Purpose: Idiopathic facial palsy is called as Bell's palsy and reports showed that facial paralysis increased during COVID-19 pandemic period. There are many reports about the relationship between COVID-19 and facial paralysis but there is no prospective study. SARS-CoV-2 IgG and IgM antibodies increase in COVID-19. Our purpose is to investigate SARS-CoV-2 IgG + IgM antibody in the Bell's palsy.
Methods: Prospective cross-sectional study was planned. Patients with acute peripheral facial paralysis with no reason and diagnosed as Bell's palsy was included in the study. In order to investigate SARS-CoV-2 in the etiologies of these patients, SARS-CoV-2 IgM + IgG (total) test was studied. SARS-CoV-2 IgG + IgM was measured by using the ADVIA Centaur® test kit. Test reports result in index values and as nonreactive or reactive. The results were analyzed.
Results: Forty-one patients were included in the study. The average age of the patients was 41,7. 17 (41,4%) were female and 24 (58,6%) were male. 21 patients had left-sided; 20 had right-sided paralysis. SARS-CoV-2 IgG + IgM values were measured two times of the patients. First control was in the first week of facial paralysis, 10 (24,3%) positivity was found. The average index of the positive patients were 6,74 (min.1,39-max.10) in the first control and 9,585 in the second control (min.8,7-max. 10).
Conclusion: We found that the SARS-CoV-2 IgM + IgG antibody test was positive in 24.3% of the patients with Bell's palsy. The results are higher than the seroprevalence studies conducted in asymptomatic individuals. Facial paralysis could be the only symptom of COVID-19 but further studies must be done.

Marin Amat syndrome is a phenomenon in which eyelids close upon opening of the mouth during the recovery phase after facial nerve paralysis. In this report, we present two surgically treated cases of Marin Amat syndrome with aponeurotic ptosis. Case 1: A 66-year-old man had developed left Bell's palsy a year prior to presentation and underwent rehabilitation at the Neurology Department of Japan Community Healthcare Organization Chukyo Hospital.

The sharing of multimodal magnetic resonance imaging (MRI) data is of utmost importance in the field, as it enables a deeper understanding of facial nerve-related pathologies. However, there is a significant lack of multi-modal neuroimaging databases specifically focused on these conditions, which hampers our comprehensive knowledge of the neural foundations of facial paralysis. To address this critical gap and propel advancements in this area, we have released the Multimodal Neuroimaging Dataset of Meige Syndrome, Facial Paralysis, and Healthy Controls (MND-MFHC).

Removal of the buccal fat pad can be considered safe as long as there is a detailed analysis of anatomical landmarks. The objective of this study was to estimate the prevalence of intra- and postoperative complications resulting from buccal fat pad removal through a systematic review. The search strategy involved observational and/or interventional studies in humans that included at least one case of buccal fat pad removal with a description of the surgery, postoperative progress, and complications.

Bell's palsy (BP) is a neurological disorder characterized by sudden unilateral peripheral facial paralysis. The etiology in children remains largely unknown, and standardized management strategies are lacking. The aim of this retrospective cohort study is to evaluate clinical features, laboratory markers, and therapeutic options associated with recovery to identify potential prognostic factors and validate therapeutic strategies, with a particular focus on the role of corticosteroids and vitamin supplementation.

Objective: To report ocular examination findings before and after total ear canal ablation and lateral bulla osteotomy (TECALBO) and ventral bulla osteotomy (VBO) in cats and dogs.
Methods: At The Ohio State University and MedVet Columbus, ophthalmic examinations were performed on client-owned animals for which a TECALBO or VBO was indicated. Examination findings and postoperative complications relating to ophthalmic and/or neuro-ophthalmic diseases were recorded prior to surgery (T0) and at 1 day (T1), 2 to 3 weeks (T14), and ± 2 months (T60) postoperatively.
