Disorders of the Ear, Nose, Throat & Mouth Chapter 11 Pathology EARS Otitis Externa- a painful inflammation of the membranous lining of the auditory canal and/or contiguous structures. Refers to acute and chronic inflammatory process It may be diffuse or localized Is largely benign and self-limiting Invasive otitis externa is a potentially life threatneing situation EARS OE continued Epidemiology 10-20% more common in the summer months Patho- inflammation is most commonly caused by microbial infection. Colonization of the external ear is prevented immune and anatomic mechanisms EARS Management and Treatments Pain meds Heat or ice Keep dry- no swimming for 7 days Treatment for basic OE Irrigation if indicated Pain drops Antibiotic drops Ciprodex, Floxin Cortisporin May need a wick if very swollen EARS Otitis Media- OM- inflammation of the structures in the middle ear. Otitis media with effusion –OME involves the transudation of plasma from middle ear blood vessels leading to chronic fluid; this can be chronic Acute Otitis Media-AOM is infection in the middle ear EARS OM Epidemiology Accounts for 2-3% of all family practice office visits. Number of visits increases in the winter. More common in colder weather and in children. Contributing factors include; allergies, rhinitis, pharyngitis due to swelling of upper airway membranes. Most common factor is upper airway infections (colds), caused by many different viruses. Influenza, RSV, pneumovirus, adenovirus EARS OME symptoms Stuffiness, fullness, decreased hearing, pain is rare, may have popping. Rarely vertigo Usually a history of recent URI, allergies Rhinitis Rhinitis or coryza –inflammation of the nasal mucosa with congestion, rhinorrhea, sneezing, pruritus, post nasal drip Allergic Seasonal or perennial Nonallergic Infectious, irritant related, vasomotor, hormone-related, associated with medication, or atrophic May be chronic or acute Most common types Viral Perennial (hay fever) Rhinitis Epidemiology/Causes Actual prevalence is undocumented, but is very common Occurs at least as much as the common cold Estimated 40-50 million American adults suffer Seasonal allergic rhinitis parallels pollen production fall/spring Allergy occurs in all age groups Most common in adults 30-40 years Non allergic rhinitis may be acute or chronic Chronic maybe associated with bacterial sinusitis Rhinitis Rhinitis – symptoms Viral-malaise, HA, substernal tightness, rare fever, sneezing and coughing Allergic-itching of all upper air way mucosa, watery eyes, sore throat, sneezing, coughing Vasomotor-watery nasal discharge, nasal speech, mouth breathing, nasal obstruction that switches sides Rhinitis Treatments Allergic rhinitis Avoid the triggers Antihistamines Allegra, Claritin, Clarinex, Zyrtec, Astelin Nasal steroids Flonase, Nasonex, Nasacort Leukotriene receptor antagonists Singular Desensitizing immunotherapy Atrophic- bacitracin to nares, saline, irrigation Sinusitis Sinusitis is an inflammation of the mucous membranes of one or more of the paranasal sinuses; frontal, sphenoid, posterior ethmoid, anterior ethmoid, and maxillary Acute-abrupt onset of infection and post-therapeutic resolution lasting no more than four weeks Subacute with a purulent nasal discharge persist despite therapy, lasting 4-12 weeks Chronic, with episodes of prolonged inflammation with repeated or inadequately treated acute infection lasting greater than 12 consecutive weeks Sinusitis Clinical presentation Gradual onset of symptoms Pain over the affected sinus, with increasing pain Pain is worse with coughing Area of pain corresponds the sinus affected Develop over at least 2 weeks of URI symptoms Nasal congestion, runny nose, pressure, cough, sore throat, eye pain, malaise, and fatigue, headache, cough, fever Sinusitis Sinusitis Management Usually viral Supportive care is most helpful Sinus rinse Few meds are helpful Sudafed, nasal spray, expectorants, Rarely use steroids or antihistamines Localized sinus infections are self limited Sinusitis Sinusitis patient education Should focus on the worsening of symptoms Avoid all contributing factors Smoke, allergens, antihistamine Increase fluids Pharyngitis Pharyngitis and tonsillitis are generalized inflammatory process of both infectious and non infectious etiology Most cases are viral and self-limiting Most cases of pharyngitis are contagious All cases of tonsillitis are contagious Pharyngitis Testing Viral throat swab cultures are used to detect herpes virus as well other viral infections… Tzanck smear of a exudate is used to detect HSV, and herpes zoster Blood test may be used for viruses HSV, EBV, CMV Candida – KOH potassium hydroxide- looking for hyphal yeast Mono spot for mono CBC for infectious pharyngitis X-ray may be needed to assess for abscess Pharyngitis Management depends on the cause Home care with symptom management Antibiotics for bacterial causes Diflucan, nystatin Be sure and assess immune status if no known cause is found Viral illnesses See therapeutics handout Antifungal for candida Voice rest, humidification, saline, viscous Xylocaine, gargles, cool mist, lozenges, sprays, Acetaminophen, codeine, warm compresses for lymph nodes May use antivirals in some cases- IE; Flu- use Tamiflu Abscess- hospital IV antibiotics and maybe surgery Temporomandibular Joint (TMJ) Disease TMJ is a collective term that refers to disorders affecting the masticatory musculature and associated structures. Sometimes know as temporomandibular disorder. TMD is a cluster or related disorder that have many features in common. The most common is pain in the muscles of mastication, the preauricular and the TMJ Is a sub classification of musculoskeletal disorder Temporomandibular Joint (TMJ) Disease Epidemiology 75% of people have at least one sign of joint dysfunction and 33% have at least one symptom, like face pain Only about 5% are in need of treatment Differentiate contributing factors Predisposing factors- increase the risk Initiating factors- cause the onset Perpetuating factors- interfere with healing Temporomandibular Joint (TMJ) Disease Symptoms Pain in the preauricular area/or TMJ Pain, jaw noise, ear symptoms, rarely jaw dislocation Chewing aggravates Pain in face or head Dull pain in temple are Tinnitus Sinus symptoms FB sensation in ear canal Decreased hearing Neck or shoulder pain Visual disturbance Limited jaw opening Jaw popping Temporomandibular Joint (TMJ) Disease Questionnaires for screening- Example questions Do your jaws make noise Does using your jaw cause you pain Have you had jaw joint problems before Does you jaw ever get stuck Is opening your mouth difficult or cause pain With ringing in the ear does opening or closing you mouth change the sound Do you have frequent headaches, neck aches, or tooth aches Temporomandibular Joint (TMJ) Disease Physical finding Complete exam to exclude other problems Observation of gait, balance, unusual habits Palpate the muscles of mastication using bimanual technique Start with the mouth closed then open Temporomandibular Joint (TMJ) Disease Management Involves understanding and treating the whole patient Goals for management- reduction of pain, restorations of acceptable function Initial TX designed to be palliative and promote healing, with selfhelp techniques and pharmacotherapy Adjustment of diet Education and alteration of oral habits (gum chewing) ICE/ HEAT Medications such as pain meds, anti-inflammatory meds, injection of trigger points Most care will be given by the specialist TMJ Follow up and referral Refer to a specialist is best idea for real TMJ disease Gingivitis Inflammation of the gingiva It may be characterized by edema, erythema, bleeding, and occasionally pain Gingivitis is usually reversible with appropriate therapy Periodontitis An inflammatory disease of the supporting tissues of the teeth caused by specific microorganisms or groups of specific microorganisms, resulting in progressive destruction of the periodontal ligament and alveolar bone with pocket formation, recession, or both.
