AbstractNasal profile line has central importance in forming an aesthetically balanced facial profile. Thus, rhinoplasty is a critically necessary surgery in shaping ideal profile line. For successful rhinoplasty, meticulous preoperative evaluation and proper planning should be performed before surgery. The nasal dorsum is the broadest and most prominent part of the nose; any minor imperfection is readily appreciated by an observer. Thus, dorsal augmentation is one of the most challenging areas in rhinoplasty as there is virtually no single ideal graft material and method for the nasal dorsum, which is free of aesthetic complication The surgeon should be able to discern the pattern of the abnormal nasal profile and to strategize the best possible surgical option to create a long-lasting, aesthetically pleasing dorsal line in good harmony with the overall facial profile. This study addresses our strategy to deal with various types of aesthetically unpleasant nasal profile line. The characteristics of augmentation materials and considerations in surgical technique are also addressed.

Abstract Background: To establish normal reference ranges of fetal facial profile markers, and to study their correlation with crown-rump length (CRL) during first trimester (11~13+6 weeks’ gestation) in a Han Chinese population. Methods: Ultrasonographic images of measuring fetal nuchal translucency (NT) were retrospectively selected randomly in normal pregnancies where both parents were of Han Chinese ethnicity. The facial markers included inferior facial angle (IFA), maxilla-nasion-mandible (MNM) angle, facial maxillary angle (FMA) and profile line (PL) distance. These markers were measured through ViewPoint 6 software by two experienced sonographers.Results: Three hundred and eighty fetuses were selected. The ICCs (95% CI) of intra-operator 1 reproducibility of IFA, MNM angle, FMA, PL distance were 0.944 (0.886~0.973), 0.804 (0.629~0.902), 0.834 (0.68~0.918) and 0.935 (0.868~0.969), respectively. The ICCs (95% CI) of intra-operator 2 reproducibility of IFA, MNM angle, FMA, PL distance were 0.931 (0.857~0.967), 0.809 (0.637~0.904), 0.786 (0.600~0.892) and 0.906 (0.813~0.954), respectively. The ICCs (95% CI) of inter-operator reproducibility of IFA, MNM angle, FMA, PL distance were 0.885 (0.663~0.953), 0.829 (0.672~0.915), 0.77 (0.511~0.891) and 0.844 (0.68~0.925), respectively. The average±SD of IFA, MNM angle, FMA and PL distance were 80.2°±7.25°, 4.17°±1.19°, 75.36°±5.31°, 2.78±0.54 mm, respectively. IFA and PL distance significantly decreased with CRL, while MNM angle and FMA significantly increased with CRL.Conclusion: It was feasible to measure fetal facial markers during first trimester. The normal range of each marker was obtained through large sample data, and the measurements were found to correlate with CRL.

OBJECTIVEHydrocephalus is recognized as a common disabling pediatric disease afflicting infants and children disproportionately in the developing world, where access to neurosurgical care is limited and risk of perinatal infection is high. This surgical case series describes the Project Medishare Hydrocephalus Specialty Surgery (PMHSS) program experience treating hydrocephalus in Haiti between 2008 and 2015.METHODSThe authors conducted a retrospective review of all cases involving children treated for hydrocephalus within the PMHSS program in Port-au-Prince, Haiti, from 2008 through 2015. All relevant epidemiological information of children treated were prospectively collected including relevant demographics, birth history, hydrocephalus etiology, head circumference, and operative notes. All appropriate associations and statistical tests were performed using univariate and multivariate logistic regression analyses.RESULTSAmong the 401 children treated within PMHSS, postinfectious hydrocephalus (PIH) accounted for 39.4% (n = 158) of cases based on clinical, radiographic, and endoscopic findings. The majority of children with hydrocephalus in Haiti were male (54.8%, n = 197), born in the rainy season (59.7%, n = 233), and born in a coastal/inland location (43.3%, n = 61). The most common surgical intervention was endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) (45.7%, n = 175). Multivariate logistic regression analysis yielded coastal birth location (OR 3.76, 95% CI 1.16–12.18) as a statistically significant predictor of PIH. Increasing head circumference (adjusted OR 1.06, 95% CI 0.99–1.13) demonstrated a slight trend toward significance with the incidence of PIH.CONCLUSIONSThis information will provide the foundation for future clinical and public health studies to better understand hydrocephalus in Haiti. The 39.4% prevalence of PIH falls within observed rates in Africa as does the apparently higher prevalence for those born during the rainy season. Although PIH was the most frequent etiology seen in almost all birth locations, the potential relationship with geography noted in this series will be the focus of further research in an effort to understand the link between climate and PIH in Haiti. The ultimate goal will be to develop an appropriate public health strategy to reduce the burden of PIH on the children of Haiti.
