Insights

Pediatric cochlear implant device failure occurs in 4.7% of cases, necessitating revision surgery. Fortunately, hearing outcomes remain stable after revision, ensuring no decline in auditory performance.

Area of Science:

  • Otolaryngology
  • Pediatric audiology
  • Biomedical engineering

Background:

  • Pediatric cochlear implantation risks often omit device failure and revision surgery rates.
  • Limited data exists on pediatric cochlear implant failure and post-revision hearing outcomes.
  • This study addresses the need for comprehensive data to guide family counseling.

Purpose of the Study:

  • To investigate the incidence of cochlear implant device failure in pediatric patients.
  • To analyze hearing outcomes following revision surgery in children.
  • To inform preoperative counseling for families considering pediatric cochlear implantation.

Main Methods:

  • Retrospective chart review of pediatric cochlear implantations.
  • Data collected from 2004 to 2014.
  • Analysis of device failure, infection, extrusion rates, and audiometric data.

Main Results:

  • A 4.7% device failure rate was observed in 579 pediatric cochlear implantations.
  • Device infection and electrode extrusion rates were both 0.3%.
  • Audiometric data from 10 patients showed similar pure-tone averages before failure and after revision.

Conclusions:

  • Cochlear implant device failure is the most frequent long-term complication in pediatric cases.
  • Revision surgery does not lead to a decline in auditory performance, as measured by pure-tone average.
  • Findings support the safety and efficacy of revision surgeries for pediatric cochlear implants.

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Reaction Rate02:53

Reaction Rate

The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...

When two or more physical quantities are linked by a single relationship, a change in one variable necessarily affects the others. This interdependence forms the basis of related rates analysis, which examines how different quantities change with respect to time. A classic physical example is an expanding balloon, where the size of the balloon changes continuously as air is added.For a hot air balloon, the inflated envelope is commonly idealized as a perfect sphere to simplify mathematical...

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Measuring Reaction Rates

Polarimetry finds application in chemical kinetics to measure the concentration and reaction kinetics of optically active substances during a chemical reaction. Optically active substances have the capability of rotating the plane of polarization of linearly polarized light passing through them—a feature called optical rotation. Optical activity is attributed to the molecular structure of substances. Normal monochromatic light is unpolarized and possesses oscillations of the electrical...
