9 Differential Diagnosis of Craniofacial Pain What is It Really??

10 COMMON THINGS OCCUR COMMONLY Common presentation of a common disorder Unusual presentation of a common disorder Common presentation of an unusual disorder Unusual presentation of an unusual disorder Rare presentation of a rare disorder

11 Craniofacial Conditions Dentoalveolar Pathology *pulpal *periodontal Odontogenic and Non-odontogenic Pathology Primary headache Temporomandibular Disorders Oral Mucous Membrane Disease Oral Manifestations of Systemic Disease Neuropathic Pain (Persistent Idiopathic Facial Pain) Trigeminal Neuralgia Postherpetic Neuralgia Burning Mouth/Tongue Disorder

12 Where do we start??

13 It is more important to know what sort of person has a disease than to know what disease a person has. Don t touch the patient state first what you see; cultivate your powers of observation Sir William Osler, M.D. When in doubt, talk to your patient and actually touch them. JJ Salerno, M.D. SJ Scrivani

14 Pain Diagnosis A cluster of symptoms and signs Pattern recognition Raymond J. Maciewicz, M.D., Ph.D.

15 Diagnostic Medical Evaluation Chief complaint History of present illness Past medical history Review of systems Physical examination Diagnostic studies Assessment/Differential diagnosis Plan

16 PAIN HISTORY Location Timing Duration Quality Intensity Radiation Exacerbates?? Alleviates?? Neurosensory abnormalities Motor deficit Autonomic findings

18 The Primary Headaches (1-4) 1. Migraine *without aura *with aura 2. Tension-type headache 3. Trigeminal autonomic cephalalgias 4. Other primary headaches

19 TACs Cluster headache Episodic cluster headache Chronic cluster headache Paroxysmal hemicrania Episodic paroxysmal hemicrania Chronic paroxysmal hemicrania (CPH) Short-lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT) Short-lasting Unilateral Neuralgiaform headache with cranial Autonomic symptoms (SUNA) Hemicrania Continua

20 The Secondary Headaches (5-12) 5. Attributed to trauma or injury to the head and/or neck 6. Attributed to cranial or cervical vascular disorder 7. Attributed to non-vascular intracranial disorder 8. Attributed to a substance or its withdrawal 9. Attributed to infection 10. Attributed to disorder of homeostasis 11. HA or facial pain attributed to disorder of cranium, neck, eyes, ears, nose, sinuses, teeth, mouth, or other facial or cranial structures 12. Attributed to psychiatric disorder

21 Red Flags in the Headache History HA accompanied by unconsciousness First-worst HA (appearing suddenly) HA accompanied with neurological abnormalities during and/or after the HA HA associated with fever or stiff neck HA developing after 50 years of age A change in characteristic response to previous treatments of HA HA associated with alterations in behavior and personality HA initiated by Valsalva maneuver

22 SNOOPP for Secondary HA David Dodick, MD Mayo Clinic, Scottsdale, AZ Systemic symptoms Secondary risk factors underlying disease Neurological symptoms or abnormal signs Onset: sudden, abrupt, or split-second ( First, Worst ) Older: new onset and progressive HA, especially in older-age group Pattern change Previous HA history: attack frequency, severity, or clinical features

23 Adapted from RA Purdy, M.D. It should be easy to separate primary and secondary headaches by diagnosis. It should be easy once this is done to perform tests to rule out the secondary headaches. Since it is not easy, what is the problem. Atypical Features Need more history and physical examination!!

24 Headache attributed to head and/or neck trauma (5.1-7) 5.1 Acute post-traumatic HA moderate or severe head injury mild head injury 5.2 Chronic post-traumatic HA 5.3 Acute HA attributed to whiplash injury 5.4 Chronic HA attributed to whiplash injury 5.5 HA attributed to traumatic intracranial hematoma 5.6 HA attributed to other head and/or neck trauma 5.7 Post-craniotomy HA

25 Postconcussion Syndrome (PCS) PCS refers to a large number of signs and symptoms that may occur alone or in combination, usually after mild head injury. Concussion is a trauma-induced alteration in mental status that may or may not involve loss of consciousness. LOC does not have to occur for PCS to develop. Headache, dizziness, blurred vision, fatigue, irritability, anxiety, insomnia, loss of concentration and memory, depression and noise sensitivity are the most common complaints.

26 Post-traumatic Headaches 30% - 90% of persons who are symptomatic after MHI. Paradoxically, HA prevalence and lifetime duration is greater in those that have MHI compared with those who have more severe head trauma. More common in those who have a history of HA. Many patients have more than 1 type of HA. Neck injuries commonly accompany head trauma and can produce HAs. HAs are commonly associated with whiplash injuries. Although not part of PCS, HAs associated with subdural and epidural hematomas also occur.

