Posterior Lingual Abscess; Report of Two Cases.

The lingual abscess is rare due to several protective mechanisms against infection in this location. Concretely, the abscess in the base of the tongue (posterior lingual abscess) is even more exceptional. Its prompt detection is crucial to avoid potentially fatal airway complications.

[Early start eosinophilic granuloma of the temporal bone].

Langerhans cell histiocytosis is a disease of unknown aetiology which may be isolated or affect multiple organs and which frequently affects the head and neck, with cranial compromise being one of the most common manifestations in children over five years. We present the case of a three year old girl with no otologic history who came to our hospital with a clinic of subperiostic abscess, subsequently diagnosed as eosinophilic granuloma. We describe the treatment and clinical evolution of the case.

[Contribution of the vestibular evoked myogenic potentials to the study of the vestibular neuritis].

Introduction: Until recently, the only tests available to provide information about vestibular function were caloric and kinetic tests, which only give us information about the external semicircular canal and the superior vestibular nerve. In recent years the development of vestibular evoked myogenic potentials has allowed us to assess the saccule and the inferior vestibular nerve. Our aim is, by studying the caloric test results as well as the vestibular evoked myogenic potentials in patients with Vestibular Neuritis, to determine whether they have involvement of the superior, inferior or both vestibular nerves.
