Head, Ears, Eyes, Nose, and Throat Flashcards
Soft contact lens user presents with severe eye pain, foreign body sensation, tearing, and photophobia.
Look for a whitish lesion on the cornea by using a penlight and/or performing a slit lamp exam and fluorescein dye test.
Caused by Pseudomonas, Staphylococcus, or Streptococcus
Can permanently impair vision because of scarring or perforation. Considered an ophthalmologic emergency. Refer to ED.
Corneal Ulcers
Acute onset of severe eye pain, photophobia, tearing, and blurred vision in one eye. Diagnosed by using fluorescein dye. A black lamp (Wood’s lamp) is used to search for fernlike lines (branching curved lines) in the corneal surface.
Infection permanently damages corneal epithelium, which may result in corneal blindness.
Herpes Keratitis
Caused by herpes simplex or herpes varicella zoster (shingles).
Avoid steroid ophthalmic drops for herpes keratitis.
Refer to ED/Ophthalmologist
Elderly patient with acute onset of severe eye pain accompanied by headache, nausea/vomiting, halos around lights, lacrimation, and decreased vision.
Examination reveals a mid-dilated pupil(s) that is oval shaped. The cornea appears cloudy. Funduscopic examination reveals cupping of the optic nerve.
Acute Angle-Closure Glaucoma
Considered an ophthalmologic emergency → refer to ED
Common with Multiple Sclerosis (MS). Loss of visual acuity over hours to days. Color vision is affected, and a central scotoma (blind spot central vision) is common.
May be accompanied by other neurologic symptoms (e.g., aphasia, paresthesia, abnormal gait, spasticity). Complains of daily fatigue on awakening that worsens as the day goes on. Higher-than-normal temperature will worsen symptoms (Uhthoff phenomenon). Has recurrent episodes.
Optic Neuritis
Refer to neurologist
Sudden onset of floaters (or increase in floaters) associated with “looking through the curtain” sensation with sudden flashes of light (photopsia). Central vision may be intact or lost.
Retinal Detachment
Refer to ED.
Patient in their 50s to 60s presents with unilateral hearing loss (sensorineural) and tinnitus, which has been present for about 3 to 4 years. Complains of unsteadiness while walking and episodes of veering or tilting that can fluctuate in severity. More common in Asians. Caused by tumor of the acoustic nerve (CN VIII). If facial nerve (CN VII) involved, may have facial paresis and paresthesias.
Acoustic Neuroma (Vestibular Schwannoma) Refer to neurologist.
Patient complains of hearing loss and intermittent ear discharge (otorrhea) from one ear that is purulent and foul smelling. On examination, there is perforation of the tympanic membrane (TM) on the superior quadrant and a cauliflower-like or pearly-white mass.
Another presentation is an intact TM with missing landmarks with the white mass visible behind the TM. Tympanogram will be abnormal (straight line). History of chronic or recurrent otitis media infection.
Cholesteatoma
Mass is not cancerous, but can erode into the bones of the face and damage the facial nerve (CN VII). Treat with antibiotics and surgical excision and repair. Refer to otolaryngologist
Parietal bone is most fractured. Linear fracture most common, followed by depressed and basilar skull fractures. Causes in adults include falls, assaults, car collisions, and penetrating missiles.
“Raccoon eyes” (periorbital ecchymosis) and bruising behind the ear (mastoid area) appear about 1 to 3 days after trauma. Physical exam (after trauma) does not show these two clinical signs immediately.
Search for a clear, golden serous discharge from the ear or nose (cerebrospinal fluid), which is also found in up to 20% of temporal bone fractures. Another common finding is hemotympanum (blue to purple color of the TM), which is caused by blood inside the middle ear.
Battle Sign (Basilar Skull Fracture) Findings of the Battle sign, raccoon eyes, hemotympanum, and otorrhea/rhinorrhea are highly suggestive of a serious head injury. Additional clinical findings are determined by brain hemorrhage, brain injury, and/or CN injury. Refer to ED.
If a young child, determine if it is primary tooth (baby tooth); if yes, do not reimplant. If permanent tooth, avoid touching root, and handle only the crown. Rinse tooth in normal saline; irrigate socket with normal saline and reimplant tooth. Afterward, have patient bite down on gauze. Store tooth in cool milk or saline, or store inside cheek (buccal sulcus) if unable to reimplant.
Avulsed Tooth
Considered a dental emergency – the sooner the avulsed tooth is reimplanted, the better the outcome. Refer to dentist as soon as possible.
Serious deep-neck infection, and it is a rare complication of tonsillitis. Severe sore throat and difficulty swallowing, odynophagia (pain on swallowing), trismus (jaw muscle spasm making it difficult to open mouth), and a “hot potato” voice. Unilateral swelling of the peritonsillar area and soft palate. Affected area is markedly swollen and appears as a bulging red mass with the uvula displaced away from the mass. Accompanied by malaise, fever, and chills.
Peritonsillar Abscess (quinsy) Assess for airway obstruction. About half of cases occur in children and adolescents. Refer to ED or call 911.
An enlarged and hard left-sided supraclavicular node(s) that is associated with malignancy, especially in adults age 40 years or older. Highly suggestive of cancers of the stomach, colon, pancreas, gallbladder, kidneys, ovaries, testicles, prostate, or lymphoid tissue. The left supraclavicular lymph node drains via the thoracic duct, abdomen, and thorax.
Virchow’s Node (Troisier’s Sign/Node) or Sentinel
Workup includes a thorough history, physical exam, laboratory testing, and imaging. Refer to surgeon for a biopsy.
