ABSTRACT
Objective@#The purpose of this study is to analyze the nasal morphological characteristics in Chinese adult, of Han nationality, by the measurements in sagittal plan and the proportionality between nose and facial structures, in order to provide aesthetic references for rhinoplasty, and individual surgical planning.@*Methods@#During 2017 November to December, 258 healthy Han Youth volunteers were included. Three-dimensional (3D) models of the facial characteristic information were collected using Artec 3D scanner, by standardized procedures. The nasal and facial distances and angulations were measured, based on predesigned facial landmarks. Thereafter, the proportions of above measurements were calculated.@*Results@#There was no significant difference between genders in absolute prominence. As for relative prominence, male nose is more prominent, resulted in a more stereoscopic facial profile. The nasal basal plane of both male and female, was more anterior than the infraorbital points, with 7% of the absolute degree of the infraorbital points. The range of the angle between the nasal basal plane and coronal plane was 2-4 degrees.@*Conclusions@#This study sets a database for the external nasal characteristics of the young adult in Chinese Han nationality, which could provide quantitative references for preoperative evaluation and individually surgical planning.
ABSTRACT
Objective To explore the treatment characteristics and effect of hip fracture in aged patients. Methods A retrospective analysis was performed in 143 elderly patients with hip fracture, aged 75 years and over. 28 cases received non-surgery treatment and 115 cases received surgery treatment. Much of them had at least one chronic disease. The complications, preoperative preparation, operative indications, internal fixation devices, postoperative management, mortality rate and recovery rate were reviewed. Results The mortality rate of nonoperative management patients was 39.3% (11/28) in one year, and that of operative management patient was 8.7% (10/115). The recovery rate of nonoperative management patients was 28.5% (8/28) in one year, and that of operative management patients was 75.3% (79/115). Conclusions If full attention is paid to preoperative treatments, hip fracture of aged patients treated by operation is safe and effective.
