A 2023 pilot study examined whether earwax chemical patterns could distinguish people with Ménière’s disease from those without it.
2
Three fatty acids were detected in both groups, but their concentrations were lower in samples from patients with Ménière’s disease.
3
Average concentrations of cis-9-hexadecenoic, cis-10-heptadecenoic, and cis-9-octadecenoic acids were approximately 78%, 85%, and 58% lower, respectively.
4
The classification model correctly categorized 3 additional samples, but its internal performance was modest and the small test set cannot establish diagnostic accuracy.
5
The mass spectrometry-based approach remains at an early laboratory stage and requires larger prospective studies before its diagnostic performance can be determined.
