James M Economides, David H Song
Background: Despite the popularity of latissimus dorsi (LD) flap in breast reconstruction, a breast implant is often necessary to achieve sufficient volume. Prior reports describe fat grafting to the LD flap as a secondary procedure to correct contour deformities and improve volume. Our institution has instituted autologous breast reconstruction with an LD flap and immediate fat transfer (LIFT). Methods: A retrospective review of all patients undergoing the LIFT procedure was undertaken...

Background: The use of negative-pressure wound therapy (NPWT) for Fournier gangrene management is well documented; however, it is difficult to fixate GranuFoam dressings and maintain an airtight seal over the perineum area. We developed a simple method to facilitate GranuFoam fixation and improve airtight sealing. Methods: The Fournier's gangrene severity index (FGSI) score less than 9 was collected in from January 2015 to October 2016. All 13 patients underwent fasciotomy, and NPWT was applied directly on fasciotomy wounds after the debridement of infected tissue...

The objective of this study was to determine the effects of shackling and wing flapping on stress, postmortem metabolism, AMP-activated protein kinase (AMPK), and quality of broiler pectoralis major. Before slaughter, a total of 80 Arbor Acres broilers was randomly categorized into 2 replicate pens (40 broilers per pen) and each pen randomly divided into 2 groups (shackling, T; control, C). Corticosterone, creatine kinase, and lactate dehydrogenase were determined on blood plasma parameters. Pectoralis major were removed after evisceration and used for determination of energy metabolism, meat quality, and AMPK phosphorylation...

Free flaps based on static slings principles cannot provide esthetic and functional outcomes at a desired level in total or close to total lip loss. Therefore, dynamic methods have become a current issue in recent years and especially the idea of functional gracilis free muscle flap has been suggested. In this study, we present a case of a successful total lower lip repair with this flap.In a 78-year-old female patient who was diagnosed with squamous cell carcinoma involving the entire lower lip, bilateral modified radical neck dissection and full-thickness total resection with 1 cm surgical margin so as to include both commissures of the tumor were performed and then a free gracilis muscle flap was transferred from the same side...

Background : An estimated 125,711 face-lifts and 54,281 neck-lifts were performed in 2015. Regardless of the technique employed, facial and neck flap elevation carries with it anatomical risk of which any surgeon performing these procedures should be aware of. Statistics related to anterior jugular vein injury during these procedures have not been published. Objective : To define a "danger zone" that will contain both of the anterior jugular veins on the basis of anatomical landmarks to aid surgeons with planning their surgical approach during rhytidectomy in the anterior neck region...

INTRODUCTION: There are many techniques to identify vessels in perforator surgery, each with specific disadvantages. Handheld Dopplers are easy to use, but inaccurate with respect to the exact localisation of the perforator. Angio-CT is invasive, time consuming, and expensive. In contrast, duplex sonography is a reliable, easy-to-use and availabe alternative for pre-, intra-, and postoperative visualisation of vessels. Power Doppler further increases sensitivity and allows visualisation of vessels smaller than 0...

BACKGROUND: The ischial region is the site most affected by pressure sores and has the highest recurrence and complication rates compared to other affected sites. We developed a practical and safe pedicled flap for reconstruction of ischial pressure sores based on the rich available perforators from the internal pudendal artery and the surplus of skin at the infragluteal fold. METHODS: A retrospective cohort study was conducted in all patients who underwent ischial pressure ulcer reconstruction using the PIPAP flap between March 2010 and March 2017...

BACKGROUND: Anteromedial thigh flaps are far less clinically appealing than their anterolateral counterparts, and are occasionally considered as an alternative to the anterolateral thigh flap. Herein, we report the study of soft-tissue defects reconstruction in the knee using a distally based anteromedial thigh flap pedicled on the rectus femoris branch of the descending branch of the lateral circumflex femoral artery. PATIENTS AND METHODS: Between July 2008 and September 2016, a distally based anteromedial thigh flap was used to reconstruct soft-tissue defects of the knee in 5 patients (3 males, 2 females; age range at surgery 4-55 years old)...

We present a study of the hemolymph vascular system of the marbled crayfish, Procambarus fallax f. virginalis, the only crayfish species known to be parthenogenetic. To identify potential evolutionary patterns, we compared data from a total of 48 specimens of P. fallax with 22 specimens of Orconectes limosus. Visualizations (2D and 3D) were carried out using a combination of classical and modern morphological techniques. Our data were compared to the existing literature. Like all Decapoda, both P. fallax and O...

Osteoma is an uncommon benign osteogenic tumor characterized by the proliferation of compact and cancellous bone. The objective of this study was to report a case of osteoma in the basilar region of the mandible. The patient reported no pain, but the affected area was tender to touch and there was esthetic concern because of the apparent swelling. The mass measured approximately 5 cm in diameter and extended to the lingual area of the mandible. A vestibular approach was used for surgical treatment. After infiltration of a local anesthetic and vasoconstrictor, to expose the mandibular ramus, an incision was made with an electric scalpel along the external oblique ridge through the mucosa, submucosa and muscle, fascia and periosteum until the lower second molar, 3 to 5 mm inferior to the mucogingival junction...

BACKGROUND: The gastrocnemius muscle flap may be considered the first choice in many cases of soft-tissue reconstruction about the knee. Limited arc of rotation and reach of the flap as well as unsightly muscle bulk are major disadvantages and were the impetus to look for a local alternative. The aim of this study is to present a consecutive series of patients with a reconstruction about the knee involving the medial sural artery perforator flap (MSAPF). METHODS: A consecutive series of 17 cases of defect reconstructions about the knee using the MSAPF is described, with an emphasis on early postoperative complications...

INTRODUCTION: Soft tissue and bone radionecrosis are rare but serious complications may occur late after radiotherapy. CASE REPORT: We report the case of an 86-year-old woman with a history an infiltrating ductal carcinoma of the left breast, treated by total mastectomy, left axillary dissection and adjuvant radiotherapy. Eighteen years later, the first radionecrosis lesions appeared and grew progressively in a 6-month period. These lesions are deep, involving the anterior aspect of the 4th to the 6th ribs and infiltrating the chest wall to the left cardio-thoracic space communicating largely with the pericardium...

BACKGROUND: The medial triceps brachii is vascularized by the middle collateral artery and the arterial circle of the elbow. This vascularization allows a distal pedicled use to cover soft tissue defects of the elbow. We report our experience using this flap to cover traumatic and postsurgical wounds. METHODS: Patients who underwent a pedicled medial triceps brachii flap procedure between 2008 and 2015 were included. Data concerning characteristics of the patients, wound size, surgical technique, and complications were retrospectively reviewed...

REVIEW

A full-thickness fourth-degree burn to a large area of the upper extremity may require a forequarter amputation. Whereas our case describes a burn injury, forequarter amputations may more commonly be done in oncological surgery. In addition to the challenge of providing well-vascularized tissue coverage, the burn patient may also pose the complication of respiratory compromise in a systemically ill person. Fillet flaps have often been utilized as "spare part" reconstruction. Although previous forequarter amputations have been covered with free myocutanous forearm fillet flaps, we devised a rotational pedicle myocutaneous forearm fillet flap that might be less complex than a microvascular reconstruction...
