The effect of reduction of the peripheral fat content by liposuction-assisted lipectomy (SAL) on serum leptin levels in the postoperative period: a prospective study.

The purpose of this study was to investigate the relationship between a decrease in the peripheral fat content by suction-assisted lipectomy (SAL) and serum leptin levels. Twenty-two healthy females who underwent SAL for aesthetic reasons participated in the study. The data included height, weight, dietary habits, and leptin levels before surgery and at 1 and 6 weeks postoperatively. The aspirate ranged between 1000 and 6000 ml, with an average of 2700 ml. Thirteen patients with an aspirate of over 2700 ml all experienced an immediate postoperative decrease in appetite which returned gradually by 12 to 17 days postoperatively. They lost an average of 7% of the total body weight at 6 weeks. The leptin levels 1 week postoperatively were significantly lower than the preoperative levels (p < 0.01); at 6 weeks the decrease in leptin level was not statistically significant. In conclusion, a reduction of the peripheral fat content of more than 2700 ml by SAL has an immediate effect on leptin levels that lasts at least 1 week and correlates with voluntary changes in energy intake.

Mandibular distraction osteogenesis in very young patients to correct airway obstruction.

The purpose of this study was to measure changes in the airway cross-sectional area of pediatric patients with micrognathia and obstructive airway symptoms after treatment by mandibular distraction. The measurements obtained were correlated with the clinical outcomes.Ten patients, ranging in age from 3 months to 8 years, underwent measurement and distraction. Eight patients were under 30 months of age. Six were diagnosed with Pierre Robin sequence, two with Treacher Collins syndrome, and two with Nager syndrome. All patients had retrognathia of greater than 8 mm and obstructive airway symptoms while awake that had resulted in tracheostomy (3), repeated apnea monitor triggering (5), or abnormal sleep study (2). Cephalometric analysis was performed pretreatment and posttreatment by distraction. The effective airway space was defined with the following boundaries: a horizontal line from the tip of the odontoid to the velum, the uvula tip to the tongue base along the shortest line, the tongue base down to the base of the epiglottis, and the horizontal line to the posterior pharynx. These lines were traced for each cephalogram, the outline was digitized, and the area was calculated by computer. An analysis of the square area change was done by paired t test. The range of distraction was 8 to 22 mm; the mean effective airway increase was 67.5 percent, with a range of 26 to 120 percent. Measurable airway increase occurred in all patients who underwent distraction, and all patients showed clinical improvement. Six patients with Pierre Robin sequence became asymptomatic, with normal sleep, feeding, and weight gain. Two patients with Nager syndrome and tracheostomies were decannulated and were asymptomatic postdistraction. One patient with Treacher Collins syndrome without tracheostomy became asymptomatic after mandibular distraction; one patient failed to distract because of premature consolidation and continued to require a cannula. Mandibular distraction seems to provide a consistent change in tongue base position that improves obstructive airway symptoms by increasing measured effective airway space. The potential for mandibular distraction exceeds the simple correction of malocclusion also by eliminating soft-tissue obstruction of the micrognathic airway. Airway improvement is independent of the syndrome diagnosed. Mandibular distraction osteogenesis may be useful to avoid or decannulate existing tracheostomy in infants with micrognathia.

Secondary alveolar bone grafting using milled cranial bone graft: a retrospective study of a consecutive series of 100 patients.

OBJECTIVE: The purpose of this study was to evaluate the outcome of secondary bone grafting of alveolar clefts using milled cranial bone graft. PATIENTS: The study included a consecutive series of 100 patients who were operated on between 1986 and 1995 by a single senior surgeon. MEASUREMENTS: The patients were divided into four groups; (1) unilateral alveolar cleft or (2) bilateral alveolar cleft, (3) before eruption of the canine teeth or (4) after eruption. Follow-up ranged from a minimum of 12 months to 10 years, and evaluation included a physical examination, medical photography, orthodontic reports, and a panorex X-ray and/or a three-dimensional computed tomography scan of the maxilla produced using Denta-scan software. Patient outcomes were judged to be good, acceptable, or poor. Patients who developed any fistula or required regrafting were defined as poor outcomes. RESULTS: The combined good and acceptable outcomes represented 83% of the entire consecutive series. These two groups were defined as successful outcomes. In patients with unilateral and bilateral clefts who were under 12 years old, the success rate was 90% and 88%, respectively. In patients grafted following full canine eruption (>12 years old), success rate decreased to 83% in patients with unilateral and 66% in bilateral clefts, respectively. CONCLUSIONS: Our results support the use of milled cranial bone graft, which produces a stable closure of the alveolar cleft with good contour and support for adjacent tooth eruption. Our data further support the conclusion by others that outcomes of early secondary grafting are superior to delayed grafting. The experience presented here, including the success rate, ease of harvesting, and minimal morbidity, makes the cranium our preferred donor site for alveolar cleft grafting.

Frontofacial osteotomies, advancement, and remodeling by distraction: an extended application of the technique.

The purpose of this clinical report is to present the distraction technique for advancement of the frontofacial skeleton as a unit. Our 14-year-old patient was diagnosed with Carpenter's syndrome and kleblattschädel deformity at birth. At other centers the patient underwent corrective surgeries, including repeated fronto-orbital advancement in an attempt to correct the residual deformity. This has resulted in bony malunion and recurrent deformity, and it has left the patient with no available donor sites for harvesting of bone graft. The patient had class III malocclusion, severe midfacial and frontal deficiency, and relative turricephaly. We performed frontofacial osteotomies and placement of the distraction devices. Distraction of 20 mm was accomplished, correcting the exophthalmos and midface retrusion and producing class I dental occlusion. We conclude that distraction is an optional surgical method that can be applied in selected cases for advancement of the entire frontofacial skeleton.

Terrorist bombing with a 'Molotov cocktail' inside travelling cars: an old weapon for a new burn syndrome?

The 'Molotov cocktail' terrorist weapon which is thrown into a travelling car has given a new type of injury to people who sustain massive smoke inhalation together with disfiguring burns of face, thighs, hands and chest, and post-traumatic psychological disorder. The combination of petrol ignition with the synthetic fumes inside the care is a unique occurrence with a high morbidity and mortality which is difficult to treat and to manage. We propose to show that the combination of all the above components can be defined as the 'Molotov cocktail' burn syndrome.

Nasal tampon packing in rhinoplasty: a simple and safe method of hemostasis.
