Ear, Nose, and Throat
Adapted from Mosby’s Guide to Physical Examination, 6th
Ed.Ch. 12
![Page 2: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/2.jpg)
Development
• Maxillary and ethmoid sinuses– present at birth, though very small
• Sphenoid sinus– tiny cavity at birth– not fully developed
until puberty
• Frontal sinus– develops by 7-8 years
![Page 3: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/3.jpg)
Infant
• External auditory canal is shorter and has an upward curve
• Eustachian tube is relatively wider, shorter and more horizontal
– Reflux of nasopharyngeal secretions
![Page 4: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/4.jpg)
Child
• As the child grows, the eustachian tube lengthens and its pharyngeal orifice moves inferiorly
• Growth of adenoids may occlude the eustachian tube– Interferes with aeration of the middle
ear
![Page 5: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/5.jpg)
• Salivation increases by 3 months– Drools until swallowing
is learned
![Page 6: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/6.jpg)
Teeth
20 deciduous teeth • appear between 6
and 24 months
![Page 7: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/7.jpg)
Teeth
• Eruption of permanent teeth begins about 6 years of age
• Completed ~14-15 years old
• 3rd molar (“wisdom tooth”)– 18 years old
![Page 8: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/8.jpg)
Ear, Nose, Mouth Exam
“Frequent site of congenital malformation therefore thorough
examination is important.”
![Page 9: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/9.jpg)
Inspection
• Auricle– Well formed, all landmarks present– Very flexible
• Should have instant recoil after bending
CLINCAL NOTE: Premature infant– May appear flattened with limited incurving
of the upper auricle– Slower ear recoil
![Page 10: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/10.jpg)
• The tip of the auricle should cross an imaginary line between the outer canthus of the eye and the prominent portion of the occiput (EOP)
![Page 11: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/11.jpg)
• Low or poorly shaped auricles– Associated with renal disorders and
congenital abnormalities
![Page 12: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/12.jpg)
• NO skin tags should be present
• Preauricular skin tagor preauricular pit– anterior to the tragus– remnant of 1st branchial cleft
![Page 13: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/13.jpg)
Internal Ear Exam
1. Lay the infant supine/prone2. Turn head to the side3. Hold otoscope so that the ulnar surface
of your hand rests against the infant’s head
*Prevent trauma to auditory canal
4. Other hand stabilizes infant’s head5. Pull auricle down to straighten the
canal
![Page 14: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/14.jpg)
Newborns
• Auditory canal is often obstructed with vernix (newborn)
• Tympanic membrane may be in an extremely oblique position until 1 month old
*Should be examined within the first few weeks of life
![Page 15: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/15.jpg)
In neonates, you may note…
• Limited mobility• Dullness and opacity of a pink or
red tympanic membrane• Light reflex may appear diffuse
– Tympanic membrane is not conical for several months
![Page 16: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/16.jpg)
“As the middle ear matures in the first
few months, the tympanic
membrane takes on the expected appearance.”
![Page 17: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/17.jpg)
Hearing
Use a bell, toy, voice, or clap your hands
• Make sure the infant is not responding to air movement or visual stimulus
• Remember, responses to repeated sound stimuli will diminish as the infant tunes it out
![Page 18: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/18.jpg)
Expected Hearing Response
Birth to 3 months
Startle reflex, crying, cessation of breathing or movement in response to sudden noise; quiets to parent’s voice
4 to 6 months Turns head toward source of sound but may not always recognize location of sound; responds to parent’s voice; enjoys sound producing toys
![Page 19: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/19.jpg)
Expected Hearing Response
6 to 10 months Responds to own name, telephone ringing, and person’s voice, even if not loud; begins localizing sounds above and below, turns head 45 degrees towards sound
10 to 12 months Recognizes and localizes source of sound; imitates simple words and sounds
![Page 20: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/20.jpg)
Infant Nose Exam
External Nose• Symmetric appearance• Positioned in the vertical midline on the
face– Deviation of the nose may be related to
fetal position
• Only minimal movement of the nares with breathing should be apparent
![Page 21: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/21.jpg)
Consider a possible congenital abnormality if…
• Saddle-shaped nose with a low bridge and broad base
• Short small nose• Large nose
![Page 22: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/22.jpg)
Internal nose• Inspect by shining a light inside
– Gently tilt the nose tip up with your thumb
