“…Common cavity deformity is typically associated with profound congenital hearing loss, [19][20][21][22][23][24][25][26][27][28][29][30] which is suspected early in the patient's life by means of routine transient-evoked otoacoustic emissions and subsequent automatic auditory brainstem response. An abnormal finding prompts for further characterization of the hearing loss by means of threshold auditory brainstem response and distortion-product otoacoustic emissions.…”

IMPORTANCECommon cavity deformity is a rare congenital inner ear malformation associated with profound hearing loss and attributed to an early developmental arrest of the cochlear-vestibular structures. This narrative review highlights the need to identify reliable indicators of hearing rehabilitation outcome.OBSERVATIONS Despite its relatively simple definition, common cavity deformity varies widely in morphologic features, presence of cochlear nerve fibers and remnants of Corti organ, and outcome after cochlear or brainstem implant. CONCLUSIONS AND RELEVANCECochlear implant has been shown to be a valid option for common cavity deformity, but its outcome remains variable and poor. Identification of specific neuroradiologic, audiologic, and neurophysiologic prognostic features; tailoring of the surgical approach; and standardization of outcome measures are needed to optimize the management of common cavity deformity and hearing rehabilitation after implant.

“…In EECS measurements of CI candidates Neumann et al 7 found postoperative speech recognition to correlate with frequency differentation but not with other measured variables [sensations, threshold level, temporal difference limen (TDL), dynamic range]. Takanami et al 8 used EECS successfully in awake child patients with inner ear anomaly to demonstrate electroneural hearing before cochlear implantation.…”

Evaluation of temporal difference limen in preoperative non-invasive ear canal audiometry as a predictive factor for speech perception after cochlear implantation

The temporal difference limen (TDL) can be measured with noninvasive electrical ear canal stimulation. The objective of the study wa to determine the role of preoperative TDL measurements in predicting patients’ speech perception after cochlear implantation. We carried out a retrospective chart analysis of fifty-four cochlear implant (CI) patients with preoperative TDL and postoperative bisyllabic word recognition measurements in Helsinki University Central Hospital between March 1994 and March 2011. Our results show that there is no correlation between TDL and postoperative speech perception. However, patient’s advancing age correlates with longer TDL but not-directly with poorer speech perception. The results are in line with previous results concerning the lack of predictive value of preoperativ TDL measurements in CI patients.
