When performing the otoscopic examination, how do you move the auricle for children?
|
pull the auricle either downward and back or upward and back to gain the 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.
|
|

|
|
What is MIDDLE EAR EFFUSION ?
Signs of it? Common causes? |
inflammation of the middle ear resulting in the collection of serous, mucoid, or purulent fluid (effusion)
bulging of the tympanic membrane, limited or absent mobility of the tympanic membrane, air fluid level behind the tympanic membrane, and otorrhea. Conductive hearing loss often results. Obstructed or dysfunctional eustachian tube, allergies, and enlarged lymphoid tissue in the nasopharynx. |
|
What is ACUTE OTITIS MEDIA ?
What are the signs? What can cause this? |
abrupt onset of symptoms and signs of middle ear inflammation and middle ear effusion
Signs of middle ear inflammation include distinct erythema of the tympanic membrane or distinct otalgia (ear pain) in the affected ear that interferes with normal activity and sleep bacterial infections |
|
What is CHOLESTEATOMA?
What can you see? What can cause a smell? Symptoms? Problem if left untreated? |
epithelial growth that migrates through a perforation in the tympanic membrane
White, shiny, greasy flecks of debris are visualized in the posterior-superior section of the middle ear through the tympanic membrane or through a perforation. A foul-smelling discharge may be found when a perforation is present. Symptoms include progressive hearing loss, fullness in the ear, tinnitus, and mild vertigo. If untreated, the cholesteatoma can lead to intracranial complications by eroding the temporal bone |
|
What is OTOSCLEROSIS ?
Symptoms? What kind of hearing loss? |
Otosclerosis is a hereditary condition that is more common in women. Irregular ossification occurs within the bony labyrinth or otic capsule, resulting in fixation of the stapes.
Symptoms include tinnitus and slowly progressive low- to medium-pitch conductive hearing loss, usually noticed between late teens and 30 years of age. Sensorineural hearing loss may also develop, causing a mixed hearing loss. |
|
What is MÉNIÈRE DISEASE?
Symptoms? What do patients complain about? |
Ménière disease affects the vestibular labyrinth, leading to profound sensorineural hearing loss.
Symptoms include abrupt and recurrent attacks of severe vertigo, tinnitus, and progressive hearing loss, initially of low tones. The patient may complain of fullness in the ears. The disorder may be unilateral at first and then may involve the other ear. |
|
What is LABYRINTHITIS ?
Symptoms? This can come from? |
Inflammation of the labyrinthine canal of the inner ear occurs as a complication of an acute upper respiratory viral or bacterial infection.
Symptoms of severe vertigo, which are associated with nystagmus and which are increased in severity with head movement, may last for several days. Labyrinthitis may be a complication of otitis media or meningitis. |
|
What causes SINUSITIS?
|
infection of one or more of the paranasal sinuses may be a complication of a viral upper respiratory infection, dental infection, allergies, or a structural defect of the nose.
Sinusitis may be caused by a blockage of the sinus meatus that prevents drainage of secretions from the sinus cavity, by malfunction of the cilia that help move mucus, or by an overproduction of mucus as a result of inflammation. |
|
What are the Predictors of Sinusitis?
|
The strongest predictor of sinusitis is a combination of four or more of the following signs and symptoms:
(1) maxillary toothache, (2) purulent nasal secretions, (3) dull or opaque sinus transillumination, (4) poor response to decongestants, and (5) colored nasal discharge |
|
What are signs of COCAINE ABUSE ?
|
chronic nasal symptoms as sniffling, nasal congestion, recurrent nosebleeds, and sinus problems
Signs of very recent insufflation include hyperemia and edema of the nasal mucosa and rhinorrhea. White powder may still be present on the nasal hairs and mustache. Signs of chronic cocaine insufflation include scabs on the nasal mucosa, decreased perception of taste and smell, and perforation of the nasal septum due to ischemic necrosis of the septal cartilage resulting from chronic irritation. |
|
What is TONSILLITIS ?
