Abstract
Laser-assisted tympanostomy (LAT) was performed in 70 ears to ventilate the middle ear space without using a pressure-equalizing tube. Using a CO2 laser attached to an operating microscope with a Microslad (microscope laser adaptor device), tympanostomies of 1.0 to 3.0 mm (average, 1.6 mm) in diameter were created and remained patent for an average of 3.14 weeks. Patency time was directly related to the size of the opening. Nearly all (97.9%) of the tympanostomies healed with no noticeable scarring and no persistent perforations. Seventy-eight percent of patients at the Florida Ear & Sinus Center (FESC, Sarasota, Fla.) and 84% of patients at the Head & Neck Surgery Group (New York) showed no evidence of recurrent effusion after a minimum follow-up of 3 months. LAT appears to be a safe, cost-effective procedure which can easily be performed in an office setting when bloodless opening in the tympanic membrane is needed for either treatment or diagnosis using endoscopes.
