The OBCD is an effective way of rehabilitation for SSD. The BAHA improves the speech perception in noise but provided no significant improvement in sound localization as revealed in the postoperative test. With 3 questionnaires we noticed an improvement in the quality of life with the OBCD.

Laryngeal IONM can predict a favorable outcome of laryngeal mobility in cases in which the response exceeds 280 μV. Under this value, the risk of palsy is about 50% suggesting a staged surgery.

Endolymphatic pressure measurement is of interest both to researchers in the physiology and pathophysiology of hearing and ENT physicians dealing with Menière's disease or similar conditions. It is generally agreed that endolymphatic hydrops is associated with Menière's disease and is accompanied by increased hydrostatic pressure. Endolymphatic pressure, however, cannot be measured precisely without endangering hearing, making the association between hydrops and increased endolymphatic pressure difficult to demonstrate. Several integrated in vivo models have been developed since the 1960s, but only a few allow measurement of endolymphatic hydrostatic pressure. Models associating measurement of hydrostatic pressure and endolymphatic potential and assessment of cochlear function are of value to elucidate the pathophysiology of endolymphatic hydrops. The present article presents the main types of models and discusses their respective interest.
