Q

falling test

A

Test used to observe balance and equilibrium. The patient is observed balancing on one foot, then with one foot in front of the other, and then walking forward with eyes open. The same test is conducted with the patient’s eyes closed. Swaying and falling with the eyes closed can indicate an ear and equilibrium malfunction.

Q

labyrinthectomy

A

surgical removal of the labyrinth

17
Q

labyrinthotomy

A

to cut into the labyrinth

18
Q

myringectomy

A

surgical removal of the tympanic membrane

19
Q

myringoplasty

A

surgical repair of the tympanic membrane

20
Q

myringotomy

A

surgical puncture of the eardrum with removal of fluid and pus from the middle ear to eliminate a persistent ear infection and excessive pressure on the tympanic membrane. A pressure equalizing tube is placed in the tympanic membrane to allow for drainage of the middle ear cavity; this tube typically falls out on its own

21
Q

otoplasty

A

surgical repair of the external ear

22
Q

pressure equalizing tube

A

small tube surgically placed in a child’s eardrum to assist in drainage of trapped fluid and to equalize pressure between the middle ear cavity and the atmosphere

23
Q

salpingotomy

A

to cut into the auditory tube

24
Q

stapedectomy

A

removal of the stapes bone to treat otosclerosis (hardening of the bone). A prosthesis or artificial stapes may be implanted

25
Q

tympanectomy

A

surgical removal of the tympanic membrane

26
Q

tympanoplasty

A

surgical repair of the tympanic membrane

27
Q

tympanotomy

A
