The Rhino-Lip-Lifting: A Novel Proposal for Midface Profileplasty Performed as a Single Surgical Procedure

As facial aging occurs, aesthetic changes of the nasal tip and the senile upper lip include tip ptosis, increase in skin length, loss of vermillion height and Cupid's bow, and vertical wrinkles.Regardless of the rejuvenation procedure, the lips are not to be considered as a single anatomical entity, instead they should be placed in a strong correlation with the nose. The aim of this study is therefore to demonstrate the effectiveness of the association of primary closed rhinoplasty together with indirect subnasal lip-lifting technique.A total of 45 patients were enrolled in this study and underwent primary closed rhinoplasty with indirect subnasal lip-lifting. The result showed an overall average nasolabial angle width reduction of 10.9% and lip length shortening of 23.5%, as assessed 1 year after the surgical procedure. When comparing before and after photographs and using the Subjective Global Aesthetic Improvement Scale (sGAIS), the overall satisfaction was rated 4.4 on 5, as “much improved.”The authors show that lips should not be considered as a single anatomical entity but that they indeed must be placed in a strong correlation with the nose since a droopy nasal tip is likely to be considered unattractive and is often associated with the appearance of a long nose with covered philtrum and upper lip.Tip rotation to a normal nasolabial angle width could grant a beneficial impact on overall nose aesthetics; however, it may not fully balance the midface profile as it is the “lip position-to-incisal show” ratio that defines beauty, whereas the balance among forehead, nasal tip, upper lip, and chin is what defines the contour of harmonious profiles.This is the first patient series to show that the combination of closed rhinoplasty and indirect lip-lifting is a highly effective, safe, and reliable procedure to address profile rejuvenation.

Five-year changes in anterior segment parameters in an older population in urban southern China: the Liwan Eye Study

PurposeTo investigate the 5-year changes in static and dynamic anterior segment optical coherence tomography (AS-OCT) parameters and their predictors.MethodsThis was a prospective, population-based cohort study of people aged 50 years and older residing in the Liwan District, Guangzhou, China. Standardised AS-OCT scans were performed in November 2008 and November 2013 under dark and light conditions. Customised software was used to analyse horizontal AS-OCT images. Parameters in dark and measurements of light-to-dark changes were used for analyses.ResultsA total of 186 (71.8%) subjects underwent AS-OCT twice, 5 years apart and were included for analyses. The mean age in 2008 was 64.7±7.0 years, and 60.2% were women. The anterior chamber width (ACW) decreased from 11.74±0.44 mm in 2008 to 11.60±0.37 mm in 2013 (p=0.001). There was a trend towards a decrease in dynamic capacity (light-to-dark changes) in the anterior segment, with decreased iris thickness at 750 µm (ΔIT750), ΔACW, Δ anterior chamber area (ACA) and Δ pupil diameter at 5 years (all p<0.05). After adjusting for age and sex, the following baseline parameters were associated with a greater decrease rate in trabecular iris space area at 500 µm (TISA500) at 5 years: TISA500, IT750 and ACA in dark (p<0.001 for all).ConclusionsAnterior chamber angle width decreased and the amount of light-to-dark changes declined during 5-year follow-up. Subjects with greater height, wider angle width and thicker iris at baseline have greater angle narrowing at follow-up.

The effect of insulator geometrical profile on electric field distributions

<span>In recent years, silicone rubber (SIR) insulators are use widely on high voltage transmission lines, particularly in heavy polluted environment. The performance of SIR in highly dependent on electric field profile that may lead to other serious problem such as ageing and flashover phenomenon. In this paper, electric field and potential distribution around insulator profile were computed using finite element method approach. Insulator geometrical profile i.e. shed radius, inclination angle, width and length has been varied and analyzed. Simulation results reveal that electric field is greatest at area near to the ground and high voltage terminal. Several recommendations have been proposed on insulator profile in achieving optimized electrical performance of the insulator.</span>
