1. Introduction

Bell’s Palsy, a sudden onset of facial paralysis of unknown etiology, poses a significant challenge in emergency care settings due to its acute presentation and potential long-term sequelae. With an annual incidence of approximately 20–30 cases per 100,000 individuals worldwide, Bell’s Palsy is one of the most common causes of facial nerve paralysis, often requiring immediate medical attention [1,2]. The condition typically manifests unilaterally, affecting the facial muscles on one side of the face, leading to facial distortion, difficulty in closing the eye, drooling, and impaired speech articulation [3]. While most cases of Bell’s Palsy resolve spontaneously within weeks to months, a subset of patients may experience persistent facial weakness, functional impairment, and psychological distress [4].

In the management of Bell’s Palsy, conventional treatments such as corticosteroids and antiviral agents aim to reduce inflammation, alleviate symptoms, and promote nerve recovery [5]. However, the complexity of Bell’s Palsy and the variability in patient response to standard treatments necessitate the exploration of alternative therapeutic approaches. Emerging evidence suggests a potential role for complementary therapies, such as acupuncture, in optimizing outcomes for patients with Bell’s Palsy. Acupuncture, rooted in traditional Chinese medicine principles, involves the strategic insertion of fine needles into specific acupoints along the body’s meridians to regulate the flow of qi (vital energy) and restore balance within the body’s energy system [6]. By stimulating nerve pathways and eliciting neurophysiological responses, acupuncture is hypothesized to exert therapeutic effects beyond symptomatic relief.

Despite the growing interest in acupuncture as a complementary therapy for Bell’s Palsy, the exact mechanisms underlying its therapeutic effects remain incompletely understood. Recent studies have proposed several potential mechanisms of action, shedding light on the multifaceted nature of acupuncture’s impact on the pathophysiology of Bell’s Palsy [7,8]. Acupuncture’s ability to modulate inflammation is of particular interest, as evidenced by its regulatory effects on cytokine levels and immune responses [9]. By attenuating the inflammatory cascade implicated in the pathogenesis of Bell’s Palsy, acupuncture may help alleviate facial paralysis and associated symptoms [10]. Furthermore, acupuncture-induced neuroplastic changes within the central nervous system offer insights into its capacity to facilitate functional recovery of the facial nerve and associated musculature [11]. Synaptic remodeling and enhanced neuronal connectivity may contribute to the restoration of motor function and the resolution of facial asymmetry [12].

Moreover, acupuncture’s impact on blood flow dynamics presents another potential mechanism underlying its therapeutic effects in Bell’s Palsy. Enhanced blood flow and microcirculation at the site of needle insertion have been observed, which may promote tissue healing and regeneration [13,14]. This phenomenon could facilitate the delivery of oxygen and nutrients to affected facial tissues, thereby supporting the recovery process and mitigating the severity of symptoms. The cumulative evidence suggests that acupuncture operates through a complex interplay of biological mechanisms, offering promising avenues for optimizing outcomes in the management of Bell’s Palsy.

This paper aims to review the evidence and perspectives on the use of acupuncture as a complementary therapy in the emergency management of Bell’s Palsy. By synthesizing findings from clinical trials, observational studies, and expert opinions, this review seeks to elucidate the efficacy, safety, and clinical considerations associated with acupuncture in the acute management of Bell’s Palsy in emergency care settings. Furthermore, this paper will explore patient perspectives, shared decision-making principles, and future research directions in integrating acupuncture into comprehensive treatment protocols for Bell’s Palsy.

2. Methods

A comprehensive literature search was conducted to identify relevant studies on the use of acupuncture as a complementary approach in the emergency management of Bell’s palsy. Electronic databases including PubMed, Embase, Cochrane Library, and Web of Science were searched from inception to 2023. The search strategy utilized a combination of keywords and medical subject headings (MeSH) terms related to Bell’s palsy, acupuncture, emergency care, and complementary therapies.

Studies were included if they met the following criteria: they investigated the use of acupuncture as a complementary therapy for Bell’s palsy, included patients presenting with Bell’s palsy in emergency care settings, reported outcomes related to efficacy, safety, or patient satisfaction with acupuncture treatment, were published in peer-reviewed journals, and were available in English language. The titles and abstracts of the identified articles were screened for eligibility. Full-text articles of potentially relevant studies were then assessed for inclusion based on the predefined selection criteria.

