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.
Insights
Myringosclerosis, a condition affecting the eardrum, is more common in older patients and those with specific ventilation tube types and ear effusion. Frequent ventilation tube insertions increase risk and severity.
Area of Science:
- Otolaryngology
- Medical Research
- Epidemiology
Background:
- Myringosclerosis is a common sequela of ventilation tube insertion (VTI).
- Identifying risk factors for myringosclerosis is crucial for improving patient outcomes after VTI.
Purpose of the Study:
- To investigate potential risk factors associated with the development and severity of myringosclerosis following VTI.
Main Methods:
- Retrospective analysis of 582 patients undergoing VTI.
- Comparison of patient characteristics between groups with and without myringosclerosis.
- Statistical analysis of risk factors including age, effusion type, VT type, and VTI frequency.
Main Results:
- Myringosclerosis occurred in 28.9% of patients post-VTI.
- Older age, serous otitis media, type 2 ventilation tubes (VT), post-VTI perforation, and frequent VTI were associated with higher myringosclerosis rates.
- Severity of myringosclerosis correlated with effusion duration and VTI frequency.
Conclusions:
- Older age, serous effusion, type 2 VT, post-VTI perforation, and frequent VTI are potential risk factors for myringosclerosis.
- Effusion duration and VTI frequency may influence the severity of myringosclerosis.
