    Abstract:
    OBJECTIVE: To describe the patient, disease and clinical characteristics that optimize the effectiveness of laser tympanic membrane fenestration (LTMF) to treat chronic otitis media with effusion (OME). SETTING: Four pediatric otolaryngology tertiary referral centers. IRB approved; participation by informed consent. METHODS: An observational clinical effectiveness trial was conducted in 164 ears (94 children), who had chronic OME. All patients were candidates for insertion of pressure equalization tubes (PETs) but agreed to undergo LTMF instead. Clinical and audiologic follow-up are reported at 90 days after LTMF. OUTCOME MEASURES: Clinical effectiveness was defined as an effusion free middle ear at otoscopy with A or C1 tympanogram and normal hearing. RESULTS: At 90 days, 66% of the 95 evaluable ears were effusion free, all with normal hearing. Children younger than 4 years (P<0.04), who had shorter durations of effusion (P<0.009), and who experienced longer duration of fenestration patency (FP) (P<0.009) correlated to improved outcomes. CONCLUSIONS: The use of LTMF to create 2--3 weeks of middle ear ventilation in patients with chronic OME (middle ear effusion (MEE) for 3 months or greater) is effective in 66% of 95 (58%) of ears evaluable at 90 days follow-up. This study provides basic information needed to optimize the use of LTMF today and enhance research efforts in the future.
