Background@#This study examined possible
risk factors for
myringosclerosis formation after
ventilation tube insertion (VTI). @*
Methods@#A
retrospective study was performed in a single
tertiary referral center. A total of 582
patients who underwent VTI were enrolled in this study.
Patients were divided into two groups based on the presence or absence of
myringosclerosis MS+ and MS−. Characteristics of
patients were collected through medical chart
review; these included age,
gender,
nature and duration of effusion, type of
ventilation tube (VT), duration and frequency of VTI,
incidence of post-VTI
infection,
incidence of intraoperative
bleeding, and presence of postoperative perforation.
Incidences of
risk factors for
myringosclerosis and the severity of
myringosclerosis in
association with possible
risk factors were analyzed. @*Results@#
Myringosclerosis developed in 168 of 582
patients (28.9%) after VTI.
Patients in the MS+ group had an older mean age than those in the MS− group. The rates of
myringosclerosis were higher in
patients with older age,
serous otitis media, type 2 VT, post-VTI perforation, and frequent VTI. However, there were no differences in occurrence of
myringosclerosis based on
gender, duration of effusion, duration of VT placement,
incidence of post-VTI
infection, or
incidence of intraoperative
bleeding. The severity of
myringosclerosis was associated with the duration of effusion and frequency of VTI. @*Conclusion@#Older age, serous effusion, type 2 VT, presence of post-VTI perforation, and frequent VTI may be
risk factors for
myringosclerosis after VTI; the severity of
myringosclerosis may vary based on the duration of effusion and frequency of VTI.
