The facial nerve (the labyrinthine segment) is the seventh cranial nerve, or simply CN VII. It emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue See the written guide alongside the video here https://geekymedics.com/cranial-nerve-exam/Download the app here: https://geekymedics.com/geeky-medics-app/ ?..

Facial nerve paralysis is a common problem that involves the paralysis of any structures innervated by the facial nerve.The pathway of the facial nerve is long and relatively convoluted, so there are a number of causes that may result in facial nerve paralysis. The most common is Bell's palsy, a disease of unknown cause that may only be diagnosed by exclusion of identifiable serious causes Bell's palsy is an idiopathic lower motor neurone (LMN) facial nerve paralysis that accounts for most new cases (incidence 10-40/100 000 population each year).3 7 However, 30-41% of patients with LMN facial nerve weakness will have another cause that requires specific management and is often associated with a poorer prognosis.2 3 In facial paralysis, as in most medical problems, history and physical examination usually provide more useful information than laboratory tests. Sometimes, however, a more objective evaluation of facial nerve function is indicated to detect a facial nerve lesion; to measure its severity; to localize it to a particular intracranial.

The facial nerve also has a parasympathetic component which sends fibres to the submandibular, sublingual and lacrimal glands. Test procedure: Facing the patient, the practitioner instructs the patient to go through a series of facial movements (grimaces). Instruct the patient to raise their eyebrows, frown, close their eyes lightly and have. Facial nerve palsy can be either UMN type or LMN type. It can be unilateral or bilateral. The most common scenario would be LMN type unilateral facial nerve palsy (Bell's Palsy) you would encounter at the exam.LMN lesions affect both upper & lower parts of the face in contrast to the UMN lesions.. You should be thanking your destiny if you got Bell's palsy as one of your cases at the exam. Facial nerve [VII] The facial nerve has both a sensory and motor component. Ask the patient if they have had any change in their taste sensation. This tests both [VII] and [IX]. The facial nerve supplies taste fibres to the anterior 2/3 of the tongue whilst the glossopharyngeal nerve supplies taste fibres to the posterior 1/3

VII Facial Nerve - Taste. Although taste is not typically assessed during a routine neurological examination, the 7th nerve does supply taste to the anterior two-thirds of the tongue and hard and soft palates. This can be tested using salty, bitter, sour or sweet solutions Confirm that all facial nerve branches are involved diffusely (with particular reference to the muscles of the upper half of the face, which are spared in upper motor neuron lesions). Perform a thorough neurological examination (rest of cranial nerves, peripheral power, tone, reflexes and coordination) Facial nerve neuromas in the IAC may be recognized during surgery for what was presumed to be an acoustic tumor. 33 Tumor in the labyrinthine fallopian canal and the course of the facial nerve over the posterior aspect of an acoustic tumor are clues to the existence of a facial nerve neuroma. Preoperatively, we counsel patients with acoustic tumors about this unlikely possibility T he facial nerve (cranial nerve [CN] VII) is a frequently over-looked structure on imaging ex-aminations. Knowledge of the normal anatomy, embryology, and spectrum of abnormality will aid radiologists in cor-rectly diagnosing lesions of the facial nerve. In this article, we review normal facial nerve anatomy, clinical presentations, imaging ap

Examination of Cranial Nerves Anatomy and function: There are twelve pairs of cranial nerves. Cranial nerve I is a fiber tract emerging from the brain directly, while cranial nerves II through XII arise from the diencephalon and brain stem This is testing both the optic nerve (afferent pathway) and the oculomotor nerve (efferent pathway), as the response is dependent upon appreciation of light and the motor response of the muscles of the iris. There is also a consensual response in that the contralateral pupil will also respond but less markedly Facial nerve paralysis may also interfere with eating and talking. Facial nerve paralysis can be congenital, meaning a person is born with it. But most of the time, the condition occurs in adults as the result of damage to the facial nerves. One of the most common causes is Bell's palsy look for ptosis, proptosis, pupillary inequality, skew deviation of the eyes, facial asymmetry - these features should be seen when examining individual cranial nerves; look at skin for neurofibromas and scalp for craniotomy scars; look for cutaneous angiomas on the face (seen in Sturge-Weber syndrome Idiopathic facial nerve palsy is sudden, unilateral peripheral facial nerve palsy. Symptoms of facial nerve palsy are hemifacial paresis of the upper and lower face. Tests (eg, chest x-ray, serum angiotensin-converting enzyme [ACE] level, tests for Lyme disease, serum glucose) are done to diagnose treatable causes

Tear tests: The loss of the ability to form tears may help to locate the site and severity of a facial nerve lesion. Taste tests: The loss of taste in the front of the tongue may help locate the site and severity of a facial nerve lesion. Salivation test: Decreased flow of saliva may help locate the site and severity of a facial nerve lesion Examination. The facial nerve provides innervation for the muscles of facial expression. Close observation of a patient's face can yield the initial clues of asymmetrical expression (e.g., flattening of the nasolabial groove) in a patient with facial nerve palsy. The upper part of the face is relatively spared in facial paresis of an upper. The 7th (facial) cranial nerve is evaluated by checking for hemifacial weakness. Asymmetry of facial movements is often more obvious during spontaneous conversation, especially when the patient smiles or, if obtunded, grimaces at a noxious stimulus; on the weakened side, the nasolabial fold is depressed and the palpebral fissure is widened This gradient of facial weakness on the right side of the Pt's face indicates a lesion of the right/ left facial nerve or the right/ left corticobulbar tract. (left corticobulbar tract) b. The Pt shown in Fig. 6-8 had a UMN facial palsy after an occlusion of her left middle cerebral artery had caused infarction of her left cerebral hemisphere

Cranial nerves have several functions that are crucial for performing activities of daily living, if a patient has a disorder affecting cranial nerve function, you will need to identify which nerves are affected by performing a cranial nerve examination. All 12 pairs of cranial nerves may not nee The Trigeminal Nerve (V) Assess Facial Sensation; Using a piece of cotton wool, lightly touch the patient's face over the three trigeminal areas of innervation, moving from side to side. Ask the patient if there is any area that is numb or has altered sensation in any way. Loss of sensation in the distribution of a single branch suggests a peripheral nerve lesion (V1 / V2 / V3), while complete loss of sensation on one side suggests a CNS lesion Examination of facial nerve motor functions centers on assessment of the actions of the muscles of facial expression. A great deal can be learned from simple inspection. At rest the face is generally symmetric, at least in young individuals. With aging, the development of character lines may cause asymmetry that does not indicate disease Autonomic Nerve Examination. Evaluating the pupillary accommodation to light as part of the third cranial nerve examination also tests the parasympathetic functioning of the oculomotor nerve. The autonomic function of the facial and glossopharyngeal nerves is evaluated by the presence of lacrimation and salivation
