The skin is the most requested product of ratite slaughter and 'first-rate' ratite's skin has a high economic market. Ostrich hide is tanned in South Africa and sold all over the world. Besides, the ostrich meat is considered a niche production in the marketplace, thus allowing for another pro t for the ostrich breeding. Theorical analysis of skinning process has been carried out, and an automatic measurement system has been designed to record the drawing-force on the animal's body during skinning tests. The aim of this study was to indentify the best animal position and provide values of drawing-force in order to design a speci c machine for ostrich skinning...

INTRODUCTION: The clinical anatomy of the infrapatellar branch of the saphenous nerve (IPBSN) is of particular importance during operations in the area of the knee, especially when material for anterior cruciate ligament reconstruction is harvested. The nerve can easily be injured during the harvesting procedure, leading to postoperative complications that reduce quality of life. Three different skin incisions are commonly used during hamstring tendon harvesting: horizontal, vertical, and oblique...

EDITORIAL
B A Ginsberg
Given the complexities of the transitioning process, transgender individuals may face unique dermatologic needs in addition to routine care. Exogenous hormones affect hair and sebum production, gender-confirming surgeries often require dermatologic pre- and postoperative interventions, and postoperative anatomy may show unique presentations of routine skin conditions. Aesthetic techniques that are often used for rejuvenation may have a role in facial feminization and masculinization and unfortunately are too frequently performed by nonmedical personnel with negative consequences...

Postburn lip deformities pose a significant set of challenges to reconstructive burn surgeons because of the complex anatomy, diverse functions, and specialized nature of the lip tissues. There has been a paucity of literature on restoration of the vermillion to date. The authors report on two patients who suffered burn injuries resulting in significant lip deformities who underwent a novel method of vermillion reconstruction with a full thickness anal verge skin graft. Both patients tolerated the procedure well without complications...

OBJECTIVES: For the purpose of simulating thoracoscopic surgery, we have conducted stepwise development of a life-like chest model including thorax and intrathoracic organs. METHODS: First, CT data of the human chest were obtained. First-generation model: based on the CT data, each component of the chest was made from a 3D printer. A hard resin was used for the bony thorax and a rubber-like resin for the vessels and bronchi. Lung parenchyma, muscles and skin were not created...

With an eye on the sequence of two Indian papers concurrently published in Diabetes Therapy, this paper analyzes skin differences among races and points to a lack of organized structured education sessions as the main cause of the high prevalence of lipodystrophy (LD) and consequent poor metabolic control. Only half of all insulin-treated patients reach their therapeutic targets worldwide. The factors involved in this are manifold, including the choice of overlong and repeatedly reused needles, as well as a failure to systematically rotate injection sites, all of which lead to skin LD...

BACKGROUND: Pre-operative spine level localization by palpation of anatomical landmarks (ribs, spinous processes) in posterior approaches for surgeries from T4 to L2 is often inaccurate. This can lead to ineffective utilization of procedural time, increased radiation dose, potentially longer skin incision and wrong level surgery. Factors affecting topographical accuracy includes body mass index (BMI) of the patient, congenital or acquired deformity and knowledge of topographical anatomy...

Hidehiro Yamamoto, Masayoshi Okada
We describe a new technique of performing sympathectomy with a new device. A single skin incision 3 mm long was made in the armpit. The device enables complete resection of the sympathetic segment through a single skin incision, whereas sympathectomy is limited by the use of the conventional needle technique. Even if sympathetic nerves and blood vessels were overlapping, separation of the two organs was performed safely. This device increases the possibility of planning surgical procedures for patients with difficult anatomies...

We are no longer entangled in the anatomical resetting of the labial-nasal muscle itself, but the sight to the muscle fiber level, to study the relationship between the muscle fiber force line and the labial-nasal shape. In the past ten years, we focused on the lip of nasal muscle fiber anatomy, imageology and biomechanics, carried out a series of research works, realized the three-dimensional (3D) visualization of small labial-nasal muscle fiber, established configuration models of normal and cleft lip with nasal muscle fibers, and put forward the hypothesis of naso-labial muscle tension band...

Eyelid malignancies represent between 5% and 10% of all skin cancers. Basal cell carcinoma is the most common, followed by squamous cell carcinoma, sebaceous cell carcinoma, Merkel cell carcinoma, and melanoma. The gold standard treatment for periocular epithelial malignancies is surgical excision. Given the constraints of the anatomy and function of the eyelids, excision with negative margins and reconstruction can be challenging. In cases of significant tissue invasion or metastasis, complete tumor removal may not be possible...

OBJECTIVES: Existing fixation methods of automatic speaking valves (ASVs) suffer from shortcomings which partly are the result of insufficient conformity of the intratracheal fixation method's shape to the tracheostoma anatomy. However, quantitative data are lacking and will be helpful to analyse solutions for airtight fixation. This article provides such data. PATIENTS AND METHODS: The tracheostoma morphology was measured in computerized tomography scans of 20 laryngectomized patients...

Ramsay-Hunt syndrome (RHS) is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus (VZV) infection occurs in the geniculate ganglion. Major clinical findings are peripheral facial nerve palsy accompanied by ipsilateral ear pain and erythematous vesicular rash on the external ear (herpes zoster oticus) and in the mouth. Thus, diagnosis of RHS is usually clinical. However, auricular herpetic eruption is not always present, making diagnosis more difficult. This report describes a case of RHS with left facial palsy without skin lesions in 60-year-old woman...

The authors performed cadaveric dissections to investigate the existence of an anatomical structure creating and maintaining the cervical mental angle, aiming to understand the anatomical bases of the cervico-mental angle and its modifications over time. Six fresh cadaver dissections were performed; four were done in the Caen University anatomy laboratory one in Paris XV University and one in the Coventry University hospital, England. At the end of this investigation, the authors were able to demonstrate the existence of an anatomical structure in the neck, the cervico-mental angle suspensory ligament...

Xiaofei Tian, Jun Xiao, Tianwu Li, Wei Chen, Qiu Lin, Harvey Chim
PURPOSE: Staged separation of 3- and 4-finger syndactyly is commonly performed owing to concerns about vascular supply to the central digit and availability of flap skin. We performed single-stage separation of patients with incomplete syndactyly of multiple digits with adjacent contiguous dorsal gullwing flaps and avoided skin grafts in the majority of cases. METHODS: Seventy-four webs of 31 patients with more than 2-finger incomplete syndactyly were included. Median age at surgical separation was 12 months (range, 5-123 months)...

REVIEW
Matthew Brown, Kevin C Chung
Postburn contractures are a common occurrence after severe burn injuries. It is important to understand the pathologic condition and anatomy of specific postburn deformities in order to provide comprehensive surgical care. Postburn contractures can result in a flexion contracture, boutonniere deformity, burn syndactyly, metacarpophalangeal extension contracture, wrist contracture, or claw hand. A patient evaluation is performed before proceeding to the operating room. Surgery sequences require proper incision design, release of the skin, and deeper contracted structures and coverage with an appropriate flap or graft...

Zygomaticomaxillary complex (ZMC) fracture is a common type of maxillofacial fracture. In addition to facial depression and diplopia, paresthesia of the lower eyelid, malar regions, nose skin, upper lip skin, and mucous membranes occurs because of infraorbital nerve injury. This article reviewed the anatomy, diagnosis, assessment, treatment, and prognosis of ZMC fracture-related infraorbital nerve injury.