• In infants, you may see a small amount of clear fluid discharged; crying
![Page 23: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/23.jpg)
• Nasal patency must be determined at the time of birth
– Obligatory nose breathers
Mouth closed, occlude one naris and then the other
Observe the respiratory pattern
![Page 24: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/24.jpg)
With total obstruction, the infant will not be able to inspire or expire through the noncompressed naris
Consider:• Septal deviation
– Delivery trauma
• Choanal atresia
![Page 25: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/25.jpg)
Infant Sinuses
• Maxillary and ethmod sinuses are small during infancy
• Few problems arise in these areas
• Examination is generally unnecessary
![Page 26: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/26.jpg)
Infant Mouth Exam
• Crying provides an opportunity to examine the mouth
• Avoid depressing the tongue– Stimulates a strong reflex protrusion– Makes visualization of the mouth
difficult
![Page 27: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/27.jpg)
• Well formed with no cleft
• Buccal mucosa– Pink and moist – No lesions
• NOTE: Secretions that accumulate in the newborn’s mouth may indicate esophageal atresia
![Page 28: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/28.jpg)
• Scrape any white patches with a tongue blade
– Nonadherent• milk deposits
– Adherent• candidiasis (thrush)
![Page 29: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/29.jpg)
Drooling• Normal from 6 weeks
to 6 months
• Consider a neurologic disorder if it persists >12 months
![Page 30: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/30.jpg)
Gums • Should be endentulous
– smooth with a serrated edge of tissue along the buccal margins
Teeth• Count deciduous teeth• Note any unusual sequence of eruption
![Page 31: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/31.jpg)
Tongue• fits well in the floor of the mouth• protrudes beyond the alveolar ridge
– If not, possible feeding difficulties
• Frenulum– Usually attaches midway between the
ventral surface of the tongue and its tip
![Page 32: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/32.jpg)
• Insert your finger into the infant’s mouth– Fingerpad to the
roof of the mouth
Evaluate the infant’s suckPalpate the hard and soft palatesStimulate a gag reflex by touching
the tonsillar pillars
![Page 33: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/33.jpg)
Normally…
• Should have a strong suck– Tongue pushing vigorously upward against
the finger
• Palatal arch should be dome shaped• Neither hard nor soft palate should have
palpable clefts• Soft palate should rise symmetrically
when the infant cries
![Page 34: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/34.jpg)
Note in records if…
• Narrow, flat palate roof OR• High, arched palate
– affect the tongue’s placement– feeding and speech problems
*Associated with congenital anomolies
![Page 35: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/35.jpg)
Child ENT Exam
![Page 36: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/36.jpg)
Modifying Your Instruments
• Oto/ophthalmoscope– Decorative covers
http://quickmedical.com/pediapals/products
![Page 37: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/37.jpg)
• Postpone until the end– often resist otoscopic and oral exams
• Be prepared to use restraint if encouraging the child fails– Ask parent to restrain
the child
![Page 38: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/38.jpg)
Restraining a Child – Oral Exam
• Seated in the parent’s lap, back to the parent and legs between the adult’s legs
• Parent can reach around to restrain the child’s arms with one arm and control the child’s head with the other
• Can usually be accomplished without forcing– Force only makes them more angry…
![Page 39: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/39.jpg)
Restraining a Child - Otoscope
• Face the child sideways with one arm placed around parent’s waist
• Parent holds the child firmly against his/her trunk– One arm restrains the head– One arm restrains the body
• Doctor further stabilizes the child’s head while inserting the otoscope
![Page 40: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/40.jpg)
![Page 41: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/41.jpg)
Restraining a Child - Supine
If the child actively resists…• Place child supine on the exam table• Parent holds arms extended above the
head and assists in restraining the head• Doctor lies across the child’s trunk and
stabilizes the child’s head • Third person may need to hold the
child’s legs
![Page 42: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/42.jpg)
Remember
“Children of any age who are not too big to sit on a parent’s lap are better examined there than in a prone or supine position on the
examining table.”
![Page 43: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/43.jpg)
Child Ear Exam
Otoscopic exam• Pull auricle either down and back OR up
and back – gain best view of the tympanic membrane
As the child grows, the shape of the auditory canal changes to the S-shaped curve of the adult.
