Bell's palsy is the most common condition involving a rapid and unilateral onset of peripheral paresis/paralysis of the seventh cranial nerve. It affects 11.5-53.3 per 100,000 individuals a year across different populations. Bell's palsy is a health issue causing concern and has an extremely negative effect on both patients and their families. Therefore, diagnosis and prompt cause determination are key for early treatment. However, the etiology of Bell's palsy is unclear, and this affects its treatment. Thus, it is critical to determine the causes of Bell's palsy so that targeted treatment approaches can be developed and employed. This article reviews the literature on the diagnosis of Bell's palsy and examines possible etiologies of the disorder. It also suggests that the diagnosis of idiopathic facial palsy is based on exclusion and is most often made based on five factors including anatomical structure, viral infection, ischemia, inflammation, and cold stimulation responsivity.

Bell's palsy is the most common diagnosis associated with facial nerve weakness or paralysis. However, not all patients with facial paresis/paralysis have Bell's palsy. Other common causes include treatment of vestibular schwannoma, head and neck tumours, iatrogenic injuries, Herpes zoster, or trauma. The approach to each of these conditions varies widely. The purpose of this guideline is to provide clinicians with guidance on the treatment and monitoring of patients with different causes of facial paralysis. We intend to draft a practical guideline, focusing on operationalised recommendations deemed to be useful in the daily management of patients. This guideline was promoted by the Spanish Society of Otolaryngology and developed by a group of physicians with an interest in facial nerve disorders, including at least one physician from each Autonomous Community. In a question and answer format, it includes 56 relevant topics related to the facial nerve.

By targeting receptors that serve to downregulate the cellular immune system, monoclonal antibodies such as ipilimumab and nivolumab have transformed the management of metastatic melanoma, and their use is referred to as immune checkpoint therapy (ICT). However, because the antitumoral activity of these agents is achieved through the reversal of mechanisms that naturally serve to temper the immune response, the potential for adverse reactions secondary to autoimmunity is of clinical significance. Neurological immune-related adverse events (irAEs) may occur consequent to ICT, and the development of autoimmune Bell's palsy is a specific, uncommon manifestation of the body's immune response against the seventh cranial nerve, resulting in acute paresis of facial muscles. We describe 2 cases of autoimmune Bell's palsy following the administration of combination ICT using ipilimumab and nivolumab in 2 patients with metastatic melanoma. The use of a steroid taper in addition to the cessation of combination immunotherapy resulted in resolution of symptoms for both patients. In the first case, the patient was subsequently started on nivolumab monotherapy but developed autoimmune polyneuropathy, and immunotherapy was discontinued indefinitely. In the second case, the initiation of nivolumab monotherapy following resolution of symptoms resulted in an inadequate antitumoral response. Subsequent transition to treatment with encorafenib/binimetinib initially provided a positive response but also required discontinuation secondary to irAEs. Both of these cases demonstrate the potential for autoimmune Bell's palsy as a consequence of combination ICT and provide evidence of successful treatment of this irAE through temporary discontinuation of immunotherapy and administration of steroids.
