[Bilateral facial palsy: an atypical presentation of Lyme disease (a case report)]. / Paralysie faciale bilatérale : une présentation atypique d'une maladie de Lyme (cas clinique).

Lyme neuroborreliosis is a rare zoonosis which can be difficult to diagnose, in particular in low endemic areas. We here report the case of a 35-year-old man presenting with disabling back pain preceded by facial monoplegia, which was wrongly treated as Bell's palsy (paralysis a frigore) and then as post-traumatic lumbosciatica. The onset of facial diplegia allowed for a definitive diagnosis. The patient was treated with ceftriaxone and symptoms gradually improved.

A Rare Multinuclear Lesion Secondary to Multifactorial Ischemic Stroke: A Case Report on Eight-and-a-Half Syndrome.

Internuclear ophthalmoparesis (INO) is a horizontal eye movement disorder that is associated with a lesion at the medial longitudinal fasciculus (MLF). One-and-a-half syndrome occurs when the lesion involves the MLF and the ipsilateral abducens nuclei or the paramedian pontine reticular formation (PPRF) in the dorsomedial tegmentum of the pons. When the lesion is large enough, the fascicles of the facial nerve (CNVII) can also be involved, resulting in an ipsilateral facial nerve palsy. In combination with one-and-a-half syndrome, this condition becomes eightand- a- half syndrome (EHS). Here, we describe a unique case of EHS in a 72-year-old male with multiple ischemic stroke risk factors who presented with INO, conjugate gaze palsy, ipsilateral facial palsy, and a transient contralateral hemiparesis. Recognizing this pattern of neurologic deficits improves localization of the lesion, prevents misdiagnosis of Bell's Palsy, and expedites proper treatment.

Case report: Bilateral facial palsy with paresthesias and positive anti-GT1a antibodies.

Bilateral facial palsy with paresthesia (FDP) is a rare variant of GBS, characterized by simultaneous bilateral facial palsy and paresthesia of the distal limbs. Mounting evidence indicates that the presence of anti-GT1a IgG has a pathogenic role as an effector molecule in the development of cranial nerve palsies in certain patients with GBS, whereas anti-GT1a antibody is rarely presented positive in FDP. Here, we report the case of a 33-year-old male diagnosed with FDP presented with acute onset of bilateral facial palsy and slight paresthesias at the feet as the only neurological manifestation. An antecedent infection with no identifiable reason for the fever or skin eruptions was noted in the patient. He also exhibited cerebrospinal fluid albuminocytologic dissociation and abnormal nerve conduction studies. Notably, the testing of specific serum anti-gangliosides showed positive anti-GT1a IgG/IgM Ab. The patient responded well to intravenous immunoglobulin therapy. This case brings awareness to a rare variant of GBS, and provides the first indication that anti-GT1a antibodies play a causative role in the development of FDP. The case also suggests that prompt management with IVIG should be implemented if FDP is diagnosed.

A Rare Case of Hyperglycemia, Ketoacidosis, and Central Facial Paralysis in a Newly-Diagnosed Diabetic Woman.

BACKGROUND Diabetes mellitus is a chronic disease that occurs when the pancreas does not produce enough insulin or when the body is unable to effectively use the insulin it produces. Uncontrolled diabetes mellitus is usually associated with neurological manifestations, such as hemichorea, focal epileptic seizures, peripheral neuropathy, and peripheral facial paralysis. This report describes a 59-year-old woman presenting with hyperglycemia and ketoacidosis due to newly diagnosed diabetes mellitus, as well as a temporary episode of central facial paralysis, which regressed within a few days after medical treatment and metabolic correction. CASE REPORT A 59-year-old patient with hypertension and a family history of diabetes mellitus presented with polyuro-polydipsic syndrome and signs of metabolic ketoacidosis, with an elevated anion gap, compatible with newly discovered type 1 diabetes mellitus. Six hours after admission, we noted the abrupt onset of left central facial paralysis, with no brain damage shown on magnetic resonance imaging. Initially, the diagnosis was transient ischemic attack. After a second, normal cerebral magnetic resonance image on the fourth day, and clinical improvement on the fifth day after metabolic correction by insulin therapy and rehydration, the diagnosis of a regressive central facial paralysis was retained. CONCLUSIONS Central facial paralysis in diabetic ketoacidosis is a rare neuroendocrine entity. The pathophysiological mechanisms that can explain the occurrence of central facial paralysis are not yet described and require further investigation. This report highlights the importance of diagnosis, early management of hyperglycemia and diabetic ketoacidosis, and reversibility of central facial paralysis after treatment.