The methodological quality of the included studies was evaluated using appropriate tools, such as the Cochrane Risk of Bias Tool for randomized controlled trials and the Newcastle–Ottawa Scale for observational studies. The studies were assessed for risk of bias, methodological limitations, and the overall quality of evidence. A narrative synthesis approach was employed to summarize the findings of the included studies.

3. Theoretical Basis and Mechanisms of Acupuncture in Bell’s Palsy

Acupuncture, a cornerstone of traditional Chinese medicine (TCM), operates on principles deeply rooted in the concept of restoring balance and harmony within the body’s energetic pathways. According to TCM theory, the body’s vital energy, known as qi, flows through meridians, and disruptions in this flow can lead to various health ailments, including Bell’s Palsy. Acupuncture aims to restore the smooth flow of qi by stimulating specific acupoints along the meridians, thereby rebalancing the body’s energy and promoting healing. Additionally, TCM considers the interconnectedness of the body, mind, and spirit, acknowledging that physical ailments can stem from emotional or psychological imbalances. Therefore, acupuncture treatments often address not only the physical symptoms but also the emotional well-being of the individual, promoting holistic healing [10].

Recent studies have reported a percentage change in improvement ranging from 71% to 85% with antiviral and corticosteroid medication in Bell’s palsy cases [5,15]. Understanding this degree of improvement underscores the potential benefit of adjunctive acupuncture therapy, which has been associated with additional improvement rates ranging from 10% to 25% [13,16,17,18]. Moreover, Bell’s palsy is known to exhibit a spontaneous recovery rate of approximately 70–80% within six months of onset [1], highlighting the importance of considering the natural course of the condition when evaluating treatment options.

Acupuncture in Bell’s Palsy operates through several proposed mechanisms, each addressing different aspects of the condition’s pathophysiology. One such mechanism involves its anti-inflammatory properties. By regulating pro-inflammatory cytokines and mediators, acupuncture mitigates inflammation, reducing tissue damage and creating a conducive environment for nerve regeneration. Moreover, acupuncture fosters neuroplasticity, promoting synaptic remodeling and neuronal connectivity in the central nervous system, crucial for functional recovery [12].

Another significant facet of acupuncture’s efficacy lies in its ability to enhance blood flow and microcirculation at the affected site. This improvement facilitates the delivery of essential nutrients, oxygen, and immune cells, expediting tissue healing and regeneration. By both addressing the underlying inflammation and promoting neuroregeneration, acupuncture plays a vital role in alleviating symptoms and enhancing the overall quality of life for Bell’s Palsy patients [14].

Furthermore, acupuncture’s therapeutic effects extend to promoting neuroregeneration, which is pivotal for restoring facial nerve function in Bell’s Palsy. By inducing synaptic remodeling, neuronal connectivity, and axonal regeneration, acupuncture facilitates the restoration of facial muscle strength and mobility, leading to improved facial symmetry and function [10]. Additionally, its ability to optimize blood flow and microcirculation aids in clearing metabolic waste products and inflammatory mediators, further contributing to tissue repair and the resolution of inflammation. Through these multifaceted mechanisms, acupuncture offers comprehensive and effective treatment for Bell’s Palsy, warranting its consideration as an adjunctive therapy in clinical practice [11].

4. Evidence for Acupuncture in the Emergency Management of Bell’s Palsy

Clinical trials and observational studies have extensively explored the efficacy and safety of acupuncture as an adjunctive therapy in managing Bell’s Palsy. Kim et al. [13] conducted a comprehensive systematic review and meta-analysis, evaluating the effectiveness of acupuncture for Bell’s Palsy. Their analysis incorporated a range of randomized controlled trials (RCTs) comparing acupuncture with conventional treatments or sham acupuncture. The results from the meta-analysis revealed promising outcomes, indicating that acupuncture significantly enhanced the recovery rate and improved facial nerve function outcomes compared to conventional treatments alone. Moreover, acupuncture demonstrated a favorable safety profile, with fewer reported adverse effects, underscoring its potential as a complementary therapy for Bell’s Palsy.

