The fate of grafted lipoaspirates was affected by water-jet force. With the assistance of water-jet force during the harvesting procedure, the authors could obtain more viable lipoaspirates and achieve better fat survival.

BackgroundThe dual-plane technique has been widely used in augmentation mammaplasty procedures. However, there are some concerns about aesthetic contour maintenance for long time after muscle releasing. This study aims to track and analyze breast dynamic morphological changes after dual-plane breast augmentation with three-dimensional (3D) scanning technique.MethodsThirteen dual-plane anatomic implant augmentation patients underwent 3D scanning preoperatively (pre-OP) and postoperatively in four time points (1 month: post-1M, 3 months: post-3M, 6 months: post-6M and 12 months: post-12M). The linear distance, breast projection, nipple position, breast volume and breast surface area were measured and analyzed on the 3D models over time.ResultsCompared with post-12M, no significant differences were found in distances of nipple to midline, nipple to inframammary fold and sternal notch to the level of inframammary fold after 6 months in both straight-line distance and its projection on surface. The distances between sternal notch and nipple had no significant difference after post-1M. Breast volume changes had no significant difference after post-3M. The volume and area percentage of upper pole decreased while the lower pole’s increased gradually. The surface showed no significant changes after post-1M. The changes of breast projection had no significance after post-1M either. The nipple moved 1.0±0.6 cm laterally(X axis), 0.6±0.7 cm upward(Y axis) and 2.3±1.1 cm anteriorly (Z axis) at post-12M, and the differences were not significant after post-1M.Conclusions3D scanning technique provides an objective and effective way to evaluate breast morphological changes after augmentation mammaplasty over time. Dual-plane augmentation optimizes breast shape especially in the lower pole and maintains stable aesthetic outcome during the 12 months follow-up. Most of the contour changes and the interadaptation with the implant have completed 6 months after operation. Therefore, 6 months could be chosen as a relatively stable observing period in the assessment of postoperative outcomes of dual-plane breast augmentation.

Congenital bifid tongue is a rare malformation, which is usually present in association with other oral findings such as cleft palate and tongue mass. The authors present a rare case of congenital bifid tongue together with cleft palate, labial-buccal frenulum deformity, absence of lingual frenulum, and 3 hamartomas in the oral cavity. The authors excised oral hamartomas and repaired the palate and tongue with satisfactory results.

Background Extramammary Paget’s disease (EMPD) is an intraepithelial adenocarcinoma. The chronic relapsing clinical course and unbearable clinical symptoms of extramammary Paget’s disease usually result in a markedly diminished quality of life. No national data are available on descriptive epidemiology of EMPD in China, the most populous country over the world. This population-based study aimed to estimate the prevalence and associated sex and age patterns of EMPD in China. Methods This study was conducted using data from China’s Urban Employee Basic Medical Insurance and Urban Resident Basic Medical Insurance, covering approximately 0.43 billion Chinese urban residents in 2016. Patients with EMPD were identified based on the diagnostic names and codes in claim data. Results A total of 53 males and 31 females with EMPD were found. The crude prevalence in 2016 was 0.04 per 100,000 population [95% confidence interval (CI) 0.02–0.06], ranging from 0.01 (95% CI 0.00–0.02) in North or Northeast China to 0.08 (95% CI 0.03–0.16) in Southwest China. The rate was higher in males (0.05, 95% CI 0.03–0.08) compared with females (0.03, 95% CI 0.02–0.05). The mean age of patients was 65.87 (standard deviation: 14.21) years, with the peak prevalence appeared in patients aged 70–79 (0.28, 95% CI 0.16–0.42). Conclusions The prevalence of EMPD was markedly lower than those in the United States and Europe, and varied across regions in China. Chinese patients were much younger, with significant male predominance. Further studies are warranted to examine potential pathophysiologic mechanism.
