Ventilation tube insertion (VTI) for OME
Ventilation tube insertion was performed under general anesthesia in
pediatric patients and under local anesthesia in adults. The procedure
included myringotomy on the anterior-inferior quadrant of the tympanic
membrane, followed by drainage of the middle ear fluid and interposition
of the ventilation tube through the ear drum. Different ventilation
tubes (Sheehy-Type Collar Buttons, Medtronic, USA, Inc) with diameters
of 1.02 and 1.27 mm were selected for pediatric and adult patients,
respectively. Irrigation with ofloxacin (3 mg/mL) (Tarivid; Daiichi
Sankyo, Japan) was performed following ventilation tube stabilization.
