Balance workshop: synchronized head and force plate measurements. The potential for diagnostic yields

Abstract

s / International Journal of Surgery 12 (2014) S13eS117 S43 of endoscopy-related oral mucosal injuries was 31.6%(24/76). Of these, 21 were recorded from the wet gauze subgroup, and 3 were from dental dam. The comparative mucosal injuries rate for wet gauze and dental dam was 37.5%(21/56) and 15%(3/20) respectively. No teeth trauma recorded. Conclusions: Alveolar ridge mucosal and gingival injuries remain a significant complication during rigid endoscopies. The routinely used wet gauzes appear inadequate in providing optimal protection. With the newly devised appliance, the dental dam may provide an alternative for oral protection during rigid endoscopies, although further studies are required. 1247: BALANCE WORKSHOP: SYNCHRONIZED HEAD AND FORCE PLATE MEASUREMENTS. THE POTENTIAL FOR DIAGNOSTIC YIELDS Cian O. Hughes, David D. Pothier, Paul Ranalli, John A. Rutka. Toronto General Hospital, Toronto, ON, Canada. Introduction: Currently only force-plate measurements are used in posturography. Given that the vestibular end-organs are situated within the temporal bone, recording movement of the head can provide additional information compared to body sway alone. We describe the synchronously recording of head position during posturography and investigate its potential additional value. Methods: A device was designed to capture information from headmountedaccelerometersandgyroscopes, allowingmovements andposition to be accuratelymeasured in three dimensions. Ten normal participants, ten patients with bilateral vestibular loss(BVL) and ten patients who were instructed tomalingerwere testedusing themodified clinical test of sensory interaction on balance(mCTSIB). Results: Our device accurately synchronized with the force-plate and allowed sway data to be calculated for the head. Normal controls showed a strong correlation between head and foot measurements: path length mean r-score1⁄40.57(p<0.001). This correlation became negative in BVL patients (mean r-score1⁄4-0.48(p<0.001)). Conclusions: This study suggests that head data are related to footplate data, but in pathologic conditions also provide different information from which diagnoses can be made. Given the small size of the device, it has the potential to be used over long periods. This allows for the telemetry of longitudinal data on sway. 1255: A PROSPECTIVE AUDIT OF CHRONIC RHINOSINUSITIS (CRS) MANAGEMENT AT A TEACHING HOSPITAL: BEFORE AND AFTER THE 2012 EUROPEAN POSITION PAPER GUIDELINES ON CHRONIC RHINOSINUSITIS (EPOS) Lulu Ritchie, Anna Slovick, Shilpy Ojha, Romana Kuchai.