Analysis of factors associated with patients' global impression of change scores in inpatients with peripheral facial palsy: A retrospective study at a Korean Medicine Hospital.

The incidence of peripheral facial palsy is on the rise, with psychological issues influencing quality of life due to visible symptoms. Consequently, patient-reported outcome measures are critical in assessing the disease burden and the treatment efficacy of peripheral facial palsy from patients' perspective. This study examines factors influencing patients' global impression of change (PGIC) scores, a type of patient-reported outcome measure, in hospitalized patients with peripheral facial palsy. This retrospective study analyzed the electronic medical records of 200 patients with peripheral facial palsy who were admitted to the Korean Medicine Hospital, Kyung Hee University Medical Center from May 1, 2022 to April 30, 2023. Impact of demographic, electrophysiological, intervention, and clinical factors on PGIC scores were evaluated. Descriptive statistics showed that the length of hospitalization (P = .020), time from disease onset to hospitalization (P = .022), lacrimal disorders (P = .002), House-Brackmann (HB) grade evaluated at admission (P = .016) and at discharge (P < .001), improvement in HB-grade from admission to discharge (P = .002), and total facial disability index (FDI) score at discharge (P < .001) were significantly associated with PGIC scores. In multivariate logistic regression analysis, HB-grade at admission (OR: 13.89, 95% CI: 2.18-113.60), length of stay (OR: 0.27, 95% CI: 0.07-0.92), time from disease onset to hospitalization (OR: 5.55, 95% CI: 1.36-24. 77), tear-related symptoms (OR: 0.41, 95% CI: 0.17-0.96), total FDI score (OR: 0.45, 95% CI: 0.20-0.98), and greater improvement in HB-grade at discharge compared to admission (OR: 0.08, 95% CI: 0.02-0.31) were significantly associated with PGIC scores. Patients with milder initial disease severity, hospitalization period exceeding 7 days, shorter time from disease onset to hospitalization, improvement of lacrimal symptoms, total FDI score, and HB-grade between admission and discharge experienced more significant subjective improvement in peripheral facial palsy.

Immediate Facial Nerve Palsy Secondary to Otological Surgery: A Systematic Review and Narrative Synthesis.

OBJECTIVES: Iatrogenic facial nerve palsy following otological surgery is a devastating complication that results in adverse aesthetic and functional outcomes. This study aims to review studies that have reported cases of immediate facial nerve palsy to learn why and where injuries occurred and to assess outcomes following management. DATABASES REVIEWED: MEDLINE, Embase, Cochrane CENTRAL, and Pubmed up to June 20, 2023. METHODS: Clinical studies of immediate facial nerve palsies following middle ear and cochlear implantation surgery were included. Risk of bias was examined using the Brazzelli risk of bias tool. Due to the inconsistency in reporting of outcomes, we were unable to perform a meta-analysis. RESULTS: Of 234 studies identified, 11 met the inclusion criteria. The most common causes of injury were excessive drilling, use of sharp hooks to remove disease, or disorientation of the surgeon secondary to bleeding or inflammation. Variable usage of preoperative computed tomography (CT) imaging and intraoperative facial nerve monitoring was reported. The tympanic segment was the most common site of injury. A variety of surgical techniques were employed to approach the facial nerve injury including facial nerve decompression, direct closure, and repair using an autologous nerve graft. CONCLUSIONS: Otological surgeons should consider utilizing preoperative CT imaging to establish a three-dimensional mental image of key landmarks and anatomical variations before embarking on surgery. Intraoperative FN monitoring enables safe practice. Despite these measures, complex disease processes and hostile intraoperative conditions can present difficulty. Multiple treatment options are available to treat the underlying injury.

Intelligent bell facial paralysis assessment: a facial recognition model using improved SSD network.

