Characterization of newborn hearing screening failures in multigestational births.

Objective: To define the rate and characterize the type of newborn hearing screening failures in multigestational births.

Methods: Retrospective chart review of all multigestational births that occurred in a 10-year period (2002-2012) in which at least one newborn failed newborn hearing screening at two tertiary care hospitals in the Northwell Health System.

Results: Out of 125,405 total births, we identified 2961 multigestational births, of which 59 (2.

The experience of bilateral cochlear implantation in a child with LEOPARD syndrome.

We present a 3-year old boy with Leopard syndrome. His clinical manifestations included a congenital bilateral sensorineural hearing loss. He underwent cochlear implantation on the right side at age 1 year and on the left side at age 1.

Electrical compound action potentials recorded with automated neural response telemetry: threshold changes as a function of time and electrode position.

Objective: Since the introduction of neural response telemetry (NRT) for the Nucleus 24 cochlear implant (CI24), researchers and clinicians have investigated the feasibility of using the electrically evoked compound action potential (ECAP) threshold to objectively predict psychophysical measurements that are used in the programming of the speech processor. The ability to substitute objective for behavioral measurements, particularly measurements made at the time of surgery, would greatly facilitate programming the MAP for young children and other individuals who are not able to provide reliable behavioral data required for MAP programming. There have been a number of studies that have examined characteristics of the ECAP measured at the time of surgery and postoperatively; however, all the available published data are based on the CI24.
