Seventh (Facial) Cranial Nerve, Neuritis C&P Exam Prep

Facial Motor Function Assessment (House-Brackmann Scale or equivalent)

What it measures: The degree of facial muscle weakness or paralysis affecting the forehead, eye closure, nasolabial fold, and mouth. Grades range from normal (Grade I) to complete paralysis (Grade VI).

What to expect: The examiner will ask you to raise your eyebrows, wrinkle your forehead, close your eyes as tightly as possible, smile broadly, puff out your cheeks, and pucker your lips. They will observe and score symmetry and strength on the affected side compared to the unaffected side.

Pain considerations: If facial movement causes or worsens pain, clearly state this to the examiner so it is documented. Pain during function may affect the rating of functional impairment.

Eyelid Closure and Corneal Protection Test

What it measures: Whether the affected eye can close completely, protecting the cornea. Incomplete closure (lagophthalmos) is a clinically significant finding that indicates moderate to severe motor involvement.

What to expect: The examiner will observe whether your eye closes completely when you blink and when you squeeze your eye shut forcefully. They may also check for Bell's phenomenon (upward eye roll on attempted closure) as a protective mechanism.

Pain considerations: Eye irritation, dryness, or pain from incomplete closure should be described in detail, including frequency and impact on daily activities such as driving, reading, or working in front of screens.

Taste Sensation Testing (Anterior Two-Thirds of Tongue)

What it measures: Integrity of the chorda tympani branch of the facial nerve, which carries taste sensation from the front two-thirds of the tongue. Loss or alteration of taste is a sensory indicator of facial nerve damage.

What to expect: The examiner may apply sweet, salty, sour, or bitter substances to the front of your tongue while your tongue is extended, asking you to identify the taste without drawing the tongue back into your mouth.

Pain considerations: Not directly applicable to taste testing, but note any pain or discomfort in the ear or jaw associated with taste changes, as these may indicate involvement of the chorda tympani and nearby structures.

Lacrimation and Salivation Assessment

What it measures: Autonomic function of the facial nerve, specifically tear production (greater petrosal nerve branch) and saliva production (chorda tympani branch). Both decreased and increased production are abnormal findings.

What to expect: The examiner will ask you about dry eye symptoms, excessive tearing, dry mouth, or drooling. They may perform a Schirmer test for tear production. The DBQ specifically captures whether you have decreased or increased salivation.

Pain considerations: Dry eye can cause significant chronic ocular pain and discomfort. Describe the severity and frequency of this pain and how it limits your daily activities.

Electrodiagnostic Studies Review (EMG/Nerve Conduction Velocity)

What it measures: Objective electrical evidence of facial nerve axonal loss, demyelination, or denervation of facial muscles. These studies are critical for distinguishing the degree of nerve damage and supporting the clinical examination findings.

What to expect: The examiner will review any existing EMG or nerve conduction study results in your records. They may order new studies if none exist or if existing studies are outdated. The DBQ has dedicated fields for documenting diagnostic test results.

Pain considerations: EMG testing itself can be uncomfortable. If you experienced significant pain or difficulty during prior electrodiagnostic studies, this context may be relevant to your overall pain profile.

100%

Complete paralysis of the seventh cranial nerve. No discernible voluntary movement of any facial muscles on the affected side. This rating level is not achievable under neuritis (DC 8307) per 38 CFR 4.123; neuritis is capped at the severe incomplete paralysis level.

From 38 CFR: Under 38 CFR 4.124a, complete paralysis represents the absolute maximum evaluation for the facial nerve. For neuritis (DC 8307), this rating is not assignable; neuritis is capped at severe incomplete paralysis per 38 CFR 4.123.

80%

Severe incomplete paralysis - the maximum rating assignable for neuritis under DC 8307 per 38 CFR 4.123. Marked loss of function with only slight movement detectable, organic changes present (loss of reflexes, muscle atrophy, constant pain, sensory disturbances).

