Exploring the frontiers of vestibular migraine: A case series.

Introduction: Patients with episodic vestibular syndrome (EVS) whose symptoms resemble those of vestibular migraine (VM) but who do not meet the criteria for it are common.

Objective: To describe those patients suffering from EVS in whom defined etiologies have been ruled out in order to determine if their symptoms can be linked to VM.

Material And Methods: Prospective multicenter study.

Uncovered p1 and p2 waves preceding the N3 vestibular evoked neurogenic potential in profound sensorineural hearing loss.

Background: The N3 wave is a vestibular evoked neurogenic potential detected in some patients with profound sensorineural hearing loss (PSNHL) during brainstem auditory evoked potential (BAEP) analysis. In 1998, Kato et al. mentioned two electropositive waves preceding N3, which we named p1-p2, but no further description was given.

Subjective benign paroxysmal positional vertigo in patients with osteoporosis or migraine.

Introduction: Subjective benign paroxysmal positional vertigo is a form of benign paroxysmal positional vertigo in which during the diagnostic positional maneuvers patients only present vertigo symptoms with no nystagmus.

Objective: To study the characteristics of subjects with subjective benign paroxysmal positional vertigo.

Methods: Prospective multicenter case-control study.

Normative data for static balance testing in healthy individuals using open source computerized posturography.

Purpose: Computerized posturography is the gold standard for balance assessment. Because of the great cost and dimensions of commercial equipments, low-cost and portable devices have been developed and validated, such as RombergLab, a software in open source term which works connected with a low-cost force platform. The objective of this study was to obtain normative posturography data using this software.

Normal and vestibular patterns in dynamic posturography in patients with Meniere's disease.

Introduction: The Sensory Organization Test of dynamic posturography allows a reliable assessment of the ability of any given patient to maintain a correct stability when conditions in the visual surrounding and/or support surface are deliberately modified. The results of this test can be analyzed according to the norms of the manufacturer of the device or through the application of specific formulae such as those by Cevette.

Objectives: To evaluate if the Cevette formulae distinguish correctly between the normal and vestibular patterns, as well as observing the differences between these two groups of patients (normal and vestibular), obtained either through standardized calculation or by the Cevette formulae.

[Myringoplasty: auditory follow-up and study of prognostic factors].

Objective: To perform a five-year study of hearing evolution in patients undergoing myringoplasty to determine whether eardrum repair correlates with improved hearing. We also studied factors that might predispose to failure and their usefulness as prognostic factors.

Material And Method: In a serial case study, we reviewed all myringoplasties performed at our centre during 2000, 2001, and 2002.

[Stapedotomy outcomes in the treatment of otosclerosis: our experience].

Objective: The main objective of our study is to identify whether there is measurable audiometric deterioration in patients undergoing stapedotomy with a follow-up of more than eight years.

Material And Method: We conducted a retrospective clinical study in which we reviewed a total of 150 case histories of patients with stapedotomy at our department between 1993 and 1997, with a successful initial audiological assessment using tone audiometry in the first three months after surgery and later audiometrical follow-up.

Results: We obtained a significant mean post-operative hearing impairment of 1.

[Abnormal internal carotid artery in the middle ear and severe otorrhagia after myringotomy].

We present a clinical-surgical case of a 72-year-old woman referred from another Hospital due to presentation of otorrhagia following myringotomy. We later determined by means of imaging studies that it was a case of an aberrant internal carotid artery. All masses in the middle ear, especially pulsing masses, must be studied by imaging methods such as computerized tomography and, preferably, magnetic resonance angiography.