With the continuous progress of technology, the subject of life science plays an increasingly important role, among which the application of artificial intelligence in the medical field has attracted more and more attention. Bell facial palsy, a neurological ailment characterized by facial muscle weakness or paralysis, exerts a profound impact on patients' facial expressions and masticatory abilities, thereby inflicting considerable distress upon their overall quality of life and mental well-being. In this study, we designed a facial attribute recognition model specifically for individuals with Bell's facial palsy. The model utilizes an enhanced SSD network and scientific computing to perform a graded assessment of the patients' condition. By replacing the VGG network with a more efficient backbone, we improved the model's accuracy and significantly reduced its computational burden. The results show that the improved SSD network has an average precision of 87.9% in the classification of light, middle and severe facial palsy, and effectively performs the classification of patients with facial palsy, where scientific calculations also increase the precision of the classification. This is also one of the most significant contributions of this article, which provides intelligent means and objective data for future research on intelligent diagnosis and treatment as well as progressive rehabilitation.

[Sir Charles Bell (1774-1842) and his contribution to neurology (the 250th anniversary of the birth)]. / Ser Charl'z Bell (1774­1842) i ego vklad v nevrologiyu (k 250-letiyu so dnya rozhdeniya).

Sir Charles Bell (1774-1842) is Scottish physiologist, surgeon, artist, philosopher and anatomist. Throughout his professional career, Charles Bell made a number of important discoveries and published a large number of scientific papers. Bell first presented a detailed description of the clinical picture of facial palsy (later named after him) and a number of other neurological disorders, as well as important information about referred pain and reciprocal inhibition. Exploring the physical expression of emotions, Bell described the anatomical basis of facial expressions, which became the basis and incentive for Charles Darwin's work in this direction. Being a talented artist, the scientist himself illustrated his publications. Bell was one of the first to integrate scientific research in neuroanatomy with clinical practice. His most significant discoveries are collected in the book «The Nervous System of the Human Body¼ (1830). A number of neurological conditions and patterns were named after him.

Establishment of Facial Nerve Injury Rat Model for Idiopathic Facial Paralysis Research.

Idiopathic facial paralysis is the most common type of facial nerve injury, accounting for approximately 70% of peripheral facial paralysis cases. This disease can not only lead to a change in facial expression but also greatly impact the psychology of patients. In severe cases, it can affect the normal work and life of patients. Therefore, the research on facial nerve injury repair has important clinical significance. In order to study the mechanism of this disease, it is necessary to carry out relevant animal experiments, among which the most important task is to establish an animal model with the same pathogenesis as human disease. The compression of the facial nerve within the petrous bone, especially the nerve trunk at the junction of the distal end of the internal auditory canal and the labyrinthine segment, is the pathogenesis of idiopathic facial paralysis. In order to simulate this common disease, a compression injury model of the main extracranial segment of the facial nerve was established in this study. The neurological damage was evaluated by behavioral, neuroelectrophysiological, and histological examination. Finally, 50 g constant force and 90 s clamp injury were selected as the injury parameters to construct a stable idiopathic facial paralysis model.

Use of athletic tape in the speech-language-hearing treatment of post-stroke facial paralysis in the acute phase. / Utilização da bandagem elástica funcional no tratamento fonoaudiológico da paralisia facial pós-AVC na fase aguda.

PURPOSE: To verify the efficacy of using athletic tape associated with myofunctional therapy in the speech-language-hearing treatment of facial palsy after stroke in the acute phase. METHOD: Randomized controlled clinical study with 88 patients with facial palsy in the acute phase of stroke. The sample was allocated in: Group 1: rehabilitation with orofacial myofunctional therapy and use of athletic tape on the paralyzed zygomaticus major and minor muscles; Group 2: rehabilitation alone with orofacial myofunctional therapy on the paralyzed face; Group 3: no speech-language-hearing intervention for facial paralysis. In the evaluation, facial expression movements were requested, and the degree of impairment was determined according to the House and Brackmann scale. Movement incompetence was obtained from measurements of the face with a digital caliper. After the evaluation, the intervention was carried out as determined for groups 1 and 2. The participants of the three groups were reassessed after 15 days. The statistical analysis used was the generalized equations. RESULTS: The groups were homogeneous in terms of age, measure of disability and functioning, severity of neurological impairment and pre-intervention facial paralysis. Group 1 had a significant improvement in the measure from the lateral canthus to the corner of the mouth, with better results than groups 2 and 3. CONCLUSION: The athletic tape associated with orofacial myofunctional therapy had better results in the treatment of facial paralysis after stroke in the place where it was applied.

