RESUMEN
In this prospective study, we have proposed a new method to straighten the caudal septum using a modified spreader graft interlocked on the convex side. A single-interlocked graft inserted by 2 through-and-through serial sections of the quadrangular cartilage (applied over the misshapen convex side previously scored on the concave side) facilitated adjustment of the distal septum intraoperatively. The strip of cartilage of the desired height and width acted as a spring graft and may be placed at the desired height of the caudal septal area to exactly counteract the eventual tendency of the most deviated area to warp over time. All 15 patients treated had improvement of their nasal airway and in their postoperative appearance of the external and internal nose. Our technique is easy to perform and shows long-term reliability in correcting caudal septal deviation, demanding a wider application to confirm its effectiveness on a larger series of patients.

Sound-evoked activation of the vestibular system has been suggested for a long time, and myogenic potentials have been recorded at the level of different muscular groups while a high intensity sound was applied. The aim of this study was to analyse sound-evoked postural responses in normal subjects and to correlate them with the activation of the vestibular system. Body sway was measured by posturography and elaborated through spectral frequency analysis in 40 healthy volunteers in the basal condition and after applying a sound stimulus monoaurally. Spectral frequency analysis results showed a significant increase, in presence of stimulus, of body sway at low and middle frequencies only on the lateral plane and in the closed-eyes condition. As it seems that these frequency ranges are mainly under vestibular control, our results suggest that sound activates specifically the vestibular system, and posturography during sound stimulation represents an alternative approach to assess vestibular function.
