Treatment involves medications like carbamazepine or surgical procedures to decompress the nerve. Differential diagnoses include dental pain, sinusitis, and migraines.
This document discusses various types of neuralgia and related conditions that cause facial pain, including:
- Trigeminal neuralgia, the most common and severe form of facial nerve pain. It causes sharp, shooting pain in the face and can be triggered by minor stimuli.
- Burning mouth syndrome, which causes a burning sensation in the mouth without any detectable cause. It has no visible lesions and the exact cause is unknown.
- Auriculotemporal syndrome, a rare condition where damage to the auriculotemporal nerve leads to facial sweating during eating due to nerve regeneration.
- Bell's palsy, an idiopathic facial paralysis or weakness of the facial
Pain is an unpleasant sensory experience associated with actual or potential tissue damage. Facial pain can originate from various structures innervated by cranial nerves like the trigeminal nerve. It can be nociceptive, neuropathic, inflammatory, acute, chronic, or referred pain from other sources. A thorough history, exam of the head and neck, and diagnostic tests are needed to diagnose the underlying cause. Common conditions include dental issues, TMJ disorders, trigeminal neuralgia, post-herpetic neuralgia, migraine, cluster headaches, and psychogenic or idiopathic facial pain syndromes.

It states that adequate access requires wide mouth opening and retraction of tissues away from the surgical field. Improved access can be gained by creating surgical flaps using incisions. Key principles of incisions and flap design are outlined such as using a sharp blade, firm strokes, avoiding vital structures, and designing flaps to ensure adequate blood supply and healing. Common flap types including triangular, trapezoidal, envelope, and semilunar flaps are described. Careful handling of tissues is also emphasized to minimize damage.

Congestive Heart failure is caused by low cardiac output and high sympathetic discharge. Diuretics reduce preload, ACE inhibitors lower afterload, beta blockers reduce sympathetic activity, and digitalis has inotropic effects. Newer medications target vasodilation and myosin activation to improve heart efficiency while lowering energy requirements. Combination therapy, following an assessment of cardiac function and volume status, is the most effective strategy to heart failure care.
Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) CosmeticsMuskanShingari
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.
2. Facial Neuropathology
Although oral pain is most frequently of odontogenic origin, many
facial pains arise from other sources.
The diversity of structures in the head and neck region (e.g., eyes,
ears, salivary glands, muscle, joints, sinus membranes, intracranial
blood vessels) can make arriving at an accurate diagnosis challenging.
Toothache symptoms may occur in a healthy tooth because of
referred pain or a damaged pain transmission system.
3. Facial Neuropathology
BASICS OF PAIN NEUROPHYSIOLOGY
Pain is a complex human psychophysiologic experience.
This unpleasant experience is influenced by such factors as :-
• Past pain experiences .
• Cultural behaviors .
• Emotional and medical states.
Although the pain sensory system appears hardwired, the
psychological influences on pain perception should not be
underestimated.
All dentists are well aware of the extensive variability of the pain
response that different patients display to similar procedures.
Some patients, the sound of the dental drill evokes true pain
perception despite the fact that the bur has not yet touched the
tooth.
4. Facial Neuropathology
BASICS OF PAIN NEUROPHYSIOLOGY
Psychological influences are particularly important in determining
perceived pain intensity and patient response to pain.
When pain becomes chronic, generally defined as greater than 4 to 6
months induration, attention to psychological influences can become
particularly important .
5. Facial Neuropathology
CLASSIFICATION OF OROFACIAL PAINS
It is appropriate to classify orofacial pains as primarily somatic,
neuropathic, or psychological.
Somatic pain arises from musculoskeletal or visceral structures
interpreted through an intact pain transmission and
modulation system.
Examples of musculoskeletal pains are TMJ disorders or periodontal
pain.
Examples of visceral orofacial pains include salivary gland pain and
pain caused by dental pulpitis .
Neuropathic pain arises from damage or alteration to the pain
pathways, most commonly a peripheral nerve injury
due to surgery or trauma or involving CNS injury as in
thalamic stroke .
