TULUA Lipoabdominoplasty: Transversal Aponeurotic Plication, No Undermining, and Unrestricted Liposuction. A Multicenter Study of 845 Cases.

BACKGROUND: TULUA (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar) is the acronym for a radically different lipoabdominoplasty, intended to add simplicity, improve vascular safety, and attain good results. Modifications are unrestricted liposuction, no flap detachment, massive transverse infraumbilical plication, umbilicus amputation, neoumbilicoplasty, diminished tension wound closure, and low transverse scar settlement. The objectives of this article are to describe the technique and analyze a multicenter experience. METHODS: Sixty-eight plastic surgeons from 10 countries provided data for a retrospective review of 845 patients. Aesthetic results were scored by each surgeon using the Salles scale and analyzed in combination with complications to identify associations between patient and surgery characteristics. RESULTS: Of the patients, 95.5 percent were female, 19.7 percent were obese, 35.6 percent had prior scars, 10.4 percent had undergone previous abdominoplasty, 6.5 percent were postbariatric, and 6.6 percent were smokers. One patient had a kidney transplant, and 16.5 percent had comorbidities. Surgery characteristics varied widely, being on average as follows: lipoaspirate, 2967 ml; resection, 1388 g; and surgical time, 3.9 hours; 46.5 percent were not hospitalized. Averaged results were 8.68 of 10 points, besides adequate positioning and proportion of scar and umbilicus, without epigastric compensatory bulging (4.97 of 6 points). Overall complications were 16.2 percent, mostly seroma (8.8 percent); vascular-related complications (i.e., necrosis, wound dehiscence, and infection) constituted 2.7 percent. There were no fatalities. The logistic regression model demonstrated that smoking and obesity duplicate the risk of complications; if age older than 60 years is added, the risk of complication increases seven to nine times. Reported indications were multiple; however, pathologic diastasis was excluded. CONCLUSION: TULUA lipoabdominoplasty is a new reproducible procedure with good quantified results and an acceptable complication rate. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Regenerate healing outcomes in unilateral mandibular distraction osteogenesis using quantitative histomorphometry.

BACKGROUND: The authors' goal was to ascertain regenerate bone-healing metrics using quantitative histomorphometry at a single consolidation period. METHODS: Rats underwent either mandibular distraction osteogenesis (n = 7) or partially reduced fractures (n = 7); their contralateral mandibles were used as controls (n = 11). External fixators were secured and unilateral osteotomies performed, followed by either mandibular distraction osteogenesis (4 days' latency, then 0.3 mm every 12 hours for 8 days; 5.1 mm) or partially reduced fractures (fixed immediately postoperatively; 2.1 mm); both groups underwent 4 weeks of consolidation. After tissue processing, bone volume/tissue volume ratio, osteoid volume/tissue volume ratio, and osteocyte count per high-power field were analyzed by means of quantitative histomorphometry. RESULTS: Contralateral mandibles had statistically greater bone volume/tissue volume ratio and osteocyte count per high-power field compared with both mandibular distraction osteogenesis and partially reduced fractures by almost 50 percent, whereas osteoid volume/tissue volume ratio was statistically greater in both mandibular distraction osteogenesis specimens and partially reduced fractures compared with contralateral mandibles. No statistical difference in bone volume/tissue volume ratio, osteoid volume/tissue volume ratio, or osteocyte count per high-power field was found between mandibular distraction osteogenesis specimens and partially reduced fractures. CONCLUSIONS: The authors' findings demonstrate significantly decreased bone quantity and maturity in mandibular distraction osteogenesis specimens and partially reduced fractures compared with contralateral mandibles using the clinically analogous protocols. If these results are extrapolated clinically, treatment strategies may require modification to ensure reliable, predictable, and improved outcomes.
