Summary
Postoperative infections after cochlear implantation occurred in 10% of cases, with Staphylococcus aureus being the most common pathogen. Biofilm presence was linked to a higher risk of device explantation.
Area of Science:
- Otorhinolaryngology
- Infectious Diseases
- Biomedical Engineering
Background:
- Postoperative wound infections are a concern following cochlear implantation.
- Understanding infection rates, bacteriology, and biofilm formation is crucial for patient outcomes.
Purpose of the Study:
- To determine the frequency and management of postoperative wound infections after cochlear implantation.
- To investigate the bacteriology and biofilm formation in these infections.
Main Methods:
- Retrospective file review of 653 adult cochlear implantations (1994-2015).
- Infections classified using a reporting consensus.
Main Results:
- Overall infection rate was 10% (2% major, 8% minor).
- Explantation due to infection occurred in 1% of cases.
- Staphylococcus aureus was the most frequent pathogen; biofilm was present in 73% of explantations.
Conclusions:
- While 10% of cochlear implantations resulted in infection, most were not severe.
- Staphylococcus aureus is the primary pathogen, and biofilm may increase explantation risk.

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

01:26Defense Mechanism Against Infection
9.8K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

01:26Factors Affecting the Risk of Infection
13.7K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
