Successful minimally invasive repair of pectus excavatum relies on a pectus bar that closely conforms to the desired shape of the sternum and ribs to produce optimal elevation and remodeling. However, the present method of empirical intraoperative bar shaping is tedious and risks trauma to surrounding structures. To overcome this, we devised a technique using a life-sized computed tomography (CT) printout of the patient’s chest wall to guide preoperative bar bending.

A 5-cm-wide polymethylmethacrylate block placed on the sternum as the patient underwent chest CT was used as a marker to guide scaling of an axial screenshot of the patient’s chest to life-size. This life-size image was printed and the planned correction of the patient’s chest wall was traced onto it. The pectus bar was bent according to this template. Patient demographics, Haller index, surgical indications, operative technique, complications, aesthetic and functional improvements, and overall satisfaction were assessed.

Thirty patients (4ic, functional, and overall outcomes.

This technique of CT-guided preoperative pectus bar shaping is straightforward, eliminates the need for intraoperative revisions to bar shape, and achieves effective correction of the pectus excavatum deformity. All patients were satisfied with the aesthetic, functional, and overall outcomes.

Mandibular distraction osteogenesis (MDO) effectively treats tongue-based airway obstruction (TBAO) in micrognathic patients with Robin Sequence. Mandibular distraction osteogenesis may also address TBAO in certain nonmicrognathic patients who have severe obstructive apnea, although there is no current literature to guide MDO use in these atypical patients. This study describes outcomes of MDO in a series of patients with TBAO without micrognathia.

Patients who underwent MDO for TBAO from 2013-20 were reviewed, and patients with micrognathia were excluded. Study subjects received baseline/follow up polysomnography. Polysomnography variables, including Obstructive Apnea Hypopnea Index, oxyhemoglobin saturation nadir (SpO2 nadir), percent sleep time end tidal CO2 greater than 50 mm Hg (%ETCO2 > 50), and respiratory-related arousals were compared before and after MDO. Demographics, syndromic/cleft palate status, airway anomalies, respiratory support, and feeding outcomes were collected.

One hundred and for MDO and characterize outcomes of unique patient populations.

Breast reduction is one of the most common procedures performed by plastic surgeons worldwide. Despite that several techniques have been proposed for management of ptotic or hypertrophic breasts, most of them often deal with too large breast bases, poor breast projection, persistent “dog ears,” and a certain percentage of bottoming out. Lower-pole shaping of the breast remains one of the challenge of vertical mammoplasty.

The authors report their 5-year-long experience with a modification of the vertical scar technique, the “arrow flap,” in which they harvest a double lateral glandular and cutaneous flap, to tighten and better shape the base of the breast and to improve the breast projection with a “double-bra” effect. From April 2015 to February 2019, 75 patients with moderate to severe macromastia/breast ptosis underwent bilateral reduction mammoplasty.

Postoperative outcomes showed an overall satisfactory results and low incidence of complications. Two patients presented with an asymmetry between thevertical mammaplasty both for mastopexy and breast reduction, even in cases of severe macromastia.

Impaired wound healing is responsible for significant morbidity and mortality worldwide. It is necessary to find a stable, efficient, and safe method to promote soft tissue wound healing. Fat grafting has become increasingly popular in contouring procedures. However, more recently, there has been an emphasis on its regenerative potential. click here In this study, we established the wound healing model using nude mice. Hematoxylin and eosin and Masson stainings were performed to assess the effect of chyloid fat on the histology of wound healing. A laser Doppler perfusion imager was used to evaluate the blood perfusion of wounds. Immunohistochemistry was carried out to detect the expression of CD31 in wound tissues. The results suggested that after treatment with granule fat or chyloid fat, wound healing was accelerated and blood perfusion was promoted. In addition, granule fat or chyloid fat treatment promoted the angiogenesis of the wound. In addition, we evaluated the amount of adipose-derived mesenchymal stem cellsto detect the expression of CD31 in wound tissues. The results suggested that after treatment with granule fat or chyloid fat, wound healing was accelerated and blood perfusion was promoted. In addition, granule fat or chyloid fat treatment promoted the angiogenesis of the wound. In addition, we evaluated the amount of adipose-derived mesenchymal stem cells in chyloid fat and granule fat. It was found that chyloid fat contained more adipose-derived mesenchymal stem cells than granule fat did. In conclusion, we proved that chyloid fat could significantly accelerate the wound healing process via promoting angiogenesis. The adipose-derived mesenchymal stem cell plays a critical role in this effect of chyloid fat.In home caregivers of patients with percutaneous endoscopic gastrostomy face physical, social, and psychological problems. The results of qualitative studies play a key role in determining in home caregivers’ percutaneous endoscopic gastrostomy-related problems, attitudes, views, and experiences. The aim of this review was to survey the literature to assess the problems faced by in home caregivers of percutaneous endoscopic gastrostomy patients and identify solutions to these problems. PubMed, Cochrane, and Web of Science databases were screened using the key words qualitative research, percutaneous endoscopic gastrostomy, enteral nutrition, and mixed method for relevant articles published between 1945 and November 2019. The literature search yielded 446 scholarly articles. Their titles and abstracts were screened for possible inclusion in this review. Fifteen articles that met the inclusion criteria were included in the study. The quality of the included qualitative articles were assessed using the Critical Appraisal Skills Programme Qualitative Research Checklist, whereas mixed-methods articles were assessed using the Mixed Methods Appraisal Tool.
