Study On Prognostic Factors Of Facial Nerve Paralysis

Goal: The trial is trying to find the relationship among prognostic factors of idiopathic facial nerve paralysis.The prognostic factors inlude:gender,age,duration before the first visit,pathogen,season when the disease starts,syndrome,affected nerve location,regular treatment,terminal scores by 3 monthes,sequelae.Method: Make case observation tables and fill them up according to the requirment of the trial.Process the data using SPSS 12.0 software.Linear regression is applied for those continual data,while binary regression is applied for those binary data.Simple model is found after each procession,which is limited to the sig<0.05 level.Based on the models,the relationship is explained.Result: All the models are well fit.Linear model excludes the collinearity.The prediction correct is no less than 81.3 percent for all the stepwised models.Linear model:Y=92.468-0.149 duration before the first visit -1.379syndrome-4.291sequelae. None lineary model:Logit(p85)=2.823acupuncture applied with 7 days-37.261Logit(p90)=2.326spring+1.401nerve tropic drug-46.599;Logit(p95)=3.248spring+0.143scores of the first visit-2.441wind heat syndrome-2.627chonda tympani-30.052;Logit(psequelae)=2.883cutting therapy+2.021stapedial branch+1.433unclear pathogen-2.468Conclusion: Acupuncture applied within 7 days can aid in recovery.Those whose facial paralysis start in spring and who receive nerve tropic drug will have better recovery.There is no significant relationship between complete recovery and treatment.Scores of the first visit,syndrome and affected nerve location play greater role in the recovery.There is tight relationship among sequelae,affected nerve location in stapedial branch and unclear pathogen.