6. Facial Neuropathology
CLASSIFICATION OF OROFACIAL PAINS
Orofacial pains of true psychological origin are so rare as not to
be included in the differential diagnosis of orofacial pain for the
general practitioner.
A dental patient complaining of chronic pain should be presumed to
have a real pain problem unless definitively proven otherwise.
For those undiagnosed facial pains, the appropriate term should be
facial pain of unknown cause until a definitive diagnosis has been
established.
7. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Neuropathic pains arise from an injured pain transmission or
modulation system. Surgical intervention or trauma is frequently the
cause.
example, trauma to the infraorbital region may lead to numbness or
pain in the distribution of the infraorbital nerve.
Extraction of impacted mandibular third molars carries a measurable
risk of nerve damage to the mandibular and lingual nerves leads to
paresthesia, an abnormal sensation .
Dysesthesia
it is described as a burning or sharp electric shocklike
sensation.
When a patient complains of burning or sharp shocklike pain in the
face or mouth, pain of neuropathic origin should be included in the
differential diagnosis.
8. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Neuropathic pains may also give rise to the sensation of tooth pain,
which is often a diagnostic dilemma for dentists.
Referral of patients for management of these disorders to a
neurologist is customary.
9. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Trigeminal neuralgia
The prototypic neuropathic facial pain is trigeminal neuralgia (TN)
(Box 30-2), literally nerve pain arising from the trigeminal nerve.
Specific criteria of TN or tic douloureux ( painful tic) .
Occurring most frequently in patients over 50 years of age .
Incidence 8 : 100,000; female-to-male ratio 1.6 : 1 .
TN usually occurs with sharp, electric shocklike pain in the face or
mouth.
Pain is intense, lasting for brief periods of seconds to 1 minute,
followed by a refractory period during which the pain cannot be
reinitiated.
At times, a background aching or burning pain is present.
Usually, a trigger zone is present where mechanical stimuli such as
soft touch may provoke an attack.
10. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Trigeminal neuralgia
Specific criteria of TN or tic douloureux ( painful tic) .
Firm pressure to the region is generally not as provocative.
Common cutaneous trigger zones include the corner of the lips,
cheek, ala of the nose, lateral brow.
Any intraoral site may also be a trigger zone for TN, including teeth,
gingiva, or the tongue.
Sometimes a background aching pain accompanies TN, making it
difficult to distinguish from the pain of acute pulpitis or periapical
periodontitis.
Importantly, local anesthetic block of the trigger zone arrests the pain
of TN for the duration of anesthesia and sometimes longer, which can
lead the dentist to mistakenly ascribe a “dental” cause to the pain
complaint.
11. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Trigeminal neuralgia
Cause of TN is not entirely clear, but the consensus is that
pressure on the root entry zone of the trigeminal nerve by a vascular
loop leads to focal demyelination which leads to hyperactive
discharge of the nerve.
Other diseases such as multiple sclerosis, tumors, and Lyme disease
can produce pain similar to that produced by TN.
Treatment (Medical or surgical ).
Medical treatment is generally undertaken with anticonvulsants.
Classic medication for the condition is carbamazepine, but
newer anticonvulsants (e.g., gabapentin and oxcarbazepine) and
the antispastic baclofen are commonly used .
12. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Trigeminal neuralgia
Treatment (Medical or surgical ).
Many of these medications have significant, even life-threatening,
side effects; therefore, only dentists focusing on orofacial pain
diagnosis and management use them in dental practice.
Surgical treatment
Microvascular decompression of the offending vascular loop
( Janetta procedure).
GammaKnife radiosurgery .
Percutaneous needle thermal rhizotomy, or balloon compression of
the root entry zone.
Unfortunately, when the trigger zone is located in an intraoral, dental,
or periodontal site, unnecessary dental treatment is common.
13.
14. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Pretrigeminal neuralgia. (pre-TN)
The presenting condition is typically an aching dental pain in a region
where clinical and radiographic examinations reveal no abnormality.
Local anesthetic block of the tooth (or extraction site, if applicable)
arrests pain for the duration of anesthetic’s action.
A number of patients with this condition have been demonstrated to
go on to have typical TN symptoms (i.e., sharp electric shock pains
the area).
