“…Since Korczyn [4] first reported a high frequency (66%) of diabetes mellitus (DM) in patients presenting with BP, this association has been confirmed by several researchers, most recently by Savadi-Oskouei et al [5] (prevalence of DM: 29%, the same as above). Researchers have also reported that the incidence of hypertension in patients with BP was higher than in control groups.…”

Epidemiological data of Bell's palsy (BP) have been reported. For example, the annual incidence of BP is 15-30 per 100,000 persons, with equal numbers of men and women affected, and there is no predilection for either side of the face. However, details of the relationship between BP and morphometric aspects of the facial nerve have not been available in textbooks. We performed a morphometric analysis of human facial nerve fibers and estimated the total number of myelinated axons (TN) and average transverse area of myelinated axons (ATA). The facial nerve showed a significant decrease of TN with increasing age (r = -0.77; p < 0.01), but showed no significant changes of ATA with age (r = -0.01; p = 0.96). We supposed that the TN decrease with age was a factor in the delayed recovery from BP seen in the elderly. Moreover, the TN and ATA showed no significant differences between female and male specimens (p < 0.05), or between the right and left side specimens (p < 0.05). Our present results seem to explain the absence of significant sex and affected side differences in BP.

“…There are several possible risk factors for BP, including severe preeclampsia [71], psychological factors [72], glucose metabolism abnormalities [73], radiation exposure [74], hypertension [75], and migraine [76]. Recently, epidemiological studies have revealed that the incidence of BP is also related to extreme temperature exposure.…”

The etiology of Bell’s palsy: a review

et al. 2019

Bell's palsy is the most common condition involving a rapid and unilateral onset of peripheral paresis/paralysis of the seventh cranial nerve. It affects 11.5-53.3 per 100,000 individuals a year across different populations. Bell's palsy is a health issue causing concern and has an extremely negative effect on both patients and their families. Therefore, diagnosis and prompt cause determination are key for early treatment. However, the etiology of Bell's palsy is unclear, and this affects its treatment. Thus, it is critical to determine the causes of Bell's palsy so that targeted treatment approaches can be developed and employed. This article reviews the literature on the diagnosis of Bell's palsy and examines possible etiologies of the disorder. It also suggests that the diagnosis of idiopathic facial palsy is based on exclusion and is most often made based on five factors including anatomical structure, viral infection, ischemia, inflammation, and cold stimulation responsivity.

“…In Korea, approximately 0.057% of the population is diagnosed annually with Bell's palsy 3 . The incidence of Bell's palsy is not different between the sexes and covers all age populations, with the peak incidence observed in the population aged 15-50 years old 4,5 . Because it is diagnosed by exclusion of other organic causes, the exact pathophysiologic causes of Bell's palsy remain unknown.…”

the aim of this study was to investigate the association of body mass index (BMi), alcohol consumption, and smoking status with the occurrence of Bell's palsy. the Korean national Health insurance Service-Health Screening cohort of a ≥ 40-year-old population from 2000-2003 was used. A total of 5,632 Bell's palsy participants were matched with 22,528 control participants in terms of age, sex, income, region of residence, and past medical histories of hypertension, diabetes, and dyslipidemia. Bell's palsy was classified by a history of ≥2 diagnoses with ICD-10 code (G510) and steroid treatment. BMI (kg/m 2) was classified as <18.5 (underweight), ≥18.5 to <23 (normal), ≥23 to <25 (overweight), ≥25 to <30 (obese i), and ≥30 (obese II). Alcohol consumption was divided into non-drinkers and those who drank 2-3 times a month, 1-2 times a week, and ≥3 times a week. Smoking status was categorized as current smokers, past smokers, and non-smokers. the odds of obesity, alcohol consumption, and smoking with Bell's palsy were analyzed using logistic regression analysis. BMI showed proportionally positive associations with Bell's palsy (adjusted OR [95% CI] = 0.61 [0.47-0.79] for underweight, 1.16 [1.08-1.26] for normal, 1.24 [1.15-1.33] for obese I, and 1.61 [1.38-1.88] for obese II, P < 0.001). The odds of alcohol consumption with Bell's palsy were 0.90 (95% confidence interval [CI] = 0.82-0.99) for 2-3 times a month, 0.77 (95% CI = 0.69-0.85) for 1-2 times a week, and 0.79 (95% CI = 0.71-0.88) for ≥3 times a week compared to nondrinkers (p < 0.001). Smoking did not show a relationship with the occurrence of Bell's palsy. Obesity was related to the risk of Bell's palsy in the population over 40 years old. On the other hand, alcohol consumption was negatively associated with the occurrence of Bell's palsy.
