Objective

2

To explore the correlation between SARS-CoV-2 infection and local flap infection in cochlear implantation surgery

so as to understand the impact of novel coronavirus infection on cochlear implantation surgery.

Methods

2

A retrospective analysis of 163 patients (divided into children and adults) who underwent cochlear implant surgery in our hospital from May 2020 to March 2023. Compare the differences between the study group (patients who have been infected with SARS-CoV-2) and the control group (uninfected patients) with local flap infection after cochlear implantation. The groups: (1) For Children's group of 1-18 years old

there were 44 in the study group and 64 in the control group. (2) Adult group: 18-67 years old

including 31 in the research group and 24 in the control group.

Results

2

There were 10 people with flap infection in the study group

with a incidence of 13.33% (10/75); while there were only 2 people in the control group

with a incidence of 2.27% (2/88). There is a significant difference between the two groups (

P

=0.017

<

0.05).After stratification by age

6 people with skin flap infection occurred in the children's research group

with a incidence of 13.64% (6/44); only 1 person with flap infection in the control group had 1.56% (1/64); therefore

there was a significant difference between the study group and the control group in children (

P

=0.035

<

0.05). In adults

4 people in the study group had skin flap infection and 1 person in the control group; there was no significant difference between the two groups (

P

=0.519

>

0.05).The degree of skin flap infection and the time of infection were analyzed. 1. In the study group

4 children were generally infected in the early stage

with an infection rate of 9.09% (4/44); 2 people with long-term severe infection

with an infection rate of 4.55% (2/44). Only one person in the child control group had an early general infection

with an infection rate of 1.56% (1/64); there was no early and long-term serious infection. 2. The adult research group generally infected 3 people in the early stage

with an incidence rate of 9.67% (3/31); 1 person with a long-term s

evere infection

with an incidence rate of 3.23% (1/31). There was only one case of early general infection in the adult control group

with a incidence rate of 4.17% (1/24); there was no early and long-term severe infection. There was no significant difference between the research group and the control group

and between different age groups in the time of infection and the degree of flap infection (

P

>

0.05).

Conclusion

2

SARS-CoV-2 infection increases the risk of local flap infection after cochlear implantation surgery; and the risk is relatively higher in children.
