This article provides a review of the treatment of Bell’s facial palsy in pregnant women in recent years, detailing the progress of treatment of the disease in China and abroad in terms of Western medicine, Chinese herbal medicine, physiotherapy and acupuncture treatment. Bell’s facial palsy is a common acute peripheral neuropathy that usually occurs on only one side of the face. The incidence of Bell’s facial palsy is 20-30 per 100,000 people. 80%-85% of patients with facial palsy recover completely on their own within three months, but 15%-20% of patients still have sequelae. In view of the incidence of the disease, the population base of patients who cannot recover facial nerve function on their own is still considerable, so it is necessary to provide timely and effective treatment for this group of patients. 1. Etiology and pathogenesis The cause of Bell’s facial palsy is still inconclusive, and there are several theories. The theory of nerve ischemia; the ischemia, edema and pressure of the facial nerve caused by cold and other factors, followed by the dysfunction of the facial nerve and facial palsy. Second, the viral infection theory; many studies have shown that herpes simplex virus infection may be the cause of the onset of Bell’s facial palsy. 2. The specificity of pregnant women The probability of Bell’s facial palsy occurring in pregnant women is 10 times higher than that of the general population, with an incidence rate of 45/100,000 pregnant women. Although its pathogenesis is the same as that of the general population, the facial nerve is more prone to edema during pregnancy, leading to its compression in the facial nerve canal, which causes facial palsy [4]. On the other hand, the hormonal drugs and anti-degenerative drugs commonly used to treat Bell’s facial palsy make the medication during pregnancy quite problematic due to their adverse side effects on the fetus [5]. 3, treatment methods Drugs 3.1.1, Western drugs Some foreign literature states that prednisolone 40 mg daily can be applied, but there is a lack of discussion on the safety of hormone application on the mother and fetus. In China, scholars have applied the treatment of Bell’s facial palsy in 21 cases of pregnant women with 1600 mg per day for ten days. During the ten days of treatment, no adverse effects were observed except for one patient who experienced nausea. However, no control group was established in this study, and the development of the fetus during treatment was not reported, so the safety application of Veritin needs to be further explored. 3.1.2. Traditional Chinese medicine The formula commonly used in the treatment of facial palsy is generally based on the addition and subtraction of the main formula of Zhanzheng San. In the treatment of Bell’s facial palsy in pregnant women, blood-breaking drugs, blood-traveling drugs, and toxic drugs such as safflower, peach kernel, cow’s knee, centipede, and whole scorpion should be used with caution or even prohibited. Further research on the safety of Chinese herbal medicine in the treatment of Bell’s facial palsy in pregnant women is still needed. Physiotherapy In the acute stage, one pole is placed in front of the patient’s ear screen or facial discomfort, and the other pole is placed at the mastoid foramen behind the ear, each time for 10 minutes, once a day for ten days. During the recovery period, modulated intermediate frequency therapy is added to the ultrashort wave therapy, one pole is placed at the affected postauricular mastoid and the other pole is placed at the affected cheek, and the prescription for neuritis is chosen, and the output is limited to the patient’s tolerance, 20 minutes each time, once a day, for ten days. Acupuncture treatment Chen et al. treated 36 cases of Bell’s facial palsy in pregnant women, taking the affected side of Yangbai, Fish Waist, Silky Kong, Di Cang, Cheek Cheeks, Shuangzheng, Cheng Pao and Cataract. The above-mentioned cases were treated with G6805 electroacupuncture instrument with sparse and dense waves once every other day for 30 minutes, 10 times a course of treatment, and the total effective rate was 97.2% for 3 courses of treatment. Yi et al. treated 10 cases of Bell’s facial palsy in pregnant women, taking Yangbai, Ju s, Sun, Zygomatic s, Cheek car, Di Cang, Shuang Zheng, Feng Chi, Cataract, Waiguan, Foot San Li on the affected side and Qu Chi on the healthy side. The above acupuncture points were left for 30 minutes, and at the same time, the acupuncture points on the face were pecked and moxibustion was performed six times for one course of treatment, with a total of five courses of treatment, of which the recovery rate was 70% and the total effective rate was 100%. Xuan’s reported a case of Bell’s facial palsy in a pregnant woman, using warm acupuncture and moxibustion of the affected side of the lower Guan point for 30 minutes each time, twice a week, a total of 5 times treatment and healed. 4.Summary Bell’s facial palsy is a common clinical disease, which has a rapid onset and tends to recover on its own, but often takes several months, and facial palsy affects the appearance and brings a great psychological burden to the patient [14]. There is still a lack of definitive safety studies on fetuses with drug therapy, which makes clinicians often cautiously use or disable such drugs [16]. Although physiotherapy has no significant side effects, its efficacy needs further controlled studies. Acupuncture therapy has been used more often in the treatment of Bell’s facial palsy in pregnant women, and its efficacy is definite without side effects. If the effectiveness and safety of acupuncture therapy can be studied scientifically and systematically, and the effectiveness and safety of acupuncture therapy for Bell’s facial palsy in pregnant women can be established, it can provide a basis for clinical treatment and bring more benefits to patients.
