n. pl. stapes or sta·pe·des (stā′pĭ-dēz′)
The innermost of the three small bones of the middle ear, shaped somewhat like a stirrup. Also called stirrup.

[New Latin stapēs, stapēd-, from Medieval Latin, stirrup, perhaps alteration (influenced by Latin stāre, to stand, and pēs, ped-, foot) of staffa, stapha, of Germanic origin; akin to Old English stæpe, stepe, step.]

sta·pe′di·al (stā-pē′dē-əl) adj.

These include electrically evoked auditory brainstem response (EABR), electrically evoked stapedial reflex threshold (ESRT), electrically compound action potentials (ECAP), middle latency responses (MLR), and cortical responses (CR).
Type IV: The stapedial footplate is movable, but the crurae are missing.
Stapedial involvement was significantly higher in the recurrent cases than in the non-recurrent cases (p=0.021) (Table 1).
Kulesza said stapedial reflex testing provides much more information about the types of dysfunction that may be present.
Incus is more vulnerable to traumatic injury, being the heaviest and weakly anchored ossicule, while malleus is stabilised by the tensor tympani tendon and stapes by the stapedial tendon (2, 6, 7).
The carotid artery anomalies associated with PHACE syndrome (including aplasia/hypoplasia, stenosis and redundancy) as well as persistent stapedial arteries encountered in the temporal bone are included within this category.
A large, pulsating vessel was found passing through the crura of the stapes, consistent with a persistent stapedial artery (PSA) (figure 2).
Absence of contralateral and ipsilateral stapedial reflexes.
Impedance audiometry showed a tympanogram type A bilaterally, with a stapedial reflex (SR) threshold of 95 dB (only in the case of 0.5 kHz, 1 kHz) in the right ear and 85 dB in the left ear (in the case of 0.5 kHz, 1 kHz, 2 kHz, 4 kHz).
Audiometric assessments consist of auditory brainstem response, pure tone audiometry, distortion product otoacoustic emission, tympanometry, and acoustic stapedial reflex.
Audiometric (pure-tone audiometry, speech audiometry, stapedial reflex, otoacoustic emissions, and brainstem auditory-evoked potentials) and neurootologic tests (clinical testing, electronystagmography, spontaneous nystagmus, gaze directional test, saccades, smooth pursuit, caloric test and head impulse and head shaking test, subjective visual vertical, and posturography) were taken along with magnetic resonance imaging in all the patients.