Inflammation of the edges of the eyelids where the eyelashes grow (hair follicles). The tiny oil glands at the base of the eyelashes become clogged (meibomian glands).
Patient complains of itching or irritation in the eyelids (upper/lower or both), gritty sensation, eye redness, and crusting. Small scales like dandruff may be present.
Lid may be colonized by staphylococcal bacteria. Intermittent exacerbations. May be associated with dandruff, seborrheic dermatitis, or rosacea.
Blepharitis
Johnson’s Baby Shampoo with warm water: Gently scrub eyelid margins until resolves. Consider topical antibiotic solution (erythromycin eye drops) to eyelids two or three times/day (lid hygiene). Commercial eyelid scrub products are available.
Warm compress to eyelids two to four times/day during exacerbations to soften debris and relieve itching.
Age-related visual change due to a decreased ability of the eye to accommodate and focus due to stiffening of the lenses; usually starts at the age of 40 years; near vision is affected with decreased ability to read small print at close range.
Presbyopia
Fundi: The veins are larger than arteries; veins are darker (in color) than arteries.
Cones: For color perception, sharpest vision (20/20 vision).
Rods: For low-light vision (night vision), peripheral vision.
Macula (and fovea): Responsible for our central vision, sharpest vision (20/20 vision), and color vision. The center of the macula is called the fovea. It contains large numbers of cones. Diseases of the macula cause a loss of central vision.
Eye Examination
Bones (ossicles) of the ear: Malleus, incus, and stapes. The stapes is the smallest bone in the body.
TM: Appears as translucent off-white to gray color with the “cone of light” intact. The lateral process of the malleus is located at the upper quadrant of the TM and lies in front of the pars flaccida. The pars tensa is located on the lower aspect and appears to bulge slightly. It is the area of the TM where the cone of light is visible.
Tympanogram: This is the most objective measure to test for presence of fluid inside middle ear
Pinna: Has a large amount of cartilage. Blunt trauma can result in a hematoma, which should be drained as soon as possible to avoid damage to the cartilage of the ear. If untreated, it can result in cauliflower ear.
Tragus: A small cartilage flap of tissue on the front of the ear.
Cartilage: Found on the nose and ears. Does not regenerate. Refer injuries to plastic surgeon.
Cerumen: Ear wax; the color can range from yellow to dark brown.
Ears Examination
Kiesselbach’s plexus: a vascular network formed by five arteries that supply oxygenated blood to the nasal septum. Located on the anterior inferior aspect of the nose (lower one-third). An anterior nosebleed is the result if the area is traumatized.
Turbinates: Only the inferior nasal turbinates are usually visible. The medial and superior turbinates are not visible without special instruments. Bluish, pale, and/or boggy nasal turbinates are seen in allergic rhinitis.
Cartilage: Lower third of the nose is cartilage. Cartilage tissue does not regenerate.
Septum: Perforation of the nasal septum can result from inhalation of cocaine, which is a potent vasoconstrictor. Refer to plastic surgeon for repa
Nose Examination
Sinuses are air-filled cavities in the skull. There are four types:
Ethmoid and maxillary (both present at birth)
Frontal (age 5 years)
Sphenoid (age 12 years).
By age 12 years, a child’s sinuses are nearly at adult proportions.
Sinuses Examination
Mucous membranes are pink to dark pink and moist. Look for ulcers, fissures, leukoplakia, and inflammation. If gums are red and swollen, the patient may have gingivitis (gums may bleed when brushing teeth) or be taking phenytoin (Dilantin) for seizures (gingival hyperplasia). The tongue should not be red or swollen (glossitis). Vermilion border is at the edges of the lips. The corners of the lips are called the oral commissures. A normal adult has 32 teeth.
Mouth Examination
White-to-light-gray patch that appears on tongue, floor of mouth, or inside cheek. Caused by chronic irritation, such as from chewing tobacco or snuff.
Leukoplakia
Rule out oral cancer. Chewing or smoking tobacco, alcohol abuse, and human papillomavirus (HPV) are risk factors for oral cancer. Refer to oral surgeon for biopsy..
There are three salivary glands: parotid, submandibular, and sublingual.
Glands may become infected (sialadenitis, sialadenosis, mumps) or can become blocked with calculi (“stone”; sialolithiasis).
Salivary Glands Examination
Also known as the palatine tonsils; tonsils are made up of lymphoid tissue. Butterfly-shaped glands with small pore-like openings that may secrete thick white exudate (mononucleosis) or purulent exudate that is a yellow-to-green color (strep throat).
Tonsils Examination
Look for postnasal drip (acute sinusitis, allergic rhinitis). Lying supine worsens a postnasal drip cough. Chronic sinusitis can cause a chronic cough.
Retropharyngeal lymph nodes that are mildly enlarged and distributed evenly on the back of the throat (allergies, allergic rhinitis).
Hard palate: Look for any openings (cleft palate), ulcers, redness.
Uvula: Should be in midline position; is displaced if infected and abscessed (peritonsillar abscess).
Posterior Pharynx Examination
Anterior cervical nodes (superficial chain) drain the lymph from the skin and superficial surfaces of the anterior neck – can become enlarged with viral or bacterial infections (strep throat).
Posterior cervical nodes (superficial chain) drain the scalp, neck, and skin of the upper thoracic area. Mononucleosis can cause posterior cervical lymphadenopathy.
Lymph Nodes Examination
Mucosal lining inside eyelids
Palpebral conjunctiva
