Laser-assisted tympanic membrane fenestration (LTMF) provides intermediate-duration middle ear ventilation, which benefits selected children with acute otitis media (AOM) and otitis media with effusion (OME). Objective: To evaluate clinical and technical factors that may affect duration of LTMF patency. Design: Prospective clinical cohort effectiveness trial. Setting: Four tertiary care children's hospitals. Patients: Volunteer sample of 251 children (430 ears) followed up at 1, 2, 3, 4, 8, and

Interventions: Laser-assisted tympanic membrane fenestration for prospectively defined AOM or OME. The surgeon determined spot size, wattage, and concurrent adenoidectomy based on clinical judgment. Main Outcome Measures: Cure of AOM/OME with effusion at 90 days and duration of LTMF patency relative to spot size (1.8-2.8 mm), fenestration location on tympanic membrane, power (7-22 W), concurrent ad-(REPRINTED) ARCH OTOLARYNGOL HEAD NECK SURG/ VOL 129, AUG 2003 WWW.ARCHOTO.COM 825 Corresponding author and reprints: Ellen S.
