Methods: This pilot study included five patients with unilateral MD eligible from a cohort of twenty patients who underwent middle fossa vestibular neurectomy. All participants completed preoperative and 2-year postoperative clinical and audiological tests, including TT-ECochG; EH degree was analyzed in delayed gadolinium-enhanced magnetic resonance images (MRI). Changes in TT-ECochG parameters were analyzed in relation to MRI findings. Results: All patients achieved complete control of vertigo and improvement in the AAO-HNS functional level. Hearing deterioration of \u226510 dB was observed in two patients (40%). Cochlear EH remained unchanged in all patients, whereas vestibular EH reduction was visualized in two patients (40%) after surgery. Decreased SP\/AP amplitude and\/or area ratios were observed in two patients (40%), whereas increased values were found in two others (40%). No postoperative TT-ECochG response was obtained in one patient because of profound postoperative hearing loss. Overall, changes in TT-ECochG parameters did not parallel MRI findings. Conclusions: This pilot study demonstrates that postoperative TT-ECochG changes after vestibular neurectomy are heterogeneous and do not consistently parallel MRI changes in endolymphatic hydrops.<\/jats:p>","DOI":"10.3390\/jcm15187164","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T10:32:01Z","timestamp":1789468321000},"page":"7164","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Do Changes in Transtympanic Electrocochleography (TT-ECochG) Reflect the Dynamics of Endolymphatic Hydrops on MRI?