![Page 44: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/44.jpg)
• If the child is crying or has recently cried vigorously…– Dilation of blood vessels in the
tympanic membrane can cause redness “red reflex”
• Cannot assume that redness of the membrane alone is a middle ear infection
![Page 45: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/45.jpg)
Pneumatic Otoscope• needed to differentiate
Crying Red Moveable
Infection RedNo mobility *see common
conditions at the end of this ENT section
![Page 46: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/46.jpg)
Tympanometry
• Accurate way to identify middle ear effusion– Ear piece must be sealed in the canal
to provide accurate reading– Wax, ruptured membrane, tubes
![Page 47: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/47.jpg)
Toddler’s Hearing
• Observe response to a whispered voice and various noise makers– Rattle, bell, tissue paper– Outside of the child’s vision
• As they get older, ask child to perform tasks in a soft voice– May want to have a parent do it…– Avoid visual cues
• Use words that have meaning for them– Big Bird, Mickey Mouse, Barney
![Page 48: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/48.jpg)
Child’s Hearing
Weber, Rinne, and Schwabach tests• Used only when a child
understands directions and can cooperate with the examiner– Usually 3-4 years of age
• Refer for audiometric screenings
![Page 49: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/49.jpg)
Nose Exam
Inspect internal nose• Usually adequate to tilt the nose
tip upward– Largest otoscopic speculum may be
used• Visualization of larger area
![Page 50: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/50.jpg)
“Adenoidal” or “Allergic Salute”
• Children often wipe their noses with an upward sweep of the palm of the hand– If repeated often enough, causes a
crease
• Transverse crease at the juncture between the cartilage and the bone of the nose
![Page 51: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/51.jpg)
Sinuses – Child
• Maxilary sinuses should be palpated
• Few sinus problems occur since the sinuses are still developing– Wide variation however– Do not rule out sinusitis simply on the
basis of age
![Page 52: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/52.jpg)
Child Mouth Exam
Getting cooperation• Let the child hold and manipulate
the tongue blade and light– Reduce fear of the procedure
• Start by asking to see their teeth– Usually not threatening
![Page 53: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/53.jpg)
• Ask child to protrude the tongue and say “ ah”– Tongue blade is often
unnecessary
• Ask the child to pant “like a puppy”– Raises the palate
![Page 54: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/54.jpg)
If child refuses to open mouth…
• Insert a tongue blade through the lips to the back molars
• Gently but firmly insert the tongue blade between the back molars and press the blade to the tongue
• This should stimulate the gag reflex– Gives you a brief view of the mouth
and oropharynx
![Page 55: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/55.jpg)
Inspection
• Highly arched palate– Children who are chronic mouth
breathers
Why are they breathing through their mouth?
![Page 56: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/56.jpg)
• Flattened edges on the teeth– Bruxism
• Unconscious grinding of the teeth
Why are they grinding?
![Page 57: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/57.jpg)
• Baby bottle syndrome– Multiple brown areas (caries) on
upper and lower incisors– d/t bedtime bottle of juice/milk
![Page 58: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/58.jpg)
• Black or grey colored teeth– Pulp decay– Oral iron therapy
• Mottled or pitted teeth– Tetracycline treatment during tooth
development– Enamel dysplasia
![Page 59: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/59.jpg)
Tonsils• Should blend with the color of the
pharynx• Gradually enlarge to their peak size
between 2 - 6 years– should retain an unobstructed passage
• Graded to describe their size
![Page 60: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/60.jpg)
Grading Tonsils
1+ -visible2+ -halfway
between tonsillar pillars and the uvula
3+ -nearly touching the uvula
4+ -touching each other

Choanal Atresia
• Congenital nasal obstruction of the posterior nares– Junction between nasal
cavity and nasopharynx
• Newborns may experience respiratory distress– Obligatory nose breathers
*Will breathe when crying

– Only if tympanic membrane ruptures or through tympanostomy tubes; foul-smelling
• Hearing– Conductive loss as middle ear fills with pus
• Inspection– Tympanic membrane may be red, thickened,
bulging; full, limited, or no movement to +/- pressure
![Page 74: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/74.jpg)
Otitis Media with Effusion• Inflammation of the
middle ear resulting in the collection of liquid (effusion) – Serous, mucoid, or purulent
• Causes:– Allergies– Enlarged lymph tissue
(nasopharynx)– Obstructed or dysfunctional
eustachian tube
![Page 75: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/75.jpg)
Once the obstruction occurs…• middle ear absorbs the air,
creating a vacuum
• mucosa secretes a transudate into the middle ear
Average duration: 23 days
![Page 76: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/76.jpg)
• Initial Symptoms– Sticking or cracking sound on yawning or swallowing;
no signs of acute infection• Pain
– Uncommon; feeling of fullness• Discharge
– uncommon• Hearing
– Conductive loss as middle ear fills with fluid• Inspection
– Tympanic membrane is retracted, impaired mobility, yellowish; air fluid level and/or bubbles
![Page 77: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/77.jpg)
Sinusitis• Infection of or more paranasal sinuses
– May be a complication of a viral URTI, dental infection, allergies, or a structural defect of the nose
– Blockage of the sinus meatus prevents drainage
Symptoms:– Fever, headache, local tenderness, and pain
Signs:– May be swelling of the skin overlying the
involved sinus and copious nasal discharge
![Page 78: Ear, Nose, & Throat (c FW06) ppt child](https://reader033.fdocuments.us/reader033/viewer/2022061104/543da010afaf9fa40a8b4a3d/html5/thumbnails/78.jpg)
• Children may alternatively suffer from:– upper respiratory symptoms– nasal discharge– low-grade fever– daytime cough– malodorous breath– cervical adenopathy– intermittent painless morning eye
swelling– NO facial pain or headache

tonsils– Frequently caused by streptococci
Symptoms:– Sore throat, referred pain to the ears,
dysphagia, fever, fetid breath, and malaise
Signs:– Tonsils appear red and swollen;