27 Whiplash-Related Injuries Possible Symptoms (1) Headache (2) Neck pain (3) Reduced cervical range of motion (4) Face and jaw pain (5) Autonomic dysfunction (6) Visual disturbances (7) Dizziness (cervical vertigo) Management depends upon the nature of the complaint Commonly seen after motor vehicle accident with associated TBI

Proprioceptive afferents from the tongue pass from the hypoglossal nerve into the ventral C2 ramus. Causes: RA of the cervical spine, congenital joint laxity, hypomobility of the contralateral lateral A-A joint

68 Headache and Facial Pain Due to Nasal and Paranasal Sinus Disease Sinus Headache

69 Odontogenic Pain Diagnosis Pulpitis Periodontal Cracked tooth Dentinal Diagnostic Features Spontaneous and/or evoked deep/diffuse pain in compromised dental pulp. Pain may be sharp, throbbing, or dull. Localized deep continuous pain in compromised periodontium (eg, gingiva, periodontal ligament) exacerbated by biting or chewing. Spontaneous or evoke brief sharp pain in a tooth with history of trauma or restorative work (eg, crown, root cannal). Brief, sharp pain evoked by different kinds of stimulus to the dentin (eg, hot or cold drinks). Diagnostic Evaluation Look for deep caries and recent or extensive dental work. Pain provoked/exacerbated by percussion, thermal or electric stimulation of affected tooth. Dental x rays helpful (periapical). Tooth percussion over compromised periodontum provokes pain.look for inflammation or abscess (eg, periodontitis, apical dental x rays helpful (bitewings, periapical). Presence of tooth fracture may be detectable by x ray. Percussion should elcit pain. Dental x rays are helpful (periapical taken from different angles). Exposed dentin or cementum due to recession of periodontum. Possible erosion of dentinal structure. Cold stimulation reproduce pain. Treatment Medication: NSAIDs, nonopiate analgesics. Dentistry: remove carious lesion, tooth restoration, endodontic treatment or tooth extraction. Medication: NSAIDs, non opiate analgesics, antibiotics, mouthwashes. Dentistry: drainage and debridement of periodontal pocket, scaling and root planning, periodontal surgery, endodontic treatment or tooth extraction. Medication: NSAIDs, nonopiate analgesics. Dentistry: depends on level of the tooth fracture restoration; treatment, or extraction of the tooth. Medication: mouthwash (fluoride), desensitizing toothpaste. Dentistry: fluoride or potassium salts, tooth restoration, endodontic treatment. Patient education, diet, tooth brushing force and frequency, proper tooth paste.

84 Headache attributed to psychiatric disorder (12.1-2) 12.1 Somatization disorder 12.2 Psychotic disorder

85 Psychological Disorders and Chronic Pain Why? 1. High prevalence of psychological comorbidities among patients with chronic pain 2. Presence of chronic pain may cause emotional distress and exacerbate premorbid psychological disorders 3. Emotional problems may increase perceived pain intensity, disability and perpetuate dysfunction 4. Unrecognized and untreated psychological distress may interfere with successful treatment of chronic pain Adapted from Turk, D.

86 Psychological Conditions Associated with Chronic Pain Mood Disorders Anxiety Disorders Somatoform Disorders Personality Disorders Other Conditions

87 Substance abuse and pain co-occur 3-19% of chronic pain patients suffer from addictive or substance abuse disorders Fishbain et al (1992) Haller & Butler (1991) Fishbain et al (1999) Rafii et al (1990) Bernt et al (1993) Chabal et al (1998) Cowan et al (2003)

109 Of 770 articles retrieved and reviewed, 10 met inclusion criteria, and nine had data on both odontogenic and nonodontogenic causes of pain. A total of 3,343 teeth were enrolled within the included studies and 1,125 had follow-up information regarding pain status. We identified 48 teeth with nonodontogenic pain and estimated a 3.4% (95% confidence interval, 1.4%-5.5%) frequency of occurrence.

110 Chronic Neuropathic Facial Pain Trigeminal Neuropathic Pain Disorder IHS Idiopathic Persistent Facial Pain Complex, multi-factorial process Regional Pain is the primary symptom Additional symptoms which occur together; the sum of signs of any morbid state - a Syndrome CRPS type I and II

111 Tolosa-Hunt Syndrome Episodic unilateral orbital or retro-orbital pain (average of 8 weeks, if untreated) Ophthalmoplegia (CN II, III, IV, VI) simultaneously or within the first 2 weeks Prompt (within 72 h) to treatment with steroids Other pathological conditions excluded with examination and neuroimaging Thought to be due to a nonspecific granulomatous inflammatory infiltrative process with no obvious specific pathological trigger in the region of the posterior superior orbital fissure, orbital apex or cavernous sinus

112 Raeder s Paratrigeminal Syndrome Paratrigeminal oculo-sympathetic syndrome (POSS) Sympathetic dysfunction (miosis, ptosis or both), but with normal forehead sweating (compared to Horner s syndrome) First division trigeminal neuropathic pain or sensory loss Anatomical localization points to the middle cranial fossa medial to the trigeminal ganglion and lateral to the anterior clinoid process Neuroimaging is necessary and important, and if negative, should be repeated over a period of time to determine if an underlying abnormality had been missed This syndrome is not specific to any pathological entity