Pre-TN responds to similar treatments as TN, beginning with
anticonvulsant therapy.
15.
16. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Odontalgia resulting from deafferentation (atypical odontalgia).
Deafferentation
The freeing of a motor nerve from sensory
components by severing the dorsal root central to the dorsal ganglion.
Pain resulting from deafferentation refers to pain that occurs when
damage to the afferent pain transmission system has occurred.
This condition is caused by trauma or surgery, including extraction
and endodontic treatment.
By definition, extraction and endodontics are deafferentating
because they involve amputation of tissue that contains the nerve
supply of a human structure, the tooth.
17. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Postherpetic neuralgia (PHN)
Postherpetic neuralgia (PHN), also known as herpes zoster (HZ) .
(HZ) is the clinical manifestation of the reactivation of a lifelong
latent infection with varicella zoster virus, usually contracted after an
episode of chicken pox in early life.
HZ occurs more commonly in later life and in immunocompromised
patients.
Most cases occur in patients over 60 years of age.
Varicella zoster virus tends to be reactivated only once in a person’s
lifetime, with the incidence of second attacks being less than 5%.
PHN occurs after reactivation of the virus, which can lay dormant in
the ganglia of a peripheral nerve.
18. Postherpetic neuralgia (PHN)
Pain related to HZ commonly appears before any rash is visible.
The acute phase is painful, but subsides, along with the rash, within
2 to 5 weeks.
Pain is typically burning, aching, or shocklike (consistent with a pain
caused by a neuropathic condition).
Treatment
Anticonvulsants or tricyclic or other antidepressants.
Local injections of painful sites, sympathetic block, or both are
sometimes of value.
Most importantly, preventive treatment of PHN with antivirals,
analgesics, and frequently corticosteroids very early after rash
presentation can significantly reduce the expression of PHN.
19. A related condition, Ramsay Hunt syndrome, is a herpes zoster
infection of the sensory and motor branches of the facial nerve (VII),
and in some cases the auditory nerve (VIII).
Symptoms include facial paralysis, vertigo, deafness, and herpetic
eruption in the external auditory meatus.
The tongue can also be involved via the chorda tympani.
20. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Neuroma
After peripheral nerve transection, the proximal portion of the nerve
generally forms sprouts in an effort to regain communication with the
severed distal component.
When sprouting occurs without distal segment communication, a
stump of neuronal tissue, Schwann cells, and other neural elements
can form.
This stump, or neuroma, can become exquisitely sensitive to
mechanical and chemical stimuli.
Pain is commonly burning or shocklike.
Frequently, a positive Tinel sign is present.
In this test, tapping over the suspected neuroma produces sharp,
shooting electric shocklike pain.
21. NEUROPATHIC FACIAL PAINS
Neuroma
Damage to the mandibular or lingual nerve after third molar surgery
is a source for
neuroma formation that a dentist might see.
When a patient develops a painful neuroma of the inferior alveolar or
lingual nerve or a neuroma is discovered during management of a
patient with a nerve injury, the surgeon typically resects the neuroma
and then reattaches the distal portion of the nerve back
to the proximal end.
22. Facial Neuropathology
NEUROPATHIC FACIAL PAINS
Burning mouth syndrome
Patient perceives a burning or aching sensation in all or part of the
oral cavity.
The tongue is the most frequently involved site.
Perceived dry mouth and altered taste are common.
The cause is unknown .
Most patients are postmenopausal women, although hormone
replacement therapy does not consistently improve symptoms.
Approximately 50% of patients improve without treatment over a 2-
year period .
Predominant treatment approach is with anticonvulsants or
antidepressants .
23. Facial Neuropathology
CHRONIC HEADACHE
Headache has many causes and is one of the
most common complaints encountered by the primary care physician.
Migraine
Migraine is a common headache .
Afflicting approximately 18% of woman and 8% of men.
Typically occurs in the teenage years or in young adulthood but may
begin in very young children as well.
Before puberty, migraine occurs equally in both sexes. After puberty,
the ratio changes, and women are at least twice as likely as men to
have migraines.
Migraine headaches are unilateral in approximately 40% of cases.
