Objectives : To assess the results of myringoplasty in children and to determine which factors independently influence the postoperative results. Study Design : Retrospective study of the anatomic and functional results of 231 consecutive myringoplasties performed in 188 children between 1988 and 1992. Multivariate analysis of poor prognostic factors by cross‐sectional comparison 1 year after surgery. Methods : Myringoplasties were performed via an endaural approach with a fascia temporalis underlay graft. Results : In 216 of 231 ears (93.5%) the tympanic membrane was closed. A good anatomic outcome was considered to have been achieved in 188 ears (81.6%), although in 18 ears (7.8%) seromucous otitis media occurred, in 8 ears (3.5%) a progressive retraction pocket was encountered, and in 2 ears significant lateralization was present. One hundred thirty‐nine (67.5%) of the 206 ears tested in the postoperative period had a postoperative air‐bone gap of 10 dB or less. On average, mean bone conduction remained unaltered. The age of the patient and the size and the location of the perforation did not affect the outcome. Three prognostic factors for an abnormal postoperative tympanic membrane were found, with 95% confidence intervals: inflammatory changes in the middle ear mucosa ( P < .05), contralateral tympanic perforation ( P < .05), and contralateral cholesteatoma ( P < .01). Conclusions : Myringoplasty with underlay grafting of the fascia temporalis in children gives good anatomic and functional results. Inflammatory changes within the middle ear mucosa, contralateral tympanic perforation, and contralateral cholesteatoma independently influence the risk of an abnormal postoperative tympanic membrane. The presence of one of these factors preoperatively should lead to the consideration of alternative, more durable graft material, such as autologous cartilage.