From 38 CFR: 38 CFR 4.123 specifies that neuritis characterized by organic changes (loss of reflexes, muscle atrophy, sensory disturbances, constant pain) is rated on the scale provided for injury of the nerve, with the maximum being severe incomplete paralysis. This is the ceiling for DC 8307.

60%

Moderately severe incomplete paralysis. Significant loss of motor function, obvious facial weakness and asymmetry, but some voluntary movement preserved. Multiple organic changes present. (Note: This level is applicable to the general paralysis schedule; for neuritis, the cap is severe incomplete paralysis.)

From 38 CFR: This evaluation level reflects substantial motor and sensory impairment. Multiple organic changes (reflex loss, sensory disturbance, pain, atrophy) are expected. For neuritis without all organic changes specified in 38 CFR 4.123, moderate is the maximum assignable rating.

40%

Moderate incomplete paralysis. Obvious weakness but not disfiguring; some voluntary movement present in all muscle groups, though clearly reduced. This is the maximum evaluation for neuritis not characterized by the organic changes referenced in 38 CFR 4.123.

From 38 CFR: Per M21-1 guidance, moderate is the maximum rating for neuritis not characterized by organic changes (38 CFR 4.123). The moderate level is also the maximum for sensory-only impairment in the most significant and disabling cases.

20%

Mild incomplete paralysis. Slight weakness noticeable only on close inspection or with specific facial movements. Sensory symptoms may be present but are recurrent rather than constant and affect a limited distribution.

From 38 CFR: Per M21-1 guidance, the mild evaluation is appropriate when sensory symptoms are recurrent but not continuous, graded as lower medical impairment, and affecting a smaller area in the nerve distribution. Sensory-only impairment is rated mild or at most moderate per 38 CFR 4.124a.

Facial Muscle Weakness and Motor Deficit

How to describe it: Describe which specific facial movements are affected, how severely, and how this has changed over time. Use concrete functional examples: 'I cannot fully close my left eye, which causes constant dryness and irritation.' 'When I try to smile, only one side of my face moves.' 'My left cheek droops and I bite the inside of my cheek when chewing.' Focus on your current worst-day function, not your best day.

Example: On my worst days, my entire left side of my face is completely limp. I cannot close my eye at all and must tape it shut to sleep. I cannot form a full smile, whistle, or blow out candles. My speech is slurred because I cannot control my lips properly, and food and liquid escape from the corner of my mouth when I eat.

Examiner listens for: Specific muscle group involvement, degree of functional limitation, whether deficits are improving or worsening, whether weakness is constant or fluctuating, impact on eating, speaking, sleeping, and personal appearance.

Avoid: Do not say 'it's getting better' if you still have significant symptoms on bad days. Do not minimize the emotional and social impact of visible facial disfigurement. Do not fail to mention that your function varies - the VA rates based on the full picture including your worst days.

Pain - Constant, Intermittent, or Dull

How to describe it: The DBQ specifically captures three pain types: constant pain (at times excruciating), intermittent pain, and dull pain. Describe which type applies to you, where the pain is located (ear, jaw, face, behind eye), how severe it is on a 0-10 scale on a typical day and on your worst day, how long episodes last, and what triggers or worsens the pain.

Example: On my worst days, I have a deep, burning, constant pain starting behind my right ear that radiates across my entire right cheek and jaw. The pain reaches 8 or 9 out of 10 and makes it impossible to concentrate at work, eat comfortably, or sleep. Cold weather, stress, and fatigue reliably trigger these severe episodes.

Examiner listens for: Pain type (constant vs. intermittent vs. dull), location in the nerve distribution, severity, triggers, how pain affects sleep, work, and daily activities, and whether pain is accompanied by other organic changes.

Avoid: Do not report only your average pain level. State your worst-day pain clearly. Do not omit pain that exists behind the ear or in the jaw - this is characteristic of facial nerve neuritis and is clinically significant.

