Efficacy of Expansion Pharyngoplasty without Drug-induced Sleep Endoscopy Screening in Obstructive Sleep Apnea.

 Expansion sphincter pharyngoplasty has been shown to be a good alternative to continuous pressure devices in patients with moderate to severe obstructive sleep apnea. On the other hand, drug-induced sleep endoscopy provides information on the pattern of collapse in obstructive sleep apnea, although it is unclear whether this information improves the surgical outcomes.  To evaluate the success rate obtained when performing expansion sphincter pharyngoplasty on a group of patients diagnosed with moderate to severe obstructive sleep apnea who were not previously selected by drug-induced sleep endoscopy.

Functional positional eye and eyelid movements.

Background: Positional manoeuvres are an important part of the neurological examination, particularly in patients with vertigo where the presence and characteristics of provoked nystagmus can help differentiate central from peripheral neurological disorders.

Methods: Case series of functional positional eye and eyelid movements.

Results: We report four patients with functional eye and eyelid movements provoked during positional manoeuvres.

Practice Guidelines for the Diagnosis and Management of Benign Paroxysmal Positional Vertigo Otoneurology Committee of Spanish Otorhinolaryngology and Head and Neck Surgery Consensus Document.

Benign Paroxysmal Positional Vertigo is the most frequent episodic vestibular disorder. The purpose of this guide, requested by the committee on otoneurology of the Spanish Society of Otolaryngology and Head and Neck Surgery, is to supply a consensus document providing practical guidance for the management of BPPV. It is based on the Barany Society criteria for the diagnosis of BPPV.

Spectrum analysis in postural strategy on static tests in a healthy population.

Introduction And Objectives: The power spectral density can be used to find a hidden behaviour in a physical system. We studied postural behaviour in a healthy population, by means of power spectral density, and compared it with a situation of complete immobility.

Methods: A group of healthy volunteers carried out the modified Clinical Test for Sensory Interaction in Balance.

[Peripheral vertigo classification of the Otoneurology Committee of the Spanish Otorhinolaryngology Society: diagnostic agreement and update (version 2-2011)].

Introduction: In 2008, the Otoneurology committee of the SEORL-PCF published a classification of peripheral vertigo, based on clinical criteria. The objective of this study was to validate this classification through analysing the diagnostic agreement among several medical assessors.

Methods: Seven medical assessors, all with clinical experience, from 6 different hospitals, participated in the study.

Ocular counterrolling: an indicator of bilateral vestibulopathy.

The ocular counterrolling can be static or dynamic. The purpose of this work is to connect the clinical absence of dynamic ocular counterrolling with bilateral caloric paresis. A prospective study on 216 patients in whom the absence of dynamic ocular counterrolling was tested and standard caloric test was performed.

[Production of a virtual system to simulate nystagmus and ocular movements].

Objective: To describe a realistic and interactive system to simulate nystagmus and other ocular movements for teaching and professional speaking.

Material And Method: We obtained the base images by means of digital video, then edited and integrated them into a commercial animation computer program.

Results: The "nistagmoteca virtual", available free at the web address indicated.
