Summary
This study shows that a percutaneous mastoid vent offers effective medium-term middle ear ventilation for patients with persistent ear problems. The mastoid vent demonstrated good patency and functional results in most cases.
Area of Science:
- Otolaryngology
- Biomedical Engineering
Background:
- A novel percutaneous mastoid vent was designed for permanent middle ear ventilation.
- The device features an osseointegrating titanium outer tube and an inner Teflon tube.
Purpose of the Study:
- To evaluate the outcomes of patients who received the mastoid vent since 1995.
- Assess the efficacy and safety of the percutaneous mastoid vent in clinical practice.
Main Methods:
- Retrospective study of 14 patients with ventilation problems unresponsive to conventional treatment.
- Follow-up assessed vent extrusion, skin reaction, patency, and functional results over 9-36 months.
Main Results:
- Only one vent extrusion occurred, with no dermatitis observed.
- All vents remained patent, achieving successful ventilation in 9 out of 14 ears.
- Improved hearing was noted in 6 of 8 ears with intact ossicles; adhesions were seen in 4 ears.
Conclusions:
- The percutaneous mastoid vent provides effective medium-term ventilation for the middle ear.
- The device shows promise for managing chronic ear ventilation issues.
