Nonsurgical home treatment of middle ear effusion and associated hearing loss in children. Part II: Validation study.

In this prospective follow-up investigation, we examined the efficacy of a modified Politzer device in the home treatment of persistent middle ear effusion (MEE) and associated hearing loss in children who had previously participated in a similar clinical trial. Our study group was made up of 38 patients who had been either (1) untreated control participants in the previous study whose hearing in one or both ears had not returned to normal within 11 weeks of their initial audiologic pretest ("former control group"; n = 30), or (2) active-treatment participants in the previous study whose hearing sensitivity in at least one ear had not improved to within normal limits after treatment and who elected to undergo a continuation of treatment ("extended-treatment group"; n = 8). Treatment efficacy was determined by comparing differences in pre- and posttreatment air-conduction thresholds and otoscopic findings.

Nonsurgical home treatment of middle ear effusion and associated hearing loss in children. Part I: clinical trial.

We conducted a randomized, controlled clinical trial to investigate the efficacy of treatment of persistent middle ear effusion (MEE) and associated hearing loss with a modified Politzer device used in the home setting over a 7-week period. Efficacy was determined by comparing pre-and posttherapy air-conduction thresholds, tympanometric peak pressures, and otoscopic findings. The study group was made up of 94 children (174 ears), aged 4 to 11 years, who had at least a 2-month history of MEE and associated hearing loss.
