This clinical photograph shows the frontal view of an elderly male patient exhibiting signs of bilateral lower motor neuron facial nerve palsy (Bell's palsy). A prominent finding is Bell's phenomenon, where the patient's eyeballs rotate upward and outward when attempting to close the eyes, leaving the sclera visible due to incomplete eyelid closure (lagophthalmos). The facial features appear relatively symmetrical but mask-like, with a loss of normal expression lines. The mouth is slightly open with evidence of drooling at the commissures, consistent with orbicularis oris muscle weakness. This presentation is highly suggestive of cranial nerve VII involvement, often associated with systemic conditions such as Guillain-Barr syndrome, sarcoidosis, or leptomeningeal metastasis. The image is an educational resource for demonstrating neurological deficits and the physical examination findings of bilateral facial paralysis.

This clinical photograph of a pediatric patient demonstrates classic features of left-sided peripheral facial nerve palsy (Bell's palsy), commonly associated with Melkersson-Rosenthal Syndrome in this context. The image illustrates significant facial asymmetry: the left eye exhibits lagophthalmos (incomplete closure) with notable scleral show (Bell's phenomenon), where the eyeball rolls upward as the patient attempts to close the eye. On the lower face, there is a distinct obliteration of the left nasolabial fold and a compensatory right-sided deviation of the labial commissure, resulting from the loss of muscle tone on the paralyzed left side. These findings represent a House-Brackmann grade 4 dysfunction. The image serves as a visual diagnostic tool for identifying lower motor neuron facial weakness, characterized by the involvement of both the upper and lower facial muscles on the affected side.

A frontal clinical photograph of an elderly female patient demonstrating symptoms of unilateral facial nerve paralysis, specifically Bell's palsy, in a pretreatment state. The image illustrates significant facial asymmetry localized to the left side. Key clinical findings include the flattening of the left forehead wrinkles, a slight drooping of the left lower eyelid (suggestive of orbicularis oculi weakness), and a pronounced drooping of the left labial commissure (mouth corner) compared to the right side. The nasolabial fold on the left appears effaced or less defined than on the right. Additional visible skin features consistent with the patient's age include solar lentigines (hyperpigmented age spots) on the cheeks and forehead, and dynamic rhytids (wrinkles) on the unaffected right side of the forehead. This visual serves as an educational example of House-Brackmann Grade V facial paralysis, where resting asymmetry is prominent and motor function is severely impaired.

This clinical photograph illustrates an elderly male patient undergoing facial rehabilitation therapy for Bell's palsy or secondary facial nerve paralysis. The patient is seated in a wheelchair within a clinical setting, characterized by green privacy curtains and a large standing mirror used for visual biofeedback. The primary focus of the image is the patient performing a facial exercise: assisted closure of the mouth. He is using his right hand to manually manipulate the right side of his lips, compensating for muscular weakness and inability to close the mouth independently. Key clinical features visible in the patient's reflection include potential right-sided facial drooping and a dressing on the dorsum of the left hand, indicating recent intravenous access or monitoring. The educational focus of this visual is the demonstration of manual facilitation techniques in neuromuscular re-education for the facial muscles. This type of intervention is common in physical or occupational therapy to address functional deficits such as drooling and difficulty chewing during recovery from lower motor neuron lesions.