Sensory Disturbances (Numbness, Paresthesias, Dysesthesias)

How to describe it: Describe exactly where you feel numbness, tingling, burning, or abnormal sensations on your face, including whether these sensations are constant or come and go. Specify the affected region (forehead, cheek, around the eye, ear, chin, inside the mouth) and how severely these sensations interfere with your daily life.

Example: On my worst days, the entire left side of my face from my ear to my chin feels like it is simultaneously numb and burning, as if someone pressed a hot and cold object against my skin at the same time. This makes shaving, washing my face, wearing glasses, and eating very uncomfortable. It also makes it hard to tell if food is too hot before I put it in my mouth.

Examiner listens for: Location and distribution of sensory changes within the facial nerve territory, whether sensory symptoms are the only deficit or are combined with motor changes, continuity of symptoms, and impact on safety and daily function.

Avoid: Do not fail to mention if you have accidentally burned yourself or bitten your cheek because you could not feel properly. Do not describe sensory symptoms as just 'tingling' - use precise language about burning, electrical sensations, coldness, or hypersensitivity to touch.

Autonomic Symptoms (Salivation, Lacrimation, Gastrointestinal)

How to describe it: The DBQ specifically captures changes in salivation (increased or decreased), difficulty swallowing, and gastrointestinal symptoms. Describe whether you have a dry mouth, excessive drooling, dry eye, excessive tearing, or crocodile tears (tearing while eating). Explain how these symptoms affect your daily life.

Example: On my worst days, my affected eye is so dry that it is painful and red all day, and I have to use artificial tear drops every hour. I also drool involuntarily from the left side of my mouth, especially when eating or speaking, which is embarrassing in social and professional settings. I have developed crocodile tears - I cry from my affected eye when eating, which is distressing and disabling.

Examiner listens for: Evidence of chorda tympani, greater petrosal nerve, or vagal involvement through salivation and lacrimation changes; whether these symptoms are accompanied by functional consequences such as corneal damage, dehydration, or social impairment.

Avoid: Do not omit drooling or dry eye symptoms because they seem minor. These are documented DBQ fields that directly reflect the degree of nerve damage. Do not underestimate the social and occupational impact of visible drooling.

Functional Impact on Speech, Chewing, and Swallowing

How to describe it: Describe specifically how your facial nerve condition affects your ability to speak clearly, chew food on both sides, and swallow. Note whether you avoid certain foods, have changed your diet, or need extra time to eat. Describe any incidents where food or liquid escaped your mouth unexpectedly.

Example: On my worst days, my speech is noticeably slurred and people ask me to repeat myself frequently. I can only chew on one side of my mouth, which causes jaw pain and limits what I can eat. I have stopped eating in public because food falls out of my mouth uncontrollably. I sometimes choke on liquids because I cannot fully seal my lips around a cup.

Examiner listens for: Objective speech abnormalities audible during the exam, reports of dietary restriction or avoidance, evidence of aspiration risk from swallowing difficulty, and social isolation or occupational limitation from communication deficits.

Avoid: Do not say 'I manage fine' if you have significantly changed your diet or eating habits. Do not omit that you have had choking episodes or been embarrassed in social eating situations. These are significant quality-of-life impairments relevant to your rating.

Psychological and Social Impact

How to describe it: Facial disfigurement, even when partial, has well-documented psychological consequences including depression, anxiety, social withdrawal, and occupational impact. Accurately describe how the visible symptoms of your condition affect your self-esteem, social interactions, and work performance.

Example: On my worst days, I avoid all social situations because the drooping and asymmetry of my face makes me extremely self-conscious. I have reduced my social activities significantly, avoid photographs, and have experienced depressive episodes related directly to my visible facial symptoms. My employer has noted changes in my client-facing performance.

Examiner listens for: Secondary mental health conditions (depression, anxiety, social phobia) that may be separately ratable as secondary conditions; impact on occupational functioning; degree to which the visible nature of the condition impairs social integration.

Avoid: Do not hide the emotional impact of your condition. VA raters consider functional impact holistically. If you have sought or been recommended mental health treatment related to your facial nerve condition, disclose this.
