The Effects of Vasonatrin Peptide on Fat Graft Viability: An Experimental Study.

Vasonatrin peptide (VNP) is a synthetic peptide that possesses vasodilatory, natriuretic, and anti-inflammatory properties. The authors aimed to analyze the effects of VNP on fat graft survival. Twenty Sprague-Dawley rats are randomly divided into two groups of 10.

Discussion of Histopathological Findings of 954 Breast Reduction Specimens.

Objectives: Breast reduction is a frequently sought procedure by patients and one of the most commonly performed operations by plastic surgeons. Follow-up of histopathological results after reduction mammoplasty is very important. This study aimed to evaluate the histopathological results of patients undergoing bilateral reduction mammoplasty to determine the incidence of breast lesions and risk factors of high-risk breast lesions.

Salvage of the Exposed Cardiac Pacemakers With Fasciocutaneous Local Flaps.

Objectives: This study aims to investigate the efficacy of salvage of the mechanically exposed cardiac pacemakers with fasciocutaneous local flaps in elderly patients.

Methods: Between January 2014 and January 2018, ten patients (six females, four males; mean age 66.2 years) who were treated due to pacemaker exposition were retrospectively analyzed in this study.

Coexistance of Gynecomastia and Poland Syndrome: Case Report.

Coexistence of the Poland syndrome and gynecomastia is a rare condition. Poland syndrome requires soft tissue augmentation of the affected side, whereas gynecomastia necessitates reduction of the breast tissue. To provide symmetry, breast reduction and fat grafting techniques should be combined.

Requirement of the Preservation of Mental Nerve During the Transfer of Depressor Anguli Oris Composite Flap.

Objectives: Reconstruction of wide lower lip defects is still a challenging subject in terms of obtaining functional and aesthetically acceptable results. Lower lip reconstruction with depressor anguli oris muscle was first described by Tobin in 1983. Since the sensory innervation of this composite muscle flap is provided by the mental nerve, it has been advocated that the mental nerve should be preserve during flap elevation.

Posterior Arm Perforator Flap for Axillary Reconstruction After Hidradenitis Suppurativa Excision.

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory disease arising from the hair follicles in apocrine gland-rich areas. It is also one of the most common indications for axillary surgery. Reconstruction of the axillary region after such surgery must be performed meticulously due to its critical location and crucial content.

Approach to Patients with Malignant Melanoma of Unknown Primary Origin.

Objectives: Although malignant melanoma accounts for 3% of skin cancers, it is responsible for 75% of deaths associated with skin cancer. In our study, all melanoma cases diagnosed and treated at our clinic were retrospectively reviewed, and the cases of unknown primary origin among them were examined in detail in terms of diagnosis and treatment.

Methods: The patients with malignant melanoma treated at the inpatient services of our clinic between January 1991 and April 2017 were retrospectively screened in the records.

Tip Reinforcement Flap: An Original Technique for Improving Nasal Tip Support and Definition.

Background: Middle crura support deficiency and short middle crura can usually cause insufficient definition and projection of the tip and can sometimes result in a flat tip. The aim of this study was to investigate the effectiveness of a new technique involving a tip reinforcement flap to strengthen the middle crura and to achieve a well-projected and defined tip.

Methods: Twenty-nine patients who underwent primary open-approach rhinoplasty that included the use of tip reinforcement flaps were included in the study.

Comparison of venous repair results using either arterial or vein grafts in a crush-avulsion injury model.

Background/aim: Venous insufficiency after replantation or revascularization is one of the most common causes of limb loss in either the short or the long term. The aim of this study was to evaluate the results of a new technique to overcome venous insufficiency.

Materials And Methods: A crush-avulsion type of injury was formed in the femoral veins of rats of 3 separate groups.

Comparison of piezosurgery, percutaneous osteotomy, and endonasal continuous osteotomy techniques with a caprine skull model.

Background: Osteotomy is a crucial step in rhinoplasty, which can have a significant impact on the outcome. In addition to previous percutaneous (external perforating) and endonasal (internal) approaches, piezosurgery has been used in rhinoplasty practice since 2007. This experimental model was planned to compare the three osteotomy techniques.

Combination of ischemic preconditioning and postconditioning can minimise skin flap loss: experimental study.

Objectives: Ischaemic preconditioning and postconditioning, which consist of one or a series of short ischaemic events. This study aimed to determine the efficiency of post-conditioning a flap in the minimisation of flap loss after a preconditioned skin flap.

Methods: The rats were divided into five groups: sham group, control group, pre-con group, post-con group, and pre + post-con group.

Use of platelet-rich plasma solution applied with composite chondrocutaneous graft technique: an experimental study in rabbit model.

Purpose: Composite chondrocutaneous grafts have been used widely for patients with cleft lip nasal deformity, alar defects, and septal perforations; however, the graft viability can be easily compromised. The aim of the present study was to extend the safe length of the composite chondrocutaneous grafts by enhancement of angiogenesis and re-epithelialization through platelet-rich plasma (PRP) and to investigate the changes that occur when PRP is administered to the graft and the recipient site.

Materials And Methods: Composite grafts of critical sizes (1.

Human fingernail as interpositional graft material in the treatment of nasal septal perforations.

Purpose: The etiology of nasal septal perforations involves iatrogenic, traumatic, inflammatory, infectious, neoplastic, and caustic causes. To ensure successful closure, an appropriate interpositional graft material should be selected, and this graft material should be covered with healthy tissue.

Materials And Methods: The study included 18 New Zealand white rabbits weighing 2 to 2.

Severe symmetrical facial lipoatrophy in a patient with discoid lupus erythematosus.

Acquired partial lipodystrophy is a rare disorder, and it is characterized by the absence of subcutaneous fat from the face, the neck, the trunk, and the upper extremities. The etiology of acquired partial lipodystrophy includes scleroderma and discoid lupus erythematosus. Literature review reveals studies involving 10 patients until today with lipoatrophy due to or after the onset of discoid lupus erythematosus; all are female patients.

Perineoscrotal reconstruction using a medial circumflex femoral artery perforator flap.

Major scrotal defects may result from infection due to Fournier's gangrene, excision of scrotal skin diseases, traumatic avulsion of scrotal and penile skin, and genital burns. The wide spectrum of bacterial flora of the perineum, difficulty in providing immobilisation, and obtaining a natural contour of the testes make testicular cover very difficult. Various methods have been reported to cover the penoscrotal area, including skin grafting, transposing them to medial thigh skin, and use of local fasciocutaneous or musculocutaneous flaps.
