20.500.12556/DiRROS-29395 The impact of follow-up on etiological classification of pediatric vertigo Background: Vertigo and dizziness in children represent diagnostically challenging conditions with heterogeneous etiologies. At initial presentation, a substantial proportion of pediatric patients remain without a definitive etiological diagnosis. Evidence on the impact of longitudinal follow-up on etiological classification in pediatric vertigo is limited. Methods: This observational cohort study uses prospectively collected clinical data. Children aged 1-17 years who presented to a tertiary ENT clinic with vertigo and/or dizziness between 2015 and 2020 were systematically enrolled and followed. The present study represents a retrospective revision of a previously published cohort of 257 children. In 2025, extended follow-up data were reviewed to reassess etiological classification using the same diagnostic categories as in the original analysis. Descriptive statistics were applied to compare etiological distributions at initial evaluation and after follow-up revision. Results: After data revision, the proportion of children with unclassified etiology decreased from 44% to 10%. Central etiologies accounted for 35% of cases, peripheral vestibular disorders for 18%, hemodynamic causes for 16%, psychogenic etiologies for 10%, and other specific causes for 7%. Follow-up duration ranged from 0 to 132 months (mean 17.6 months; median 4.5 months). Diagnostic investigations were frequently performed; however, the etiological yield of certain tests, particularly cranial computed tomography, was low. Conclusions: Extended follow-up significantly improves etiological classification in children with vertigo and dizziness, demonstrating that diagnostic uncertainty at initial presentation often reflects evolving clinical phenotypes rather than the absence of an underlying disorder. A longitudinal, clinically guided, and multidisciplinary approach is essential to enhance diagnostic accuracy and optimize the use of diagnostic investigations in pediatric vertigo. dizziness etiology follow-up migraine pediatric vertigo vestibular disorders omotica etiologija sledenje migrena pediatrična vrtoglavice vrtoglavica pri otrocih true false true Angleški jezik Slovenski jezik Neznano 2026-05-15 09:49:46 2026-05-15 09:49:46 2026-05-16 03:49:11 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Opis vira z dne 12. 5. 2026; str. 1-13 no. 13 [Article no.] 376 Vol. 13 Mar. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.21 2227-9067 10.3390/children13030376 277870339 RAZ_Bozanic_Urbancic_Nina_2026.pdf RAZ_Bozanic_Urbancic_Nina_2026.pdf 1 FBFF556B6E778FAFC0085967330B67DF f24f0d913bffb27e329e49bb4252847f10437cde7d2d5d97e6f8db963a1e5f12 ba784750-5032-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44052 https://www.mdpi.com/2227-9067/13/3/376 1 a5990dfb-5032-11f1-8a5a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=44051 Univerzitetni klinični center Ljubljana 0 0 0
