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.
