Jowl fat

BACKGROUND: Volume loss and volume descent are complementary aspects of facial aging, although the respective contribution of each is unclear. OBJECTIVES: The aim of this study was to quantify in 3 dimensions the effects of gravity on the midface in both upright and supine positions in an older and a younger group of patients. METHODS: A prospective study was undertaken of 53 female patients who had not undergone treatment with dermal fillers or facial cosmetic surgery...

BACKGROUND: Masculinization of the face is a common finding in facelift patients. It is attributed to deflation and decent of the midface-jowls coupled with skin laxity. Fullness is evident lateral to the jowl in a small percentage due to prominent buccal fat pad (BFP). OBJECTIVES: The authors sought to examine the anatomy of the BFP, triangulate the prominent BFP with surgical landmarks, and describe an external approach to excise the BFP during facelift surgery...

Fat accumulation, skin laxity, and muscle contraction cause aging cervical fullness. Combining botulinum toxin to treat muscle contraction, and technique-oriented microfocused ultrasound for skin laxity, can improve cervical fullness without requiring lipolysis. Gel-assisted depth adjustment (GADA) is a depth-targeting, image-guided approach using an appropriate gel volume to precisely heat tissue layers during real-time visualization. METHODS: A 41-year-old woman presented with moderate submental neck fullness and saggy cheeks...

BACKGROUND: Jowl fat overhang can reduce jawline definition. The most common treatment to reduce jowl fat is liposuction. ATX-101 (deoxycholic acid injection), a minimally invasive treatment approved for submental fat reduction, may also be an effective treatment for jowl fat. The current study evaluated the efficacy and safety of ATX-101 treatment for reducing jowl fat. METHODS: In this prospective single-site study, 66 adults were treated for excess jowl fat with ATX-101 (area-adjusted dose: 2 mg/cm)...

Facial appearance is critical to physical attractiveness, and maintaining a youthful face and neck is a major motivation for individuals seeking facial cosmetic procedures. A strong mandibular border without prominent jowls is one sign of a youthful face as jowling occurs with age, contributing to squaring of the face and loss of jawline definition. Excess jowl fat has traditionally been reduced with surgical liposuction when jowling is caused by fat flow across the mandible. The approval of ATX-101 (deoxycholic acid injection) for submental fat reduction provides a minimally invasive technique that may also be suitable for jowl fat reduction...

BACKGROUND: Important differences in facial anatomy and how faces age must be considered when performing facelifts in Asian populations. Few facelift methods are specifically designed for Asian patients. OBJECTIVE: This study evaluated the efficacy of lateral superficial muscular aponeurotic system (SMAS)-stacking/SMAS-ectomy with orbicularis-malar fat repositioning. MATERIALS AND METHODS: Between February 2013 and December 2016, 62 women underwent the evaluated technique and completed the follow-up (15 months, ranging from 3 to 38...

BACKGROUND: Skin tissue dielectric constant (TDC) measurements at a frequency of 300 MHz are used to assess skin properties in many conditions. Impacts of patient obesity on these values are unknown, and its quantitative assessment was the goal of this research. MATERIALS AND METHODS: Women in a weight loss program (N = 32) had TDC measured on forearm, biceps, neck, jowl, and submental regions along with measurements of total body fat (TBF), water (TBW), intracellular water (ICW), and extracellular water (ECW) via multi-frequency bioimpedance...

The extended superficial musculoaponeurotic system (SMAS) facelift targets the 2 cardinal signs of facial aging: (1) descent of the malar fat resulting in deepening of the nasolabial folds as well as accentuation of the palpebral malar groove and tear trough deformity; (2) formation of jowls, which also obscure the definition of the lower mandibular border. In this article the authors describe the concepts behind the extended SMAS operation, importantly the extent of skin dissection and SMAS elevation. They present a brief history of the operation and landmark papers and supplement with fresh cadaver dissections...

BACKGROUND: The study proposes a novel protocol for targeting the jowls using deoxycholic acid (DCA) injections, with emphasis on safety and feasibility of the procedure. METHODS: This prospective study was conducted at a cosmetic practice between June 2016 and May 2017. Twelve consecutive patients seeking reduction/improvement in mild/moderate jowl fat were injected with DCA subcutaneously in a predefined circular area 1.0 cm above the mandibular border. Treatment response was assessed using physician-evaluated Global Aesthetic Improvement Scale (GAIS) and Subject GAIS...

BACKGROUND: Super-high superficial musculoaponeurotic system (SMAS) suspension and tailor tack plication are powerful facelift tools used in cases of primary facial rhytidectomy. TECHNIQUE: Thorough pre-operative patient screening and counseling are completed in an outpatient cosmetic surgery center. A super-high SMAS flap is developed by undermining and incising along a line extending from the tragus to lateral canthus and dissecting the SMAS sufficiently to induce movement of the lateral nose and the oral commissure with traction on the SMAS...

