Abstract
Objective: In children with otitis media with effusion (OME), to investigat e the incidence of, and any association, between retractions of the pars te nsa and pars flaccida; to assess the effect of pars tensa and pars flaccida retractions on the hearing: to investigate risk factors for retractions; a nd to document the natural history of such retractions over a 12-week "watc hful waiting" period. Study Design: Prospective. observational study. Setting: Sixteen departments of otolaryngology in hospitals in the U.K. Patients: A cohort of 1.267 children aged 3.25 to 6.75 years with confirmed OME. None had previously received surgical intervention. Interventions: Follow-up over a "watchful waiting" period of 12 weeks. Main Outcome Measures: Otoscopy and pure-tone audiometry. Results: Retraction of the pars tensa to the incus or promontory occurred i n 8% of the better-hearing ears and 10% of the poorer-hearing ears. Pars fl accida retraction to the malleus or farther occurred in 4.5% of the better- hearing ears and 5.5% of the poorer-hearing ears. Retractions were not asso ciated with a longer history of hearing problems. Pars tensa or pars flacci da retraction in association with OME did not materially affect the hearing . Pars tensa retractions, followed up over a 12-week period, resolved in 69 % of the better-hearing ears and 65% of the poorer-hearing ears. In 14% and 10% of ears, respectively, the OME had also resolved. Conclusions: There is minimal evidence to support the concept that pars ten sa or pars flaccida retractions are a strong or relevant marker for the sev erity or evolution of OME in children. Prospective studies over a longer pe riod of follow-up are required to confirm this.
