoperative formation of folds in the anterior capsule. In 10 eyes of the 1st subgroup of the main group (32%), the presence of distance asymmetry was revealed: intraoperative, signs of subluxation of the lens of the 1st degree were detected in 7 eyes. In the 2nd subgroup of the main group, distance asymmetry was detected in 24 eyes (37%). Folded anterior lens capsule was determined intraoperative in 14 eyes (21%) during anterior capsulorhexis and lens mobility during nucleus emulsification. Conclusion. A statistically significant difference in frequency of asymmetries of distances «lens equator – ciliary processes» in 2 opposite meridians was revealed between groups of patients with senile cataract against the background of systemic somatic involutional pathology of connective tissue and without it (35% vs. 5%; p < 0.01). Keywords: senile cataract, Zonule of Zinn, involutional changes in connective tissue, ultrasound biomicroscopy

Features of the Peribiliary Glands of the Extrahepatic Biliary Tract in the Elderly and Long-Living Individuals

The aim of the study was to analyse histologically and morphometrically the peribiliary glands of the extrahepatic biliary tract in the elderly and long-living people.Material and methods. The study included wholemounts of the gallbladder, the cystic, hepatic and common bile ducts obtained from the corpses of both sexes aged 22 to 35 years (n=16) and older than 76 years (n=39). Macro-microscopy was used to evaluate the number, localization, sizes and shape of the glands, the area of the lumen of the excretory duct orifices, the area of the initial section of the glands, the number of initial (terminal) parts and the proportion of epithelial parenchyma in their composition.Results. With age, there is a decreased proportion of "complexly branched" glands with a significant number of initial sections and excretory ducts of the 1st order. The proportion of "simple" glands, with one initial section increases to 70.2–78.3% in the senile age, while it is 41.0–52.1% in people of mature age. In long-living people, there is an increased number (up to 70–85%) of glands with ampullar extensions of the common excretory duct. The total number, density of gland localization, the length and width of the initial section of the peribiliary glands tend to decrease from the period of mature age to longevity. In senile age, the size and quantitative parameters of the glands stabilize, and do not modify in long-living people.Conclusion. The results of the morphological analysis demonstrate that there is no progression of involutive changes in the peribiliary glands of the extrahepatic biliary tract from senile age to the period of longevity. In some cases, long-living individuals manifest compensatory-adaptive reactions, such as an increased severity of the epithelial parenchymal component in the composition of the glands and an increased proportion of glands with an ampullar expansion of the common excretory duct.

EVALUATION OF KIDNEY FUNCTION IN AN ELDERLY PATIENT WITH ACUTE MYELOBLASTIC LEUKEMIA AFTER HEMATOPOIETIC STEM CELL TRANSPLANTATION: A CASE REPORT

Relevance: Kidney functions in treating acute myeloblastic leukemia (AML) undergo serious effects, especially in elderly patients. Chemotherapeutic drugs used to prepare for hematopoietic stem cell transplantation (HSCT) inevitably affect elderly patients’ kidney function. Moreover, involutive changes in the kidneys can physiologically decrease kidney function.
 The study aimed to evaluate kidney function in an elderly patient with AML after HSCT.
 Methods: The article describes a clinical case of AML in an elderly patient who underwent allogeneic HSCT.
 Results: We analyzed the dynamics of the functional state from the moment of registration of AML to +100 days after HSCT. During the entire follow-up period, we did not detect any renal dysfunction in the elderly patient. Despite the HSCT and the effects of nephrotoxic drugs in an elderly patient + 100 days after HSCT, kidney function was preserved.
 Conclusion: The described case highlights the importance of maintaining renal function in elderly patients after HSCT and long-term renal monitoring.

Insights Obtained from the Nontumorous Glandular Tissue in Patients with Endocrine Tumors.

