Ventilation tube surgery and middle ear irrigation.

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Infectious Disease

Background:

• Tympanostomy tube insertion is a frequent surgical procedure in the US.
• Postoperative otorrhea rates range from 10-20%, considered high.
• Standard surgical practice includes irrigation of drained spaces, but not typically the middle ear.

Purpose of the Study:

• To evaluate the efficacy of middle ear irrigation in reducing postoperative otorrhea after tympanostomy tube insertion.
• To assess the ability of irrigation to clear thick middle ear effusions.

Main Methods:

• Prospective, controlled, double-blind study.
• 220 consecutive cases of tympanostomy tube insertion.
• Utilized a soft plastic, angled irrigation catheter with radial ports.

Main Results:

• Middle ear irrigation reduced postoperative infections from 16% to 4% within six months.
• Irrigation effectively removed thick middle ear effusions, including those in difficult-to-access areas.
• Identified effusions missed by initial suction.

Conclusions:

• Middle ear irrigation is an effective method to decrease postoperative otorrhea after tympanostomy tube placement.
• Irrigation aids in the clearance of tenacious middle ear fluid, improving outcomes.
• A specialized irrigation catheter facilitates this procedure.
