Objective: Bell's palsy rarely recurs or arises bilaterally. We describe unique oral motor sequelae that manifest with bilateral facial palsy.
Patients: Two rare patients with alternating bilateral Bell's palsy experienced compromised mouth movement, affecting eating, speaking, and air exchange, and reduced quality of life.
Interventions: Rehabilitation programs.
Main Outcome Measures: Electromyography and electroneuronography.
Results: On electromyography study, little activity of the orbicularis oris muscle was seen in any mouth or eye movement in Case 1. In Case 2, the electromyography activity of the depressor anguli oris and depressor labii inferioris muscles was stronger than that of the orbicularis oris muscle. The 2 cases demonstrated different patterns of recovery after the same subsequent treatment.
Conclusion: Different patterns of reinnervation occur in bilateral Bell's palsy. Mouth movement disturbances after bilateral Bell's palsy are most disabling when incomplete reinnervation (as suggested by electroneuronography) of the orbicularis oris muscle occurs. Misdirection of regenerating nerve fibers produces lesser levels of oral motor impairment.

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.

Background: Lyme disease is the most common tick-borne illness in the United States, and cases of Lyme disease have nearly doubled since the early 2000s. Symptoms and presentation vary based on severity of illness, with more serious complications of disease consisting of neurologic and cardiac dysfunction. Testing is often unreliable, which can lead to delayed diagnosis and management.

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.

Purpose: The SARS-CoV-2 vaccination has reduced COVID-19 infection, though facial nerve palsy (FNP) has emerged as a notable side effect of the vaccine. We evaluated the current literature on the clinical presentation and outcomes of FNP related to COVID-19 vaccination.
Methods: A comprehensive search of seven databases was conducted for studies up to January 2023.

Background: Incidence data on Facial Nerve Disorders (FND) and Bell's palsy are currently limited. Prior epidemiological studies have estimated the incidence rate of Bell's palsy to be between 11 and 53/100,000 individuals, although the most cited incidence data are from single regions or municipalities, many of which are outdated from several decades ago.
Methods: This was a retrospective cohort study of US adults from 2007 to 2022 using the Merative™ Marketscan® Research Databases.
