Objectives: This research was conducted to investigate the factors that affect the level of facial nerve damage.
Methods: From October 2009 to September 2013, the total number of 581 patients of Bell’s palsy and Ramsay-Hunt syndrome visited Facial Palsy Center in Kyung Hee University Hospital at Gangdong for Traditional Korean and Western combined medical treatment. Of these, 453 patients of peripheral facial nerve palsy were selected for the research. After reviewing the medical records that have details of age, gender, diagnosis(Bell’s palsy and Ramsay-Hunt syndrome), onset, underlying diseases(DM, HTN), and HbAlc value, the analysis on the influence factors on the level of facial nerve damage was drew out.
Results: The axonal loss rate of oris branch and nasal branch were significantly higher than the axonal loss rate of frontal branch and oculi branch. In addition, the frequency of becoming a major damaged branch was also high in the oris branch nasal branch. The factors by month, weather, smoking, and alcohol did not influence EMG axonal loss rate. Male rather than female and patient with Rasmay-Hut syndrome rather than Bell’s palsy had a higher axonal loss rate in all branches. Of those, front of branch of male was remarkably higher than female. Patient with DM as P/H had high axonal loss rate in all branches. Patient with HTN as P/H had high axonal loss rate in all branches except for oris branches. Patients with DM and HTN group had significantly higher value from the average of axonal loss rate than patients who are only with HTN and without DM/HTN. DM alone group had significantly higher value than patients who are without DM/HTN. However, HTN alone was not significantly high. By analysing HbAlc of the patients who were hospitalised regardless DM, axonal loss rate was high in the order of DM group, preDM group, normal group. Nevertheless, only DM group showed higher axonal rate statistically than normal group. Considering DM and HbA1c value, the patients can be divided into 4 different groups of hkDM, lkDM, hfDM and nDM. By analysing those groups, the average damaged value of the groups with diagnosis followed by treatment(lkDM, hkDM) were higher than the average rate of hfDM and statistically higher than the rate of the nDM.
Conclusions: The influential factors of increasing the level of EMG damage are male(only for the frontal branch), age above sixties, HTN, DM, and HbAlc value above 6.5. Besides, the negligible factors are month, season, diagnosis, alcohol, and smoking. Further research including clinical prognosis should be conducted.
