Mehl. and UW Rine-weber Flashcards
!!! (28) A 5-year-old boy is brought to the clinic by his parents due to hearing loss. Over the past year, the patient has had increased difficulty hearing normal conversations. He was born at 36 weeks gestation and was small for gestational age but otherwise has had no medical problems. He is at the 50th-75th percentile for height, weight, and head circumference. A tuning fork held over the middle of the forehead sounds louder in the left ear.Tuning fork sounds are better heard with air conduction bilaterally. Which of the following is the most likely etiology of this patient’s hearing loss?
Congenital infection
CMV

(28) Conductive hearing loss = where pathology?
External or middle ear disease (decr. hearing of room noise)
(28) Sensineural hearing loss = where pathology?
Inner ear disease (decr. hearing of room noise and tuning fork)
Mehl. Rinne test?
A vibrating tuning fork is placed against the mastoid bone (bone conduction; BC). Once the patient can no longer hear it, it is removed from the bone and placed in front of the ear canal (air conduction; AC).

Rinne test
Mehl. Weber test?
vibrating tuning fork is placed on the center of the forehead or top of the head, and the patient is asked if they hear the sound equally in both ears or if it’s louder in one ear.

Weber test
Mehl. Rinne test. For both normal hearing and sensorineural hearing loss AC vs BC?
AC > BC.
Mehl. Rinne test. For conductive hearing loss?
BC > AC (in affected are)
in unaffected = normal (AC>BC)
Mehl. Rinne test, if it is louder in one ear, this is called ?
“lateralization” to that ear.
Mehl. Normal hearing. Rinne, weber?
Rinne shows air > bone conduction; Weber does not lateralize.

.
(28) This patient’s Weber test localizes to the left (unaffected) ear, and he hears air conduction louder than bone conduction bilaterally. These findings are consistent with right-sided sensorineural hearing loss (SNHL). SNHL results from damage to the inner ear or auditory nerve. The most common cause of nonhereditary SNHL in children is congenital cytomegalovirus (CMV) infection.
