Clinical findings of otitis externa
Pain Tenderness Aural d/c Fever absent Hearing unaffected Tenderness with movement of the pinna Lining of the auditory canal is inflamed with mild to severe erythema and edema Scant to copious d/c from the auditory canal
Tx of otitis externa
Ofloxacin
Ciprofloxacin with hydrocortisone or dexamethasone
Polymyxin B-neosporin-hydrocortisone
Seasonal allergic rhinitis
Caused by airborne pollens, which have seasonal patterns
Trees in spring
Grasses in late spring to summer
Weeds in summer and fall
Perennial allergic rhinitis
Primarily caused by indoor allergens, such as house dust mites, animal dander, mold, and cockroaches
Episodic rhinitis
Occurs with intermittent exposure to allergens
Sx of allergic rhinitis
Thin rhinorrhea
Nasal congestion
Paroxysms of sneezing
Pruritis of the eyes, nose, ears, and palate
PE of allergic rhinitis
Pale pink or bluish gray, swollen, boggy nasal turbinates with clear, watery secretions
Frequent nasal itching and rubbing of the nose with the palm of the hand (allergic salute)
Allergic shiners- dark periorbital swollen areas
Swollen eyelids or conjunctival injection
Labs for allergic rhinitis
Allergy testing
Tx of allergic rhinitis
Allergen avoidance Intranasal corticosteroids 2nd generation antihistamines Decongestants Immunotherapy
What is the most common cause of mild to moderate hearing loss in children?
Conduction abnormality
What is more common in severe hearing loss?
Sensorineural hearing loss
Causes of sensorineual deafness
Congenital infections
Tumors and their treatments
Genetic deafness
Dx of hearing impairment
Auditory brainstem response Otoacoustic emissions Audiologic assessment for young, neurologically immature, or behaviorally difficult children Pneumatic otoscopy Tympanometry
Tx of sensorineural hearing loss
Speech-language therapy Hearing aids ASL Special ed Cochlear implants
Indication for cochlear implants
Children >12 mos with profound sensorineual hearing loss who have limited benefit from hearing aids, have failed to progress in auditory skill development, and have no radiologic or medical contraindications
S/sx of mastoiditis
Posterior auricular tenderness, swelling, and erythema
Pinna is displaced downward and outward
Dx of mastoiditis
Radiographs or CT of the mastoid reveals clouding of the air cells, demineralization, or bone destruction