OBJETIVO: Verificar a eficácia do uso da bandagem elástica funcional associada à terapia miofuncional no tratamento fonoaudiológico da paralisia facial pós-acidente vascular cerebral na fase aguda. MÉTODO: Estudo clínico controlado randomizado com 88 pacientes com paralisia facial na fase aguda do acidente vascular cerebral. A amostra foi alocada em: Grupo 1: reabilitação com terapia miofuncional orofacial e utilização da bandagem elástica funcional nos músculos zigomáticos maior e menor paralisados; Grupo 2: reabilitação apenas com terapia miofuncional orofacial na face paralisada; Grupo 3: sem qualquer intervenção fonoaudiológica para paralisia facial. Na avaliação foram solicitados os movimentos de mímica facial e o grau do comprometimento foi determinado de acordo com a escala de House e Brackmann.

Os participantes dos três grupos foram reavaliados após 15 dias. A análise estatística utilizada foi das equações generalizadas. RESULTADOS: Os grupos foram homogêneos quanto à idade, medida de incapacidade e funcionalidade, gravidade do comprometimento neurológico e da paralisia facial pré-intervenção. O grupo 1 teve melhora significativa na medida canto externo do olho à comissura labial, com melhores resultados quando comparado aos grupos 2 e 3. CONCLUSÃO: A bandagem elástica funcional associada a terapia miofuncional orofacial apresentou melhor resultado no tratamento da paralisia facial após acidente vascular cerebral no local onde foi aplicado.

Management of facial nerve trauma.

PURPOSE OF REVIEW: To present the current literature on management of facial nerve disorder secondary to trauma, with a focus on the utility of electrodiagnostic testing in this setting. RECENT FINDINGS: Patients with facial palsy related to temporal bone fractures should be started on high-dose corticosteroids as early as possible. Recent literature on the benefit of surgical intervention in the setting of temporal bone fracture is mixed. Some studies support early surgical decompression whereas others have found no benefit compared with conservative treatment. SUMMARY: The management of facial nerve trauma is based on location and extent of injury. Extratemporal trauma and transected nerve should be treated with surgical exploration and tension-free coaptation ideally within 72 h. There are no guidelines for intratemporal facial nerve trauma. Surgical decompression compared with medical management is debated in the literature without consensus and more large studies are needed.

Applications of artificial intelligence in facial plastic and reconstructive surgery: a systematic review.

PURPOSE OF REVIEW: Arguably one of the most disruptive innovations in medicine of the past decade, artificial intelligence is dramatically changing how healthcare is practiced today. A systematic review of the most recent artificial intelligence advances in facial plastic surgery is presented for surgeons to stay abreast of the latest in our field. RECENT FINDINGS: Artificial intelligence applications developed for use in perioperative patient evaluation and management, education, and research in facial plastic surgery are highlighted. Selected themes include automated facial analysis with landmark detection, automated facial palsy grading and emotional assessment, generation of artificial facial profiles for testing and model training, automated postoperative patient communications, and improving ethnicity-sensitive facial morphometry norms. Inherent bias can exist in artificial intelligence models, and care must be taken to utilize algorithms trained with diverse datasets. SUMMARY: Artificial intelligence tools are helping clinicians provide more standardized, objective, and efficient care to their patients. Increasing surgeon awareness of available tools, and their widespread implementation into clinical workflows are the next frontier. Ethical considerations must also shape the adoption of any artificial intelligence functionality. As artificial intelligence applications become a fixture in medicine, surgeons must employ them effectively to stay at the vanguard of modern medicine.

Facial Nerve Pathology in Children.

Facial nerve pathology in children has devastating functional and psychosocial consequences. Facial palsy occurs less commonly in children than adults with a greater proportion caused by congenital causes. Most pediatric patients have normal life expectancy and few comorbidities and dynamic restoration of facial expression is prioritized. This article will focus on the unique aspects of care for facial palsy in the pediatric population.

Dual-plane lift-and-hold technique for brow ptosis in young patients with facial paralysis.

