- FIG 1.
Measurement of the midpoint vestibular aqueduct size in the Pöschl plane. The length of the VA is determined, and the midpoint level is located. A measurement line perpendicular to the VA length is used to measure the midpoint VA size.
- FIG 2.
Linear mixed-effects model with the effect estimates of VA size on the PTA (slope of line; 95% confidence interval, shaded gray). For every millimeter increase in the midpoint VA size, there is a 10.5 dB increase in the PTA (95% CI, 3.1–17.9 dB; P = .006).
- FIG 3.
Linear mixed-effects model with the effect estimates of the VA size on the SRT (slope of line; 95% confidence interval, shaded gray). For every millimeter increase in midpoint VA size, there is an increase of 14.0 dB in the SRT (95% CI, 5.2–22.7 dB; P = .002).
- FIG 4.
Linear mixed-effects model with the effect estimates of VA size on the WRS (slope of line; 95% confidence interval, shaded gray). For every millimeter increase in midpoint VA size, there is a 10.5% decrease in the WRS (95% CI, −21%–0%; P = .05).