Building upon these findings, additional studies such as Zhang et al. [7], Lu et al. [6], and Choi et al. [15] have contributed to the evidence base supporting the use of acupuncture in Bell’s Palsy management. Zhang et al. [7] conducted a Cochrane review assessing the effectiveness of acupuncture for Bell’s Palsy, highlighting its potential benefits in improving facial nerve function and accelerating recovery. Similarly, Lu et al. [6] proposed a systematic review protocol to further investigate the role of acupuncture in Bell’s Palsy, emphasizing the need for the rigorous evaluation and synthesis of available evidence to inform clinical practice and guideline recommendations. Furthermore, Choi et al. [19] explored the relationship between the effect of acupuncture and needling sensation and manipulation, shedding light on the potential mechanisms underlying acupuncture’s therapeutic effects in Bell’s Palsy.

In addition to systematic reviews and meta-analyses, individual RCTs have contributed valuable insights into the efficacy of acupuncture in Bell’s Palsy. For instance, Li et al. [16] conducted a randomized controlled trial comparing acupuncture with sham acupuncture in Bell’s Palsy patients, demonstrating significant improvements in facial nerve function and quality of life measures in the acupuncture group. Similarly, Yang et al. [20] investigated the efficacy of electroacupuncture combined with rehabilitation exercises, revealing superior outcomes compared to rehabilitation exercises alone. These studies collectively support the growing body of evidence highlighting the potential of acupuncture as an effective adjunctive therapy for Bell’s Palsy, warranting further investigation and integration into clinical practice.

Several key findings have emerged from the literature regarding the benefits of acupuncture in Bell’s Palsy management. Firstly, acupuncture has been consistently associated with improvements in facial nerve function, as evidenced by enhanced muscle strength, reductions in synkinesis, and the restoration of facial symmetry. Studies such as those by Li et al. [16] and Yang et al. [20] have reported significant improvements in facial nerve function scores and muscle strength following acupuncture treatment. Additionally, acupuncture has been found to provide effective pain relief for Bell’s Palsy patients, alleviating discomfort associated with facial paralysis and neuralgia. This pain-relieving effect is thought to be mediated through acupuncture’s modulation of pain perception pathways and its anti-inflammatory properties. Furthermore, acupuncture has been shown to improve overall functional outcomes, including speech articulation, eating ability, and social interactions, thereby enhancing the quality of life for Bell’s Palsy patients.

Despite the accumulating evidence supporting the efficacy of acupuncture in Bell’s Palsy management, several limitations and controversies persist in the literature. Firstly, the heterogeneity of acupuncture protocols and treatment regimens across studies makes it challenging to establish standardized guidelines for acupuncture practice in Bell’s Palsy. Variations in acupuncture techniques, such as the needling depth, frequency of sessions, and selection of acupoints, may contribute to inconsistencies in treatment outcomes and hinder direct comparisons between studies. Additionally, the lack of placebo-controlled trials with adequate blinding poses challenges in interpreting the true efficacy of acupuncture, as placebo effects and patient expectations may influence treatment outcomes. Moreover, while acupuncture is generally considered safe when performed by trained practitioners, adverse events such as needle pain, hematoma formation, and local irritation have been reported, highlighting the importance of proper training and supervision in acupuncture practice [21].

The efficacy of acupuncture in the treatment of Bell’s palsy has prompted discussions regarding its cultural influences and potential placebo effects. While Bell’s palsy often resolves spontaneously, the role of acupuncture, particularly in Asian countries where it is a traditional therapy, raises questions about cultural beliefs and philosophical perspectives influencing treatment outcomes. Studies have shown variations in acupuncture utilization and acceptance between Eastern and Western populations, suggesting that cultural factors may indeed impact perceptions of acupuncture’s efficacy [22]. Furthermore, the placebo effect is a pertinent consideration in acupuncture research, with some participants attributing its benefits to psychosomatic factors or mind–body interactions [23]. However, placebo responses are complex and multifaceted, with individual beliefs and expectations playing significant roles. While acknowledging these factors, it is essential to critically evaluate acupuncture’s therapeutic effects through robust research methodologies that account for cultural nuances and placebo responses. By doing so, we can gain a more nuanced understanding of acupuncture’s role in Bell’s palsy treatment and its potential implications for clinical practice.

