Personal protective equipment for ENT activity during COVID-19 pandemic.

Background: In the COVID-19 era physicians have to face with need to perform office procedures maintaining the maximum safety for both the patient and the Doctor himself. The purpose of this paper was to suggest some equipment useful to perform outpatient visits in an ENT setting.

Methods: A simple modification of the standard headlight used during an ENT visit provides the operator a better face protection without any impairment in vision and comfort.

Nasal valve surgery.

The nasal valve region plays a key role in nasal breathing. In the international literature, a variety of techniques have been described to rectify nasal valve compromise, but based on the present evidence it is impossible to counsel a patient as to which technique is most effective. The aim of this study was to evaluate the results of surgery of the nasal valve through a hemitransfixion incision objectively with nasal endoscopy and rhinomanometry.

[Postural stabilization after otolithic repositioning for posterior semicircular canal canalization].

Today the canal/cupulolithiasic pathogenesis of benign paroxysmal positional vertigo (BPPV) appears well defined; what is less clear is the origin of the postural "instability" often associated with rotatory vertigo. This form is less marked but still resists all know treatments. The purpose of the present study was to determine the actual postural arrangement of subjects suffering from canalolithiasis (CL) of the posterior semicircular canal (PSC) both before and after the positioning maneuver.

[Alterations in postural control: the use of spectral analysis in stability measurement].

Unlabelled: Static posturography studies the frequency at which the center of gravity in the human body oscillates. There is no universal agreement as to the importance of this index or whether it is specific in identifying alterations in the postural control systems (vestibular, proprioceptive and visual). Nevertheless, some hypotheses appear generally accepted: a) visual information dominates; b) proprioception affects anterior-posterior oscillation; c) relatively low frequency body oscillation is affected by vestibular input while higher frequency oscillations are controlled by proprioceptive information.

[Changes in posture in whiplash evaluated by static posturography].

Analyzing vestibular-spinal reflex by recording changes in the pressure center over time, static posturography provides precise, repeatable information regarding a person's posture and subsequent postural strategy. Moreover, using the detected postural pattern, this can presage likely genesis of problems in equilibrium. The purpose of the present work was to evaluate posturographic findings in subjects with chronic or persistent whiplash (WL)-induced disequilibrium in order to determine any clear postural pattern able to indicate the likely genesis of the disorder.
