Which of the following statements is not true about SNHL?
SNHL stands for standing nerve hearing loss
Ototoxic drugs are not which of the following?
Vitamin B12
(T/F) Diseases and disorders that can produce sensory hearing loss in the postnatal period include a diverse assortment of infections that affect the inner ear and also a number of medications used to treat the infections.
True
Connexin 26 Mutations
most common cause of congenital SNHL; AUTOSOMAL RECESSIVE
perinatal (during birth) period
contribute to hearing loss ranging from inadequate oxygen or blood supply to the auditory system to
exposure to medications that are potentially damaging to the cochlea
postnatal (after birth) period
include a diverse assortment of infections that affect the inner ear and also a number of medications used to treat the infections.
Nonsyndromic hearing loss
most common; the primary problem is a deficit in hearing that is not associated with other
abnormalities.
Dual sensory impairment
abnormality in two senses, such as the auditory and visual senses.
Usher’s Syndrome
SNHL and Retinitis Pigmentosa; Progressive hearing loss and blindness
CHARGE (involve dual sensory impairment but they are
not syndromes)
-Coloboma of the eye, central nervous system abnormalities
-Heart defects
-Atresia of the nasal choanae
-R[SLUR] of growth and development -Genital and/or urinary abnormalities -Ear abnormalities and deafness
Rubella
bacterial infectious disease that may
cause sensorineural hearing loss
Meningitis
viral or bacterial microorganisms can cause an infection and related inflammation of the meninges; can cause SNHL
Other disorders that can cause inner ear disorders
herpes virus, HIV
Autoimmune inner ear disease (AIED)
In patients with autoimmune inner ear disease, antibodies or immune cells damage inner ear structures; treatment: steroids
MENIERE’S DISEASE AND ENDOLYMPHATIC HYDROPS
-Fluctuating hearing loss
-Episodic vertigo
-Tinnitus (low-frequency roaring sound)
-A sensation of ear fullness or pressure
Medical Intervention for Meniere’s
- The main goal for management of Meniere’s disease is to minimize or eliminate vertigo and to improve hearing status.
- Treatment strategies include: Medication to reduce excessive accumulation of cochlear fluids
-Injection of drugs to reduce vestibular function
-Surgery that involves cutting the vestibular nerve on one side
Sudden Idiopathic SNHL
Hearing sensitivity recovers completely for over one-
half of patients, even without aggressive medical
treatment.
Noise-induced hearing loss is characterized by
a notch-type decrease in hearing thresholds within the
region of 3000 to 4000 Hz.
Te m p o r a r y t h r e s h o l d s h i f t ( T T S )
decrease in hearing thresholds occurring during and immediately
after noise exposure and persisting for a period of sixteen to forty-eight hours.
Presbycusis
-age-related hearing loss; sensorineural and greater for higher frequencies (a sloping configuration).
-Amplification is the only treatment for Presbycusis
Monaural
Binaural
- one ear
-both ears
APD is an auditory disorder
APD is an auditory disorder that is not the result of global deficits such as autism, mental r[SLUR]
attention deficits, or similar impairments.
Treatment APD
highly individualized
Refers to stimuli
Dichotic: different stimulus to each ear simultaneously
