Methods:The English language literature was reviewed for studies including hearing preserva-tion and speech understanding for electrodes of different lengths. Results:One prospective trial was found, and there were no studies that randomized patients into different length electrodes with an intent to preserve hearing. Eight studies total included multiple length electrodes and contained data regarding hearing preservation. Conclusions: Although there is some evidence that indicates that shorter electrodes may improve both short and long-term hearing preservation rates in cochlear implant patients, no study has directly compared implant length on hearing preservation in a similar patient pop-ulation. A randomized trial of short and standard length electrodes for hearing preservation is warranted. In the interim, utilization of current electrodes measuring 20e25 mm could seem to be a prudent approach when seeking to preserve residual hearing without unduly compro-mising cochlear coverage.展开更多

Methods: Prospective, blinded study of inpatients requiring laryngoscopy. A live exam was per-formed, then a smartphone was attached to the endoscope using a novel coupling device and the same examination was recorded. The live and recorded exams were evaluated by two lar-yngologists, each blinded to the findings of the other. Results: Eighteen subjects were evaluated. Evaluation of airway patency was identical (Kappa = 1.0 [1, 1]). Evaluation of vocal cord motion was identical for 14 subjects: 9 normal, 3 paretic, 2 paralytic (Kappa = 0.69 [0.38, 1]). Conclusion: There is high correlation between laryngeal diagnoses using live flexible fiberoptic laryngoscopy and recordings using a coupling device to transfer the recordings on to smart-phones. Critical findings such as airway patency and vocal fold motion showed the highest cor-relation.展开更多