BACKGROUND: Direct browlift is useful but leaves a scar above the brow. We proposed a dual-plane browlift to avoid facial scarring while effectively resolving brow ptosis in young and young adult patients. METHODS: Seven patients with facial palsy underwent dual-plane browlift between July 2018 and June 2022. The mean postoperative follow-up period was 31.9 months. Skin resection at the hairline was combined with subcutaneous dissection down to the inferior margin of the brow to "lift" the brow. Fascia lata strips were fixed to the dermis just inferior to the eyebrow to "hold" the brow, and the strips were suspended upward through the subperiosteal tunnel and fixed to the periosteum. Brow height was compared before and after the procedure and with the contralateral side. RESULTS: The reported complications included slight hematoma at the recipient site, temporary difficulty in closing the eye, and seroma at the fascia donor site. The paralyzed side showed significant differences between the preoperative period and postoperative months (POM) 3, 6, and 12, but differences were not shown in the intervals between POM 3 and 6, 6 and 12, or 3 and 12. The difference in eyebrow height between the paralyzed and nonparalyzed sides was significant preoperatively but not at POM 3, 6, or 12. All scars matured well, and the fascia silhouette was not visible in the forehead region. CONCLUSIONS: Dual-plane browlift enables rigid suspension using the fascia lata and excises flaccid skin without leaving facial scars, yielding excellent cosmetic quality and stable long-term outcomes.

Clinical Experience With Acute Phase Repair of Facial Nerve Dissections.

The purpose of this study was to evaluate the facial nerve recovery of patients with traumatic facial nerve transections after tension-free end-to-end nerve epineural anastomosis during the acute phase. A total of 11 patients with traumatic facial nerve transections during the acute phase were surgically treated in the authors' department from November 2016 to August 2022. The case data and imaging data were collected from the patients, and the House-Brackman evaluation system of the facial nerve was applied to assess the recovery of facial nerve function, and the higher the grade, the worse the facial nerve function. Of the patients, 90.9% recovered to H-B grade II or below, and there were differences in the degree of recovery of the facial nerve function among the branches, and the ones that recovered to H-B grade II or below after surgery were 100% of the zygomatic branch, of which 80% were H-B grade I, 100% of the buccal branch, of which 44.4% were H-B grade I, 88.9% of the marginal mandibular branch, and 66.7% of the temporal branch. The study showed that the recovery rate of young patients was better than that of middle-aged and old people, and the best recovery of each branch of the facial nerve was the zygomatic branch, followed by the buccal branch, the marginal mandibular branch, and the worse was the temporal branch.

[Repetitive transcranial acupuncture stimulation combined with electroacupuncture in treatment of acute facial palsy with retroauricular pain: a randomized controlled trial].

OBJECTIVE: To observe the clinical effect of repetitive transcranial acupuncture stimulation (rTAS) combined with electroacupuncture (EA) in treatment of acute facial palsy with retroauricular pain. METHODS: Sixty-eight patients of acute facial palsy with retroauricular pain were randomly divided into an observation group (34 cases, 3 cases dropped out) and a control group (34 cases, 3 cases dropped out). On the basis of conventional therapy, in the control group, Yangbai (GB 14), Cuanzhu (BL 2), Sibai (ST 2), Quanliao (SI 18), Dicang (ST 4), Yifeng (TE 17), Qianzheng (Extra point) and Taiyang (EX-HN 5) on the affected side, and bilateral Hegu (LI 4) were selected. EA was attached to Yangbai (GB 14) and Cuanzhu (BL 2), and Sibai (ST 2) and Dicang (ST 4), respectively, using intermittent wave. In the observation group, on the basis of the regimen as the control group, rTAS was delivered at Baihui (GV 20) and the 1/5 of the lower motor area on the bilateral sides; EA of dense wave was given at the sites of the mastoidⅠand Ⅱ. The intervention of each group was delivered once a day, 6 times a week as one course for 4 courses and taking a day off every course. Before treatment and at the moment after the first treatment completion, the score of visual analogue scale (VAS) was observed in the two groups and the days of retroauricular pain were recorded. Before and after treatment, the score of Sunnybrook facial grading system (SFGS), the grade of House-Brackmann facial nerve function evaluation system (H-B), the latency and amplitude of the motor conduction from the foramina stylomastoideum to the frontal muscle, the orbicularis oris muscle and the orbicularis oculi muscle on the affected facial nerve, were observed in the patients of two groups and the clinical effect was compared between the two groups after treatment. RESULTS: After treatment, SFGS score was increased (P<0.05), H-B grade was improved (P<0.05), the latency was shortened in the motor conduction from the foramina stylomastoideum to the frontal muscle, the orbicularis oris muscle and the orbicularis oculi muscle on the affected facial nerve (P<0.05) and its amplitude elevated (P<0.05) when compared with those before treatment in the two groups. In the observation group, SFGS score was higher (P<0.05), H-B grade was superior (P<0.05), the latency was shorter in the motor conduction from the foramina stylomastoideum to the frontal muscle, the orbicularis oris muscle and the orbicularis oculi muscle on the affected facial nerve (P<0.05) and its amplitude was higher (P<0.05) when compared with those of the control group after treatment. After the completion of the first treatment, VAS score of either group was reduced in comparison with that before treatment (P<0.05), and the score in the observation group was lower than that of the control group (P<0.05). The duration of retroauricular pain was shortened in the observation group when compared with that of the control group (P<0.05). The total effective rate was 87.1% (27/31) in the observation group, which was higher than 77.4% (24/31) of the control group (P<0.05). CONCLUSION: The rTAS combined with EA is effective for reducing neurologic impairment of acute facial palsy and alleviating retroauricular pain in the patients.

