ECochG Atlas · Cases
Clinical cases
Nine vignette-driven interactive cases, one per disease module. Each case presents a clinical scenario, ECochG findings, and a multiple-choice question with click-to-reveal rationales and a teaching point. Best worked alongside the parent module — the case sits at the end of the relevant chapter. See also /quiz, /practice, and /compare.
Case 5.1
A 42-year-old with episodic vertigo, low-frequency SNHL, and SP/AP 0.64 on the right. Which interpretation is best supported?
Read full case →Case 6.1
Sound-induced vertigo, autophony, and an SP/AP of 0.39. Which is the most likely diagnosis and the best next step?
Read full case →Case 7.1
Absent ABR with apparent waveforms on click ECochG. What is the most important next ECochG manoeuvre, and what is the most likely diagnosis?
Read full case →Case 8.1
48 h of unilateral hearing loss and tinnitus, audiogram down 45 dB at 4–8 kHz. What is the most appropriate next test according to the 2019 AAO-HNSF guideline?
Read full case →Case 9.1
Pressure-induced vertigo after a barotrauma exposure; the Gibson postural protocol shows SP/AP change with head down. Which is the most reasonable role for ECochG in this case?
Read full case →Case 10.1
Progressive unilateral hearing loss, normal-looking click ECochG, asymmetric tinnitus. The ECochG is reassuringly normal. What is the most appropriate next step?
Read full case →Case 11.1
A 38-year-old musician with a normal audiogram who can't follow speech in noise. Which is the most appropriate response and management plan?
Read full case →Case 12.1
Mid-insertion CM amplitude drops 35% over two electrode contacts. What is the most appropriate response?
Read full case →Case 13.1
Click ECochG shows a clear AP but the ABR has no identifiable wave V at 80 dB nHL. What is the most appropriate next step?
