Jowl fat

Bahman Guyuron, Nazilla S Seyed Forootan, Kris Katira
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: 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 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...

Current concepts of facial aging propose that volume losses of bone and fat in specific compartmentalized areas are the primary and the most important causes of the characteristic changes seen in the aging face. The authors propose that the use of Radiesse in the supra-periosteal space of the temple, zygomatic arch, anterior cheek, pyriform aperture, and pre-jowl sulcus most effectively and most efficiently corrects these volume losses, and therefore best helps to restore a youthful appearance. Placement of filler directly on bone produces a lifting effect on all of the overlying tissues as a single unit which the authors term "composite volumization"...

A total of 160 finishing pigs (PIC 327 × 1050; initially 45.6 kg) were used in an 84-d experiment to evaluate the effects of dietary fat source and feeding duration on growth performance, carcass characteristics, and carcass fat quality. There were 2 pigs per pen with 8 pens per treatment. The 10 dietary treatments were a corn-soybean meal control diet with no added fat and a 3 × 3 factorial with main effects of fat source (4% tallow, 4% soybean oil, or a blend of 2% tallow and 2% soybean oil) and feeding duration (d 0 to 42, 42 to 84, or 0 to 84)...

BACKGROUND: The authors believe that open access to the submental region, platysmaplasty, and wide skin undermining provide the most long-lasting results in neck rejuvenation, and sought to evaluate this hypothesis by reviewing their neck-lift patients. METHODS: The authors performed a retrospective chart review of their experience with neck-lift procedures and patients who underwent a secondary procedure. Patient age, sex, initial technique, visible neck deformities, and reasons for revision were assessed...

BACKGROUND: Fusion zones between superficial fascia and deep fascia have been recognized by surgical anatomists since 1938. Anatomical dissection performed by the author suggested that additional superficial fascia fusion zones exist. OBJECTIVES: A study was performed to evaluate and define fusion zones between the superficial and the deep fascia. METHODS: Dissection of fresh and minimally preserved cadavers was performed using the accepted technique for defining anatomic spaces: dye injection combined with cross-sectional anatomical dissection...

BACKGROUND: Patients often seek help to redress aging that affects various regions of the face (subunits). The purpose of this study was to determine how aging of different facial subunits impacts perception of age, attractiveness, and tiredness. METHOD: Frontal and lateral view facial photographs of a middle-aged woman were modified using imaging software to independently age different facial features. Sixty-six subjects were administered with a questionnaire, and presented with a baseline unmodified picture and others containing different individual or grouped aging of facial subunits...
