The correlation analysis among age and clinical and imageological characteristics for orbital blow-out fractures

Abstract

Objective To analyze and compare the clinical and imageological characteristics of or- bital blow-out fractures between juvenile and adult,and analyze the correlation between clinical manifestations and imageological characteristics.Help the clinicians to analyze patients,conditions roundly and carefully and make reasonable treatment proposals.Methods Collected 75 patients with isolated orbital blow-out fracture whom clinical and imageological materials were completed from October 2006 to December 2008.All patients were divided into two groups:juvenile (≤18 years old,20 Cases) and adult (19-56 years old,55 cases).The ill history,clinical and imageological characteristics and the operative findings of all the cases were summarized. Meanwhile.statistical analysis was made.Results The main:reasons of orbital fractures were fall and violence in juvenile group and that in adult group were vehicle accident and violence.The difference of constituent ratio about gender and involved eyes between two groups had no statistical significance(P>0.05).The severity of enophthalmos in juvenile group was lower than in adult group (P<0.05).The constituent ratio of nauseavomit after being hurt,linear or trapdoor type fracture,muscle incarceration as well as muscle congestion were higher. in juvenile group than in adult group (P<0.05).The difference of constituent ratio about involved orbital floors between two groups had statistical significance (P<0.05).There was no difference of simple medial wall fracture between two groups (P<0.05).Conclusions There are obvious differences between juvenile and adult orbital blow-out fractures in clinical and imageological characteristics.They all have their own special features,by the combination of clinic and imageology,we can evaluate the patients,condition exactly and make reason- able treatment proposals in time.
