Abstract
The aim of this study was to determine the improvement in speech recognition provided by a cochlear implant (CI) in conjunction with a hearing aid (HA) in the opposite ear. The study was a retrospective cohort study in the context of a university teaching hospital CI programme. Seven CI patients who still use their HA in the opposite ear were tested. The scores with the CI alone and the CI in conjunction with an HA were evaluated by using three speech perception tests in quiet (Freiburger Numbers, Freiburger Monosyllables, and Innsbrucker Sentence Test). In the majority of tests and subjects, the CI alone performed better than the HA alone, and the bimodal (CI+HA) condition was superior to the CI alone. On the sentence test, the patients as a group improved from 47-96% (mean: 79%; CI alone) to 50-100% (mean: 88.1%; CI+HA, pv<0.05). With the more difficult monosyllable test, the scores improved from 15-52% (mean: 37.2%; CI alone) to 15-82% (mean: 48.7%; CI+ HA, p<0.05). On the numbers test, scores increased from 65-98% (mean: 83%; CI alone) to 75-98% (mean: 88.7%; CI+ HA, p<0.05). All patients in this study were implanted in the poorer ear. The results of the present study suggest the advantage of CI usage in conjunction with an HA in the opposite ear.

Modelling the risk of noise-induced hearing loss among military pilots.

Abstract
Noise is a significant risk factor in aviation, especially in military aviation. Even though our earlier studies have shown that the risk of noise-induced hearing loss (NIHL) among military pilots is small and the monitoring of their hearing is effective, we still need to develop methods of assessing the risk of NIHL more effectively at both the general and individual levels. In addition, many other risk factors are considered to contribute to the development of hearing impairment. The novel NoiseScan data management system enables assessment of the risk of developing hearing impairment on the basis of known risk factors. This study investigates the risk of hearing impairment among Finnish Air Force pilots using reasonably accurate noise exposure data and other risk factors for hearing impairment. This risk is also compared with that of industrial workers, whose risk followed the ISO 1999 prediction. Hearing among Finnish military pilots turned out to be better than predicted by the ISO 1999 model. The industrial workers had a larger number of risk factors than the pilots. Owing to the small number of risk factors, the hearing of pilots corresponds to approximately the 80th percentile, being 9-13 dB better than the 50th percentile obtained with the industrial population.

The Prevention of Recurrent Cholesteatoma in CWU Surgery: The Use of Titanium Sheeting.

Objective: Assessment of the outcomes of a technique of prevention of recurrent cholesteatoma in canal wall up (CWU) mastoidectomy, using titanium sheeting to repair the external auditory canal wall. Patients: Sixty four cholesteatoma cases were managed during a period from 2007 to 2015. The cases were unselected; the surgery was performed by the senior author. Cholesteatoma Patterns Were: Forty two attic, nine pars tensa, seven combined attic-pars tensa, three congenital, and three other. Primary surgery was undertaken in 33 cases. Interventions: All cases underwent CWU surgery that employed canal wall repair using fine titanium sheeting combined with overlying organic material to repair canal wall defects. Drum repairs employed cymba conchae cartilage-perichondrium composite grafts. Chain reconstruction used Spanner struts or Grace Alto PORPs or TORPS. Results: Two cases suffered mesotympanic residual disease, and three, mesotympanic recurrence one of which extended into the attic. Two other cases incurred atticomastoid residues. Transient myringitis occurred in three cases. Conclusion: The surgery was judged on its ability to avoid atticomastoid recurrence, and was regarded as highly successful. The titanium sheeting offers a relatively simple but effective technique. The mesotympanic complications are those also commonly found in both CWD and other CWU methods. As in other CWU procedures, the problems of the open cavity were avoided. Copyright (C) 2017 by Otology & Neurotology, Inc. Image copyright (C) 2010 Wolters Kluwer Health/Anatomical Chart Company