BACKGROUND: To investigate the layered anatomy of the jawline and to provide anatomic background for the formation of the labiomandibular sulcus, the jowl deformity, and the "double-chin" for safe and effective minimally invasive procedures. MATERIALS AND METHODS: Seventy-two fresh-frozen human cephalic cadavers (32 males, 40 females; mean age 75.2 ± 10.9 years, BMI 24.2 ± 6.6 kg/m2 , 99% Caucasian ethnicity) were investigated by layer-by-layer anatomical dissection...

Background: The appearance of a youthful neck is lost with age causing excessive skin laxity, a loss of subcutaneous fat, prominence of platysmal banding, and jowling. In view of the success obtained with laser treatment for neck rejuvenation, the authors have recently taken an algorithmic approach to developing a 7-category classification system of the aging conditions throughout the anatomic spectrum of three areas: skin, fat, and muscle. This system will correlate with specific treatment options...

Two, 120-d, experiments were conducted to determine the effects of standardized ileal digestible (SID) lysine (Lys), added Cu (tribasic copper chloride, Intellibond C; Micronutrients, Inc., Indianapolis, IN), and duration of Cu supplementation on growth performance, carcass characteristics, and fat quality in finishing pigs. In Exp. 1, 1,248 pigs (PIC 337 × 1050; initially 29.0 kg) were allotted to one of six dietary treatments, balanced on average pen weight in a randomized complete-block design with 26 pigs per pen and eight replications per treatment...

BACKGROUND: The superficial (subcutaneous) facial fat compartments contribute to the signs of facial aging, but a comprehensive anatomical description of their location and their functional behavior during the application of soft-tissue fillers remains elusive. METHODS: The authors investigated 30 fresh frozen cephalic specimens from 13 male and 17 female Caucasian body donors (age, 78.3 ± 14.2 years; body mass index, 23.1 ± 5.3 kg/m(2)). Upright-position, contrast-enhanced computed tomographic scanning, and additional magnetic resonance imaging were performed...

Two experiments were conducted to determine the duration of high-fiber ingredient removal from finishing pig diets before marketing to restore carcass yield and carcass fat iodine value (IV), similar to pigs continuously fed a corn-soybean meal diet. In experiment 1, 288 pigs (initially 38.4 ± 0.3 kg body weight [BW]) were used in an 88-d study and fed either a low-fiber corn-soybean meal diet from day 0 to 88 or a high-fiber diet containing 30% corn distillers dried grains with solubles and 19% wheat middlings until day 20, 15, 10, 5, or 0 before slaughter and switched to the low-fiber corn-soybean meal diet thereafter...

Patients with thick skin typically present with a redundant, baggy, lax skin envelope together with prominent nasolabial folds, jowls, and a heavy neck. Durable and natural-appearing rejuvenation is not possible unless the deformities are addressed adequately and harmoniously in these patients. Traditional superficial musculoaponeurotic system techniques do not include surgical release of the zygomatic cutaneous ligaments and repositioning of descendent malar fat pad, and may lead to an unbalanced, unnatural appearance and the lateral sweep phenomenon...

Supported by recent literature on the signs of aging of the middle and lower face, our clinical research has documented a loss of volume of the deep structural components of the central face and a progressive descent of the nasolabial fat and the jowl fat, leading to facial fragmentation. The signs that appear around the age of 45 to 50 years are well targeted by the mini-invasive technique described here. We focused on refitting the jowl fat and the nasolabial fat associated with cutaneous tightening. The use of absorbable barbed sutures (Quill) led to significant improvements, enabling the fitting of fat on fat...

Our objectives were to investigate fatty acid composition variation amongst adipose tissue sites, breed effects on fat quality, and the relationship of pork fat quality to fresh pork quality. Barrows and gilts (n = 347) of five purebred and one commercial crossbred line were fed commercial swine diets with DDGS inclusion at 30% (as fed) from 31.8 kg body weight until 30-d prior to harvest at 111.4 kg. Immediately after harvest, hot carcass weight was determined, adipose tissue was collected from the back, belly, and jowl, and meat samples were taken from the longissimus muscle for evaluation of pork quality...

Feeding cake with remaining oil contributes dietary energy (fat) in addition to protein (AA) and may provide an opportunity to enrich the n-3 fatty acid content of pork. Information regarding safety, growth performance, and efficacy of feeding camelina cake to pigs is limited. We therefore evaluated the effects of camelina cake inclusion in pig nursery diets. In total, 192 pigs (9.4 kg BW) were randomly allocated by sex to 48 pens, 2 heavy and 2 light pigs per pen. Pigs were fed 1 of 4 wheat-based diets including camelina cake (0%, 6%, 12%, or 18%; variety Celine) replacing soybean meal for 4 wk...

BACKGROUND: The purpose of this study is to report our experience using radiofrequency-assisted liposuction (RFAL) for neck and face contouring. This article details the operative technique, selection, complications, third-party surgeon appraisal, and patient satisfaction survey. METHODS: From November 2009 to November 2013, 55 patients who underwent RFAL treatment were enrolled in the study. Postoperative patient satisfaction surveys were conducted, and 2 independent plastic surgeons evaluated contour and skin quality with randomized preoperative and postoperative photographs at 6 months postoperatively...