The pathology of neoplasia tends to focus on the tumor that requires characterization, grading, and staging. However, nontumorous tissue surrounding the lesion can also provide information, particularly about pathogenetic mechanisms. In endocrine tissues, this takes the form of precursor lesions that characterize several genetic predisposition syndromes. In addition, because of the unique functional aspects of endocrine neoplasia, the nontumorous tissue provides evidence of hormone excess, with hyperplasia and/or atrophy and other involutional changes allowing the pathologist to confirm both hormone function by the tumor and the effects of medical therapies. In this article, we review the various clinically relevant features that should be assessed and reported to enhance clinical management of patients with endocrine neoplasms. For example, in thyroid there may be inflammatory thyroiditis or goiter of various etiologies; there may be C-cell hyperplasia either as a preneoplastic lesion in patients with genetic predisposition to medullary thyroid carcinoma or as a reactive phenomenon. Drug-induced changes can be seen in thyroid and adrenal cortex. In neuroendocrine tissues, the nontumorous tissues may show precursor lesions such as endocrine cell hyperplasia/dysplasia; there may be related or unrelated hyperplastic or neoplastic lesions. Some tissues, such as pituitary corticotrophs and adrenal cortex, develop changes that reflect feedback suppression by hormone excess that can serve as biomarkers of tumor functionality and provide enhanced clinicopathologic correlates.

A New Approach toward the Management of Patients with Premature Skin Aging Using the Predictor Effect

Our study aimed to develop a comprehensive approach to the management of patients with involutional skin changes, considering the predictors of premature skin aging. The study included two stages, whereby 78 women with no history of aesthetic procedures that could have affected their perceived age were examined. In the first stage, we examined factors associated with premature skin aging. In the second stage, a blind, comparative placebo-controlled study of the effectiveness of intradermal injections for the treatment of involutional skin changes was conducted. Parameters reflecting skin aging were identified. The sum of these parameters could be used to diagnose premature skin aging in patients with no history of aesthetic treatment. For other patients, we developed indicators that can be applied to determine whether there is a risk of premature skin aging. Patients with premature aging have an increased risk of adverse events, such as impaired regeneration and wound healing, postprocedural hematomas, etc. For the correction of involutional skin changes in patients with premature aging, the collagen product (Collost) had the greatest clinical efficiency and the greatest patient satisfaction. A complex product based on HA (Teosyal Redensity 1) had comparable efficiency, with slightly less patient satisfaction. The product based on native HA (Hyon 1.8%) had low efficiency in the group of patients with premature aging and high efficiency in the group of patients with normal aging.

Assessment of the immune status of women after ablative fractional laser photothermolysis procedure for the correct of involutional facial skin changes

Introduction. Ablative fractional laser photothermolysis (A-FLPh), used for rejuvenation of aging skin, is based on its controlled damage. Factors of the immune system are involved in the reparative regeneration processes triggered, which, in turn, is also subject to age-related remodeling or immunostaining. The aim of the work was to evaluate in dynamics the response of the immune system to the A-FLPh procedure performed for correction of age-associated facial skin changes. Materials and methods. The study included 25 women aged 42 to 55 years who underwent A-FLPh treatment of facial skin with an Erbium laser. The number of leukocytes, monocytes, neutrophils, lymphocytes, T-lymphocytes, T-helpers, cytotoxic T-cells, regulatory T-cells, NKT-lymphocytes, NK-lymphocytes were counted in the peripheral blood before, on the 8th and 24th after the procedure. We studied phagocytic function of neutrophils and monocytes, NBT-reducing and lysosomal activity of neutrophils; determined the amount of IgA, IgM, IgG, IL-4, IL-6, IL-8, IL-10, circulating immune complexes (CIC). Results. On the 8th day after A-FLPh, the number of neutrophils, neutrophils and monocytes phagocytosis, the number of lymphocytes, regulatory T-cells, IL-6 and IL-8 levels significantly increased; in parallel, the number of CD11b+ NK-lymphocytes, CD11b+ NKT-lymphocytes, IgA, IgG, IL-10 concentrations decreased. On the 24th day, quantitative functional indices of neutrophils, total number of lymphocytes, concentrations of IgA and IgG had no reliable difference from pre-procedure values, phagocytic parameters of monocytes, number of regulatory T-cells, IL-6 and IL-8 levels remained significantly higher, while the number of CD11b+ NK-lymphocytes, CD11b+ NKT-lymphocytes and IL-10, on the contrary, significantly lower than the initial level. Discussion. The revealed changes of systemic immunity indices after A-FLPh testify to both direct and regulatory-modulatory influence of immune factors on skin repair and remodeling after laser damage. Conclusion. The A-FLPh procedure induces a response from both cellular and humoral factors of the immune system, predominantly innate immunity.