Spatial functional reorganizations can serve as potential biomarkers of post facial palsy synkinesis.

Facial palsy can result in a serious complication known as facial synkinesis, causing both physical and psychological harm to the patients. There is growing evidence that patients with facial synkinesis have brain abnormalities, but the brain mechanisms and underlying imaging biomarkers remain unclear. Here, we employed functional magnetic resonance imaging (fMRI) to investigate brain function in 31 unilateral post facial palsy synkinesis patients and 25 healthy controls during different facial expression movements and at rest. Combining surface-based mass-univariate analysis and multivariate pattern analysis, we identified diffused activation and intrinsic connection patterns in the primary motor cortex and the somatosensory cortex on the patient's affected side. Further, we classified post facial palsy synkinesis patients from healthy subjects with favorable accuracy using the support vector machine based on both task-related and resting-state functional magnetic resonance imaging data. Together, these findings indicate the potential of the identified functional reorganizations to serve as neuroimaging biomarkers for facial synkinesis diagnosis.

Global and regional burden of vaccine-associated facial paralysis, 1967-2023: Findings from the WHO international pharmacovigilance database.

The scarce and conflicting data on vaccine-associated facial paralysis limit our understanding of vaccine safety on a global scale. Therefore, this study aims to evaluate the global burden of vaccine-associated facial paralysis and to identify the extent of its association with individual vaccines, thereby contributing to the development of a more effective vaccination program. We used data on vaccine-associated facial paralysis from 1967 to 2023 (total reports, n = 131 255 418 418) from the World Health Organization International Pharmacovigilance Database. Global reporting counts, reported odds ratios (ROR), and information components (ICs) were computed to elucidate the association between the 16 vaccines and the occurrence of vaccine-associated facial paralysis across 156 countries. We identified 26 197 reports (men, n = 10 507 [40.11%]) of vaccine-associated facial paralysis from 49 537 reports of all-cause facial paralysis. Vaccine-associated facial paralysis has been consistently reported; however, a pronounced increase in reported incidence has emerged after the onset of the coronavirus disease 2019 (COVID-19) pandemic, which is attributable to the COVID-19 mRNA vaccine. Most vaccines were associated with facial paralysis, with differing levels of association, except for tuberculosis vaccines. COVID-19 mRNA vaccines had the highest association with facial paralysis reports (ROR, 28.31 [95% confidence interval, 27.60-29.03]; IC, 3.37 [IC0.25, 3.35]), followed by encephalitis, influenza, hepatitis A, papillomavirus, hepatitis B, typhoid, varicella-zoster, meningococcal, Ad-5 vectored COVID-19, measles, mumps and rubella, diphtheria, tetanus toxoids, pertussis, polio, and Hemophilus influenza type b, pneumococcal, rotavirus diarrhea, and inactivated whole-virus COVID-19 vaccines. Concerning age- and sex-specific risks, vaccine-associated facial paralysis was more strongly associated with older age groups and males. The serious adverse outcome and death rate of vaccine-associated facial paralysis were extremely low (0.07% and 0.00%, respectively). An increase in vaccine-induced facial paralysis, primarily owing to COVID-19 mRNA vaccines, was observed with most vaccines, except tuberculosis vaccines. Given the higher association observed in the older and male groups with vaccine-associated facial paralysis, close monitoring of these demographics when administering vaccines that are significantly associated with adverse reactions is crucial.