In addition to exploring the efficacy of acupuncture in Bell’s palsy management, it is crucial to delve into how metabolic control, particularly in cases associated with Diabetes Mellitus (DM), influences treatment outcomes. Understanding whether acupuncture yields similar efficacy in patients with DM compared to those without this condition is essential for informing clinical practice. Research addressing this specific aspect can provide valuable insights into the nuanced considerations needed when applying acupuncture as a complementary therapy for Bell’s palsy, especially in populations with comorbidities such as DM.

The efficacy of acupuncture therapy can be influenced by various factors, including patient compliance and the experience of the practitioner. The technical complexity of acupuncture, coupled with variations in the needle depth and strength applied by different practitioners, can introduce variability in treatment outcomes and pose challenges in assessing trial consistency. These factors underscore the importance of standardized protocols, rigorous practitioner training, and comprehensive outcome assessments to ensure the reliability and reproducibility of acupuncture interventions in clinical trials.

Moving forward, future research endeavors should aim to address the existing gaps and controversies in the literature to further elucidate the role of acupuncture in Bell’s Palsy management. Well-designed randomized controlled trials with larger sample sizes and standardized acupuncture protocols are warranted to provide robust evidence of acupuncture’s efficacy and optimize treatment outcomes.

Acupuncture, a key component of traditional Chinese medicine, encompasses various techniques aimed at restoring balance and promoting healing in patients with Bell’s Palsy. Among the commonly used techniques, manual acupuncture involves the insertion of fine needles into specific acupoints along the affected meridians, targeting areas associated with facial nerve innervation and motor function [13]. The selection of acupoints may vary based on individual presentations and symptomatology, but often includes points such as Hegu (LI4), Fengchi (GB20), Yangbai (GB14), Yifeng (SJ17), Taiyang (EX-HN5), Jiache (ST6), and Dicang (ST4) to address facial paralysis, pain, and inflammation [6,13,16,19,24,25]. Additionally, electroacupuncture, which involves the application of electrical stimulation to acupuncture needles, has gained popularity for its potential to enhance nerve regeneration and muscle activation in Bell’s Palsy patients [7]. Electroacupuncture techniques may include continuous or intermittent electrical stimulation at varying frequencies and intensities, tailored to individual patient needs and treatment goals.

In emergency care settings, the timely initiation of acupuncture therapy is crucial to maximize therapeutic benefits and expedite recovery in Bell’s Palsy patients. Acupuncture treatments are typically initiated as soon as the diagnosis is confirmed, ideally within the first few days of symptom onset, to capitalize on the window of opportunity for neural plasticity and tissue regeneration [13]. The frequency and duration of acupuncture sessions may vary depending on the severity of symptoms, patients’ responses to treatment, and individualized treatment plans. In acute settings, frequent acupuncture sessions may be warranted, with daily or alternate-day treatments recommended to achieve optimal outcomes [7]. As symptoms improve and stabilize, the frequency of acupuncture sessions may be tapered down, transitioning to maintenance or follow-up treatments to consolidate gains and prevent recurrence [6]. Additionally, the duration of acupuncture treatment may range from several days to weeks, with ongoing assessment and adjustments made based on patients’ progress and treatment goals.

Moving forward, future research endeavors should aim to address the existing gaps and controversies in the literature to further elucidate the role of acupuncture in Bell’s Palsy management. Well-designed randomized controlled trials with larger sample sizes and standardized acupuncture protocols are warranted to provide robust evidence of acupuncture’s efficacy and optimize treatment outcomes [13]. Additionally, comparative effectiveness studies comparing acupuncture with conventional treatments and other complementary therapies could offer valuable insights into the relative benefits and limitations of different treatment modalities [7]. Furthermore, interdisciplinary collaboration between clinicians, researchers, and traditional Chinese medicine practitioners is essential to integrate acupuncture into comprehensive care pathways for Bell’s Palsy patients, ensuring personalized and holistic approaches to treatment and rehabilitation [6].