What are the Symptoms? What causes this? What else is enlarged? |
Inflammation or infection of the tonsils is commonly caused by streptococci.
Symptoms include sore throat, referred pain to the ears, dysphagia, fever, fetid breath, and malaise. The tonsils appear red and swollen, and tonsillar crypts are filled with purulent exudate. Tonsils studded with yellow follicles are associated with streptococcal infections. Anterior cervical lymph nodes are enlarged. |
|
What are Predictors of Beta Strep Infection?
|
Clinical signs most predictive of group A beta-hemolytic Streptococcus (GABHS) include tonsillar enlargement and exudates, tender and enlarged cervical nodes, and pharyngeal erythema. However, even when all these signs are present, they provide no assurance of diagnosis with only a 71% sensitivity and 77% specificity. A throat culture is still vitally important for an accurate diagnosis
|
|
What is PERITONSILLAR ABSCESS?
Symptoms? What is red and swollen? What is present? |
Infection of the tissue between the tonsil and tonsillar pillar occurs as a complication of tonsillitis.
Symptoms include dysphagia, drooling, severe sore throat with pain radiating to the ear, muffled voice, malaise, and fever. The tonsil, tonsillar pillar, and adjacent soft palate become red and swollen. The tonsil may appear pushed forward or backward, possibly displacing the uvula. Cervical lymphadenopathy is present. |
|
How do ORAL CANCER appear?
Where are they? What are the signs? What is usually present? |
ulcerative lesion that may be erythematous, white, or pigmented, appearing as piled up edges around a core that often appears on the lateral border or floor of the mouth.
Other locations are the hard and soft palate and the alveolar ridges. Signs include a sore in the mouth that will not heal, a white or red patch on the gums, tongue, tonsil, or buccal mucosa, bleeding, ulceration, and a lump or thickening in the cheek. Early lesions are usually painless, but advanced lesions become painful with erosion of tissue. Cervical adenopathy is usually present |
|
What is SLEEP APNEA ?
What problem can this cause? What can this result in? What is the typical patient profile for this? |
periodic cessation of breathing during sleep that is associated with either an obstruction to airflow or with failure of the central nervous system to stimulate the respiratory effort to breathe.
In obstructive sleep apnea, muscles in the nasopharynx, hypopharynx, and pharynx relax during sleep, resulting in loud snoring, restless sleep, and a pause in nasal and oral airflow with respiratory effort. This can result in progressive hypercapnia, hypoxemia, increased pulmonary arterial pressures, and possibly life-threatening cardiac arrhythmias. Patients are typically overweight, middle-aged men who complain of excessive daytime sleepiness and morning headaches. This can occur in preschool children when enlarged tonsils and adenoids obstruct the airway. |
|
What race has higher incidence of Cleft Lip and Palate?
|
The incidence of cleft lip and palate is higher in whites and Japanese, and lower in blacks.
|
|
What is RETROPHARYNGEAL ABSCESS ?
What can cause this? Who gets this condition a lot? |
abscess is a pediatric emergency because it occludes the airway
trauma to the posterior pharyngeal wall or a dental infection that leads to infection in the retropharyngeal lymph nodes. Group A Streptococcus and Staphylococcus are common causative organisms most common in children younger than 3 to 4 years because the retropharyngeal lymph nodes tend to atrophy by 5 or 6 years of age |
|
What is PRESBYCUSIS ?
Cause? What perception is loss? What other problem will occur? |
Presbycusis is a common auditory disorder in which there is bilateral sensorineural hearing loss associated with aging.
It is caused by degenerative changes in the inner ear or auditory nerve. There is a loss in the perception of auditory stimuli-initially of high-frequency sounds-and tinnitus. Speech may be poorly understood when spoken quickly or when background noise is present. |
|
What is XEROSTOMIA ?
Causes? What type of patients get this condition? |
Xerostomia is a dry mouth
caused by the ingestion of anticholinergic or antidepressant drugs that interfere with the production of saliva.
