RESUMEN
There is increasing interest in the effect, otitis media with effusions (OME) has on the balance in children. The aim of our investigation was to determine whether a universal effect on balance could be demonstrated in children with OME by using sway posturography. Assessment was made in 20 children with proven OME before and after the insertion of bilateral ventilation tubes. Sway posturography was performed on each occasion in each of the four recording conditions in the presence and absence of both reduced optic fixation and reduced proprioception. The pathlength traversed during the recording interval was measured and analysed by a split-unit anova. The results demonstrate an overall improvement in mean pathlength of 20% following treatment of the effusions (P < 0.001) (95% CI 14-25%). The effect of reduced optic fixation and of reduced proprioception were similar when increasing the mean pathlength by 22% (P < 0.001). These results demonstrate that OME has a universal effect on balance in all recording conditions.

Glomus tumours can present in several sites in the head and neck. A red mass in the middle ear, visible on otoscopy generally indicates a glomus tympanicum or glomus jugulare. We present photographic and radiologic evidence of such a lesion arising from the course of the intra-tympanic facial nerve, the Fallopian canal, and review the differential diagnoses.