24. Facial Neuropathology
CHRONIC HEADACHE
Migraine
An “aura” may develop several minutes to 1 hour before headache
onset in approximately 40% of patients.
The aura
Is a neurologic disturbance, frequently expressed as flashing
or shimmering lights or a partial loss of vision.
About 80% of those suffering from migraine headaches have nausea
and photophobia (intolerance to light) during attacks.
Migraines typically last 4 to 72 hours.
Headache triggers include menstruation, stress, certain vasoactive
foods or drugs, and certain musculoskeletal disorders that produce
pain in the trigeminal system (e.g. TMJ disorders).
25. Facial Neuropathology
CHRONIC HEADACHE
Migraine
Mechanism for migraine headache, although not completely
understood, appears to involve neurogenic inflammation of
intracranial blood vessels resulting from neurotransmitter imbalance
in certain brainstem centers.
Migraine is a referred pain process, and the intracranial vessel
involved determines the site of perceived pain .
Treatment
Normalizing neurotransmitter imbalance with antidepressants,
anticonvulsants, β-blockers, cyproheptadine, botulinum toxin, and
other drugs.
For the dentist, knowledge of migraine is important because TMJ
disorders may precipitate a migraine attack in a migraine-prone
26. Facial Neuropathology
CHRONIC HEADACHE
Tension-Type Headache
Tension-type headache is common in the general population, and
most individuals have experienced tension-type headaches.
Chronic tension-type headache is more common in women than
in men.
The headache is generally bilateral.
Pain is frequently bi-temporal or frontal–temporal in distribution.
Patients commonly describe their pain as though their head is “in a
vice” or a “squeezing hatband” is around their head.
These headaches can occur with or without “pericranial muscle
tenderness” (i.e., tenderness to palpation of the masticatory and
occipital muscles).
To be defined as chronic tension-type headache, symptoms must be
present longer than 15 days per month.
27. Facial Neuropathology
CHRONIC HEADACHE
Tension-Type Headache
Psychosocial factors are often a contributing factor influencing
tension-type headache.
For the dentist, it is important to distinguish tension-type headache
from masticatory myofascial pain. ( both conditions have similar
symptoms).
It is significant that in myofascial pain, pressure to various head or
neck muscles refers to the site of head pain, whereas in tension-type
headaches, pressure identifies the site of pain.
In tensiontype headache, pain does not proportionally increase with
increasing pressure to the headache site or refer pain to other areas.
28. Facial Neuropathology
CHRONIC HEADACHE
Cluster Headache
Cluster headache is a clearly unilateral head pain typically centered
around the eye and temporal regions.
The pain is intense, frequently described as a stabbing sensation .
Headaches tend to occur in cyclical patterns or clusters,
last 15 to 180 minutes .
May occur once or multiple times per day .
Pain occur with precise regularity ( awakening the patient at the
same time night after night).
The headaches can occur in clusters such that they may be present
for some months and then remit for several months or even years.
Alcohol ingestion ,Smoking tobacco triggers headache but only
during cluster episodes.
Men are much more likely to have cluster headaches compared with
women .
29. Facial Neuropathology
CHRONIC HEADACHE
Cluster Headache
Treatment.
Is preventive or symptomatic.
Preventive treatment is accomplished with verapamil, lithium salts,
anticonvulsants, corticosteroids, and certain ergot compounds.
Symptomatic treatment is with “triptans,” ergots, and analgesics.
Oxygen inhalation at 7 to 10 liters per minute (L/min) may
be an effective .
Local anesthetics .
Dentists must be aware that cluster headache frequently produces
pain in the posterior maxilla, mimicking severe dentoalveolar pain
in the posterior maxillary teeth.
Pain is frequently stabbing and intense.
30. Facial Neuropathology
CHRONIC HEADACHE
Cluster Headache
Common features can distinguish a toothache resulting from cluster
headache from a toothache produced by a dental problem:-
• Rapid emergence and discontinuation of symptoms unlike typical
toothache
• Toothache precipitated by alcohol ingestion .
• Toothache accompanied by unilateral rhinorrhea or other
parasympathetic symptoms
• Toothache that occurs with periodicity