Edema-like marrow signal intensity (ELMSI) associated with nonossifying fibroma (NOF) on MRI: an uncommon finding in a common bone lesion.

To investigate the association between nonossifying fibroma (NOF) and perilesional edema-like marrow signal intensity (ELMSI) on MRI and discuss the clinical and diagnostic implications of this finding. A retrospective search for "nonossifying fibroma" and "NOF" on knee MRI reports of patients up to 20years of age over a 5-year period was performed. A total of 77 patients (34 males, 43 females, ages 11-20) were identified, and each MRI was reviewed to evaluate for ELMSI associated with the NOF. Statistical analysis was performed to determine if there was a correlation with the presence of perilesional ELMSI and age, gender, lesion size, or signal characteristics. Twelve patients out of 77 (16%) had ELMSI associated with a NOF. Excluding patients who had additional findings of pathologic fracture (n = 2), a known potential complication of NOFs, and edema related to an adjacent osteoid osteoma (n = 1), a total of 9 patients (12%) had otherwise unexplained perilesional ELMSI. There was no statistically significant difference between patients with vs. without perilesional ELMSI with respect to age (p = 0.08), gender (p = 0.28), lesion size (p = 0.52), or appearance on fluid-sensitive sequences (p = 0.81). ELMSI can be seen about NOFs encountered around the knee joint on MRI, which may represent active healing and/or involutional change of this "do not touch" lesion in cases where no other explanation is identified.

A patient with connective tissue dysplasia at a cosmetologist's appointment: features of diagnosis and management

Patients with various manifestations of involutional skin changes often come to an appointment with a cosmetologist and a dermatologist. Among such patients, a group can be distinguished who have premature aging, or rather more pronounced signs of facial aging, in comparison with their peers. Сonnective tissue dysplasia are often found in this group of patients.
 An example of a patient with connective tissue dysplasia, with multiple organ disorders, with skin manifestations of dysplasia is presented. Tactics of managing such patients, diagnostic features and possible errors in the management of patients with connective tissue dysplasia are analyzed. Particular attention should be paid to the joint management of such patients with doctors of other specialties, respectively, the organ systems involved and recommendations for patients with connective tissue dysplasia regarding lifestyle.

Soft-Tissue Correction Method for a Sunken Eyelid.

The periocular area is one of the initial parts of the face that show signs of aging, where patients usually worry about the visual manifestations of aging, such as the sunken lower eyelid. The condition is usually caused by iatrogenic factors or involutional changes in the periocular area. This study aimed to develop and improve surgical methods to fill the sunken lower eyelids and examine their efficacy and safety. This study included 26 patients who had been treated with the musculofascial flap transposition method from the upper to the lower eyelid, under the posterior lamella. In the presented method, a deepithelized triangular musculofascial flap with a lateral feeding pedicle was transposed from the upper eyelid to the lower eyelid tear through depression. In all patients, the method achieved either a complete or a partial elimination of the defect. The proposed method to fill a defect of soft tissues in the arcus marginalis can be considered useful if upper blepharoplasty has not been performed previously and the orbicular muscle has been preserved.
